LeoFS Input Plugin

This plugin gathers metrics of the LEO filesystem services LeoGateway, LeoManager, and LeoStorage via SNMP. Check the LeoFS system monitoring documentation 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 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"]
