no rrd files in rra directory

[Wimmo]

Hello,

I just installed Cacti Version 0.8.6b on my fresh installed WIN XP maschine.

I used the XAMPP package, http://www.apachefriends.org/en/xampp-windows.html
XAMPP Windows 1.4.9 Apache HTTPD 2.0.52, MySQL 4.0.21, PHP 5.0.2 + 4.3.9 + PEAR + Switch, MiniPerl 5.8.3,
mod_ssl 2.0.51, Openssl 0.9.7d, PHPMyAdmin 2.6.0 pl1, Webalizer 2.01-10, Mercury Mail Transport System für Win32
und NetWare Systems v4.01a, FileZilla FTP Server 0.9.3, SQLite 2.8.15, ADODB 4.52, Zend Optimizer 2.5.3.
Für Windows 98, 2000, XP.

So far so good. I´m starting the webserver and I´m able to log into cacti. I´m able to import templates and I can add a
new device. And I can attach a template to the new device, a cisco router. When I go to data sources and to the 5Min CPU source,
I can see, that the data is polled from cacti.

But the data is not stored in the rra directory.

With an older version 0.8.5 I saw that it takes some polls to create the rrd-data, but on the new maschine there are no
rrd files. The RRA directory stays empty.

Where might be the mistake.

Best regards

Wimmo

Try changing all your paths from backslashes "\" to frontslashes "/" in Settings->Paths. Post your results.

Since you also have mysqladmin, goto the Cacti database, edit the settings table, look for a row titled path_webroot and change backslashes to forward slashes.

It is important to post your results on this.

Hello,

we tried that first, but that didn´t help us.

Then we looked for path_webroot in the Cacti database, settings table but it´s not there. So we created the field. That didn´t help.
The xampp file contains only a mini-perl. Should we use a complete perl?

Or should we try to import the cacti db again to get the missing field?

Thanks,

Wimmo

I am concerned that your installation did not contain the path_webroot. That indicates to me an installation problem. You should re-attempt the upgrade. Make sure that you have replaced your config.php and all other files before upgrading though.

Attached is a graphic of my Settings table (or a portion of it anyway).

Hi,

I got two problems with cacti. Since I've updated from the v.0.8.6 to 0.8.6a and today to the 0.8.6b, Cacti no more create the rrd files. I see no errors in the poller cache, or when the poller runs.

But: in the poller cache, I dont'see anything related with the new datasources I created.

My second problem, is that I had a few graphs who are no more updated. I can't find them in the poller cache. There are another datasources and graphs which are working well...

Can you help me ?

many many thanks !!


PS: I tried the tip with the path_webroot. I changed the backslashes to forward slashes, but everytime the poller runs, the path_webroot is reseted.`

There is my log, hope this can help...

wow.. here is the file.. finally

[TheWitness]

It looks good. If you graphs are not updating, you should verify your poller cache or event clear it. Then run poller.php from the command line 1 time to look for RRD Error messages. Pipe the output to a file if you have to. Good luck!!

try looking at the permissions on your rrd.log file -
When you go into graph management and then click on a graph choose the debug mode, what does it say?

Hello,

I tried several things. First I put the path_webroot into the cacti database, that didn´t help.

Since it is a fresh installation I dropped the whole cacti db and imported it new from the cacti directory. No error messages.
Then I used mysqladmin to look into the fresh db and I didn´t found the path_webroot entry!

Then I looked at the cacti.sql file from 0.8.6.b and inside is no path_webroot entry. Where does the path_webroot come from, from where is that entry inserted into the cacti db?

Regards Wimmo

The Webroot is created I believe in either install/index.php or poller.php. Can't remember. In any event, you should startup your polling just to be certain.

Hi...

I registered to the forum.. better this way

Well, I was not able to solve the problem, so I downgrade to the version 8.6... I mad a backup before upgrading to the 8.6a and 8.6b...

Now, everything works again
I know that some glitches appear somtimes, but I will do with it.. maybe, in a 8.7 version, all will work fine.

Thanks for your help anyway

dpjoff: the permissions to the log file where ok.. And in the debug mode, it was saying "ok"...
TheWitness: the poller cache was ok, filled with many datasources to poll. But There was some datasources missing, the ones which where not working... For the poller, it was not displaying any error message... so I was a bit "stuck" without knowing where to look for the mistake, or the bug.. so I decided to downgrade...

Again, thanks for your help

Solved: no rrd creation or update:

I'd to use poller.php instead of cmd.php in crontab (or wthatever you will take to force the effect with W2k) to get it work.

After some source code auditing i faced that poller.php was never invoked elsewhere but it contains the function calls to handle rrd files.

Hope that helps
