Metrics

The following table lists the metrics available for this monitor. Metrics that are marked as Included are standard metrics and are monitored by default.

Name Type Included Description
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

To specify custom metrics you want to monitor, add a metricsToInclude filter to the agent configuration, as shown in the code snippet below. The snippet lists all available custom metrics. You can copy and paste the snippet into your configuration file, then delete any custom metrics that you do not want sent.

Note that some of the custom metrics require you to set a flag as well as add them to the list. Check the monitor configuration file to see if a flag is required for gathering additional metrics.
