Key Netstat metrics to use for monitoring

Some of the key metrics from Netstat that you should monitor include:

  • Unit counts for measurements - For each of the 12 states the Netstate Telegraf plugin will provide the number count of each current connection type.
  • UDP socket connection counts - Netstat also provides the number of active UDP connections.
