Integrating prometheus with Policy components
With this change, all PF components can export prometheus metrics by default. The prometheus metrics servlet will be running on /metrics servletPath.. If the metrics shouldn't be exported, just add a flag "promethus": false in the restServerParameters of default configuration file. This brings up prometheus servlet on /metrics servletPath. Also as part of standard servlet support, "servletUriPath" and "servletClass" are 2 other fields added to RestServerParameters which can be used to add standard servlets. This can be revisited later if needed. Basically, any servlet can be added by passing these fields, for example, to add prometheus metrics servlet on /test/metrics, add the below to restServerParameters: "servletUriPath": "/test/metrics", "servletClass": "io.prometheus.client.exporter.MetricsServlet" In addition, we can later go to individual components and add more metrics, say for e.g., deployedPoliciesCounter/undeployedPoliciesCounter etc on PAP, executedEvents/failedEvents etc on PDP and so on. This will look something like below, for e.g. in policy-pap component: io.prometheus.client.Counter counter = Counter.build() .name("policies_deployed_total") .help("Number of policies deployed.").register() Whenever a policy is deployed, just call counter.inc() Usage of code like above in the individual component will expose such data as well as part of the exposed metrics.
