RRD file is updated, however graph is blank

techie411 · Post by **techie411** » Tue Jul 18, 2006 8:05 pm

Is anyone else experiencing an issue where RRD file is updated because the current time is there after running the poller, however the graph is blank. Like there's no values in the actual rrd file. This is specifically for an Interface graph. Any assistance appreciated. Thanks.

Here's the debug for the graph:

I saw the following in the logs:

07/18/2006 04:00:06 PM - CMDPHP: Poller[0] Host[22] DS[192] SNMP: v2: server1.host.com, dsname: traffic_out, oid: .1.3.
6.1.2.1.31.1.1.1.10.2, output: U

So I ran snmpwalk against the OID:

snmpwalk -c public -v 1 localhost .1.3.6.1.2.1.31.1.1.1.10.2

And nothing came up. How do I change the OID? In the datasources??

try the same with v2c? Also check your timeout, although I don't think that is it. I guess what I am saying is that the devices likely does not support v2c.

snmpwalk -c public -v2c localhost .1.3.6.1.2.1.31.1.1.1.10.2
IF-MIB::ifHCOutOctets.2 = No Such Object available on this agent at this OID

However, if I put in another OID, it goes.....

snmpwalk -c public -v2c localhost .1.3.6.1.2.1.2.2.1.16.2
IF-MIB::ifOutOctets.2 = Counter32: 55056975465323

So what do I need to modify?? Is Cacti using the wrong OID?

You have selected a 64-bit counter graph. It would appear as though your host does not support 64-bit counters. Please create a graph using the "bit/sec" instead. Cacti is NOT using the wrong OID, you are, by the by.

I see.....I changed to 64 bit counters because "bit/sec" wasn't working also. I changed back to "bit/sec" & graph is still empty. What else can I do to troubleshoot this issue? Thank you for your help!

Hmm, with the new graphs created, please turn logging to medium and run 1 poller pass. Post the results. Also, within the host, perform a verbose requery of the device and post that.

How do I run one poller pass? Is this it??

07/19/2006 10:30:06 AM - CMDPHP: Poller[0] Host[22] DS[193] SNMP: v2: server.domain.com, dsname: traffic_in, oid: .1.3.6.1.2.1.2.2.1.10.2, output: 0

07/19/2006 10:30:06 AM - CMDPHP: Poller[0] Host[22] DS[193] SNMP: v2: server.domain.com, dsname: traffic_out, oid: .1.3.6.1.2.1.2.2.1.16.2, output: 0

From the actual host:

snmpwalk -c public -v 1 localhost .1.3.6.1.2.1.2.2.1.10.2
IF-MIB::ifInOctets.2 = Counter32: 2345351670581

snmpwalk -c public -v 1 localhost .1.3.6.1.2.1.2.2.1.16.2
IF-MIB::ifOutOctets.2 = Counter32: 55186340528955

snmpwalk -c public -v2c localhost .1.3.6.1.2.1.2.2.1.16.2
IF-MIB::ifOutOctets.2 = Counter32: 55186357664546

Hmmm...... On the poller above, the "output" is 0. Is that the problem? What's wrong?? Is the traffic too high? Do I need to increase something? Any help is appreciated. Thanks =)

Yes, please try using snmpv1 instead. Very odd though, can you also run "php -m" and post the output.

I get an SNMP error when I switch to SNMPv1. So I have to use V. 2. Thanks for your consistent help!! Much appreciated....

`php -m` from the host where cacti is on:

Just to eliminate all doupt, turn off php_snmp support in php by editing the php.ini file (if that's possible in Linux), then run it using the native net-snmp binaries. You may have a build problem with php_snmp.

TheWitness

p.s. you can also force this in the include/config.php file by making one manual edit. Pretty self explanitory once you review the file.

I removed php_snmp by `apt-get remove`

Still no graph. This is only happening w/ this particular host. Any other ideas I may try?

Post by **TheWitness** » Wed Jul 19, 2006 8:22 pm

Which host is it? What poller are you using?

Just one particular host is having the issue w/ the Traffic graph. All others, I can see the Traffic graphs just fine. The poller I'm using is cmd.php
