The heartbeat endpoint, /pf/heartbeat.ping, returns a customizable OK browser message and an HTTP 200 status indication if the PingFederate server is running.
You can customize the message by modifying the pf.heartbeat.system.monitoring PingFederate property.
If a GET request receives a connection error or an HTTP status code other than 200, the server associated with the endpoint is down or malfunctioning.
Set the pf.heartbeat.system.monitoring property in the
file to true or false.
When pf.heartbeat.system.monitoring is set to false, the /pf/heartbeat.ping endpoint returns OK. When set to true, the /pf/heartbeat.ping endpoint returns all available stats.
- Restart PingFederate.
If you want to customize the information returned by the heartbeat endpoint, edit
the heartbeat.page.template file, located in the
Template customization does not require a restart of PingFederate. For a clustered PingFederate environment, repeat these steps on each node.
If you want to specify percentiles in addition to, or in place of, the default 90th
percentile in the statistics reported on the heartbeat:
- Edit the com.pingidentity.monitoring.MonitoringService.xml file located in the <pf_install>/pingfederate/server/default/data/config-store directory.
Change the value of the
StatisticsPercentilesListitem to the preferred percentile. You can enter a single value, such as 99.9, or multiple values separated by commas, such as 80,90,99.5.Note:
StatisticsPercentilesListitem allows you to customize the percentiles displayed in the heartbeat endpoint response of the metrics ending in
.<StatisticsPercentilesList>.percentile. Percentiles can be a helpful way to understand a metric's distribution and identify patterns or trends over time. They can also be used to set performance targets or to identify bottlenecks in a system.
In the context of server response metrics, you can use percentiles to compare a server's response time to other servers or previous periods. For more information, including a complete list of server metrics and their descriptions, see Liveliness and responsiveness.Setting the
StatisticsPercentilesListitem to 50 will display the 50th percentile of a server's response time in the heartbeat endpoint response. A value of
200milliseconds for the 50th percentile means that 50% of the server's responses were faster than 200 milliseconds, while 50% were slower. Similarly, a value of
500milliseconds for the 95th percentile means that 95% of the server's responses were faster than 500 milliseconds, while 5% were slower.
