can't execute poller.php or cmd.php

[31klev5]

Hello all.

First, sorry for my english. Well, I'm in a training period and I have to make cacti run on a windows 2k computer. All is well installed as the cacti's documentation says, I can log to cacti via my webbrowser but when I want to access the graph it says :

Code: Select all

ERROR: opening 'c:/Pages_web/cacti/rra/cisco_2924_5min_cpu_8.rrd': No such file or directory

In fact no .rrd are built in the rra directory.
My cacti.log looks like :

Code: Select all

When i try to run poller.php via a window command i get (and that is the problem i think) :

Code: Select all

This script is only meant to run at the command line

The problem is that I use a command line!!!! It acts the same when I try to run cmd.php and i don't understand why.

Can you help me please, since last tuesday i can't do anything...

Thanks

1) turn off Web Events logging.
2) clear your log file
3) turn on poller debugging for one cycle and run it (it, being poller.php).
4) What version of cacti, php, mysql, webserver, etc you running?
5) does typing: php -v at the commandline work?

[31klev5]

1)done
2)done
3)how you do that?
4)cacti : 0.8.6c
php : 4.3.10-Win32
mysql server 4.1
apache 1.3.33
net-snmp 5.2.2-1
perl 5.8.6
rrdtool 1.0.49
5)yes il works

Please insure that you are running php.exe (cli) mode. If not, I did notice that there is a 'cli' directory inside of php. Move that php.exe file to the base directory. But first, back up that the fast cgi version first. I created a 'cgi' directory under php and copied it there. You can also change the value of "register_arg..." in the php.ini file to 'On' from 'Off'. Do these things and let me know if it had any affect.

Thank you for these informations. I didn't use the php(cli).exe, if i try with the php(cli).exe in cli directory it works in the run command but it writes "Waiting on 4/4 pollers" without stopping anymore. Waiting on 4/4 pollers.

It now works. But when the task scheduler executes for the first time poller.php, no .rrd is created. I have to run on my own the cmd.php in the run window. is it normal?
Once that done it works properly, but how can i make the window executing the poller.php every 5 minutes not appear on screen.? Can I make it run as a deamon?

[BSOD2600]

1) it takes 2 polling cycles for a rrd file to be created
2) To hide the cmd window that opens up, either run it as a different user than the one logged on OR run a vbs script that will hide the window opening.

when the poller.php is executed twice (or more), no .rrd is made. I really don't understand why I have to run cmd.php manually... Moreover once i have my .rrd my graphs are no longer updated. Cacti is a strange world for me...

31klev5,

With respect to

You need to perform the following steps:

1) Create a UserID in Windows with Admin Rights (Best)
2) Disable that UserID's ability to TS into the box (aka restrict it)
3) Set an unexpiring password for the UserID (This is a service id after all)
4) Create a scheduled task for poller.php and assign it to run under this new UserID

You should resolve the issue with the poller not working though if that is actually the case.
