= Configuring Node Observability Operator scripting
|
|
|
|
.Prerequisites
|
|
|
|
* You have installed the Node Observability Operator.
|
|
* You have created the `NodeObservability` custom resource (CR).
|
|
* You have access to the cluster with `cluster-admin` privileges.
|
|
|
|
.Procedure
|
|
|
|
. Create a file named `nodeobservabilityrun-script.yaml` that contains the following content:
|
|
+
|
|
[source,yaml]
|
|
----
|
|
apiVersion: nodeobservability.olm.openshift.io/v1alpha2
|
|
kind: NodeObservabilityRun
|
|
metadata:
|
|
name: nodeobservabilityrun-script
|
|
namespace: node-observability-operator
|
|
spec:
|
|
nodeObservabilityRef:
|
|
name: cluster
|
|
type: scripting
|
|

|
[IMPORTANT]
|
|
====
|
|
You can request only the following scripts:
|
|
|
|
* `metrics.sh`
|
|
* `network-metrics.sh` (uses `monitor.sh`)
|
|
====
|
|
|
|
. Trigger the scripting by creating the `NodeObservabilityRun` resource with the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc apply -f nodeobservabilityrun-script.yaml
|
|
----
|
|
|
|
. Review the status of the `NodeObservabilityRun` scripting by running the following command:
|
|
+
|
|
[source,terminal]
|
|
----
|
|
$ oc get nodeobservabilityrun nodeobservabilityrun-script -o yaml | yq '.status.conditions'
|
|

|
|

|

The scripting is complete once `Status` is `True` and `Type` is `Finished`.
|
|
|
|
. Retrieve the scripting data from the root path of the container by running the following bash script:
|
|
+
|
|
[source,bash]
|

----
|
|
#!/bin/bash
|
|
|
|
RUN=$(oc get nodeobservabilityrun --no-headers | awk '{print $1}')
|
|
|
|
for a in $(oc get nodeobservabilityruns.nodeobservability.olm.openshift.io/${RUN} -o json | jq .status.agents[].name); do
|
|
echo "agent ${a}"
|
|
agent=$(echo ${a} | tr -d "\"\'\`")
|
|
base_dir=$(oc exec "${agent}" -c node-observability-agent -- bash -c "ls -t | grep node-observability-agent" | head -1)
|
|
echo "${base_dir}"
|
|
mkdir -p "/tmp/${agent}"
|
|
for p in $(oc exec "${agent}" -c node-observability-agent -- bash -c "ls ${base_dir}"); do
|
|
f="/${base_dir}/${p}"
|
|
echo "copying ${f} to /tmp/${agent}/${p}"
|
|
oc exec "${agent}" -c node-observability-agent -- cat ${f} > "/tmp/${agent}/${p}"
|
|
done

done
