The Alert checker sends messages if pooled get null for a port parameters
Hello Community, Was there anyone who had an issue and could give me advice on how to work around my case described in the attached file ?
Briefly: I set an alert checker, it checks the port state "ifOperStatus equals down" wait delay time and sends me the message. The port's operational status is constantly down for a long time.
Sometimes the checker get NULL for port parameters so as ifOperStatus is NULL the checker defines it is not equals to "down" and sends me "false" message "Clear"
The next check time the checker gets real state ifOperStatus equals down and as Alert was cleared last time so checker creates a new alert and sends me notification.
Every time the checker gets null I am getting Clear then Alert notification. If I could operate with the previous state at the checker condition rule I would be set to create an alert only if the previous state was "up" AND the state for now is "down". [image: image.png]
This is because sometimes devices don’t respond correctly and we have blank data.
You can alert on “ifOperStatus not up”, this won’t trigger on transitory blank values.
