not triggering

[ripperza]

have 0.8.8a installed (reinstalled over an older version - sorry don't remember the version; was an ezcacti install that got horribly broken) with thold -v0.4.9-3

In terms of setup there is no error both in the webbrowser nor in the logs (even in debug logging mode)

I can add a threshold both via the datasource manually and through a threshold template with no errors.

I then get a log entry saying " - THOLD: Checking Threshold:'" listing the correct host and graph id.

The problem is that the threshold isn't triggered both with deviation and Hi/Low modes.

Aside from the 1 line indicating that the threshold is being checked - there is no other mention of thold events (even after enabling thold -> syslogging).

Anyone know how I can call this plugin from the commandline so I can troubleshoot?

Thanks

So on a hunch I built a new cacti to test things on, building from scratch, no upgrades and potential problems being brought forward and tholds work fine there.
Here's the differences that are apparent to me:

versions of cacti and thold are identical: Cacti Version 0.8.8a, Thold 0.4.9

Not Working: CentOS release 4.9 (Final)
Working: Debian 6.0.5

Not working: PHP 4.3.9 (cgi) (built: Feb 2 2012 18:53:42)
Working: PHP 5.3.3-7+squeeze9 with Suhosin-Patch (cli) (built: May 8 2012 10:41:34)

Not working: Apache/2.0.52
Working: Apache/2.2.16

I still think the only way I'm going to track this down is to be able to call the thold sctipts from the command line so I can see any hidden error messages.

I forgot to mention, I've already tested while "Disable Legacy Notifications" is enabled and not. (obviously setting up the notification lists as needed if legacy is switched off)

I am having the same problem.
Our machine was old and we wanted to use the latest versions.

I am using the following versions of software:
apache: v2.0.52
mysql: v4.1.20
PHP: v4.3.9

Cacti: v0.8.8a (Upgraded from Cacti 0.8.7b)
PIA: v3.1
Settings: v0.71
THold: v0.5 (I got it from CactiEZ 0.7)

I don't want to loose the current gathered statistics,
so I did an upgrade with the current machine to the newest Cacti.


After the upgrade I noticed that thresholds never triggered.
I tried many things and finally wanted te debug the PHP.
Then I found out that poller.php was giving an error:

[12-Feb-2013 16:45:12] PHP Fatal error: Call to undefined function: log_cacti_stats() in /var/www/html/poller.php on line 377

log_cacti_stats() is defined in the poller.php and seems for as far as I can understand perfectly in order.


I found out this error by changing the 'error_log =' line in /etc/php.ini to create a log file and created the logfile with permissions for apache.
Then I did 'tail -f /var/log/phperrorlog' to track errors while the poller was running. (/var/log/phperrorlog is the file I entered after error_log in php.ini)

*fixed*

You hit the nail on the head.

I used the trick you suggested, error_log = in the php.ini, and the same error showed up. This has got to be the single best tip for debugging if setting the internal cacti debug log level setting.

localhost php[30431]: PHP Fatal error: Call to undefined function: log_cacti_stats() in /var/www/html/poller.php on line 377

So all I did to fix the problem is I moved the function log_cacti_stats() to the top of the poller.php script. Actually, I think, it only needs to go above where it's used in the script.

Thresholds working now.

Course now the question is - is this a cacti patch or a thold patch?

[ripperza]

Small update. I compared the "fresh install" version - the poller.php file was the same which in theory means that neither should have been working.

I'll post this to bugs and see what the clever guys come up with.

[petergaaf]

After changing the poller.php like you indicated, I still got errors in the php error log:

PHP Notice: Use of undefined constant DATE_RFC822 - assumed 'DATE_RFC822' in /var/www/html/plugins/thold/thold_functions.php on line 1326

PHP Fatal error: Class weathermapnode: Cannot inherit from undefined class weathermapitem in /var/www/html/plugins/weathermap/WeatherMapNode.class.php on line 9


Cacti and THold seem to work properly, but since errors are reported, something must be wrong.

[ripperza]

I don't have weathermap installed. All that's happened is that moving the function that high up the poller.php script doesn't set the dateformat in time. I posted to bugs.cacti.net so we'll see what the pros say about it. If you want to experiment you could just move the log_cacti_stats function further down the script. Hopefully at some point weathermap will start working again while the thold error doesn't come back... hopefully.
