SPINE Problem with Interface - Traffic

Post by Darkall »

Hello,

I am not sure where to go with this, am seeking advice on where to look next. The solution is probably really simple.

I am wanting to switch poller processes from cmd.php to spine, due to the number of devices / rrd's I am working with (~2 minutes currently for cmd.php, expecting this to grow significantly in the near future). I compiled the svn 5/31/08 version of spine for my cacti 0.8.7b. I had no previous version of spine. When I change from cmd.php to spine, the polling process time was reduced to ~35 seconds, however there were a large number of "WARNING: Result from SNMP not valid. Partial Result: ..." messages. While looking at this, the problem appears to be with "Interface - Traffic". It almost seems like spine is unable to query my devices specifically for interface traffic data. Everything else appears to poll and graphs correctly, I just get no data on my interfaces (any device interface; router / computer / switch / et cetera).

I checked my data templates Interface - Traffic for duplicate traffic_in / traffic_out, no luck.

I have made no special modifications to Cacti. It's all base software with plugin arch and a few plugins.

Any suggestions on what or where to look now?

Switching back to cmd.php, everything appears normal again.


Thanks,
Dark

Um...

What version of NET-SNMP libs and headers do you have installed?

NET-SNMP version: 5.3.1


I'm tempted to gather and post full spec's on the environment, but I'm afraid of information overload; post too much data and it would require too much effort to troubleshoot. I don't think the problem is with the common Cacti environment, but instead something stupid I continue to overlook.

Any thoughts are appreciated.

A little more data

Trying to keep information relevant.

This is debug logging for a single host and subsequent snmpwalk for the OIDs in question;

The "WARNING: Result from SNMP not valid. Partial Result: ..." occurs with every host I am polling "Interface - Traffic" for, which is every host I have in Cacti.


Again, any thoughts or suggestions are appreciated, especially any suggestions on other areas to debug or log.


Thanks,

I am also hitting the same issue.
I am running on RHEL 5.1, Net-SNMP 5.3.1. Spine is compiled from todays SVN sources (I was hitting this bug and it would just crash http://bugs.cacti.net/view.php?id=1183).
Switching to cmd.php restores the graphs.

I did packet captures and the results returned when doing a manual snmpget and a get that is done by spine are the same. For some spine does not want to accept them.

Me too. :(

If I swap to cmd.php, the graph can be updated. but if install the spine and swap to it. then no updated graphs anymore..

Here are the details

When I ran debug mode. I got this message:

What does the Value: U mean?

I'm also working on a migration for a little 32 bit box to a beefy 64bit box and with the latest svn spine I also am running into what seems like my graphs are not updating. All values are either U or 0.

Code: Select all

U means "unknown"/"Invalid"
