--- title: Telegraf Documentation description: Telegraf plugin for collecting metrics from LeoFS url: https://docs.influxdata.com/telegraf/v1/input-plugins/leofs/ estimated_tokens: 2281 product: Telegraf version: v1 --- - Telegraf v0.1.5+ # LeoFS Input Plugin This plugin gathers metrics of the [LEO filesystem](https://leo-project.net/leofs/) services *LeoGateway*, *LeoManager*, and *LeoStorage* via SNMP. Check the [LeoFS system monitoring documentation](https://leo-project.net/leofs/docs/admin/system_admin/monitoring/) for details. **Introduced in:** Telegraf v0.1.5 **Tags:** network, server **OS support:** all ## Global configuration options Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details. ## Configuration ```toml # 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"] ``` ## Metrics ### Statistics specific to the internals of LeoManager #### Erlang VM of LeoManager -
