Cacti doesnt create rrd or it doesnt update new rrd's

Post by Tommi »

Two issues:

1) Cacti doesn't create the rrd-file, when i'm setting it from cacti-console -> Data sources. With "Data Source Debug Mode" on, cacti doesn't give any warnings. Trying to create a graph from non-existing rrd, gives the regular

Code: Select all

"RRDTool Says:
ERROR: opening '<cacti_home>/rra/server_via_ssh_load_5min_33.rrd': No such file or directory "
Permissions should be ok, on the <cacti_home>/rra -directory

Code: Select all

-sh-3.00$ ls -la rra/
total 1876
drwxrwxrwx   2 cacti cacti   4096 Jul 17 14:28 .
drwxr-xr-x  16 cacti cacti   4096 Jul 17 14:29 ..
<snip> 
-rwxrwxr-x   1 cacti cacti  47840 Jul 17 15:07 serveri_snmp_oid_27.rrd
<snip>
Ofcourse i can create the rrd-file by myself, but then comes the second issue.

2) Cacti doesn't update the rrd-files. Old ones work right, but newly created files don't get any new data. I'm using basic "ucd/net" -templates or snmp-templates for data collection. Nothing happens and files timestamp remain same with create-time.

I have checked the "Debug NaN's in your graphs" instructions but those didn't help.

Show me your Cacti cron settings. What user are your running poller.php as? Can you do the following:

Code: Select all

su - <cron_user_running_cacti_poller>
cd /var/www/html/cacti
php -q poller.php
php -q cmd.php

So the problem might be on a misconfigured rrd-update (wrong time or same time as last input was made)?

Those DS[XX] propably refer to datasources? Datasources 1-26 are old ones (working ok) but newer ones don't even show up on that listing... So cacti doesn't accept new ones ? (which i have made myself, by copying the create command from cacti. Otherwise the new ones wouldn't even exist..)

I suspect that you have too many entries in your poller_output table. If you look in SVN, you will find a poller_output_clean.php file. Don't get the most recent, but rather the prior version and then run it. It will update your missing RRD data.

Then, make sure that /etc/php.ini have a high memory_limit, say 256mbytes so that this does not happen again.

Now i have the same problem again. But this time it didn't occur right away. Basic problem is, that cacti doesn't create all of the rrd-files and of course the doesn't update those either... This seems to be related on the template.

First i created a php-file, for collectin snmp data from WebLogic servers. Then i started working via cacti as I declared the data input method (Console -> Data Input Methods -> add), created data templates (Console -> Data Templates -> add) and made graph template (Console -> Graph Templates -> add).

I tested my new script, it had some problems (my fault) but i fixed those. Rrd-files were created and some graphics was visible. Then I decided to change the php-script littlebit and that change demanded a small change also to the Data Input Method . And now if i create new rrd:s from these templates, cacti doesn't create the rrd-file at all.

And I had caused the problem again. Had wrong name on data input method as a snmp community pharse... It's suppose to be <snmp_community> as a script parameter, not <wls_community> or whatever. :roll:

Always double-check. And then triple-check on the next day. And so on...

And as result from the fourth check I noticed that Data template didn't have any "Data Input Method" (Console -> Data Templates -> (Edit) ) set... Now this problem only occured with my newly created php-script, but still took two days of looking for the trouble...

It seems to be, that new rrd:s are not created immediately on next update, but after a few rounds of cacti poller.
