[mrtg] Re: Monitor Solaris CPU from MRTG

[Brian Steele]

I want to add system and user stats together. Should I use & between the
2 OIDs like this:

1.3.6.1.4.1.42.3.13.1.0&1.3.6.1.4.1.42.3.13.3.0

Or do I need to collect them separate and use + like this:

1.3.6.1.4.1.42.3.13.1.0&1.3.6.1.4.1.42.3.13.1.0:public at 192.168.150.250 +
1.3.6.1.4.1.42.3.13.3.0&1.3.6.1.4.1.42.3.13.3.0:public at 192.168.150.250:

You need to add a .0 to the end.  I missed that you were using the 
walk command.  If you look at the response, snmpwalk is kindly filling

in the instance (.0), on to the end of your requested walk.

Try to run an snmpget with the OID and the instance number appended 
before modifying your conf file to verify this is the problem, but I'm
willing 
to bet that's exactly the issue.

Paul,

I've used the line you suggested:
Target[milesv_cpu]:
1.3.6.1.4.1.42.3.13.1&1.3.6.1.4.1.42.3.13.1:public at 192.168.150.250 

Now I get a different error:

SNMPGET Problem for 1.3.6.1.4.1.42.3.13.1 1.3.6.1.4.1.42.3.13.1 on
public at 192.168.150.250::::::v4only 
 at /usr/bin/mrtg line 1847
ERROR: Target[milesv_cpu][_IN_] ' $target->[8]{$mode} ' did not eval
into defined data
ERROR: Target[milesv_cpu][_OUT_] ' $target->[8]{$mode} ' did not eval
into defined data

What does v4only mean?

Brian

You must use TWO OIDs, not one, not three, but two.  They must be
joined

in the center with an ampersand, otherwise, the magical divination 
shall not work.

Try something like:

Target[milesv_cpu]:
.1.3.6.1.4.1.42.3.13.1&.1.3.6.1.4.1.42.3.13.1:public at 192.168.150.250: 


I can't remember if you need the leading dot in each OID or not...

I'm attempting to use MRTG to monitor CPU time on a Solaris 9 server. 
I
cannot figure out how to set up the Target line.  Snmpwalk works fine
with the specified OID.  Here is an example:
 

>snmpwalk -v 1 -c public 192.168.150.250 .1.3.6.1.4.1.42.3.13.1

SNMPv2-SMI::enterprises.42.3.13.1.0 = Counter32: 29628917

 

However, when I set the target line to: 

 

Target[milesv_cpu]: .1.3.6.1.4.1.42.3.13.1:public at 192.168.150.250: 

 

The result is:

 

0' instead of a numberpu][_IN_] '.1.3.6.1.4.1.42.3.13.
$target->[8]{$mode} ' evaluated to '*

0' instead of a numberpu][_OUT_] '.1.3.6.1.4.1.42.3.13.
$target->[8]{$mode} ' evaluated to '*

 

Why does one work and the other not?

 

Brian
