How can this happening? I've the SNMP results OK, but in my graphs there are only -1 values. If I use a different OID it will draw the value right, but not with the ones I want (memory).

HELP please! I've spend 2 days and I cannot guess what's wrong!

THANKS a LOT

Please, any ideas? I'm still in this problem. I'm able to monitor all MIBs except memory ones. I've tried to remove MIBs of NET-SNMP, put them up again...

Thanks!

Sillly question, what is the max on the data source template? Try setting it to 0 and delete the affect rrd's so they are recreated.

Also, check that you have a reasonable max on the graph template as well.

OK Tony, I already adjusted the max values, but I didn't know that a rrd file deletion was needed... so thank you again for your time to answer us.
