=== The {application_monitoring_operator}
|
|
|
|
Before using the Operator to install {project_name} or create components, we recommend that you install the {application_monitoring_operator}, which tracks Operator activity. To view metrics for the Operator, you can use the Grafana Dashboard and Prometheus Alerts from the {application_monitoring_operator}. For example, you can view metrics such as the number of controller runtime reconciliation loops, the reconcile loop time, and errors.
|
|
|
|
The {project_operator} integration with the {application_monitoring_operator} requires no action. You only need to install the {application_monitoring_operator} in the cluster.
|
|
|
|
==== Installing the {application_monitoring_operator}
|
|
|
|
.Prerequisites
|
|
|
|
* The {project_operator} is installed.
|
|
|
|
* You have cluster-admin permission or an equivalent level of permissions granted by an administrator.
|
|
|
|
.Procedure
|
|
|
|
. Install the {application_monitoring_operator} by using the link:{application_monitoring_operator_installation_link}[documentation].
|
|
|
|
. Annotate the namespace used for the {project_operator} installation. For example:
|
|
+
|
|
[source,bash,subs=+attributes]
|
|
----
|
|
{create_cmd_brief} label namespace <namespace> monitoring-key=middleware
|
|
----
|
|
|
|
. Log into the OpenShift web console.
|
|
|
|
. Confirm monitoring is working by searching for Prometheus and Grafana route in the `application-monitoring` namespace.

|
==== Viewing Operator Metrics
|
|
|
|
Grafana and Promotheus each provide graphical information about Operator activities.
|
|
|
|
* The Operator installs a pre-defined Grafana Dashboard as shown here:
|
|
+
|
|
.Grafana Dashboard

|
[NOTE]
|
|
====
|
|
If you make customizations, we recommend that you clone the Grafana Dashboard so that your changes are not overwritten during an upgrade.
|
|
====
|
|
|
|
* The Operator installs a set of pre-defined Prometheus Alerts as shown here:
|
|
+
|
|
.Prometheus Alerts
