 |
|
I'm trying to get temp data from a temp probe. I can get the data- the log file shows that the correct output is retrieved:
08/23/2008 12:05:05 PM - CMDPHP: Poller[0] Host[31] DS[438] SNMP: v1: 192.168.0.38, dsname: temp_back_c, oid: .1.3.6.1.4.1.20916.1.7.1.2.1.2.0, output: 10117
the graph is set to divide by 100. But why is it never graphing anything?
I can attach the graph template if needed.

I would first check the max value (if any) of the datasource:
the "Maximum Value" field in the associated data template.

| Ok, it was like 600 and in the incoming is clearly higher. I set it to 20,000 and will see how it goes today.

Ok, still nuthin. the data is clearly being gotten as the log shows. I've attached the graph and data templates and details from one of the graph template items.
Any other ideas?

Did you rrdtool tune the rrd file?

This applies the change of the data template the existing files. Please be aware of the fact, that changing a data template does NOT affect any exting rrd file

| did that on the two rrds and still no graphing. I'm going through your tutorials right now on recreating these. The biggest question I have is on the OID- the one I got from the manufacturer is quite long compared to the ones in your examples.
