disappearing SNMP data [solved]

Post by kirigoe »

hi,

I'm monitoring a UPS through the server it's connected to for input and output voltages, this works great. However when I try to fetch the battery voltage, all I get is "nan" on the graphs and nothing else. The setup for the battery voltage is exactly the same as for the other voltages, using a "Get SNMP Data". I can fetch the SNMP OID from a php script on the same host as cacti is running on without problem, and they values are all integers, the only difference being that the battery voltage is about 10 times as big a number than the other numbers.

Is there a way I can control what is actually fetched through SNMP so I can find out why the value isn't showing up? It seems I've ruled out most error sources by now.

I'm running cacti 0.8.6b on PHP 4.3.6 and MySQL 4.0.20 on a Gentoo Linux server.

thanks in advance,
Daniel

Run one time in debug mode and post your Logfile. Also, verify that the OID is actually valid using a tool like Getif or Net-SNMP from the command line.

I can get the value from an snmpget on the commandline and from PHP scripts, and as the debug log shows, the value is clearly fetched (the specific value is in bold, search for "cflnas4_powerware_v_battery_91.rrd"):

If it is actually 10x what it should be, create a CDEF that divides by 10 and then display your data using the CDEF.

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?

no that's not the problem, the thing is that the value doesn't show up at all on the graphs, not on the graph with the other voltages or on a graph with only this value, it says "nan" in the graphs. the settings are as far as I can see exactly like the other values with the sole difference that the value is about 10 times as high, but still I should see it in the graphs right?

You should dump the RRD file from the command line and inspect it's contents. Goto www.rrdtool.org and read the manual. That way you should at least know if the data is being captured.

I found the problem, I never adjusted the "maximum value" for the data template, thus it was still on 300 and the values fetched wouldn't fit there. thanks for your input.
