Ververica Platform lets you configure the log level for platform components through the Helm values.yaml file. You can set a global log level that applies to all components, and override it for individual components as needed.

Configuration

Global Log Level

Set global.logLevel to apply a log level to all platform components:

YAML

1global:
2  logLevel: INFO

Per-Component Override

Set <component>.logLevel to override the global level for a specific component:

YAML

1global:
2  logLevel: INFO
3
4appManager:
5  logLevel: TRACE

In this example, AppManager runs at TRACE while all other components run at INFO.

Valid Log Levels

Level	Description
Level	Description
TRACE	Most detailed. Includes all lower-priority messages.
DEBUG	Detailed diagnostic information.
INFO	Informational messages about normal operation. Default.
WARN	Potential issues that do not stop the component.
ERROR	Error conditions and exceptions.

Levels are listed in ascending order of urgency. Setting a level captures all messages at that level and above. For example, WARN captures WARN and ERROR messages only.

Note

The default log level is INFO. Each component's logback.xml configuration consumes the logLevel environment variable with a fallback of INFO, so omitting global.logLevel from values.yaml is equivalent to setting it to INFO.

Apply Changes

After editing values.yaml, apply the changes by running:

BASH

1helm upgrade --install <RELEASE_NAME> \
2  oci://registry.ververica.cloud/platform-charts/ververica-platform \
3  --version 3.1.1 \
4  --namespace <NAMESPACE> \
5  --values values.yaml

Components whose log level changed restart automatically during the upgrade.

Verify

To confirm the log level is in effect, inspect live logs for a component pod:

BASH

1kubectl logs -n <NAMESPACE> <POD_NAME> --tail=50

At TRACE or DEBUG level, output includes significantly more entries than at INFO. At WARN or ERROR, only warning and error messages appear.
