Cacti

Oscar,

From your rrdtool output, it just looks like you haven't waited long enough for data to accumulate in order to be able to show anything significant. Are you still having this problem?

This sounds like a snmp agent issue instead of a Cacti issue. You might set the Cacti poller logging level to DEBUG and check the output to see if there are any more clues. Also, searching google for your snmp error returns some interesting results: http://www.google.com/search?q=Reason%3A+%28noSuch...

Once you begin running the poller on a regular basis, you probably need to wait about 5 to 10 minutes before your graphs stop showing NaN as values.

laaremu, I got your private message. Please post your RRDTool Command output for the graph in question. Not the "RRDTool Says: OK", but the debug outpt from the RRDTool command itself. If you do not see the RRDTool Command output when you turn on graph debug mode, you are most likely using...

And when you removed the jnxFruIndex field definition, you also removed jnxFruIndex from the index_order field?

Can you confirm that the <cacti path>/rra/ directory is writable by the same user and group that you run the poller.php script as?

Well, your query output does look better this time. But why did you change your oid_index to .1.3.6.1.4.1.2636.3.1.13.1.1? The one you were using before worked just fine; I think you just needed to remove the empty jnxFruIndex field.

What does your snmp query look like now that you changed it?

I believe it is... XML is as follows: The SNMP query xml that you have here is referencing more than just the .1.3.6.1.4.1.2636.3.1.13.1.5 OID that you posted the above output for. You might post a walk of the full snmp table that this SNMP Indexed Query is using. But, looking at the XML, is the jn...

From the snmpwalk that you've given us, it looks like whatever data you are trying to query is not in the form of an indexed snmp table and not really suited to a SNMP Indexed Query. You might consider attaching a copy of the XML file (juniper_fru.xml) that defines your SNMP query so that we can bet...

I was asking for the specific OID that you were using for your graph and the values returned from an snmpwalk for that OID. Please only return numerical values since I do not have a MIB file to compare. Also, if you would post the debug output from your graph in cacti, it would help in understanding...

i want to create a graph taht display only the calculation ( current - last value). To make a graph item invisible, set it's Color to "None" and leave the Text Format field empty. So, for your graph, you need to add two datasources that would normally graph, but make them invisible. So, C...

As far as I know, the actual data is stored on rrd files, and cacti always generate the graphs looking at those rrd files right ? You spoke about migrating MySql database, but you didn't say anything about the rrd files. For example, all query results are stored on mysql?? or they are only stored o...

My OS X 10.4 machine has all three installed by default. It's really just a matter of getting cacti installed.

First of all thank you for your quick answer. You are absolutly right i runned myisamchk without locking it or shutting down the mysql-server. i mentioned the raid just because of the possible harddisk-error as a reason for the problem. nor the os neither the mysql-service stopped when the error ac...

I know of no guide, but I've done this a few times. I would not upgrade cacti until you have successfully migrated your 0.8.6d version over and you know for sure it's 100% properly working. It's better to only deal with one potential problem at a time so you know where the fault lies. For the most p...
