# Overview
This is a subordinate charm to deploy telegraf metrics agent to collect metrics from all services deployed in the environment.
For details about telegraf see: https://github.com/influxdata/telegraf
# Usage
Deploy telegraf alonside your service, and also a time series storage (in this case, influxdb)
juju deploy telegraf
juju deploy influxdb
juju deploy some-service
Add the relations:
juju add-relation telegraf:juju-info some-service:juju-info
juju add-relation telegraf:influxdb-api influxdb:api
# Configuration
By default there is no output plugin configured, but a basic set of input plugins are setup, which can be overriden with inputs_config charm config.
The only output plugin supported via relation is influxdb, any other output plugin needs to be configured manually (via juju set)
To use a different metrics storage, e.g: graphite. the plugin configuration needs to be set as a base64 string in outputs_config configuration.
For exmaple, save the following config to a file:
[[outputs.graphite]]
servers = ["10.0.3.231:2003"]
prefix = "juju_local.devel.telegraf"
timeout = 10
And then
juju set telegraf outputs_config="$(cat graphite-output.conf | base64)"
This will make telegraf agents to send the metrics to the graphite instance.
