Deploying fluentbit for logging

Logging feature is introduced in 10.5 version of NetBackup for Cloud Scale which helps you to gather all the log files in one place, making them easier to access and use.

To deploy fluentbit

To save the fluentbit chart values to a file, execute the command:
helm show values fluentbit-<version>.tgz > fluentbit-values.yaml
To edit chart values to match your environment, execute the command:
vi fluentbit-values.yaml

To upgrade the fluentbit deployment, execute the command:

helm upgrade --install fluentbit fluentbit-<version>.tgz -f fluentbit-values.yaml -n netbackup

If using the OCI container registry directly, execute the command:

helm install --upgrade fluentbit oci://abcd.veritas.com:5000/helm-charts/fluentbit --version 1.2.3 -f fluentbit-values.yaml -n netbackup

Following is the output of the above command:

 helm show values fluentbit-11.0.tgz > fluentbit-values.yaml

 vi fluentbit-values.yaml

	helm upgrade --i fluentbit fluentbit-11.0.tgz -f fluentbit-values.yaml -n netbackup
