The poller hangs

noisesinmyhead · Post by **noisesinmyhead** » Sat Jan 06, 2007 2:40 am

Well, I've filtered the Filemon results, because the system has many processes and the log was flooded with useless entires. It seems that I had messed up my PHP 5.1.6 install, so I fixed it and many of my problems are solved now. I switched the logging to medium and ran cmd.php:

Code: Select all

F:\>c:\php-5.1.6-Win32\php.exe -c c:\php-5.1.6-Win32\ f:\httpd\cacti\cmd.php

The log contains 100% the same as above. When I run poller.php it is the same:

Code: Select all

F:\>c:\php-5.1.6-Win32\php.exe -c c:\php-5.1.6-Win32\ f:\httpd\cacti\poller.php

When I swtich the poller to cactid:

Code: Select all

C:\cacti>cactid
CACTID: Using cactid config file [cactid.conf]
CACTID: #

C:\cacti>

May I "solve" the problem by using cmd.php or cactid in my cronjob instead of poller.php? (EDIT: No, I can't

)

Looks to be working a lot better now -- congrats.

I'm curious, what exactly was messed up with your php installation?

noisesinmyhead · Post by **noisesinmyhead** » Sat Jan 06, 2007 1:23 pm

I have used the .ini file from the other install of PHP for my webserver, which has the "exec" function and the "socket" module disabled.

And it looks that the mibs should be in f:\usr when I use scripts on drive f:, I thought that c:\usr is enough... Until I looked for the warnings in the execution of the scripts. I had a lot of troubles because of my faults in the PHP configuration, now I have triple checked it, but the poller still hangs...

As soon as I have enough free time, I'll test another versions of PHP/Cacti. I think PHP 4 will be a good starting point, but it has some major "built-in" problems with MySQL 5 (and especially UTF8).

The next version of Cactid will provide better messages. You can pull from SVN now if you want that right away, but if cmd.php is ok for now, I would simply wait.

FYI I'm running the config in my sig (PHP 4.4.4 & MySQL 5.0.24) with cacti no problem, although I do use cactid for polling. (but then I know how to set up a php.ini having done a bit of PHP a while ago haha)

The poller result you posted shows working polls so I'm assuming some of your graphs have stuff in them now

You posted results using cactid and there's a line with CACTID: # does that show on your screen as a smiley face?

Anyway I'm a bit trashed sorry thought I'd check in and see how you were getting on hehe nice one

ps. forum broken while posting again hooray for the clipboard fancy writing a new one when you get a sec Mr. Witness?

It's good to be trashed from time to time...

Well, I didn't want offtopics. Yes, this config is running here too... And it works really well. Unless I try UTF8 charset for MySQL, because I use cyrillic characters really often. Then everything is filled with warnings - "Charset not compiled" and other fun stuff. It's not fatal for my wiki or my blog (warnings fly to /dev/null), it only floods the Apache logs, but it causes major problems with Cacti. Try this config now and tell me the result on PM.

Hint: PHP5 uses a little bit newer "mysql" module, which doesn't have such problems with UTF-8, cp1251 and others.

Yes, there are graphs, but the poller is still broken. And it's still a problem (I think).

Maybe I should choose the leet way and let the poller reach the max exec time of PHP? Well, it still doesn't work.

My English is not very good, but I guess it should be funny. HaHa!

I really think that somebody should lock this topic, because I have solved (nearly) all of my problems and most of them are my mistakes. It's obvious that there's a bug somewhere, but I think I'm not the right man to help you diagnose it. Thanks to all of you!

Why don't you first fix the warning messages:

"Charset not compiled"

I don't have the time to change charsets. Although, I think if you dump your database and then manually change the encoding and then re-import it something might happen.

In case some people have the same problem, and try nearly everything to debug this, like checking permissions, using Filemon, debug logging-level... You would probably like to know that for me, the only problem was that in my cactid.conf I had written the hostname (but not localhost) instead of the IP. Putting this back to the IP made this work instantly !!

Hi,

I am having the same issue; however, when installing an earlier version of Cacti (d) it does not hang at all, but I do need version (j) to run, so please let me know if you figured out how to fix the hang issue.
