cacti 0.8.6j and rrd's not being created

[phpgold]

Hi all,

I need a little help with this one. I created a new xml file to query snmp and applied it as a data template. I also created a graph template and the data query for it.

When I add the template to a device and then run the verbose query from the device it returns the right information. I then click on the create graph at the top of the device page and it shows the new information index properly. I choose the devices I want to monitor and choose the graph type and hit create which returns:

Created graph: machine01.help.local - snmp Activity -

I then go to data sources and look at the new datasource which shows the proper information in the data source debug.

Under the graph it shows the error "ERROR: opening '/var/www/html/cacti/rra/machine01.help.local/machine01_help_local_snmpactivity_2211.rrd': No such file or directory"

I look in the cacti database in the poller_item table and it seems the new data query is not in there.

What would be the possible cause of a new data query not being added to the poller_item table in the mysql cacti database?

Any help is appreciated.

Goto your data query and edit the Associated Graph Template and make sure the checkbox to the right of the data sources is checked. Then resave your devices that contain these graphs.

In the Associated Graph Template the checkboxes are there and assigned to the appropriate xml fields and are checked off on the right.

The data sources are even in the data sources menu for that box but when I rebuild the poller database the new polled devices never show up.

I even checked the poller_item table and they never show up in there either.

I have tried rebuilding from scratch but it keeps giving me the same thing.

When I do the verbose query under devices for debugging it returns the correct information.

Thanks for the help Witness.......

Have you been able to edit the XML file properly in Internet Exploiter? It's a pretty good syntax checker.

XML notepad 2007 is also a handy new, free tool.

Here is the xml I'm using for the data query. It seems to work with no errors. In order for this query to work you have to install extra software on the server for it to recognize the oid.

It seems with both the xml notepad and ie that it says there are no errors. I even modified the xml to generate an error message(which it did). So I know the xml is running properly.

When I query those oid's with a mib browser it returns the correct data so I know that the data is available and able to be queried.

I've tried going back versions of cacti which had no effect.

Thanks to everyone for their help but I found what the problem was. It seems that there was a problem with the xml even though the syntax was correct(it didn't show any errors).

Thanks...

would you mind pointing out the solution? I am kinda fighting a similar war here and I would like to see what the fix was and compare it to my problem.

soloslinger,

if you have a look at my xml I made a mistake on the <index_order> line. The index_order "DiskInstance" is not the same as line 11 <dskInstance>.

If these are not correct it looks like cacti will not enter the information into the poller_item table and it will not show up in the poller cache when you rebuild it.

Later....

kk Ill look into both more. There have been more pressing things to work on as of late but Ill do what I can when I get caught up.
