Monitor CPU on the AIX 5.1

[wimonchai]

Hi,

I'm using cacti 0.8.6c for a while.I can monitor the windows2000,2003 very well.My problems are I can't monitor AIX 5.1 Servers.I got only used space file system and network traffic but no CPU,Memory,Process,Login User...=( How can I do? Please suggest me..Thank you...

please issue the following from your command line:

snmpwalk -c <your_community> -v 1 aix_host_name .1.3.6.1.2.1.25.3.3.1

Please post output.

Hi,

Here is the output from AIX5.1

snmpwalk -c xxx -v 1 172.20.x.x .1.3.6.1.2.1.25.3.3.1

HOST-RESOURCES-MIB::hrProcessorFrwID.1 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.2 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.3 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.4 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorLoad.1 = INTEGER: -2147483648
HOST-RESOURCES-MIB::hrProcessorLoad.2 = INTEGER: -2147483648
HOST-RESOURCES-MIB::hrProcessorLoad.3 = INTEGER: -2147483648
HOST-RESOURCES-MIB::hrProcessorLoad.4 = INTEGER: -2147483648


I try to use this command on the other Windows Server ,the results are

snmpwalk -c yyy -v 1 172.20.y.y .1.3.6.1.2.1.25.3.3.1
HOST-RESOURCES-MIB::hrProcessorFrwID.1 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.2 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorLoad.1 = INTEGER: 14
HOST-RESOURCES-MIB::hrProcessorLoad.2 = INTEGER: 16

Because AIX's snmp answered the -2147483648 value (not 0-100 value)

I can't monitor them.

How can I go next??

Thank you.

Please check with IBM and see if they have a patch. They must be having a confusion between signed and unsigned integers causing the issue. This would be a type mismatch. I would rather see IBM fix their problem.

What oslevel are you at on that AIX box?

Also, is it 64 or 32 bit kernel?

[wimonchai]

We are running 32 bit mode.

[rony]

Make sure you have all the sub agents running. Specifically, you need hostmibd and aixmibd. Check your /etc/rc.tcpip, make sure that snmpd, hostmibd and aixmibd are in startup. Also, if you restart the deamons, you must start snmpd first.

[wimonchai]

Thank you Tony..

I have snmpd and hostmibd running..but no aixmibd. I'm finding the way to find and install aixmibd. I will post again when I'll have gotten it. =)

[rony]

It might be part of the Performance Toolkit, I don't recall. But I kinda expect it to be in bos.tcp.client or mabye bos.tcp.server. Don't remember for sure.

[wimonchai]

Alright now I fixed the problems. It's about AIX 5.1 bugs that return the wrong values of the ProcessorLoad.

I applied patch fix from IBM and it's work.

I updated bos.net.tcp.client.5.1.0.60 and bos.up.5.1.0.58 and restart snmpd and hostmibd. Just's it.

Hope these will help others.

Thank you for all yr helps, everyone! =)

Hi there,

Are you using net-snmp on AIX, or are you using the built-in snmp? What graph template are you using for your CPU graph?

I've had cacti running very nicely with Solaris and net-snmp, but I've been having trouble getting it to work as good on AIX. Any tips?

[rony]

I created a AIX Template for the builtin SNMP agent for AIX. You will find it in the Scripts and Addons section of these forums.

We both are using the builtin AIX SNMP agent.

[chadw]

Thanks,

I just found that after I posted my orginal question.

I've got the MIB tree enabled and the template and xml files installed. I'm now getting lots of filesystem graphs, load average, network stats. I still can't get processes, processor usage, or memory stats. Has anything been developed for that?

[rony]

In 5.2 and 5.1 those metrics are not supported by the IBM agent. I'm not sure about 5.3. But I did work with IBM for over a week on this issue and talked to the developers on it. I endded up putting in a "Marketing" request, or otherwise known as a feature request to make it work properly.

You can attempt to compile and use NET-SNMP and see if that get's you the metrics you are looking for.

Guys,

Anyone can package up net-snmp for AIX 5.2 ?? I don't have GCC or GNU utilities installed on my AIX, so I cannot compile. I found net-snmp for AIX 5.2 on the net but it core dumps every time I try start the service (yes, I did install using mkssys utility)

Thanks!
