LeoFS Input Plugin
The LeoFS plugin gathers metrics of LeoGateway, LeoManager, and LeoStorage using SNMP. See LeoFS Documentation / System Administration / System Monitoring.
Global configuration options
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 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"]
