Is it possible to calculate an item using other data items being pulled via snmp. I would really like to create an item to display "used memory" as opposed to the standard free,buffered,cached.
Via snmp I have memTotalReal, memBuffer, memCached, memAvailReal...so I would need to do something like:
memTotalReal - ([memBuffered]+[memCached]+[memAvailReal]) = Current Used Real Memory
Reason for this, is I would like to set a trigger to detect is the system is running out of memory. If there is a better way of accomplishing the same task via snmp, I will gladly entertain other suggestions!!
