Alert on memory summary (Memory pool confusion)

Help
1

Hello

I want to create an alarm for any memory over 80%.

so i created an alert rule for %mempools.mempool_perc >= “80”

However it keeps alarming on some Cisco routers because i have memory pools which show 100% constant. I’m not sure what these are, but i’m only interested in the memory summary. For example if i login to this box and run a “show memory summary” i only see 60%. Can anyone shed some light?

Edit those values in the device settings and set them to 101 percent warn.

Thanks for the workaround Kevin,

I just found out this is only for Cisco IOS-XR devices, the normal Cisco IOS don’t report the “Image” and “Reserved” memory pool which always seem to be 100%. Ideally i wouldn’t have to go round all the IOS-XR devices and turn these memory pools to 101%.

I wonder if there is a way I can remove these memory pools globally, like the way we do with certain interfaces , e.g
$config[‘bad_if’][] = ’ or $config[‘bad_if_regexp’][]

Do you think this is possible?

Thanks

I don’t think that would work with memory. That’s only for interfaces.
