thank you seems it works, the same issue is with error counter. But this time is the rate, not percents. I think we could apply the same logic.

So maybe you can recommend the safe and realistic value to add in ifOutErrors_rate lt ?
Thank you

Hi
We have the same problem with Nexus 5K and 7.1(4)N1(1).
Is there any option to set up an alerts with a from.. and to.. values? Like if the value greather than 80% but lower than 100% send the alarm? In this case this percentage problem doesn't appear. Normally the alert just run if the percentage is over 80. Can we use an "AND" tag somehow?
Thanks

My Guess is that you are polling a Cisco Nexus which have a broken SNMP-stack, it sometimes reports crazy values for a couple of seconds. If you are not already running it, try uppgrade to nx-os 7.x Otherwise you can work around the problem by reconfigure you alert check with "delay 2" which will cause it to not send an alert unless the value is above the threshold for 2 polls in a row.

Hello,
What could be the reason of the generation of false alarm:
*ALERT*
Modify http://10.13.40.217/device/device=382/tab=alert/alert_entry=7751/
*Alert*
*MoreThan80PortUtilization*
*Entity*
*Ethernet1/51 http://10.13.40.217/device/device=382/tab=port/port=1694030/*
*Descr*
NXOS1-ITXx2
*Conditions*
ifOutOctets_perc ge 80 (395649)
*Metrics*
ifInOctets_perc = 11
- ifOutOctets_perc = 395649*
*Duration*
10m 8s (2017-11-08 02:18:10)
As you coud notice the *ifOutOctets_perc = 395649 * shows some irregular value, which's not on the graphs itself, but the alarm is generated.
During migration the migration period from old observium server to new one, at same time we have two observiums running, so older one have the same alerts configured - but that (older one) haven't generated any false alarm. So - waht could be the reason ?
Thanks!
