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 $GOPATH/src/github.com/influxdb + git clone git@github.com:/influxdb + +Retaining the directory structure `$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 " to zoom in. Or "list " 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 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: + +``` +.... +``` +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.

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.

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 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 object can then be used to store statistics.

Combining many series into a single series (i.e. removing 1 or more tag dimensions to make queries more efficient) +2. Aggregating and downsampling series + +The purpose of both types of continuous queries is to duplicate or downsample data automatically in the background to make querying thier results fast and efficient. Think of them as another way to create indexes on data. + +Generally, there are continuous queries that create copyies of data into another measurement or tagset and queries that downsample and aggregate data. The only difference between the two types is if the query has a `GROUP BY time` clause. + +Before we get to the continuous query examples, we need to define the `INTO` syntax of queries. + +### INTO + +`INTO` is a method for running a query and having it output into either another measurement name, retention policy, or database. The syntax looks like this: + +```sql +SELECT * +INTO [.] [ON ] +FROM +[WHERE ...] +[GROUP BY ...] +``` + +The syntax states that the retention policy, database, where clause, and group by clause are all optional. If a retention policy isn't specified, the database's default retention policy will be written into. If the database isn't specified, the database the query is running from will be written into. + +By selecting specific fields, `INTO` can merge many series into one that will go into a new either a new measurement, retention policy, or database. For example: + +```sql +SELECT mean(value) as value, region +INTO "1h.cpu_load" +FROM cpu_load +GROUP BY time(1h), region +``` + +That will give 1h summaries of the mean value of the `cpu_load` for each `region`. Specifying `region` in the `GROUP BY` clause is unnecessary since having it in the `SELECT` clause forces it to be grouped by that tag, we've just included it in the example for clarity. + +With `SELECT ... INTO`, fields will be written as fields and tags will be written as tags. + +### Continuous Query Syntax + +The `INTO` queries run once. Continuous queries will turn `INTO` queries into something that run in the background in the cluster. They're kind of like triggers in SQL. + +```sql +CREATE CONTINUOUS QUERY "1h_cpu_load" +ON database_name +BEGIN + SELECT mean(value) as value, region + INTO "1h.cpu_load" + FROM cpu_load + GROUP BY time(1h), region +END +``` + +Or chain them together: + +```sql +CREATE CONTINUOUS QUERY "10m_event_count" +ON database_name +BEGIN + SELECT count(value) + INTO "10m.events" + FROM events + GROUP BY time(10m) +END + +-- this selects from the output of one continuous query and outputs to another series +CREATE CONTINUOUS QUERY "1h_event_count" +ON database_name +BEGIN + SELECT sum(count) as count + INTO "1h.events" + FROM events + GROUP BY time(1h) +END +``` + +Or multiple aggregations from all series in a measurement. This example assumes you have a retention policy named `1h`. + +```sql +CREATE CONTINUOUS QUERY "1h_cpu_load" +ON database_name +BEGIN + SELECT mean(value), percentile(80, value) as percentile_80, percentile(95, value) as percentile_95 + INTO "1h.cpu_load" + FROM cpu_load + GROUP BY time(1h), * +END +``` + +The `GROUP BY *` indicates that we want to group by the tagset of the points written in. The same tags will be written to the output series. The multiple aggregates in the `SELECT` clause (percentile, mean) will be written in as fields to the resulting series. + +Showing what continuous queries we have: + +```sql +LIST CONTINUOUS QUERIES +``` + +Dropping continuous queries: + +```sql +DROP CONTINUOUS QUERY +ON +``` + +### Security + +To create or drop a continuous query, the user must be an admin. + +### Limitations + +In order to prevent cycles and endless copying of data, the following limitation is enforced on continuous queries at create time: + +*The output of a continuous query must go to either a different measurement or to a different retention policy.* + +In theory they'd still be able to create a cycle with multiple continuous queries. We should check for these and disallow. + +## Proposed Architecture + +Continuous queries should be stored in the metastore cluster wide. That is, they amount to database schema that should be stored in every server in a cluster. + +Continuous queries will have to be handled in a different way for two different use cases: those that simply copy data (CQs without a group by time) and those that aggregate and downsample data (those with a group by time). + +### No group by time + +For CQs that have no `GROUP BY time` clause, they should be evaluated at the data node as part of the write. The single write should create any other writes for the CQ and submit those in the same request to the brokers to ensure that all writes succeed (both the original and the new CQ writes) or none do. + +I imagine the process going something like this: + +1.
