Missing rrd-files

[Herman]

Hi

I am running Cacti 0.8.6c with rrd-tool 1.0.49 on Solaris. I wish to report on MS Exchange OID's and so I defined the necessary data source/query and template. The graph is nicely there with the variable/OID I wish to poll. Nevertheless, the data is not present. After checking a few things, the rrd-file that should have been created, is not there in the filesystem whereas cacti named it in the datasource.

Anyone an idea?

Thanks a lot.

Is any valid data being returned from the OID (turn on debugging and look in the log) ?

This exact same thing is happening to me. I have just installed this and there isn't a single rrd being created in the rra/ folder. The only error message i get in my apache log file is *.rrd': No such file or directory.

I also have Graph Debugging on and this is the error that i get next to the red X

ERROR: opening '/usr/local/src/cacti-0.8.6f/rra/sbs02_snmp_oid_28.rrd': No such file or directory

The only thing that i get in the cacti log is the info from the poller.php What could possibly be going on that is not letting the system create rrd files?

i had this at install time,
i think most my issues were around folder permissions for the user running the poller, crontab config and output legibility too..

When i want to confirm data source problems, i use > tcpdump -n host 172.25.2.63 and port 161 -s 200
and run php poller.php.

Ok, but which debugging exactly? (sorry, I am rather new to Cacti)

Running the dataquery in verbose gives me the right value for the requested OID.

I put the poller in debug and verified the contents for the device in question.
(see attached). There is not even reference to the necessary rrd file although the data source for this item clearly shows <path_rra>/sgntstr14_xchgpercentcpu_301.rrd.

There is your problem and why a rrd file has not been created. No valid data has been returned.

If you manually run that command, does it return anything? You might need to run dcomcnfg and change your security settings so it will work for remote users.

Thanks for your reply, but that is a downloaded template, not my data query. Actually I wish to get my data with a plain SNMP query, no script/cmd.

It should still create the rrd file with unknown data. Please run "php poller.php" from the command line and paste it's output into the forum (attachment). You can have the setting set to LOW for this test.

Thanks for looking into this. The requested PHP-output is attached. For some reason it complaints about "Can't open perl script "/opt/cacti/cacti-0.8.6c/scripts/w32_exch_query_isstats.pl": No such file or directory". But that was an imported template which has nothing to do with the snmp query I am running and which is not the problem.

I use SNMP or SNMP query as Data Input Method and use a simple query <path_cacti>/resource/snmp_queries/snmp_exchange.xml to fetch the Exchange CPU OID. Nothing fancy. Only the rrd file that was named by cacti is not in the rra directory.

for the host that is giving you problems, run the following:

php <path_cacti>/cmd.php <host_id> <host_id>

Run it in DEBUG. You will be enlightened.

OUTPUT OF THE COMMAND:

$ php /opt/cacti/cacti-0.8.6c/cmd.php 10.1.1.14
#!/usr/bin/php -q

Notice: Undefined variable: polling_items in /opt/cacti/cacti-0.8.6c/cmd.php on line 97

I checked "debug" for the log as you said. Now, I do not even get any entry in the log for the target host apparently.

I am still not "enlightened"...

You did not follow the syntax TheWitness gave you. Host_ID is interal to cacti, no its IP. Look through the log file for which host(s) are giving you problems. Pay attention to what host number is. Then re-run the command TheWitness told you.

Xcuse me, but what is the syntax, there is 2 times <host_id> in the command, which is which? The troublesome host should be "Host[13]".
