problem compatibility Thold and new poller.php ???

[fklopfen]

Hello,

I try to set up a monitoring SNMP less than a minute and use Thold to detect problems.

I installed Cacti 0.8.7g. But when I try to make graphs less than a minute (change crontab to start the poller.php 3 times per minute and setting of Cacti), I have an RRD file that has three values by minute, but those values are the same. (rrrdtool update the RRD is run once per minute : saw on Cacti log).

To run the SNMP polling less than a minute, I applied the last file poller.php of Cacti 0.8.7g from the SVN (http://svn.cacti.net/viewvc/cacti/branc ... iew=markup). After, SNMP polling less than one minute working well (3 different values per minute)

But Thold did not work

I modified the 'poller.php' file by adding call function 'api_hook (poller_bottom)' at the end of the file and in the test 'sleep the appripriate Amount of time'. After this change, SNMP polling less than one minute and Thold worked well.

Hello,

On the SVN, the revision 6298 of poller.php file are different between "cacti / cacti / branches / main/poller.php" and "cacti / cacti / branches / 0.8.7/poller.php".

In "0.8.7g" version, I explained the problem above. Looking at the version of the "main", there is the call function "poller_bottom" .

Why the difference, is this normal?

Hello,

According to research on the functioning of Cacti and plugins, I found the problem. there is no real problem.
explanation:
- files on the SVN version 0.8.7g are the base of Cacti (without plugin)
- When adding the PIA, some base files of Cacti (poller.php, database.php, ...)are modified by adding functions PIA. These changes are used by plugins

the missing features discovery on poller.php file are those of PIA .

So there is no problem

Sorry to have made ​​this post, but I began work on Cacti and I have not a comprehensive knowledge of the product.

Rgds,
