dropping useless events

[neuronetv]

I've asked this question before but got no help so I'm trying again.
I use zm 1.25 on a centos 6 machine and it works great but it records hundreds of events containing just 1 alarm. These recordings are useless so I was hoping there might be a way to configure zm so it will only record/keep an event if it comprises 5 or more alarms. is there a way to do this?

I did read your other post and believe there is no direct way to set that as a value but you never know; there's some pretty resourceful folks here. You can try setting Overload Frame Ignore Count to some number so you can record persistent alarms that last longer then that and ignore those of a lesser duration. Should at least help.

ok thanks. Where is Overload Frame Ignore Count? I looked through the options but couldn't see a value named that.

It's in the zone settings.

Try this setting first probably exactly what you're looking for:

Alarm Frame Count
This option allows you to specify how many consecutive alarm frames must occur before an alarm event is generated. The usual, and default, value is 1 which implies that any alarm frame will cause or participate in an event. You can enter any value up to 16 here to eliminate bogus events caused perhaps by screen flickers or other transients. Values over 3 or 4 are unlikely to be useful however. Please note that if you have statistics recording enabled then currently statistics are not recorded for the first ‘Alarm Frame Count’-1 frames of an event. So if you set this value to 5 then the first 4 frames will be missing statistics whereas the more usual value of 1 will ensure that all alarm frames have statistics recorded.

ok thanks for that further help. I've set the Overload Frame Ignore Count to 4 so now it's wait and see how it goes.

edit 6/5/13: no it doesn't work, I'm still getting loads of 1 alarm events.
