Common REST monitoring

Common REST is the ForgeRock® Common REST framework. AM exposes an endpoint that lets REST clients gather information about your AM installation in JSON format.

When enabled, AM makes the Common REST-formatted metrics available at the /json/metrics/api endpoint.

For example, to query all monitoring metrics:

$ curl \
--request GET \
--header 'Content-Type: application/json' \
--header 'iPlanetDirectoryPro: P8Eri6d…xAAA.*' \
'https://openam.example.com:8443/openam/json/metrics/api?_queryFilter=true&_prettyPrint=true'
{
  "result" : [ {
    "_id" : "session.authentication-client-based.get-matching-sessions.failure",
    "count" : 0,
    "max" : 0.0,
    "mean" : 0.0,
    "min" : 0.0,
    "p50" : 0.0,
    "p75" : 0.0,
    "p95" : 0.0,
    "p98" : 0.0,
    "p99" : 0.0,
    "p999" : 0.0,
    "stddev" : 0.0,
    "m15_rate" : 0.0,
    "m1_rate" : 0.0,
    "m5_rate" : 0.0,
    "mean_rate" : 0.0,
    "duration_units" : "milliseconds",
    "rate_units" : "calls/second",
    "total" : 0.0,
    "_type" : "timer"
  },
  …

To output values for a specific metric, use the format /json/metric/api/metric name.

For example:

$ curl \
--request GET \
--header 'Content-Type: application/json' \
--header 'iPlanetDirectoryPro: P8Eri6d…xAAA.*' \
'https://openam.example.com:8443/openam/json/metrics/api/authentication.success'
{
    "_id":"authentication.success",
    "m15_rate":2.3882880682497324E-4,
    "m1_rate":1.0818067450729532E-12,
    "m5_rate":3.057223961594952E-5,
    "mean_rate":1.072595825176473E-4,
    "units":"events/second",
    "total":9.0,
    "count":9,
    "_type":"summary"
}
