[mrtg] Target not evaluating to number

[MMartin at jwpepper.com]

Sorry its been a while since I've touched my MRTG config stuff since I 
configured it originally.

But I think the Target line should look like this:

SNMP v1:
        Target[192.168.1.1]: 1.3.6.1.2.1.25.2.3.1.5.40&
1.3.6.1.2.1.25.2.3.1.6.40:public at 192.168.1.1:

SNMP v2:
        Target[192.168.1.1]: 1.3.6.1.2.1.25.2.3.1.5.40&
1.3.6.1.2.1.25.2.3.1.6.40:public at 192.168.1.1:::::2
                |---> Don't forget the 5 ":" at the end of the line and 
the "2" for SNMP version 2 if that's what your using


Let me know if that works..?

Thanks,
Matt

I am trying to collect data for disk space usage using the following:

####
#### Disk Usage
####                                                                       
                                                                
Target[localhost.du]: 1.3.6.1.2.1.25.2.3.1.5.40&1.3.6.1.2.1.25.2.3.1.6.40 
                                    Title[localhost.du]:   Used disk space 
                                                                          
            MaxBytes[localhost.du]: 4209180                               
                                                              
PageTop[localhost.du]: <H1> Used disk space </H1>                         
                                      LegendI[localhost.du]:  Disk Space 
Available                                                                 
            LegendO[localhost.du]:  Used Disk Space                       
                                                          
Legend1[localhost.du]:  Disk Space Available                               
                                            Legend2[localhost.du]:  Used 
Disk Space                                                                 
                YLegend[localhost.du]:                                     
                                                                      
kilo[localhost.du]: 1024                                                   
                                                        kMG[localhost.du]: 
,,k,M,G,T,P             



I get the following result:

2013-09-19 22:42:45: ERROR: Target[localhost.du][_IN_] 
'1.3.6.1.2.1.25.2.3.1.5.40&1.3.6.1.2.1.25.2.3.1.6.40' evaluated to '(' 
instead of a number
2013-09-19 22:42:45: ERROR: Target[localhost.du][_OUT_] 
'1.3.6.1.2.1.25.2.3.1.5.40&1.3.6.1.2.1.25.2.3.1.6.40' evaluated to '(' 
instead of a number


If I use SNMP from the CLI I get:

prompt% snmpget -v2c -c public localhost 1.3.6.1.2.1.25.2.3.1.5.40
HOST-RESOURCES-MIB::hrStorageSize.40 = INTEGER: 4664409


Where is the '(' coming from as mentioned in the error message ?  Why am I 
getting that instead of the integer that is its value ? 



cheers,
