# LeoFS Input Plugin
|
||||
|
||||
This plugin gathers metrics of the [LEO filesystem][leofs] services
|
||||
_LeoGateway_, _LeoManager_, and _LeoStorage_ via SNMP. Check the
|
||||
[LeoFS system monitoring documentation][docs] for details.
|
||||
|
||||
⭐ Telegraf v0.1.5

## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
||||
|
||||
In addition to the plugin-specific configuration settings, plugins support
|
||||
additional global and plugin configuration settings. These settings are used to
|
||||
modify metrics, tags, and field or create aliases and configure ordering, etc.
|
||||
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.

## Configuration
|

||||
# Read metrics from a LeoFS Server via SNMP
|
||||
[[inputs.leofs]]
|

## An array of URLs of the form:
|
||||
## host [ ":" port]
|
||||
servers = ["127.0.0.1:4010"]
