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.

⭐ Telegraf v0.1.5 🏷️ network, server 💻 all

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"]
