9.1. Possible Issues #
9.1.1. Database Instance Log Access Errors #
Symptoms:
Instance log data is not being collected.
The following error messages are displayed in the collector log:
{ "level": "error", "ts": 1733457921.250963, "msg": "Failed to open file", "kind": "receiver", "name": "filelog", "data_type": "logs", "component": "fileconsumer", "error": "open /var/log/postgresql/postgresql-2024-12-06.csv: permission denied" }
Root cause: The filelog
receiver cannot read the logs specified in its configuration.
Solution: Configure file access permissions and set an appropriate value for log_file_mode
in the database instance configuration so that new log files are created with the required permissions.
