PingFederate Server

Liveliness and responsiveness

One of the simpler methods for monitoring the performance of a PingFederate deployment involves determining whether the PingFederate Server is available and responsive. To help you identify the status of a server, PingFederate provides a heartbeat request endpoint.

Heartbeat endpoint

If the PingFederate server is running, the process of sending a request to the endpoint /pf/heartbeat.ping returns an HTTP 200 status. If the request times out or requires an extended amount of time to return, the server might be overloaded or experiencing other difficulties.

If a request requires more than two or three seconds to return, multiple factors in your PingFederate deployment might be responsible. We recommend that you develop a baseline for the desired response time by testing the heartbeat endpoint of your deployment at various times. This endpoint can be useful when load balancing a cluster of PingFederate instances. Some load balancers can alter the number of requests that are sent to a particular server based on the response code received, or the responsiveness of requests that are made to the heartbeat endpoint.

The output of the heartbeat endpoint can be modified to provide performance-related information, such as CPU and memory usage, and response times. The response metrics can help you make better auto-scaling decisions. The map size metrics can help you recognize performance issues.

The following example shows a report containing a sample of the PingFederate server metrics available from the heartbeat endpoint. This response does not include examples of every field. For a complete list of fields, see the server metrics table below.

To customize the statistics window period, change the value of the StatisticsWindowSecs parameter in the <pf_install>/pingfederate/server/default/data/config-store/com.pingidentity.monitoring.MonitoringService.xml file. This file also lets you specify additional JMX MBean attributes that will be made available to the heartbeat page templates.

For more information, see Customizing the heartbeat message.

Response-time logging

By default, the audit logs record the processing time for each transaction. With audit logging enabled, you can identify the speed with which PingFederate processes the following transaction types:

  • Single sign-on (SSO)

  • OAuth

  • Security token services (STS)

Depending on your logging configuration, audit logging might not log any transactions. For more information, see Security audit logging.

The following provides examples of the default audit log.
