Telegraf is the Agent for Collecting & Reporting Metrics & Data.
It is part of the TICK stack and is a plugin-driven server agent for collecting and reporting metrics. Telegraf has plugins or integrations to source a variety of metrics directly from the system it’s running on, pull metrics from third-party APIs, or even listen for metrics via a StatsD and Kafka consumer services. It also has output plugins to send metrics to a variety of other datastores, services, and message queues, including InfluxDB, Graphite, OpenTSDB, Datadog, Librato, Kafka, MQTT, NSQ, and many others.
Telegraf collects metrics from one or more applications and stores them in a database of choice.
juju deploy telegrafOutput plugins are destinations were Telegraf writes metrics to:
- InfluxDB
How to add the relation:
juju deploy cs:~chris.macnaughton/influxdb-7
juju add-relation telegraf:influxdb-output influxdb:queryFor the moment only InfluxDB is supported but in the future other databases (f.e. OpenTSDB) will be added to the charm.
When a relation is made with one of the services listed below then Telegraf will collect specific metrics from this application:
- MongoDB
How to add the relation:
juju add-relation telegraf mongodbMore applications will be added in the future.
If your application is not listed in the input or output plugin section then you will not be able to get detailed metrics for that service. It is still possible to get simple system metrics like cpu, memory, disk space, etc. To receive those you need to create a juju-info relation with the service.
