Description

Feature Request

Proposal:

I'd like to see implemented the netstat plugin to collect the connection states per port that the system/a service listens on, just like the TCPConns plugin of collectd

Current behavior:

The netstat plugin only gathers the amount of state types.

Desired behavior:

The netstat plugin gathers amount of state types per port.

Use case:

Currently we're using the collectd plugin to show us how much connections each of our dovecot backend nodes is handling. We'd like to replace this with Telegraf.

Contributor guide

Research direction
Study existing Telegraf input plugins, particularly those that parse command output. Look at the netstat command output format and design a parser to extract per port connection states. Follow Telegraf plugin development guide to create a new plugin.
