Hi,

How do keep track of the number of shelved alarm? I know len(system.alarm.queryStatus(state=[“ActiveUnacked”])) can be used to count the number of alarms based on state, but I don’t know the argument for shelved alarms. I tried “ShelvedUnacked”, but that is not correct.

Thanks,  
Ali

It is a different call for shelved alarms.

I forgot about that function and went about it a different (probably non-performant) way:

```auto
    all_alarms = system.alarm.queryStatus(includeShelved=True)
	non_shelved = system.alarm.queryStatus(includeShelved=False)
	shelved_count = len(all_alarms) - len(non_shelved)

```

</div>

The logic looks pretty straight forward, but the count is off. I triggered 2 alarms and shelved one, but when I ran the script, it showed 3 shelved alarms.

I didn’t follow the example in the documentation. Could you please help me with the syntax to get a count of shelved alarms only?

This logic counts ALL alarms, not just active alarms, so it sounds like you have two other alarms which are not active or shelved...

This might be better:

```auto
    # modify all_states to suit your needs
    all_states = ["ClearUnacked", "ClearAcked", "ActiveUnacked", "ActiveAcked"]
    all_alarms = system.alarm.queryStatus(state=all_states, includeShelved=True)
	non_shelved = system.alarm.queryStatus(state=all_states, includeShelved=False)
	shelved_count = len(all_alarms) - len(non_shelved)

```

count\_of\_shelved\_alarms = len(system.alarm.getShelvedPaths())

Thank you. This worked out perfectly.
