| # 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"] | ||
| ``` | ||
