Cacti switch graphs do not appear

[Skywise]

I'm very new to both these forums and Cacti in general, and I'm hoping that I might find answers here.

We are running the following:

Cacti Version 0.8.7a
Cacti OS unix
SNMP Version net-snmp
RRDTool Version RRDTool 1.2.x

and trying to set up various graphs for a Foundry switch (NetIron MLX switch specifically) and having entered the host, all the graphs we create for it do not appear in the graph view interface. There are placeholders for them, but the graphs are not drawn.

Anybody have any clues?

Please let me know if more information is needed - as I indicated, I'm brand new to the Cacti tool.

Thanks in advance,

Usually means the device isn't responding to the SNMP equivelant of ping. You can test from the command line by:

Code: Select all

snmpwalk -v $yourversion -c $yourcommunity $fqdn_or_ip system

(In RedHat this is provided by net-snmp-utils).

Alternatively in the UI when you have this problem if you go to Devices it will show the device as down. You can also see how many eventcounts the device has been down and some other useful information.

Cacti -> console -> devices -> Select your device.

I'm very familiar with snmpwalk commands, and from the box that we have Cacti installed on, the walk command to the switch in question works with no problems.

Looking up the device in the UI the status shows as 'unknown' but in the detailed view of the device, it shows the SNMP information that it successfully polls from the box. Yet still none of the defined graphs for the host are drawn when we go to view the graphs.

Any other ideas would be greatly appreciated.

Unknown status means the device isn't up. Graphs/RRDs don't get created unless the device is up. Weird that it returns to your from a command line. Try boosting the timeout on the device?

If that doesn't help I suspect you'll need to look at the cacti.log with debug on to see what is up.

First, thanks for pointing me toward the cacti log file. Doing so lead me to discover that all the new hosts that we have added for at least a couple of weeks have the same graphing issue, for all types of graphs - none of them are showing up.

The Cacti log has many hundreds of entries that look like this:

10/29/2008 01:15:07 PM - SPINE: Poller[0] Host[43] DS[456] WARNING: Result from SCRIPT not valid. Partial Result: ...

but I'm unable to find any further information.

So there seems to be a problem with either the installation or the program, but I'm at a loss to determine what the problem might be.

Any additional ideas would be greatly appreciated!

Partial result appears, if you try to fetch data that isn't available for some reason. E.g. the target host may not support the specific OID you're asking for. See 2nd link of my sig
