Alert logs

Collect export alert logs with a log ingestion tool.

The exporter exports alert log records as a JSON file suitable for collection by a log ingestion tool like Promtail or FluentBit.

Each exported log record includes the source database name:

{
  "timestamp": "2026-03-13T18:37:46.302Z",
  "database": "db2",
  "moduleId": "",
  "ecid": "",
  "message": "Example alert log message"
}

Alert logging is configured with the following parameters in the exporter config file:

Parameter	Description	Default
log.destination	Base alert log file path	/log/alert.log
log.interval	Interval to log records	15s
log.disable	Disable logging if set to 1	0
log.perDatabaseFiles	When true, write one file per database using the pattern alert-<db>.log	false

Example alert log YAML configuration:

log:
  # Path of log file
  destination: /opt/exporter/alert.log
  # Interval of log updates
  interval: 15s
  # Optional: write /opt/exporter/alert-<db>.log instead of a shared file
  perDatabaseFiles: true
  ## Set disable to 1 to disable logging
  # disable: 0

Multiple Databases and Alert Log export

If the exporter is configured to scrape multiple databases, it is recommended to set the logging.perDatabaseFiles property to true, creating a separate log file for each database.

When perDatabaseFiles is enabled and destination is /opt/exporter/alert.log, a database named db2 writes to /opt/exporter/alert-db2.log.
