hello! I have been playing with MRTG again recently and started monitoring memory usage via SNMP against my debian/redhat/suse machines here.
Only problem is, from what I can tell, the redhat box does not report anything for memory usage, all variables report a value of -1. At first I thought maybe it was a kernel thing(my debian boxes run 2.2.19), but the SuSE 8 system runs 2.4.18 same as redhat 7.3, and they are running the same snmp config file(which is empty[1]). Some other variables such as # of processes on the system work but for some reason the memory ones do not!

I don't understand why these other systems respond with the data and redhat returns -1 for everything up2date shows my system running the latest available versions of all the packages.. thanks nate [1] yes I am aware that this is a big security risk. my reading of some docs says that by loading an empty config everything will be available as read only variables with a community string of public. since my home network is protected by 2 firewalls and a NIDS I am not very concerned about security on this snmpd at the moment. get it working first, secure it later. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@;redhat.com?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
