GigE interface graphs empty or missing data

Post by Justeco »

I'm new to Cacti so I may be doing something wrong.

I am gathering traffic data from two Cisco 3550 Layer 3 switches in my data center. All the graphs for my Fast Ethernet interfaces look great and were cake to set up (Thanks cacti guys!). However, the graphs for my GigE interfaces have been problematic from the start. I ussually get blank graphs with NaN being the value for everything. I spent last night playing with the graph types (64bit counter, or not, etc...) I have increased the max data values on the Data Sources to 1000000000000, but I don't think that is dong anything. I finally gave up last night about midnight, but when I came in this morning, the graph I was playing with actually did create data from about midnight to 8:30 this morning... Then it seemed to stop and leave a big hole in the data for the past few hours. New graphs that I have created on the other GigE interfaces since then are being created empty.

Am I doing something wrong, or is this the "missing data" issue I am reading a few posts about?

Thanks in advance,

Turn on debugging in cacti and look in the log file for that host. Is cacti still collecting any data?

What should I debug?

I'm not sure where you mean for me to turn on Debugging. In the data source debugging it shows me the rrdtool arguments (I guess you call them) and in the graphic debugging it says "rrdtool: OK".

So I took a look at the rra file, as I have before to try to figure this out, and it is being updated, but I'm not sure it is getting all the data it needs...

Code: Select all

filename = "3550_1_bdc_room_a_traffic_in_202.rrd"
rrd_version = "0001"
step = 300
last_update = 1126976702

Some log file data

Post by Justeco »

This may have something to do with it. My cacti.log is full of this:

Not sure why it would work for all the FE interfaces and not the ggE (well, it did for a while on one). I don't think I have any odd SNMP settings--JFFNMS used basically all the same support software and didn't have this issue. (I only say because I think it is an issue with cacti).

Solved!

Post by Justeco »

I was trying to use 64bit counters with snmpv1, which apparently doesn't work. Perhaps it shouldn't be an available option when using snmpv1 so that idiots like me don't try it?

Anyway...

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?
