0.8.6 Problems with Task Scheduler

vtmgr · Post by **vtmgr** » Mon Sep 20, 2004 3:38 pm

We just upgraded to 0.8.6, and all went very smoothly, except that
I can't get the poller to work under task scheduler.

Works fine from the command line, but just flashes a DOS box, and disappears when running from Windows Task scheduler.

Running on IIS 6, PHP 4.3.8, mySQL.

same behaviour with nncron. Cron job runs fine, just doesn't do anything.

I have tried various combinations of rights and running as...

It was working before on 0.8.5.

Thanks in advance for your help.

b.t.w Very nice job on 0.8.6!

Hi Vtmgr,

Do you call poller.php? In previous version you needed to call cmd.php.
Command line in task sheduler must be something like c:\php\php.exe c:\inetpub\wwwroot\cacti\poller.php (check the install on win32 manual)

Cheers,
Teppe

All,

Please download the latest pre-release of 0.8.6a to correct intermittant graphing problems. It is dated September 21st. Thanks for the good word, but let me tell you, it didn't go off without a few nasty hitches.

The answer to your question is yes, you do schedule poller.php. Please note, if you use PHP 5.x, you need to schedule PHP-WIN.EXE ... and not PHP.EXE.

Thanks for help...

Yes, I am scheduling poller. Command line is:

"d:\php\php.exe d:\inetpub\wwwroot\cacti\poller.php"

I have tried changing the execution directory, and running it as system, administrator, etc. to no avail.

I _did_ put it in a .bat wrapper to see if I could see the message, and it includes this: This script is only meant to run at the command line.

So now I am tring to learn enough php to figure out what this is telling me.

Still runs if I open a command window, and run the above command line. Many new errors, but that is the subject of another post...

vtmgr,

First, apply the pre-release patch to 0.8.6a. It can be located at http://www.cacti.net/downloads/beta

Then, please state the following:

PHP Version
OS Version
Apache/IIS Version
Net-SNMP Version (if using CACTID)
Using cmd.php or cactid
Cygwin Installed

You should only have to modify three lines in config.php if using cmd.php as the poller. Therefore, don't make any other changes. You also must be more specific with what your problems are.

Thanks,

TheWitness

OK, sorry for ambiguity.

I am running:

PHP Version: 4.3.8
OS Version: Windows 2003 Server
Apache/IIS Version: IIS 6
Net-SNMP Version (if using CACTID): 5.1.2
Using cmd.php or cactid: cmd.php (tried cactid, but it just hangs)
Cygwin Installed: no

Updated to 0.8.6a

adjusted only the three lines in config.php.

The problem is poller.php dies immediately, with the following message:

 This script is only meant to run at the command line.

And I guess the question is why poller.php thinks it is _not_ being run from a command line.

Thanks for your help with this.

Clear logfile, disable scheduled task, turn logging to DEBUG, open a command window and run c:\php\php.exe c:\<webroot>\cacti\poller.php and post the results from the command line and logfile.

Thanks,

This does not (to my eye) address the poller issue, but does show some interesting things.

Also, I tried changing the php executable I was pointing at to the one in the cli directory (d:\php\cli\php.exe).

It seems to run, although I am not updating yet (poller is timing out, as shown in the logfile).

The results I am sending are from running as you specified, not as mentioned above.

Thanks again.

forgot to include...

rrdtool version 1.0.48

First of all, you are getting the following output:

'cat' is not recognized as an internal or external command,
operable program or batch file.
'cat' is not recognized as an internal or external command,
operable program or batch file.
'uptime' is not recognized as an internal or external command,
operable program or batch file.
'who' is not recognized as an internal or external command,
operable program or batch file.

This indicates that your are attempting to run programs that don't exist. You are likely using the default "localhost" template provided by Cacti. It does not work on most Windows systems without a supplemental addons to that environment. So delete it if you are using it.

More comments to follow as I review your output.

I am interested in the following lines. They will go away once you delete the bad host selections, but I need to modify this code to be a little better behaved.

You also have a problem with the following perl script. You should run from the command line and clean it up, whatever it is.

It also appears that because of the STDERR issue mentioned a note or two ago, the RRDTool is locking up. I will change the behavior and repost a new pre-release tonight. Thanks for the information. For now, if you clean up all the mischivous perl scripts and hosts, you will start generating output.

I will be posting to the web site a revised RRD.PHP file to correct the undesirable behavior in the poller.

Thanks Again,

TheWitness

Wow! Such support! If only our internal developers understood their code as well.

but I digress...

I will track down and remove the errant Unix commands.

Your middle two posts seem to be missing something. just had the php complaint.

And I will check for the new rrd.php tomorrow AM. Do I just replace the module, or do a full upgrade. or...?

as always, thanks for the hard work, and the wonderful tool all of you have crafted.

Guest,

Ian made a few more changes so I suggest you simply download the entire package. Unfortunately, I am having problems with the RRDTool process pipe and may have to abandon it completely due to compatability problems between *nix and Windows. That makes me sad!!
