To activate this monitor in the Smart Agent, add the following to your agent config:

   ...  # Additional config

For a list of monitor options that are common to all monitors, see Common Configuration.

This monitor has no configuration options.

Metrics

These are the metrics available for this monitor. Metrics that are categorized as container/host (default) are in bold and italics in the list below.

  • protocol_counter.ActiveOpens (cumulative)
    The number of times TCP connections transitioned from the CLOSED state to the SYN-SENT state.

  • protocol_counter.CurrEstab (cumulative)
    The number of TCP connections currently in either ESTABLISHED or CLOSE-WAIT state.

  • protocol_counter.DelayedACKs (cumulative)
    The number of acknowledgements delayed by TCP Delayed Acknowledgement

  • protocol_counter.InDestUnreachs (cumulative)
    The number of ICMP Destination Unreachable messages received

  • protocol_counter.OutSegs (cumulative)
    The total number of segments that have been sent, including those on current connections but excluding those containing only retransmitted octets.

  • protocol_counter.PassiveOpens (cumulative)
    The number of times that a server opened a connection, due to receiving a TCP SYN packet.

  • protocol_counter.RetransSegs (cumulative)
    The total number of segments retransmitted

Non-default metrics (version 4.7.0+)

To emit metrics that are not default, you can add those metrics in the generic monitor-level extraMetrics config option. Metrics that are derived from specific configuration options that do not appear in the above list of metrics do not need to be added to extraMetrics.

To see a list of metrics that will be emitted you can run agent-status monitors after configuring this monitor in a running agent instance.
