# Mesos Input Plugin
|
||||||
|
|
||||||
|
This input plugin gathers metrics from Mesos (*currently only Mesos masters*).
|
||||||
|
For more information, please check the [Mesos Observability Metrics](http://mesos.apache.org/documentation/latest/monitoring/) page.
|
||||||
|
|
||||||
|
### Configuration:
|
||||||
|
|
||||||
|
```toml
|
||||||
|
# Telegraf plugin for gathering metrics from N Mesos masters
|
||||||
|
[[inputs.mesos]]
|
||||||
|
# Timeout, in ms.
|
||||||
|
timeout = 100
|
||||||
|
# A list of Mesos masters. e.g. master1:5050, master2:5080, etc.
|
||||||
|
# The port can be skipped if using the default (5050)
|
||||||
|
# Default value is localhost:5050.
|
||||||
|
masters = ["localhost:5050"]
|
||||||
|
# Metrics groups to be collected.
|
||||||
|
# Default, all enabled.
|
||||||
|
master_collections = ["resources","master","system","slaves","frameworks","messages","evqueue","registrar"]
|
||||||
|
```
|
||||||
