Information
Stackdriver-logging agent or fluent-bit logging agent needs to be activated in order to export logs to Cloud Logging.
Rationale:
If neither stackdriver-logging nor fluent-bit service is running, the logs will not be exported to Cloud Logging.
Solution
Stackdriver-logging Agent
Run the following command to enable stackdriver-logging :
# systemctl start stackdriver-logging
Fluent-bit Logging
Run the following command to enable fluent-bit :
# systemctl start fluent-bit
Works for Both
Simply update the instance metadata to enable logging as follows:
# gcloud compute instances add-metadata <instance-name>
--zone <compute-zone>
--metadata google-logging-enabled=true
