097b1e09db http listener refactor 
in this commit:

- chunks out the http request body to avoid making very large
  allocations.
- establishes a limit for the maximum http request body size that the
  listener will accept.
- utilizes a pool of byte buffers to reduce GC pressure.

a65447d22e Use mysql.ParseDSN func instead of url.Parse 
The MySQL DB driver has it's own DSN parsing function. Previously we
were using the url.Parse function, but this causes problems because a
valid MySQL DSN can be an invalid http URL, namely when using some
special characters in the password.

This change uses the MySQL DB driver's builtin ParseDSN function and
applies a timeout parameter natively via that.

Another benefit of this change is that we fail earlier if given an
invalid MySQL DSN.

e96f7a9b12 graphite parser, handle multiple templates empty filter 
Previously, the graphite parser would simply overwrite any template that
had an identical filter to a previous template. This included the empty
filter.

Now we will still overwrite, but first we will sort to make sure that
the most "specific" template always matches.

With this patch bool, float64 and nil values get converted to a string when
their field key is specified in tag_keys. Previously the field was simply
discarded.

* Updated handling of nil for passing tests.

The automated tests are less than trivial to reproduece locally for me,
so I hope CircleCI wonn't mind...

* Updated changelog entries with PR and issue links.

e457b7a8df Source improvement for librato output (#1416) 
* Source improvement for librato output

Build the source from the list of tag instead of a configuration specified
single tag

Graphite Serializer:
* make buildTags public
* make sure not to use empty tags

Librato output:
* Improve Error handling for librato API base on error or debug flag
* Send Metric per Batch (max 300)
* use Graphite BuildTag function to generate source

The change is made that it should be retro compatible

Metric sample:
server=127.0.0.1 port=80 state=leader env=test
measurement.metric_name value
service_n.metric_x

Metric before with source tags set as "server":
source=127.0.0.1
test.80.127_0_0_1.leader.measurement.metric_name
test.80.127_0_0_1.leader.service_n.metric_x

Metric now:
source=test.80.127.0.0.1.leader
measurement.metric_name
service_n.metric_x

As you can see the source in the "new" version is much more precise
That way when filter (only from source) you can filter by env or any other tags

* Using template to specify which tagsusing for source, default concat all
tags

* revert change in graphite serializer

* better documentation, change default for template

* fmt

* test passing with new host as default tags

* use host tag in api integration test

* Limit 80 char per line, change resolution to be a int in the sample

* fmt

* remove resolution, doc for template

* fmt

7b6713b094 Telegraf support for built-in windows service. 
Updated windows dependencies

Updated the windows dependencies so that the versions matched the
dependencies for Mac OS and Linux. Additionally added some that were
complained about being missing at compile time.

Incorporated kardianos/service for management

Incorporated the library github.com/kardianos/service to manage the
service on the various platforms (including Windows). This required an
alternate main function.

The original main function was renamed to reloadLoop (as that is what
the main loop in it does) (it also got a couple of parameters). The
service management library calls it as the main body of the program.

Merged service.go into telegraf.go

Due to compilation issues on Windows, moved the code from service.go
into telegraf.go and removed service.go entirely.

Updated dependencies and fixed Windows service

Updated the dependencies so that it builds properly on Windows,
additionally, fixed the registered command for starting it as
a service (needed to add the config file option). This currently
standardizes it as a C:\telegraf\telegraf.conf on Windows.

Added dependency for github.com/kardianos/service

Removed the common dependencies from _windows file

Removed all the common dependencies from the Godeps_windows file and
modified Makefile to load Godeps and then Godeps_windows when building
for Windows. This should reduce problems caused by the Godeps_windows
file being forgotten when updating dependencies.

Updated CHANGELOG.md with changes

Ran `go fmt ./...` to format code

Removed service library on all but Windows

The service library [kardianos/service](github.com/kardianos/service)
has been disabled on all platforms but windows, as there is already
existing infrastructure for other platforms.

Removed the dependency line for itself

It appears that gdm accidentally added the project itself to the
dependency list. This caused the dependency restoration to select an
earlier version of the project during build.

This only affected windows.
This only affected builds after 020b2c70

Updated documentation for Windows Service

Removed the documentation about using NSSM and added documentation on
installing telegraf directly as a Windows Service.

Added license info for kardianos/service

Added the license information for github.com/kardianos/service which is
licensed under the ZLib license, although that name is never mentioned
the license text matches word for word.

Changed the Windows Config file default location

Updated the default location of the configuration file on Windows from
C:\telegraf\telegraf.conf to C:\Program Files\Telegraf\telegraf.conf.
With this change includes updating the directions, including directing
that the executable be put into that same directory. Additionally, as
noted in the instructions, the location of the config file for the
service may be changed by specifying the location with the `-config`
flag at install time.

Fixed bug - Wrong data type: svcConfig

svcConfig service.Config => svcConfig *service.Config

375710488d Add support for self-signed certs to RabbitMQ input plugin (#1503) 
* add initial support to allow self-signed certs

When using self-signed the metrics collection will fail, this will allow
the user to specify in the input configuration file if they want to skip
certificate verification. This is functionally identical to `curl -k`

At some point this functionality should be moved to the agent as it is
already implemented identically in several different input plugins.

* Add initial comment strings to remove noise

These should be properly fleshed out at some point to ensure
code completeness

* refactor to use generic helper function

* fix import statement against fork

* update changelog

- [#1949](https://github.com/influxdata/telegraf/issues/1949): Fix windows `net` plugin.
## v1.1.1 [unreleased]
### Bugfixes
- [#2023](https://github.com/influxdata/telegraf/issues/2023): Fix issue parsing toml durations with single quotes.
## v1.1.0 [2016-11-07]
### Release Notes
- Telegraf now supports two new types of plugins: processors & aggregators.
- On systemd Telegraf will no longer redirect it's stdout to /var/log/telegraf/telegraf.log.
On most systems, the logs will be directed to the systemd journal and can be
accessed by `journalctl -u telegraf.service`. Consult the systemd journal
documentation for configuring journald. There is also a [`logfile` config option](https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf#L70)
available in 1.1, which will allow users to easily configure telegraf to
continue sending logs to /var/log/telegraf/telegraf.log.

## v1.0 [2016-09-08]
### Release Notes
**Breaking Change** The SNMP plugin is being deprecated in it's current form.
There is a [new SNMP plugin](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/snmp)
which fixes many of the issues and confusions
of its predecessor. For users wanting to continue to use the deprecated SNMP
plugin, you will need to change your config file from `[[inputs.snmp]]` to
`[[inputs.snmp_legacy]]`. The configuration of the new SNMP plugin is _not_
backwards-compatible.
**Breaking Change**: Aerospike main server node measurements have been renamed
aerospike_node. Aerospike namespace measurements have been renamed to
aerospike_namespace. They will also now be tagged with the node_name

- Telegraf now supports being installed as an official windows service,

evaluated at every flush interval, rather than once at startup. This makes it
consistent with the behavior of `collection_jitter`.

## v1.0 beta 1 [2016-06-07]
### Release Notes
- `flush_jitter` behavior has been changed. The random jitter will now be
evaluated at every flush interval, rather than once at startup. This makes it
consistent with the behavior of `collection_jitter`.
- All AWS plugins now utilize a standard mechanism for evaluating credentials.
This allows all AWS plugins to support environment variables, shared credential
files & profiles, and role assumptions. See the specific plugin README for
details.
- The AWS CloudWatch input plugin can now declare a wildcard value for a metric
dimension. This causes the plugin to read all metrics that contain the specified
dimension key regardless of value. This is used to export collections of metrics
without having to know the dimension values ahead of time.
- The AWS CloudWatch input plugin can now be configured with the `cache_ttl`
attribute. This configures the TTL of the internal metric cache. This is useful
in conjunction with wildcard dimension values as it will control the amount of
time before a new metric is included by the plugin.

## Processor Plugins
This section is for developers who want to create a new processor plugin.
### Processor Plugin Guidelines
* A processor must conform to the [`telegraf.Processor`](https://godoc.org/github.com/influxdata/telegraf#Processor) interface.
* Processors should call `processors.Add` in their `init` function to register themselves.
See below for a quick example.
* To be available within Telegraf itself, plugins must add themselves to the
`github.com/influxdata/telegraf/plugins/processors/all/all.go` file.
* The `SampleConfig` function should return valid toml that describes how the
processor can be configured. This is include in `telegraf -sample-config`.
* The `Description` function should say in one line what this processor does.
### Processor Example
```go
package printer
// printer.go
import (
"fmt"
"github.com/influxdata/telegraf"
"github.com/influxdata/telegraf/plugins/processors"
)
type Printer struct {
}
var sampleConfig = `

func (p *Printer) SampleConfig() string {
return sampleConfig
}
func (p *Printer) Description() string {
return "Print all metrics that pass through this filter."
}
func (p *Printer) Apply(in ...telegraf.Metric) []telegraf.Metric {
for _, metric := range in {
fmt.Println(metric.String())
}
return in
}
func init() {
processors.Add("printer", func() telegraf.Processor {
return &Printer{}
})
}
```
## Aggregator Plugins
This section is for developers who want to create a new aggregator plugin.
### Aggregator Plugin Guidelines
* A aggregator must conform to the [`telegraf.Aggregator`](https://godoc.org/github.com/influxdata/telegraf#Aggregator) interface.
* Aggregators should call `aggregators.Add` in their `init` function to register themselves.
See below for a quick example.
* To be available within Telegraf itself, plugins must add themselves to the
`github.com/influxdata/telegraf/plugins/aggregators/all/all.go` file.
* The `SampleConfig` function should return valid toml that describes how the
aggregator can be configured. This is include in `telegraf -sample-config`.
* The `Description` function should say in one line what this aggregator does.
* The Aggregator plugin will need to keep caches of metrics that have passed
through it. This should be done using the builtin `HashID()` function of each
metric.
* When the `Reset()` function is called, all caches should be cleared.
### Aggregator Example
```go
package min
// min.go
import (
"github.com/influxdata/telegraf"
"github.com/influxdata/telegraf/plugins/aggregators"
)

## If true drop_original will drop the original metrics and
## only send aggregates.
drop_original = false

Telegraf, The plugin-driven server agent for collecting and reporting metrics.
See usage with:
Usage:
telegraf <flags>
The flags are:
-config <file> configuration file to load
-test gather metrics once, print them to stdout, and exit
-sample-config print out full sample configuration to stdout
-config-directory directory containing additional *.conf files
-input-filter filter the input plugins to enable, separator is :
-output-filter filter the output plugins to enable, separator is :
-usage print usage for a plugin, ie, 'telegraf -usage mysql'
-debug print metrics as they're generated to stdout
-quiet run in quiet mode
-version print the version to stdout
Examples:
# generate a telegraf config file:
telegraf -sample-config > telegraf.conf
# generate config with only cpu input & influxdb output plugins defined
telegraf -sample-config -input-filter cpu -output-filter influxdb
# run a single telegraf collection, outputing metrics to stdout
telegraf -config telegraf.conf -test
# run telegraf with all plugins defined in config file
telegraf -config telegraf.conf
# run telegraf, enabling the cpu & memory input, and influxdb output plugins
telegraf -config telegraf.conf -input-filter cpu:mem -output-filter influxdb
```
telegraf --help
```
### Generate a telegraf config file:
```
telegraf config > telegraf.conf
```
### Generate config with only cpu input & influxdb output plugins defined
```
telegraf --input-filter cpu --output-filter influxdb config
```
### Run a single telegraf collection, outputing metrics to stdout
```
telegraf --config telegraf.conf -test

const usage = `Telegraf, The plugin-driven server agent for collecting and reporting metrics.
Usage:
telegraf <flags>
telegraf [commands|flags]
The flags are:
The commands & flags are:
-config <file> configuration file to load
-test gather metrics once, print them to stdout, and exit
-sample-config print out full sample configuration to stdout
-config-directory directory containing additional *.conf files
-input-filter filter the input plugins to enable, separator is :
-input-list print all the plugins inputs
-output-filter filter the output plugins to enable, separator is :
-output-list print all the available outputs
-usage print usage for a plugin, ie, 'telegraf -usage mysql'
-debug print metrics as they're generated to stdout
-quiet run in quiet mode
-version print the version to stdout
config print out full sample configuration to stdout
version print the version to stdout
In addition to the -config flag, telegraf will also load the config file from
an environment variable or default location. Precedence is:
1. -config flag
2. $TELEGRAF_CONFIG_PATH environment variable
3. $HOME/.telegraf/telegraf.conf
4. /etc/telegraf/telegraf.conf
--config <file> configuration file to load
--test gather metrics once, print them to stdout, and exit
--config-directory directory containing additional *.conf files
--input-filter filter the input plugins to enable, separator is :
--output-filter filter the output plugins to enable, separator is :
--usage print usage for a plugin, ie, 'telegraf --usage mysql'
--debug print metrics as they're generated to stdout
--quiet run in quiet mode
Examples:
# generate a telegraf config file:
telegraf -sample-config > telegraf.conf
telegraf config > telegraf.conf
# generate config with only cpu input & influxdb output plugins defined
telegraf -sample-config -input-filter cpu -output-filter influxdb
telegraf --input-filter cpu --output-filter influxdb config
# run a single telegraf collection, outputing metrics to stdout
telegraf -config telegraf.conf -test
telegraf --config telegraf.conf -test
# run telegraf with all plugins defined in config file
telegraf -config telegraf.conf
telegraf --config telegraf.conf
# run telegraf, enabling the cpu & memory input, and influxdb output plugins
telegraf -config telegraf.conf -input-filter cpu:mem -output-filter influxdb

# Telegraf Configuration
## Generating a Configuration File
A default Telegraf config file can be generated using the -sample-config flag:
```
telegraf -sample-config > telegraf.conf
```
To generate a file with specific inputs and outputs, you can use the
-input-filter and -output-filter flags:
```
telegraf -sample-config -input-filter cpu:mem:net:swap -output-filter influxdb:kafka
```
You can see the latest config file with all available plugins here:
[telegraf.conf](https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf)
## Generating a Configuration File
A default Telegraf config file can be auto-generated by telegraf:
```
telegraf config > telegraf.conf
```
To generate a file with specific inputs and outputs, you can use the
--input-filter and --output-filter flags:
```
telegraf --input-filter cpu:mem:net:swap --output-filter influxdb:kafka config
```
## Environment Variables
Environment variables can be used anywhere in the config file, simply prepend
them with $. For strings the variable must be within quotes (ie, "$STR_VAR"),
for numbers and booleans they should be plain (ie, $INT_VAR, $BOOL_VAR)
## `[global_tags]` Configuration
# Global Tags
Global tags can be specified in the `[global_tags]` section of the config file
in key="value" format. All metrics being gathered on this host will be tagged
with the tags specified here.

* **precision**: By default, precision will be set to the same timestamp order
as the collection interval, with the maximum being 1s. Precision will NOT
be used for service inputs, such as logparser and statsd. Valid values are
"ns", "us" (or "µs"), "ms", "s".

* **hostname**: Override default hostname, if empty use os.Hostname().
* **omit_hostname**: If true, do no set the "host" tag in the telegraf agent.
## Input Configuration
The following config parameters are available for all inputs:
* **interval**: How often to gather this metric. Normal plugins use a single
global interval, but if one particular input should be run less or more often,
you can configure that here.
* **name_override**: Override the base name of the measurement.

## Output Configuration
There are no generic configuration options available for all outputs.
## Aggregator Configuration
The following config parameters are available for all aggregators:
* **period**: The period on which to flush & clear each aggregator. All metrics
that are sent with timestamps outside of this period will be ignored by the
aggregator.
* **delay**: The delay before each aggregator is flushed. This is to control
how long for aggregators to wait before receiving metrics from input plugins,
in the case that aggregators are flushing and inputs are gathering on the
same interval.
* **drop_original**: If true, the original metric will be dropped by the
aggregator and will not get sent to the output plugins.
* **name_override**: Override the base name of the measurement.
(Default is the name of the input).
* **name_prefix**: Specifies a prefix to attach to the measurement name.
* **name_suffix**: Specifies a suffix to attach to the measurement name.
* **tags**: A map of tags to apply to a specific input's measurements.

# Running Telegraf as a Windows Service
If you have tried to install Go binaries as Windows Services with the **sc.exe**
tool you may have seen that the service errors and stops running after a while.
Telegraf natively supports running as a Windows Service. Outlined below is are
the general steps to set it up.
**NSSM** (the Non-Sucking Service Manager) is a tool that helps you in a
[number of scenarios](http://nssm.cc/scenarios) including running Go binaries
that were not specifically designed to run only in Windows platforms.
1. Obtain the telegraf windows distribution
2. Create the directory `C:\Program Files\Telegraf` (if you install in a different
location simply specify the `-config` parameter with the desired location)
3. Place the telegraf.exe and the telegraf.conf config file into `C:\Program Files\Telegraf`
4. To install the service into the Windows Service Manager, run the following in PowerShell as an administrator (If necessary, you can wrap any spaces in the file paths in double quotes ""):
## NSSM Installation via Chocolatey
```
> C:\"Program Files"\Telegraf\telegraf.exe --service install
```
You can install [Chocolatey](https://chocolatey.org/) and [NSSM](http://nssm.cc/)
with these commands
5. Edit the configuration file to meet your needs
6. To check that it works, run:
```powershell
iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
choco install -y nssm
```
```
> C:\"Program Files"\Telegraf\telegraf.exe --config C:\"Program Files"\Telegraf\telegraf.conf --test
```
## Installing Telegraf as a Windows Service with NSSM
7. To start collecting data, run:
You can download the latest Telegraf Windows binaries (still Experimental at
the moment) from [the Telegraf Github repo](https://github.com/influxdata/telegraf).
```
> net start telegraf
```
Then you can create a C:\telegraf folder, unzip the binary there and modify the
**telegraf.conf** sample to allocate the metrics you want to send to **InfluxDB**.
## Other supported operations
Once you have NSSM installed in your system, the process is quite straightforward.
You only need to type this command in your Windows shell
Telegraf can manage its own service through the --service flag:
```powershell
nssm install Telegraf c:\telegraf\telegraf.exe -config c:\telegraf\telegraf.config
```
| Command | Effect |
|------------------------------------|-------------------------------|
| `telegraf.exe --service install` | Install telegraf as a service |
| `telegraf.exe --service uninstall` | Remove the telegraf service |
| `telegraf.exe --service start` | Start the telegraf service |
| `telegraf.exe --service stop` | Stop the telegraf service |
And now your service will be installed in Windows and you will be able to start and
stop it gracefully

Collects performance metrics from the MON and OSD nodes in a Ceph storage cluster.
The plugin works by scanning the configured SocketDir for OSD and MON socket files. When it finds
a MON socket, it runs **ceph --admin-daemon $file perfcounters_dump**. For OSDs it runs **ceph --admin-daemon $file perf dump**

This gatherer works by scanning the configured SocketDir for OSD and MON socket files. When it finds

The resulting JSON is parsed and grouped into collections, based on top-level key. Top-level keys are
used as collection tags, and all sub-keys are flattened. For example:

This gatherer works by invoking ceph commands against the cluster thus only requires the ceph client, valid
ceph configuration and an access key to function (the ceph_config and ceph_user configuration variables work
in conjunction to specify these prerequisites). It may be run on any server you wish which has access to
the cluster. The currently supported commands are:

# HAproxy Input Plugin
[HAproxy](http://www.haproxy.org/) input plugin gathers metrics directly from any running HAproxy instance. It can do so by using CSV generated by HAproxy status page or from admin socket(s).
### Configuration:
```toml
# SampleConfig
[[inputs.haproxy]]
servers = ["http://1.2.3.4/haproxy?stats", "/var/run/haproxy*.sock"]
```
Server addresses need to explicitly start with 'http' if you wish to use HAproxy status page. Otherwise, address will be assumed to be an UNIX socket and protocol (if present) will be discarded.
Following examples will all resolve to the same socket:
```
socket:/var/run/haproxy.sock
unix:/var/run/haproxy.sock
foo:/var/run/haproxy.sock
/var/run/haproxy.sock
```
When using socket names, wildcard expansion is supported so plugin can gather stats from multiple sockets at once.
If no servers are specified, then the default address of `http://127.0.0.1:1936/haproxy?stats` will be used.
### Measurements & Fields:
Plugin will gather measurements outlined in [HAproxy CSV format documentation](https://cbonte.github.io/haproxy-dconv/1.5/configuration.html#9.1).
### Tags:
- All measurements have the following tags:
- server - address of server data is gathered from
- proxy - proxy name as reported in `pxname`
- sv - service name as reported in `svname`

# HTTP listener service input plugin
The HTTP listener is a service input plugin that listens for messages sent via HTTP POST.
The plugin expects messages in the InfluxDB line-protocol ONLY, other Telegraf input data formats are not supported.
The intent of the plugin is to allow Telegraf to serve as a proxy/router for the /write endpoint of the InfluxDB HTTP API.
When chaining Telegraf instances using this plugin, CREATE DATABASE requests receive a 200 OK response with message body `{"results":[]}` but they are not relayed. The output configuration of the Telegraf instance which ultimately submits data to InfluxDB determines the destination database.
See: [Telegraf Input Data Formats](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#influx).
Example: curl -i -XPOST 'http://localhost:8186/write' --data-binary 'cpu_load_short,host=server01,region=us-west value=0.64 1434055562000000000'
### Configuration:
This is a sample configuration for the plugin.
```toml
# # Influx HTTP write listener
[[inputs.http_listener]]
## Address and port to host HTTP listener on
service_address = ":8186"
## timeouts
read_timeout = "10s"
write_timeout = "10s"

# Iptables Plugin
The iptables plugin gathers packets and bytes counters for rules within a set of table and chain from the Linux's iptables firewall.
Rules are identified through associated comment. Rules without comment are ignored.
The iptables command requires CAP_NET_ADMIN and CAP_NET_RAW capabilities. You have several options to grant telegraf to run iptables:
* Run telegraf as root. This is strongly discouraged.
* Configure systemd to run telegraf with CAP_NET_ADMIN and CAP_NET_RAW. This is the simplest and recommended option.
* Configure sudo to grant telegraf to run iptables. This is the most restrictive option, but require sudo setup.
### Using systemd capabilities
You may run `systemctl edit telegraf.service` and add the following:
```
[Service]
CapabilityBoundingSet=CAP_NET_RAW CAP_NET_ADMIN
AmbientCapabilities=CAP_NET_RAW CAP_NET_ADMIN
```
Since telegraf will fork a process to run iptables, `AmbientCapabilities` is required to transmit the capabilities bounding set to the forked process.
### Using sudo
You may edit your sudo configuration with the following:
```sudo
telegraf ALL=(root) NOPASSWD: /usr/bin/iptables -nvL *
```
### Configuration:
```toml
# use sudo to run iptables
use_sudo = false
# defines the table to monitor:
table = "filter"
# defines the chains to monitor:
chains = [ "INPUT" ]
```
### Measurements & Fields:
- iptables
- pkts (integer, count)
- bytes (integer, bytes)
### Tags:
- All measurements have the following tags:
- table
- chain
- ruleid
The `ruleid` is the comment associated to the rule.
### Example Output:
```
$ iptables -nvL INPUT
Chain INPUT (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
100 1024 ACCEPT tcp -- * * 192.168.0.0/24 0.0.0.0/0 tcp dpt:22 /* ssh */
42 2048 ACCEPT tcp -- * * 192.168.0.0/24 0.0.0.0/0 tcp dpt:80 /* httpd */
```
```
$ ./telegraf -config telegraf.conf -input-filter iptables -test
iptables,table=filter,chain=INPUT,ruleid=ssh pkts=100i,bytes=1024i 1453831884664956455
