Event and Availability Management
Alarm management denotes systematic handling of alarms to safeguard modern data centers. An alarm is defined as an event that requires system administrators to respond fast and target-oriented.
Two types of alarm management can be distinguished.
In a control center, incoming alarms are displayed on a monitor overview informing about occurring events, while an on-call service solution is used for external alarms.
Why is a target-oriented alarm management required?
Events may cause a flood of alarms in the control center, i.e. one event may cause many subsequent alarms:
- Irrelevant alarms that only show a status change and are no alarms in the strict sense
- Unnecessary alarms which the operator merely acknowledges without knowing what to do with them. They are called nuisance alarms.
This desensitizes operators so that important alarms might be ignored which may lead even to considerable malfunctions of the IT operation.
Therefore, the crucial point of state-of-the-art and reliable alarm management is to reliably recognize events that need to be reported and to inform the responsible persons, which must be secured by escalation steps.
Alarm Management with the ZIS System – as few alarms as possible, but as many as required
In the ZIS System, alarm information is carefully processed by upstream situation analysis, event correlation, filters, and prioritization. It is only then that alarm paths are started, that can easily be defined with individual escalation steps and acknowledging options. All common alarm media, such as SMS, voice call, E-Mail, text-to-speech and fax, can be combined in any way. Comprehensive logging and display options, broad-band interfaces such as the SMS large account, and an integrated scripting language complete the powerful alarm management of the ZIS System.
