I have 10 VMWare Linux RHEL 6.5 nodes running .. one running cacti, and the other 9 being monitored.

Somehow the graphs all seem to be providing the same stats for all the machines (ie: if I look at Load Average for node1, and Load Average for node2,3,4,... they all show exactly the same stats, very low usage in the 0.01 range, with the same sized spikes and valleys at the same times ... similar results are seen with the other graphs.)

I have the following graphs configured:
Linux - Memory Usage , Unix - Load Average, Unix - Logged in Users, Unix - Processes.

When I do a snmpwalk command for each node I see the unique information from snmpd.conf, so it seems to be looking at different nodes.

Not sure if I installed properly? Maybe I need to do more on the monitored nodes?

I installed cacti on one node, went to the other 'monitored' nodes and installed snmp (yum install net-snmp net-snmp-libs net-snmp-utils) then added the devices in cacti and created the graphs.

Did I miss some steps?

Thanks

cacti v 0.8.8b

If cacti runs, I would not suspect that.

If snmp works, you don't.

And are the graphs associated with these hosts?

Hard to say with this info. Do you have datasources for all these hosts?

Common mistake - you probably used 'Local Linux Machine' as the template, which collects data from the server Cacti is installed on. So you have a bunch of the same graph...

You should use the Net-SNMP Device template, or Percona's Linux templates

Please be aware that if you are using Percona's scripts, you may have to patch them as there is a bug when an empty string is passed it in the later versions of cacti, it changes the parameter type and causes some issues. I have an outstanding patch with them on their GitHub repo.
