# LeoFS Input Plugin The LeoFS plugin gathers metrics of LeoGateway, LeoManager, and LeoStorage using SNMP. See [LeoFS Documentation / System Administration / System Monitoring](https://leo-project.net/leofs/docs/admin/system_admin/monitoring/). ## Configuration: ```toml # Sample Config: [[inputs.leofs]] servers = ["127.0.0.1:4010"] ``` ## Measurements & Fields: ### Statistics specific to the internals of LeoManager #### Erlang VM -
