Master Trigger suggestion

[IT_Architect]

In the cockpit there is a Master Caution indicator. When it sets, the exact problem will be found on the on-screen display. I'm finishing an implementation that also uses IPMI, which returns not only values, but also a status. Status has the advantage of the manufacturer maintaining what normal operating ranges are, and the severity of the current condition. OK=0, NonCritical=1, CRitical=2, NonRecoverable=3. It would be useful to have one trigger watch many status items. When there is a problem, the Master Trigger would be set, and the exact problem could be determined from the latest data.

This is a lot like a question I asked a few days ago, I was looking for a way to have an item that is the count of active triggers at each level. Then you could define a master alarm as non zero count for disaster, high and average items (for example, whatever you need). The data is basically on the dashboard, but I don't see a way to trigger the master alarm.

I was thinking of tying one trigger to multiple items to avoid needing so many triggers. IPMI has status reporting for almost every item they support. OK=0, NonCritical=1, CRitical=2, NonRecoverable=3. If you wanted one for NonCritical, CRitical, and NonRecoverable, that would 60 triggers in a worst case scenario. If I could assign one trigger to multiple items, the worst case scenario would be 3 triggers, one for each of the error levels. Aside from IPMI, there are many checks that are simple set and reset checks. Often we have control over what gets returned, one way or another, thereby enabling us to adjust the return value to fit to our strategy.
