Hello,
I have read the man pages and it seems that the monitor statement only
accepts one expression. I would love to find out if there is any way to do
AND/OR logic in the monitor statement.
Challenge: Linux system has multiple interfaces; however, only a few are
both admin and operationally up. The rest are both admin and operationally
down.
Current solution: The standard link monitoring statements work off of the
ifOperStatus. For example, the following lines will generate linkDownTraps
when the ifOperStatus is detected to be down (2):
notificationEvent linkUpTrap linkUp ifIndex ifAdminStatus ifOperStatus
ifName ifDescr
notificationEvent linkDownTrap linkDown ifIndex ifAdminStatus
ifOperStatus ifName ifDescr
monitor -u snmpdTrapUser -t -r 30 -e linkUpTrap "Generate linkUp"
ifOperStatus != 2
monitor -u snmpdTrapUser -t -r 30 -e linkDownTrap "Generate linkDown"
ifOperStatus == 2
Since, some of my interfaces will be both admin and operationally down, I
only want to generate linkDownTraps IFF the interface is ifAdminStatus ==
UP AND ifOperStatus == DOWN.
Question: Is it possible to do something like the following:
monitor -u snmpdTrapUser -t -r 30 -e linkDownTrap "Generate linkDown"
ifAdminStatus != 2 and ifOperStatus == 2
I know that the monitor statement does not support AND logic, but I am
looking for any ideas on how to do this.
thanks,
Manjul
