# 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 🏷️ network, server 💻 all [leofs]: https://leo-project.net/leofs/ [docs]: https://leo-project.net/leofs/docs/admin/system_admin/monitoring/ ## 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][CONFIGURATION.md] for more details. [CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins ## Configuration ```toml @sample.conf # 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 -
