• CPU usage is high for a sustained period

  CPU idle is 2% or less for a sustained period. The system cancels the alarm when CPU idle increases to 7% or more for a sustained period. Ignore this alarm unless it persists for more than ten minutes. Conditions that can trigger this alarm are:

  • The overnight Database purge.
  • System service startup.
  • System upgrade or rollback.
  • Abnormal system behavior.
• Disk space is critical (main/data)

  Occupied disk space has reached 95% or more for a sustained period. The system cancels the alarm when disk space drops to 92% or less for a sustained period.  The alarm description may also include (main) or (data). Una fuente común de documentos compartidos por la

  • (main) indicates that the root disk partition is running out of space.
  • (data) indicates that the /var disk partition is running out of space.
• Disk space is low (main/data)

  Occupied disk space has reached 85% or more for a sustained period. The system cancels the alarm when disk space drops to 82% or less for a sustained period.  The alarm description may also include (main) or (data).

  • (main) indicates that the root disk partition is running out of space.
  • (data) indicates that the /var disk partition is running out of space. The most likely reason for low disk space is a very large number of messages held in message areas.
