Configuring topology resources for production (IBM Cloud Pak for AIOps on Linux)

Learn how to configure the File observer for more than 600,000 resources.

Configuring the File observer

Additional configuration is required if you are using the File observer for more than 600,000 resources.

If IBM Sales representatives and Business Partners did not use the custom sizing tool to supply you with a custom profile ConfigMap to customize your deployment, then run the following command from a control plane node:

cat <<EOF | oc apply -f -
apiVersion: v1
kind: ConfigMap

If IBM Sales representatives and Business Partners used the custom sizing tool to supply you with a custom profile ConfigMap to customize your deployment, then use the following steps to adjust the value of JVM_ARGS for the File observer to -Xms300M -Xmx1400M:

  1. Log in to a control plane node and then run the following command:

    oc project aiops

  2. Run the following commands to edit your custom profile configmap:

    CUSTOM_SIZE_PROFILE=$(oc get installation.orchestrator.aiops.ibm.com -n aiops -o jsonpath='{.items[0].status.customProfileConfigmap}')
oc edit configmap "${CUSTOM_SIZE_PROFILE}" -n aiops

  3. Adjust the value of JVM_ARGS for the File observer to -Xms300M -Xmx1400M and save your changes.
