How to configure logging

Operator logging

Log level

To adjust logging level of the operator, you can use operator.args in chart template value as described in Additional configuration.

For example, to set log level to INFO and DEBUG for requests package, you can use the following value:

operator:
  args: ["--log.level=INFO", "--log.level=requests=DEBUG"]

Log format

By default, operator logs in pretty format.

To switch logging format to the JSON, you can use operator.args in chart template value:

operator:
  args: ["--log.format=json"]

ArangoDeployment logging

By default, ArangoDeployment logs in pretty format.

To switch logging format to the JSON we need to pass --log.use-json-format argument to the ArangoDB server in the deployment:

apiVersion: database.arangodb.com/v1
kind: ArangoDeployment
metadata:
  name: single
spec:
  mode: Single
  single:
    args:
      - --log.use-json-format
      - --log.level=INFO
      - --log.level=backup=TRACE
