Using alarms to collect and monitor device status
Beginning in Brocade NetIron R05.3.00, the software keeps two logs; one of hardware status
currently available to the system, and another of hardware status history. The current alarm log
keeps only entries for current information; when a hardware status is no longer valid, the entry is
cleared. The alarm history log keeps a record of hardware statuses even after the status has
changed. The alarm history log enables you to quickly determine trouble areas in a system. For
example, by accessing the history, you can quickly determine if a problem is occurring too
frequently and might require action.
Each hardware status entry is called an alarm and is classified by severity assigned by the
software. The software categorizes alarms in the following levels:
TABLE 38 CLI display of SFM link information
