# Mesos Input Plugin
2016-06-09 10:33:14 +00:00
This input plugin gathers metrics from Mesos.
2016-02-16 08:18:59 +00:00
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]]
2016-06-09 10:33:14 +00:00
## Timeout, in ms.
2016-02-16 08:18:59 +00:00
timeout = 100
2016-06-09 10:33:14 +00:00
## A list of Mesos masters.
2016-02-16 08:18:59 +00:00
masters = ["localhost:5050"]
2016-06-09 10:33:14 +00:00
## Master metrics groups to be collected, by default, all enabled.
master_collections = [
"resources",
"master",
"system",
"agents",
"frameworks",
"tasks",
"messages",
"evqueue",
"registrar",
]
## A list of Mesos slaves, default is []
# slaves = []
## Slave metrics groups to be collected, by default, all enabled.
# slave_collections = [
# "resources",
# "agent",
# "system",
# "executors",
# "tasks",
# "messages",
# ]
## Include mesos tasks statistics, default is false
# slave_tasks = true

```

By default this plugin is not configured to gather metrics from mesos. Since a mesos cluster can be deployed in numerous ways it does not provide any default
values. User needs to specify master/slave nodes this plugin will gather metrics from. Additionally, enabling `slave_tasks` will allow
gathering metrics from tasks running on specified slaves (this option is disabled by default).
