After upgrade to 0.8.7 SNMP - disk graphs are empty

Beaujolais · Post by **Beaujolais** » Thu Oct 25, 2007 9:50 pm

After upgrading from 0.8.6i to 0.8.7 all "SNMP - Get Mounted Partitions" based graphs are empty.
These graphs are OK after upgrade:
Graph templates:
Host MIB - Logged in Users (standard)
Host MIB - Processes (standard)
ucd/net - CPU Usage (standard)
ucd/net - Load Average (standard)
ucd/net - Memory Usage (standard)
Data queries:
Linux - hddtemp - disk temperature (custom)
SNMP - Get Processor Information (standard)
SNMP - Interface Statistics (standard)

This one is showing empty graph:
SNMP - Get Mounted Partitions

Even though the debug seems to be OK

RRDTool Says:

OK

But the graph is since the upgrade empty as shown on the picture.
I've tried deleting the graphs, all data sources and recreating but nothing helped.
I've made sure that none of the scripts from 0.8.7 were not overwritten with from the old version.

Any idea what went wrong?

thanks

Well that is not good. Turn logging to medium and then do the following:

1) Note the host_id from Cacti
2) run "php -q <path_to_cacti>/cmd.php <host_id> <host_id>

Record the output. Look for the Host disk stuff. If it does not appear:

1) Check the poller cache. If not there
2) Repopulate the poller cache and see if it appears

Post your results.

That, in fact, is not the poller cache. That is graph debug. Poller Cache is under System Utilities.

If that sensors script is script server based, it could be hosing your disk graphs. Fix that issue first. You need to alter any script that used snmp to use the revised syntax which includes data for snmpv3. I think once you do that, you should be ok.

I would audit your scripts right away. The fix is quite simple and is posted as a part of the upgrade instructions.

Seeing that, you may have copied over your "old" host disk template from your prior installation. That will break the host disk and cpu graphs as well. You should always keep the Cacti XML and Scripts if they are newer.

OK, I'll check.

For sure not. After I did the upgrade and copied old scripts I've again copied new scripts from 0.8.7 to make sure the new are indeed new.

The lmsensors script is not mine, I've got it from this forum.
Not quite sure what to fix, can you please point me to the upgrade documentation?
I've fixed config.php to global.php that's all.

Much appreciated

Post by **TheWitness** » Thu Oct 25, 2007 10:41 pm

I think that is it. Does it still bomb out? Can you expand your cmd.php scope to more hosts and see if you get other errors?

I've tried other hosts and I only see the lmsensors error on the hosts that are being polled for lmsensors. Only those errors shown above, no other errors.
BTW: CPU graphs are OK.

I'm not as such expert to be able to fix this I guess. I can try to copy once again the disk template from 0.8.7.tgz but not sure which file it is.

Guess, will have to start from scratch and try the lmsensors from beginning

This seems to be the problem, but I'm clueless how to fix it

Code: Select all

                        $scratch = cacti_snmp_get($snmp_hostname,
                                $snmp_community,
                                ($oid[2][1] . "." . $cmdoutput[$cmdoutputcount][0]),
                                $snmp_version,
                                $snmp_username,
                                $snmp_password,
                                $snmp_port,
                                $snmp_timeout);

That one was for the host disk. The new calling syntax for the SNMP* functions is the following:

Code: Select all

cacti_snmp_get($hostname, $community, $oid, $version, $username, $password, $auth_proto, $priv_pass, $priv_proto, $context, $port = 161, $timeout = 500, $retries = 0, $environ = SNMP_POLLER)

So, the new ones are the following:

$auto_proto
$priv_pass
$priv_proto,
$context

So, simply add then, they can be blank if you are not using snmpV3.
