Hello,
I am trying to monitor using MRTG total memory and used memory .. however we only have OIDs for used and free memory.
so my target is as follows
Target[test]:1.3.6.1.4.1.9.9.48.1.1.1.5.1&1.3.6.1.4.1.9.9.48.1.1.1.6.1:public at router_ip
I would like to have the IN parameter as the sum of 2 while keeping the second as is, ie something like
Target[test]:(1.3.6.1.4.1.9.9.48.1.1.1.5.1 + 1.3.6.1.4.1.9.9.48.1.1.1.6.1)&1.3.6.1.4.1.9.9.48.1.1.1.6.1:public at router_ip
from what i read it seems we can only sum in and out values ie
Target[test]:1.3.6.1.4.1.9.9.48.1.1.1.5.1&1.3.6.1.4.1.9.9.48.1.1.1.6.1:public at router_ip + 1.3.6.1.4.1.9.9.48.1.1.1.6.1&1.3.6.1.4.1.9.9.48.1.1.1.6.1:public at router_ip
this will eventually give us total memory as IN and 2x used memory as OUT
any ideas ??
Thanks
Nabil
