Monitor a domain and publish logs

After the Oracle SOA Suite domain is set up, you can:

Monitor the Oracle SOA Suite instance using Prometheus and Grafana

Using the WebLogic Monitoring Exporter you can scrape runtime information from a running Oracle SOA Suite instance and monitor them using Prometheus and Grafana.

Prerequisite: Before setting up monitoring, make sure that Prometheus and Grafana are deployed on the Kubernetes cluster.

Deploy Prometheus and Grafana

Refer to the compatibility matrix of Kube Prometheus and clone the release version of the kube-prometheus repository according to the Kubernetes version of your cluster.

  1. Clone the kube-prometheus repository:

    $ git clone https://github.com/coreos/kube-prometheus.git

  2. Change to folder kube-prometheus and enter the following commands to create the namespace and CRDs, and then wait for their availability before creating the remaining resources:

    $ cd kube-prometheus
$ kubectl create -f manifests/setup
$ until kubectl get servicemonitors --all-namespaces ; do date; sleep 1; echo ""; done
$ kubectl create -f manifests/

  3. kube-prometheus requires all nodes in the Kubernetes cluster to be labeled with kubernetes.io/os=linux. If any node is not labeled with this, then you need to label it using the following command:

    $ kubectl label nodes --all kubernetes.io/os=linux

  4. Enter the following commands to provide external access for Grafana, Prometheus, and Alertmanager:

    $ kubectl patch svc grafana -n monitoring --type=json -p '[{"op": "replace", "path": "/spec/type", "value": "NodePort" },{"op": "replace", "path": "/spec/ports/0/nodePort", "value": 32100 }]'

$ kubectl patch svc prometheus-k8s -n monitoring --type=json -p '[{"op": "replace", "path": "/spec/type", "value": "NodePort" },{"op": "replace", "path": "/spec/ports/0/nodePort", "value": 32101 }]'

$ kubectl patch svc alertmanager-main -n monitoring --type=json -p '[{"op": "replace", "path": "/spec/type", "value": "NodePort" },{"op": "replace", "path": "/spec/ports/0/nodePort", "value": 32102 }]'

    Note:

    • 32100 is the external port for Grafana
    • 32101 is the external port for Prometheus
    • 32102 is the external port for Alertmanager

Set up monitoring

Publish WebLogic Server logs into Elasticsearch

You can publish the WebLogic Server logs to Elasticsearch using the WebLogic logging exporter and interact with them in Kibana. See Publish logs to Elasticsearch.

WebLogic Server logs can also be published to Elasticsearch using Fluentd. See Fluentd configuration steps.
