+Contributing to InfluxDB
+========================
+
+Bug reports
+---------------
+Before you file an issue, please search existing issues in case it has already been filed, or perhaps even fixed. If you file an issue, please include the following.
+* Full details of your operating system (or distribution) e.g. 64-bit Ubuntu 14.04.
+* The version of InfluxDB you are running
+* Whether you installed it using a pre-built package, or built it from source.
+* A small test case, if applicable, that demonstrates the issues.
+
+Remember the golden rule of bug reports: **The easier you make it for us to reproduce the problem, the faster it will get fixed.**
+If you have never written a bug report before, or if you want to brush up on your bug reporting skills, we recommend reading [Simon Tatham's essay "How to Report Bugs Effectively."](http://www.chiark.greenend.org.uk/~sgtatham/bugs.html)
+
+Test cases should be in the form of `curl` commands. For example:
+```
+# create database
+curl -G http://localhost:8086/query --data-urlencode "q=CREATE DATABASE mydb"
+
+# create retention policy
+curl -G http://localhost:8086/query --data-urlencode "q=CREATE RETENTION POLICY myrp ON mydb DURATION 365d REPLICATION 1 DEFAULT"
+
+# write data
+curl -X POST http://localhost:8086/write --data-urlencode "db=mydb" --data-binary "cpu,region=useast,host=server_1,service=redis value=61" 
+
+# Delete a Measurement
+curl -G http://localhost:8086/query  --data-urlencode 'db=mydb' --data-urlencode 'q=DROP MEASUREMENT cpu'
+
+# Query the Measurement
+# Bug: expected it to return no data, but data comes back.
+curl -G http://localhost:8086/query  --data-urlencode 'db=mydb' --data-urlencode 'q=SELECT * from cpu'
+```
+**If you don't include a clear test case like this, your issue may not be investigated, and may even be closed**. If writing the data is too difficult, please zip up your data directory and include a link to it in your bug report.
+
+Please note that issues are *not the place to file general questions* such as "how do I use collectd with InfluxDB?" Questions of this nature should be sent to the [Google Group](https://groups.google.com/forum/#!forum/influxdb), not filed as issues. Issues like this will be closed.
+
+Feature requests
+---------------
+We really like to receive feature requests, as it helps us prioritize our work. Please be clear about your requirements, as incomplete feature requests may simply be closed if we don't understand what you would like to see added to InfluxDB.
+
+Contributing to the source code
+---------------
+
+InfluxDB follows standard Go project structure. This means that all
+your go development are done in `$GOPATH/src`. GOPATH can be any
+directory under which InfluxDB and all its dependencies will be
+cloned. For more details on recommended go project's structure, see
+[How to Write Go Code](http://golang.org/doc/code.html) and
+[Go: Best Practices for Production Environments](http://peter.bourgon.org/go-in-production/), or you can just follow
+the steps below.
+
+Submitting a pull request
+------------
+To submit a pull request you should fork the InfluxDB repository, and make your change on a feature branch of your fork. Then generate a pull request from your branch against *master* of the InfluxDB repository. Include in your pull request details of your change -- the why *and* the how -- as well as the testing your performed. Also, be sure to run the test suite with your change in place. Changes that cause tests to fail cannot be merged.
+
+There will usually be some back and forth as we finalize the change, but once that completes it may be merged.
+
+To assist in review for the PR, please add the following to your pull request comment:
+
+```md
+- [ ] CHANGELOG.md updated
+- [ ] Rebased/mergable
+- [ ] Tests pass
+- [ ] Sign [CLA](http://influxdb.com/community/cla.html) (if not already signed)
+```
+
+Use of third-party packages
+------------
+A third-party package is defined as one that is not part of the standard Go distribution. Generally speaking we prefer to minimize our use of third-party packages, and avoid them unless absolutely necessarly. We'll often write a little bit of code rather than pull in a third-party package. Of course, we do use some third-party packages -- most importantly we use [BoltDB](https://github.com/boltdb/bolt) as the storage engine. So to maximise the chance your change will be accepted by us, use only the standard libaries, or the third-party packages we have decided to use.
+
+For rationale, check out the post [The Case Against Third Party Libraries](http://blog.gopheracademy.com/advent-2014/case-against-3pl/).
+
+Signing the CLA
+---------------
+
+If you are going to be contributing back to InfluxDB please take a
+second to sign our CLA, which can be found
+[on our website](http://influxdb.com/community/cla.html).
+
+Installing Go
+-------------
+InfluxDB requires Go 1.5 or greater.
+
+At InfluxDB we find gvm, a Go version manager, useful for installing Go. For instructions
+on how to install it see [the gvm page on github](https://github.com/moovweb/gvm).
+
+After installing gvm you can install and set the default go version by
+running the following:
+
+    gvm install go1.5
+    gvm use go1.5 --default
+
+Revision Control Systems
+-------------
+Go has the ability to import remote packages via revision control systems with the `go get` command.  To ensure that you can retrieve any remote package, be sure to install the following rcs software to your system.
+Currently the project only depends on `git` and `mercurial`.
+
+* [Install Git](http://git-scm.com/book/en/Getting-Started-Installing-Git)
+* [Install Mercurial](http://mercurial.selenic.com/wiki/Download)
+
+Getting the source
+------
+Setup the project structure and fetch the repo like so:
+
+    mkdir $HOME/gocodez
+    export GOPATH=$HOME/gocodez
+    go get github.com/influxdb/influxdb
+
+You can add the line `export GOPATH=$HOME/gocodez` to your bash/zsh file to be set for every shell instead of having to manually run it everytime.
+
+Cloning a fork
+-------------
+If you wish to work with fork of InfluxDB, your own fork for example, you must still follow the directory structure above. But instead of cloning the main repo, instead clone your fork. Follow the steps below to work with a fork:
+
+    export GOPATH=$HOME/gocodez
+    mkdir -p $GOPATH/src/github.com/influxdb
+    cd $GOPATH/src/github.com/influxdb
+    git clone git@github.com:<username>/influxdb
+
+Retaining the directory structure `$GOPATH/src/github.com/influxdb` is necessary so that Go imports work correctly.
+
+Pre-commit checks
+-------------
+
+We have a pre commit hook to make sure code is formatted properly
+and vetted before you commit any changes. We strongly recommend using the pre
+commit hook to guard against accidentally committing unformatted
+code. To use the pre-commit hook, run the following:
+
+    cd $GOPATH/src/github.com/influxdb/influxdb
+    cp .hooks/pre-commit .git/hooks/
+
+In case the commit is rejected because it's not formatted you can run
+the following to format the code:
+
+```
+go fmt ./...
+go vet ./...
+```
+
+To install go vet, run the following command:
+```
+go get golang.org/x/tools/cmd/vet
+```
+
+NOTE: If you have not installed mercurial, the above command will fail.  See [Revision Control Systems](#revision-control-systems) above.
+
+For more information on `go vet`, [read the GoDoc](https://godoc.org/golang.org/x/tools/cmd/vet).
+
+Build and Test
+-----
+
+Make sure you have Go installed and the project structure as shown above. To then build the project, execute the following commands:
+
+```bash
+cd $GOPATH/src/github.com/influxdb
+go get -u -f -t ./...
+go build ./...
+```
+
+To then install the binaries, run the following command. They can be found in `$GOPATH/bin`. Please note that the InfluxDB binary is named `influxd`, not `influxdb`.
+
+```bash
+go install ./...
+```
+
+To set the version and commit flags during the build pass the following to the build command:
+
+```bash
+-ldflags="-X main.version=$VERSION -X main.branch=$BRANCH -X main.commit=$COMMIT"
+```
+
+where `$VERSION` is the version, `$BRANCH` is the branch, and `$COMMIT` is the git commit hash.
+
+If you want to build packages, see `package.sh` help:
+```bash
+package.sh -h
+```
+
+To run the tests, execute the following command:
+
+```bash
+cd $GOPATH/src/github.com/influxdb/influxdb
+go test -v ./...
+
+# run tests that match some pattern
+go test -run=TestDatabase . -v
+
+# run tests and show coverage
+go test -coverprofile /tmp/cover . && go tool cover -html /tmp/cover
+```
+
+To install go cover, run the following command:
+```
+go get golang.org/x/tools/cmd/cover
+```
+
+Generated Google Protobuf code
+-----------------
+Most changes to the source do not require that the generated protocol buffer code be changed. But if you need to modify the protocol buffer code, you'll first need to install the protocol buffers toolchain.
+
+First install the [protocol buffer compiler](https://developers.google.com/protocol-buffers/
+) 2.6.1 or later for your OS:
+
+Then install the go plugins:
+
+```bash
+go get github.com/gogo/protobuf/proto
+go get github.com/gogo/protobuf/protoc-gen-gogo
+go get github.com/gogo/protobuf/gogoproto
+```
+
+Finally run, `go generate` after updating any `*.proto` file:
+
+```bash
+go generate ./...
+```
+**Trouleshooting**
+
+If generating the protobuf code is failing for you, check each of the following:
+ * Ensure the protobuf library can be found. Make sure that `LD_LIBRRARY_PATH` includes the directory in which the library `libprotoc.so` has been installed.
+ * Ensure the command `protoc-gen-gogo`, found in `GOPATH/bin`, is on your path. This can be done by adding `GOPATH/bin` to `PATH`.
+
+Profiling
+-----
+When troubleshooting problems with CPU or memory the Go toolchain can be helpful. You can start InfluxDB with CPU or memory profiling turned on. For example:
+
+```sh
+# start influx with profiling
+./influxd -cpuprofile influxd.prof
+# run queries, writes, whatever you're testing
+# open up pprof
+go tool pprof influxd influxd.prof
+# once inside run "web", opens up browser with the CPU graph
+# can also run "web <function name>" to zoom in. Or "list <function name>" to see specific lines
+```
+
+Continuous Integration testing
+-----
+InfluxDB uses CirceCI for continuous integration testing. To see how the code is built and tested, check out [this file](https://github.com/influxdb/influxdb/blob/master/circle-test.sh). It closely follows the build and test process outlined above. You can see the exact version of Go InfluxDB uses for testing by consulting that file.

+# Docker Setup
+========================
+
+This document describes how to build and run a minimal InfluxDB container under Docker.   Currently, it has only been tested for local development and assumes that you have a working docker environment.
+
+## Building Image
+
+To build a docker image for InfluxDB from your current checkout, run the following:
+
+```
+$ ./build-docker.sh
+```
+
+This script uses the `golang:1.5` image to build a fully static binary of `influxd` and then adds it to a minimal `scratch` image.
+
+To build the image using a different version of go:
+
+```
+$ GO_VER=1.4.2 ./build-docker.sh
+```
+
+Available version can be found [here](https://hub.docker.com/_/golang/).
+
+## Single Node Container
+
+This will start an interactive, single-node, that publishes the containers port `8086` and `8088` to the hosts ports `8086` and `8088` respectively.  This is identical to starting `influxd` manually.
+
+```
+$ docker run -it -p 8086:8086 -p 8088:8088 influxdb
+```
+
+## Multi-Node Cluster
+
+This will create a simple 3-node cluster.  The data is stored within the container and will be lost when the container is removed.  This is only useful for test clusters.
+
+The `HOST_IP` env variable should be your host IP if running under linux or the virtualbox VM IP if running under OSX.  On OSX, this would be something like: `$(docker-machine ip dev)` or `$(boot2docker ip)` depending on which docker tool you are using.
+
+```
+$ export HOST_IP=<your host/VM IP>
+$ docker run -it -p 8086:8086 -p 8088:8088 influxdb -hostname $HOST_IP:8088
+$ docker run -it -p 8186:8086 -p 8188:8088 influxdb -hostname $HOST_IP:8188 -join $HOST_IP:8088
+$ docker run -it -p 8286:8086 -p 8288:8088 influxdb -hostname $HOST_IP:8288 -join $HOST_IP:8088
+```

+The top level name is called a measurement. These names can contain any characters. Then there are field names, field values, tag keys and tag values, which can also contain any characters. However, if the measurement, field, or tag contains any character other than [A-Z,a-z,0-9,_], or if it starts with a digit, it must be double-quoted. Therefore anywhere a measurement name, field name, field value, tag name, or tag value appears it should be wrapped in double quotes.

+
+-- drop a database

+```
+where `<duration>` is either `INF` for infinite retention, or an integer followed by the desired unit of time: u,ms,s,m,h,d,w for microseconds, milliseconds, seconds, minutes, hours, days, or weeks, respectively. `<replication>` must be an integer.
+
+If present, `DEFAULT` sets the retention policy as the default retention policy for writes and reads.

+where `<privilege> := READ | WRITE | All `. 
+
+Authentication must be enabled in the influxdb.conf file for user permissions to be in effect.
+
+By default, newly created users have no privileges to any databases.
+
+Cluster administration privileges automatically grant full read and write permissions to all databases, regardless of subsequent database-specific privilege revocation statements.

+# Continuous Queries
+
+Continous queries are going to be inspired by MySQL `TRIGGER` syntax:
+
+http://dev.mysql.com/doc/refman/5.0/en/trigger-syntax.html
+
+Instead of having automatically-assigned ids, named continuous queries allows for some level of duplication prevention,
+particularly in the case where creation is scripted.
+
+## Create

+    CREATE CONTINUOUS QUERY <name> AS SELECT ... FROM ...
+
+## Destroy
+
+    DROP CONTINUOUS QUERY <name>

+## List

+# InfluxDB [![Circle CI](https://circleci.com/gh/influxdb/influxdb/tree/master.svg?style=svg)](https://circleci.com/gh/influxdb/influxdb/tree/master)
+
+## An Open-Source, Distributed, Time Series Database
+
+> InfluxDB v0.9.0 is now out. Going forward, the 0.9.x series of releases will not make breaking API changes or breaking changes to the underlying data storage. However, 0.9.0 clustering should be considered an alpha release.
+
+InfluxDB is an open source **distributed time series database** with
+**no external dependencies**. It's useful for recording metrics,
+events, and performing analytics.
+
+## Features
+
+* Built-in [HTTP API](http://influxdb.com/docs/v0.9/concepts/reading_and_writing_data.html) so you don't have to write any server side code to get up and running.
+* Data can be tagged, allowing very flexible querying.
+* SQL-like query language.
+* Clustering is supported out of the box, so that you can scale horizontally to handle your data.
+* Simple to install and manage, and fast to get data in and out.
+* It aims to answer queries in real-time. That means every data point is
+  indexed as it comes in and is immediately available in queries that
+  should return in < 100ms.
+
+## Getting Started
+*The following directions apply only to the 0.9.0 release or building from the source on master.*
+
+### Building
+
+You don't need to build the project to use it - you can use any of our
+[pre-built packages](http://influxdb.com/download/index.html) to install InfluxDB. That's
+the recommended way to get it running. However, if you want to contribute to the core of InfluxDB, you'll need to build.
+For those adventurous enough, you can
+[follow along on our docs](http://github.com/influxdb/influxdb/blob/master/CONTRIBUTING.md).
+
+### Starting InfluxDB
+* `service influxdb start` if you have installed InfluxDB using an official Debian or RPM package.
+* `systemctl start influxdb` if you have installed InfluxDB using an official Debian or RPM package, and are running a distro with `systemd`. For example, Ubuntu 15 or later.
+* `$GOPATH/bin/influxd` if you have built InfluxDB from source.
+
+### Creating your first database
+
+```
+curl -G 'http://localhost:8086/query' --data-urlencode "q=CREATE DATABASE mydb"
+```
+
+### Insert some data
+```
+curl -XPOST 'http://localhost:8086/write?db=mydb' \
+-d 'cpu,host=server01,region=uswest load=42 1434055562000000000'
+
+curl -XPOST 'http://localhost:8086/write?db=mydb' \
+-d 'cpu,host=server02,region=uswest load=78 1434055562000000000'
+
+curl -XPOST 'http://localhost:8086/write?db=mydb' \
+-d 'cpu,host=server03,region=useast load=15.4 1434055562000000000'
+```
+
+### Query for the data
+```JSON
+curl -G http://localhost:8086/query?pretty=true --data-urlencode "db=mydb" \
+--data-urlencode "q=SELECT * FROM cpu WHERE host='server01' AND time < now - 1d"
+```
+
+### Analyze the data
+```JSON
+curl -G http://localhost:8086/query?pretty=true --data-urlencode "db=mydb" \
+--data-urlencode "q=SELECT mean(load) FROM cpu WHERE region='uswest'"
+```
+
+## Helpful Links
+
+* Understand the [design goals and motivations of the project](http://influxdb.com/docs/v0.9/introduction/overview.html).
+* Follow the [getting started guide](http://influxdb.com/docs/v0.9/introduction/getting_started.html) to find out how to install InfluxDB, start writing more data, and issue more queries - in just a few minutes.
+* See the  [HTTP API documentation to start writing a library for your favorite language](http://influxdb.com/docs/v0.9/concepts/reading_and_writing_data.html).

+# Server Integration Tests
+
+Currently, the file `server_test.go` has integration tests for single node scenarios.
+At some point we'll need to add cluster tests, and may add them in a different file, or 
+rename `server_test.go` to `server_single_node_test.go` or something like that.
+
+## What is in a test?
+
+Each test is broken apart effectively into the following areas:
+
+- Write sample data
+- Use cases for table driven test, that include a command (typically a query) and an expected result.
+
+When each test runs it does the following:
+
+- init: determines if there are any writes and if so, writes them to the in-memory database
+- queries: iterate through each query, executing the command, and comparing the results to the expected result.
+
+## Idempotent - Allows for parallel tests
+
+Each test should be `idempotent`, meaining that its data will not be affected by other tests, or use cases within the table tests themselves.
+This allows for parallel testing, keeping the test suite total execution time very low.
+
+### Basic sample test
+

+}
+```
+
+Let's break this down:
+
+In this test, we first tell it to run in parallel with the `t.Parallel()` call.
+
+We then open a new server with:
+
+```go
+s := OpenServer(NewConfig(), "")
+defer s.Close()
+```
+
+If needed, we create a database and default retention policy.  This is usually needed
+when inserting and querying data.  This is not needed if you are testing commands like `CREATE DATABASE`, `SHOW DIAGNOSTICS`, etc.
+
+```go
+if err := s.CreateDatabaseAndRetentionPolicy("db0", newRetentionPolicyInfo("rp0", 1, 1*time.Hour)); err != nil {
+	t.Fatal(err)
+}
+```
+
+Next, set up the write data you need:
+
+```go
+writes := []string{
+	fmt.Sprintf("cpu,host=server01 value=100,core=4 %d", mustParseTime(time.RFC3339Nano, "2000-01-01T00:00:00Z").UnixNano()),
+	fmt.Sprintf("cpu1,host=server02 value=50,core=2 %d", mustParseTime(time.RFC3339Nano, "2015-01-01T00:00:00Z").UnixNano()),
+}
+```
+Create a new test with the database and retention policy:
+
+```go
+test := NewTest("db0", "rp0")
+```
+
+Send in the writes:
+```go
+test.write = strings.Join(writes, "\n")
+```
+
+Add some queries (the second one is mocked out to show how to add more than one):
+
+```go
+test.addQueries([]*Query{
+	&Query{
+		name:    "measurement in one shard but not another shouldn't panic server",
+		command: `SELECT host,value  FROM db0.rp0.cpu`,
+		exp:     `{"results":[{"series":[{"name":"cpu","tags":{"host":"server01"},"columns":["time","value"],"values":[["2000-01-01T00:00:00Z",100]]}]}]}`,
+	},
+	&Query{
+		name:    "another test here...",
+		command: `Some query command`,
+		exp:     `the expected results`,
+	},
+}...)
+```
+
+The rest of the code is boilerplate execution code.  It is purposefully not refactored out to a helper
+to make sure the test failure reports the proper lines for debugging purposes.
+
+#### Running the tests
+
+To run the tests:
+
+```sh
+go test ./cmd/influxd/run -parallel 500 -timeout 10s
+```
+
+#### Running a specific test
+
+```sh
+go test ./cmd/influxd/run -parallel 500 -timeout 10s -run TestServer_Query_Fill
+```
+
+#### Verbose feedback
+
+By default, all logs are silenced when testing.  If you pass in the `-v` flag, the test suite becomes verbose, and enables all logging in the system
+
+```sh
+go test ./cmd/influxd/run -parallel 500 -timeout 10s -run TestServer_Query_Fill -v
+```

+# Import/Export
+
+## Exporting from 0.8.9
+
+Version `0.8.9` of InfluxDB adds support to export your data to a format that can be imported into `0.9.3` and later.
+
+Note that `0.8.9` can be found here:
+
+```
+http://get.influxdb.org.s3.amazonaws.com/influxdb_0.8.9_amd64.deb
+http://get.influxdb.org.s3.amazonaws.com/influxdb-0.8.9-1.x86_64.rpm
+```
+
+### Design
+
+`0.8.9` exports raw data to a flat file that includes two sections, `DDL` and `DML`.  You can choose to export them independently (see below).
+
+The `DDL` section contains the sql commands to create databases and retention policies.  the `DML` section is [line protocol](https://github.com/influxdb/influxdb/blob/master/tsdb/README.md) and can be directly posted to the [http endpoint](https://influxdb.com/docs/v0.9/guides/writing_data.html) in `0.9`.  Remember that batching is important and we don't recommend batch sizes over 5k.
+
+You need to specify a database and shard group when you export.
+
+To list out your shards, use the following http endpoint:
+
+`/cluster/shard_spaces`
+
+example:
+```sh
+http://username:password@localhost:8086/cluster/shard_spaces
+```
+
+Then, to export a database with then name "metrics" and a shard space with the name "default", issue the following curl command:
+
+```sh
+curl -o export http://username:password@http://localhost:8086/export/metrics/default
+```
+
+Compression is supported, and will result in a significantly smaller file size.
+
+Use the following command for compression:
+```sh
+curl -o export.gz --compressed http://username:password@http://localhost:8086/export/metrics/default
+```
+
+You can also export just the `DDL` with this option:
+
+```sh
+curl -o export.ddl http://username:password@http://localhost:8086/export/metrics/default?l=ddl
+```
+
+Or just the `DML` with this option:
+
+```sh
+curl -o export.dml.gz --compressed http://username:password@http://localhost:8086/export/metrics/default?l=dml
+```
+
+### Assumptions
+
+- Series name mapping follows these [guidelines](https://influxdb.com/docs/v0.8/advanced_topics/schema_design.html)
+- Database name will map directly from `0.8` to `0.9`
+- Shard Spaces map to Retention Policies
+- Shard Space Duration is ignored, as in `0.9` we determine shard size automatically
+- Regex is used to match the correct series names and only exports that data for the database
+- Duration becomes the new Retention Policy duration
+
+- Users are not migrated due to inability to get passwords.  Anyone using users will need to manually set these back up in `0.9`
+
+### Upgrade Recommendations
+
+It's recommended that you upgrade to `0.9.3` first and have all your writes going there.  Then, on the `0.8.X` instances, upgrade to `0.8.9`.
+
+It is important that when exporting you change your config to allow for the http endpoints not timing out.  To do so, make this change in your config:
+
+```toml
+# Configure the http api
+[api]
+read-timeout = "0s"
+```
+
+### Exceptions
+
+If a series can't be exported to tags based on the guidelines mentioned above,
+we will insert the entire series name as the measurement name.  You can either 
+allow that to import into the new InfluxDB instance, or you can do your own 
+data massage on it prior to importing it.
+
+For example, if you have the following series name:
+
+```
+metric.disk.c.host.server01.single
+```
+
+It will export as exactly thta as the measurement name and no tags:
+
+```
+metric.disk.c.host.server01.single
+```
+
+### Export Metrics
+
+When you export, you will now get comments inline in the `DML`:
+
+`# Found 999 Series for export`
+
+As well as count totals for each series exported:
+
+`# Series FOO - Points Exported: 999`
+
+With a total at the bottom:
+
+`# Points Exported: 999`
+
+You can grep the file that was exported at the end to get all the export metrics:
+
+`cat myexport | grep Exported`
+
+## Importing
+
+Version `0.9.3` of InfluxDB adds support to import your data from version `0.8.9`.
+
+## Caveats
+
+For the export/import to work, all requisites have to be met.  For export, all series names in `0.8` should be in the following format:
+
+```
+<tagName>.<tagValue>.<tagName>.<tagValue>.<measurement>
+```
+for example:
+```
+az.us-west-1.host.serverA.cpu
+```
+or any number of tags 
+```
+building.2.temperature
+```
+
+Additionally, the fields need to have a consistent type (all float64, int64, etc) for every write in `0.8`.  Otherwise they have the potential to fail writes in the import.
+See below for more information.
+
+## Running the import command
+ 
+ To import via the cli, you can specify the following command:
+
+ ```sh
+ influx -import -path=metrics-default.gz -compressed
+ ```
+
+ If the file is not compressed you can issue it without the `-compressed` flag:
+
+ ```sh
+ influx -import -path=metrics-default
+ ```
+
+ To redirect failed import lines to another file, run this command:
+
+ ```sh
+ influx -import -path=metrics-default.gz -compressed > failures
+ ```
+
+ The import will use the line protocol in batches of 5,000 lines per batch when sending data to the server.
+ 
+### Throttiling the import
+ 
+ If you need to throttle the import so the database has time to ingest, you can use the `-pps` flag.  This will limit the points per second that will be sent to the server.
+ 
+  ```sh
+ influx -import -path=metrics-default.gz -compressed -pps 50000 > failures
+ ```
+ 
+ Which is stating that you don't want MORE than 50,000 points per second to write to the database. Due to the processing that is taking place however, you will likely never get exactly 50,000 pps, more like 35,000 pps, etc. 
+
+## Understanding the results of the import
+
+During the import, a status message will write out for every 100,000 points imported and report stats on the progress of the import:
+
+```
+2015/08/21 14:48:01 Processed 3100000 lines.  Time elapsed: 56.740578415s.  Points per second (PPS): 54634
+```
+
+ The batch will give some basic stats when finished:
+
+ ```sh
+ 2015/07/29 23:15:20 Processed 2 commands
+ 2015/07/29 23:15:20 Processed 70207923 inserts
+ 2015/07/29 23:15:20 Failed 29785000 inserts
+ ```
+
+ Most inserts fail due to the following types of error:
+
+ ```sh
+ 2015/07/29 22:18:28 error writing batch:  write failed: field type conflict: input field "value" on measurement "metric" is type float64, already exists as type integer
+ ```
+
+ This is due to the fact that in `0.8` a field could get created and saved as int or float types for independent writes.  In `0.9` the field has to have a consistent type.

+# System Monitoring
+_This functionality should be considered experimental and is subject to change._
+
+_System Monitoring_ means all statistical and diagnostic information made availabe to the user of InfluxDB system, about the system itself. Its purpose is to assist with troubleshooting and performance analysis of the database itself.
+
+## Statistics vs. Diagnostics
+A distinction is made between _statistics_ and _diagnostics_ for the purposes of monitoring. Generally a statistical quality is something that is being counted, and for which it makes sense to store persistently for historical analysis. Diagnostic information is not necessarily numerical, and may not make sense to store.
+
+An example of statistical information would be the number of points received over UDP, or the number of queries executed. Examples of diagnostic information would be a list of current Graphite TCP connections, the version of InfluxDB, or the uptime of the process.
+
+## System Statistics
+`SHOW STATS` displays statisics about subsystems within the running `influxd` process. Statistics include points received, points indexed, bytes written to disk, TCP connections handled etc. These statistics are all zero when the InfluxDB process starts.
+
+All statistics are written, by default, by each node to a "monitor" database within the InfluxDB system, allowing analysis of aggregated statistical data using the standard InfluxQL language. This allows users to track the performance of their system. Importantly, this allows cluster-level statistics to be viewed, since by querying the monitor database, statistics from all nodes may be queried. This can be a very powerful approach for troubleshooting your InfluxDB system and understanding its behaviour.
+
+## System Diagnostics
+`SHOW DIAGNOSTICS` displays various diagnostic information about the `influxd` process. This information is not stored persistently within the InfluxDB system.
+
+## Standard expvar support
+All statistical information is available at HTTP API endpoint `/debug/vars`, in [expvar](https://golang.org/pkg/expvar/) format, allowing external systems to monitor an InfluxDB node. By default, the full path to this endpoint is `http://localhost:8086/debug/vars`.
+
+## Configuration
+The `monitor` module allows the following configuration:
+
+ * Whether to write statistical and diagnostic information to an InfluxDB system. This is enabled by default.
+ * The name of the database to where this information should be written. Defaults to `_internal`. The information is written to the default retention policy for the given database. 
+ * The name of the retention policy, along with full configuration control of the retention policy, if the default retention policy is not suitable.
+ * The rate at which this information should be written. The default rate is once every 10 seconds.
+
+# Design and Implementation
+
+A new module named `monitor` supports all basic statistics and diagnostic functionality. This includes:
+
+ * Allowing other modules to register statistics and diagnostics information, allowing it to be accessed on demand by the `monitor` module.
+ * Serving the statistics and diagnostic information to the user, in response to commands such as `SHOW DIAGNOSTICS`.
+ * Expose standard Go runtime information such as garbage collection statistics.
+ * Make all collected expvar data via HTTP, for collection by 3rd-party tools.
+ * Writing the statistical information to the "monitor" database, for query purposes.
+
+## Registering statistics and diagnostics
+
+To export statistical information with the `monitor` system, code simply calls `influxdb.NewStatistics()` and receives an `expvar.Map` instance in response. This object can then be used to store statistics. To register diagnostic information, `monitor.RegisterDiagnosticsClient` is called, passing a `influxdb.monitor.DiagsClient` object to `monitor`.
+
+## expvar
+Statistical information is gathered by each package using [expvar](https://golang.org/pkg/expvar). Each package registers a map using its package name.
+
+Due to the nature of `expvar`, statistical information is reset to its initial state when a server is restarted.
