Data Query [SNMP -Get Processor Information]

[leeeroybrown]

Hi,

I am really wrestling with this app, I hope you'll see i am giving it an honest effort before coming to you for help.

This is a brand spanking new install of cacti plus all of the patches. I am adding the first device, which I only want to poll the CPU Utilization via SNMP Data Query. In the Assoc.Data Query box I have added the query from the dropdown. But I can't create any graphs from it My results are:
1.) SNMP - Get Processor Information (Verbose Query) Uptime Goes Backwards Success [0 Items, 0 Rows]

Did I miss a step ??? I am just following the instructions from the manual.

BT----- I am using the cmd.poller in my setup.

When you are viewing the device, do you get an SNMP error at the top?

Also, what type of device is it?

Hi,

No SNMP Error, I get a snmp report looks a bit like this...
SNMP Information
System:00:LINUX:PROD-DB:2.4.21-27.ELSMP:#1:SMP:WED:DEC:01:21:59:02:ESTI686
Uptime: 596891893
Hostname: prod-db

This is an IBM Blade Server. Here is what comes out of the DataQuery debug screen.

Your host needs to support the "host" table for this query to work. Try snmpwalking 1.3.6.1.2.1.25.3.3 to find out if it does.

net-snmp does not include this table by default, I believe, but you can include it at compile-time.

FYI,

Hi,

I am not exactly sure what this response means. Is my host the cacti box or the boxes getting monitored ? The "host table" is this a system file or part of the snmp build?? Here is the configure line for net-snmp compile:
./configure --prefix=/usr --with-mibdirs=/usr/share/snmp/mibs --with-mib-modules="host disman/event-mib smux" --with-sysconfdir="/etc/net-snmp" --enable-shared

Can you tell from that, theres the host module listed. Does that help?

Thx-

He meant, that the remote host must have some option enabled that is kown as the HOST MIB. Not all snmp enabled deviced support this. Try the query, dgamble asked for to verify, that your remote host responds to queries of HOST MIB OIDs.

Yes, that's the compile option that needs to be there- the "host" in --with-mib-modules="host disman/event-mib smux". BUT, this option needs to be compiled in on the REMOTE host side, yes.

So again, check to see if the remote host supports these objects.

What OS is the remote host?

Don't worry about mibs at this point, the remote host does not support HOSTMIB, which means, there is a configuration error on the remote host.
