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. closes #870 closes #1842 |

Telegraf
Telegraf is an agent written in Go for collecting metrics from the system it's running on, or from other services, and writing them into InfluxDB or other outputs.
Design goals are to have a minimal memory footprint with a plugin system so that developers in the community can easily add support for collecting metrics from well known services (like Hadoop, Postgres, or Redis) and third party APIs (like Mailchimp, AWS CloudWatch, or Google Analytics).
New input and output plugins are designed to be easy to contribute, we'll eagerly accept pull requests and will manage the set of plugins that Telegraf supports. See the contributing guide for instructions on writing new plugins.
Installation:
Linux deb and rpm Packages:
Latest:
- https://dl.influxdata.com/telegraf/releases/telegraf_1.0.1_amd64.deb
- https://dl.influxdata.com/telegraf/releases/telegraf-1.0.1.x86_64.rpm
Latest (arm):

From Source:
Telegraf manages dependencies via gdm, which gets installed via the Makefile if you don't have it already. You also must build with golang version 1.5+.
- Install Go
- Setup your GOPATH
- Run
go get github.com/influxdata/telegraf
- Run
cd $GOPATH/src/github.com/influxdata/telegraf
- Run
make
How to use it:
$ telegraf --help
Telegraf, The plugin-driven server agent for collecting and reporting metrics.
Usage:
telegraf [commands|flags]
The commands & flags are:
config print out full sample configuration to stdout
version print the version to stdout
--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 config > telegraf.conf
# generate config with only cpu input & influxdb output plugins defined
telegraf 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
Configuration
See the configuration guide for a rundown of the more advanced configuration options.
