<div style="font-family: Arial; color: rgb(0, 0, 0); font-size: 12pt;">And here I thought I was done. When using the default output from the cfgmaker with that template, it uses a multiplication method as below:<br>
<br>
# Filesystem C:\ Label: Serial Number 3a8c3a33<br>
Target[192.168.10.75.disk.C]: 1.3.6.1.2.1.25.2.3.1.6.2&1.3.6.1.2.1.25.2.3.1.6.2:public@192.168.10.75 * 4096<br>
<br>
&&<br>
<br>
# Memory used<br>
Target[192.168.10.75-memory]: 1.3.6.1.2.1.25.2.3.1.6.14&1.3.6.1.2.1.25.2.3.1.5.14:public@192.168.10.75 * 65536<br>
<br>
2009-09-25 22:00:23: ERROR: Target[desktoppc.mem][_IN_] ' $target->[50]{$mode} * 65536' (warn): Use of uninitialized value in multiplication (*) at (eval 96) line 1.<br>

<br>
So, how do I fix the multiplier issue? The desktoppc.mem is currently showing 128KB used memory.....it has 8GB in there and I have Vista Ultimate 64-bit, anyone notice an issue there?<br>

<div style="font-family: Arial; color: rgb(0, 0, 0); font-size: 12pt;">Using the generic template as suggested, I managed to get CPU going on a quad core. Still trying to find a better way to display it so I can see each individual core on one graph, but that's
out there on the mailing list now as well. Thank you very much, I think that template may solve the issue I've been having trying to get load values populating in a graph.<br>

<div dir="ltr"><font color="#000000" face="Tahoma" size="2">I'd really suggest using cfgmaker templates to generate the various Targets. This way you will get all-numerical OIDs (so no problems with unrecognised short symbolic names) and also the host cfgmaker
template in the website probes for th existance of the various OIDs before creating the Target definition, so you wont get one that doesnt exist.</font></div>
<div dir="ltr"><font face="tahoma" size="2"></font> </div>
<div dir="ltr"><font face="tahoma" size="2">The cfgmaker documentation tells you the details, but basically you just use
</font></div>
<div dir="ltr"><font face="tahoma" size="2"> </font><font face="tahoma" size="2">cfgmaker --host-template=template.htp
<a href="mailto:community@hostname" target="_blank">community@hostname</a></font></div>
<div dir="ltr"><font face="tahoma" size="2">if your monitored host is 'hostname' with snmp community 'community' and the host template is called 'template.htp'. An interface template is similar, except that it is run once PER DETECTED INTERFACE rather than
just once.</font></div>
<div dir="ltr"><font face="tahoma" size="2"></font> </div>
<div dir="ltr"><font face="tahoma" size="2">Note that there are some problems with using SNMP -</font></div>
<div dir="ltr"><font face="tahoma" size="2">1. You need to make sure it is enabled</font></div>
<div dir="ltr"><font face="tahoma" size="2">2. You need to make sure the apporpriate sections are enabled - eg with Linux you need to have the appropriate lines in the /etc/snmp/snmpd.conf to enable disk space checks, load average checks, and so on</font></div>
<div dir="ltr"><font face="tahoma" size="2">3. Different OSs support different parts of the OID tree. For example, Windows and Linux give different places for data, and so do Solaris, Cisco and so on. Plus different vendors have vendor-specific extensions
which may or may not be useful.</font></div>
<div dir="ltr"><font face="tahoma" size="2">4. You need to set up your permissions correctly to allow the monitoring server rights to view the OID tree correctly</font></div>
<div dir="ltr"><font face="tahoma" size="2">5. With Windows in particular, the Storage mappings can be re-enumerated on the fly if you plug in or remove USB devices. This can mess up storage graphs done via SNMP. You may be better off with something the like
mrtg-storage check plugin which uses SNMP but confirms the table has not been re-enumerated.</font></div>
<div dir="ltr"><font face="tahoma" size="2"></font> </div>
<div dir="ltr"><font face="tahoma" size="2">If you run with the all-hosts host template from
<a href="http://www.steveshipway.org/cfgmaker" target="_blank">www.steveshipway.org/cfgmaker</a> and it doesnt generate any Targets then check your SNMP configuration.</font></div>

<div style="font-family: Arial; color: rgb(0, 0, 0); font-size: 12pt;">I'm having some issues with monitoring the CPU and RAM of a Phenom machine running Vista. I'd like to watch all 4 cores. I'm sure it's a problem with OID. But don't know what to switch to.
This is what I get in my logs:<br>
<br>
SNMP Error:<br>
Received SNMP response with error code<br>
error status: noSuchName<br>
