Prometheus exporter for netstat metrics. This exporter will give details about send queue, receive queues ,local port, foreign address etc.

The above script runs netstat -tlnap commands under hood to get the metrics, so this will work fine on any unix box. You need root access to run the script as netstat require root access to give details about all ports.

usage: netstat_exporter.py [-h] [-q QUEUELIMIT] [-i INTERVAL] [-p PORT]

A netstat exporter

options:
  -h, --help            show this help message and exit
  -q QUEUELIMIT, --QueueLimit QUEUELIMIT
                        Minimum queue length to report (default: 0)
  -i INTERVAL, --interval INTERVAL
                        Minimum interval before getting stats again (default: 1)
  -p PORT, --port PORT  Port on which it will export data. (default: 8100)

For example python3 netstat_exporter.py -q 100 -i 10

This will generate stats at http://localhost:8100/ , it will exclude results having queue size less than 100.

This can be easily viewed in grafana dashboard.
