[solved] poller error when trying to use a scheduled task

[marianne.dherens]

Hi guys!

config:

• Operating System:windows XP
  Webserver: Apache2.2
  Cacti: 0.8.7d
  Spine:0.8.7a
  MySQL: 5.0.77
  PHP: 5.2.9
  RRDTool (Cygwin or Win32 version): 1-2.15
  Net-SNMP:5.4.2.1-1
  Cygwin (cygwin1.dll version): 1.5.20
  Plugin Architecture: none

So I created a host, localhost, which is up. I added a few graphics but I am not getting anything displayed (not even a blank graph). The SNMP queries returns results.

Here is what I am trying to do (this is at the end of the cacti manual):

Log into the user account you'll be using for the scheduled task and verify starting a Cacti polling cycle works. Do this by running the following from the command prompt:

php c:/cacti_web_root/cacti/poller.php

The output should look something like the following:

C:\>php c:\inetpub\wwwroot\cacti\poller.php
OK u:0.00 s:0.06 r:1.32
OK u:0.00 s:0.06 r:1.32
OK u:0.00 s:0.16 r:2.59
OK u:0.00 s:0.17 r:2.62

After this has ran once, you should have cacti.log in /cacti/log/ and rrd files in /cacti/rra/.

But I don't get that. This command php c:/cacti_web_root/cacti/poller.php gives me this result:

These 4 files mentionned are created and I found them in the rra folder (my_windows_localhot_cpu12.rrd ...)

I did try it lots of times in more than just the last 5 minutes, so it is also saying that it out the 300 seconds allowed.
I have no idea what's wrong, so any idea is very welcome

Thanks for your help,

Marianne

You get this output because you have logging set to DEBUG

[marianne.dherens]

yes I know, but how do I know that the polling really worked ?

and more importantly why don't I have any graph displayed ?

Thanks for helping

[mcutting]

Have a look at the timestamp on the RRD files - have they ever been updated ?

Also, post a verbose output of the graph in Debug mode.

[BSOD2600]

Turn on graph debugging to find out why no graphs. Looks like cacti is properly getting and storing the data. Possibly NTFS permission issue on cmd.exe / rrdtool.exe.

[marianne.dherens]

About the rrd files: I think they have been updated (since they were created on wenesday and modified on thursday).

Graph debug gives this output:

RRDTool Says:

OK

I also changed the permission on rrdtool.exe to give all permission to all users (was already done on cmd.exe).

Any ideas ?

[marianne.dherens]

I had a look at your installation guide and I could not find any of those users: IUSR_ and IIS_WPG in the rrdtool.exe properties (see attachment).

I also add a look at the user accounts on my computer and the IUSR_ is there (I changed the rights from guest to admin) but still no IIS_WPG. IIS admin is running I checked that too.

What can I do ?

Thanks for your help

[BSOD2600]

Per my installation guide instructions, only Windows 2003 has the IIS_WPG account. Since you're on Windows XP, you'll only have the IUSR_COMPUTERNAME account -- which I do see in that list.

please follow my installation guide, paying attention to the various NTFS permissions which need to be set. The user running the scheduled task also needs permissions -- the installation guide documents this.

Hi

I followed all the instructions in your guide except the one saying to delete all the dll files in the rrdtool folder because if I do that it does not display anything (not even a blank graph which is the case now) and I got a PHP error message when I run the poller.
I did schedule the poller to run every 5 minutes but it actually never stops (I don't know if it is a problem).
I did set up all permissions for all users for all the directories/files you mentionned in your installation guide... but still no graphs

Any idea ?

I enclosed the view of the PHP task. It says that the task started at 11:54 which was the first time it ran but it stopped after 72 minutes or so so I put it back (that is why it is saying "last run time 1:57"). The "next run time" changes every 5 minutes but not the "last run time"

[marianne.dherens]

I just launched manually the poller and it says that it did not run for more than 8000 seconds!

I strongly suggest you stop using the cygwin builds of rrdtool and instead use the W32 ones -- like 1.2.26. Did you install cygwin too?

I did schedule the poller to run every 5 minutes but it actually never stops (I don't know if it is a problem).

yes that IS a big problem. for testing, if you manually run: php cmd.php (with the cacti logging level set to debug), do you see any errors?

I did set up all permissions for all users for all the directories/files you mentionned in your installation guide... but still no graphs

I'm having my doubts, because you missed the IUSR_COMPUTERNAME account on various files as it stated. Have you corrected the NTFS permission problems yet?

Yes I did install it. Shall I remove it ? How do I use the win32 tools ? Are they installed by default ?

Actually it doesn't do that anymore. I checked a box in settings to stop the task if it runs for 4 minutes. So the task start, run for 4 minutes and 1 minute later it starts again and so on...

Yes I really think I did it correctly, which doesn't mean I can't be wrong (see enclosed files)
About PHP though, I did create 2 folders because they were not there: Session and UploadTemp, I don't know if they were supposed to be in the PHP folder or not.
I also enclosed a screenshot of one graph (the other ones show the same things), I have a pic at one point and then nothing.

And still no graph are being displayed ...

*sigh*

yes, remove old rrdtool versions, dlls and cygwin. http://www.gknw.net/mirror/rrdtool/ has the W32 builds of rrdtool. nothing extra to install.

Actually it doesn't do that anymore. I checked a box in settings to stop the task if it runs for 4 minutes. So the task start, run for 4 minutes and 1 minute later it starts again and so on...

That is merely a band-aid for the problem, which is STILL present. Not the best thing to do.

You still are not adding the IIS_COMPUTERNAME account to the various file/folders which is clearly stated in the installation guide.

I've got an idea, delete everything cacti related (including php and mysql) and give my windows installer a try instead http://forums.cacti.net/viewtopic.php?t=14946

[marianne.dherens]

Hi and thanks for your time.

I removed all the dll files and rrdtool old versions and installed the rrdtool-1.2.30-bin-w32 package.

I erased the rule that made the task stop running after 4 minutes, so now it doesn't stop running again (like before).

You still are not adding the IIS_COMPUTERNAME account to the various file/folders which is clearly stated in the installation guide.

I'm sorry, I don't know how I could do that, I tried to add it manually by typing the name but it says that this user doesn't exist.

I also used Process Monitor to find out what files were denied access to and I found nothing denied. I ran the php task with the task scheduler then I did it using the command line and I think there is another problem. On the exemple you show, I can see the process php.exe and rrdtool.exe but all I can see is explorer and svchost (see enclosed snapshot). However I can find the php.exe process ran by explorer.exe

COMPUTERNAME is a variable -- use your real computer name. A default install of IIS on Windows XP/2003 will have an user account named IUSR_something. Its been changed/deleted, then its up to you to rectify that problem.
