Update Log Level

ESS services support a subset of log levels supported by Quarkus:

• FATAL

• ERROR

• WARN

• INFO (Default level)

• DEBUG

By default, ESS’ log level is configured to INFO level:

• This outputs logs with severity level INFO and higher (i.e., outputs INFO , WARN , ERROR and FATAL levels).

• This excludes logs with security level below INFO (i.e., excludes DEBUG ).

As part of your infrastructure-as-code deployment, you may wish to control log levels of the deployments using a customization.

For example, when debugging an issue you may temporarily enable DEBUG level logs to get more granular information on system behavior.

To change a service’s log level, you can create an overlay to update the QUARKUS_LOG_LEVEL environment variable.

ESS also supports changing the level of log messages using redaction. See Logging Redaction for details.

Example Debug Logging Customization File

You can use the following procedure to enable DEBUG level logging for pod-provisioning :

1. Go to your ESS installation directory:

   cd ${HOME}/ess

2. Modify the kustomization.yaml (i.e., step 3 of the Applying Your Customizations procedure). Specifically, add the highlighted content to the kustomization.yaml file under the patches key:

Tip If patches list does not exist in kustomization.yaml , add the key patches as well.

# kustomization.yaml in your ESS installation directory
# ...  Preceding content omitted for brevity 
# ...
patches:
  - target:
      kind: Deployment
      name: ess-pod-provision
    patch: |-
      apiVersion: apps/v1
      kind: Deployment
      metadata:
        name: ess-pod-provision
      spec:
        template:
          spec:
            containers:
              - env:
                - name: QUARKUS_LOG_LEVEL
                  value: DEBUG
                name: ess-pod-provision

1. Continue with the rest of the Applying Your Customizations procedure.

Tip Remember to reset the log level when you’re finished debugging.
