MSSQL transaction_log metricset

MSSQL transaction_log metricsetedit

transaction_log Metricset fetches information about the operation and transaction log of each MSSQL database in the monitored instance. All data is extracted from the Database Dynamic Management Views

  • space_usage.since_last_backup.bytes: The amount of space used since the last log backup in bytes
  • space_usage.total.bytes: The size of the log in bytes
  • space_usage.used.bytes: The occupied size of the log in bytes
  • space_usage.used.pct: A percentage of the occupied size of the log as a percent of the total log size
  • stats.active_size.bytes: Total active transaction log size in bytes
  • stats.backup_time: Last transaction log backup time.
  • stats.recovery_size.bytes: Log size in bytes since log recovery log sequence number (LSN).
  • stats.since_last_checkpoint.bytes: Log size in bytes since last checkpoint log sequence number (LSN).
  • stats.total_size.bytes: Total transaction log size in bytes.

This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
