Getting error with PHP scripts ... cgi vs cli

pbulteel · Post by **pbulteel** » Thu Nov 24, 2005 8:14 am

I saw that the ss_fping and ss_host* scripts all have the -q and disable errors, etc in them. However on PHP 4.3.11 I seem to have problems because I get the headers showing up!

I'm talking about the...
text\html
X-Powered-by: PHP

stuff... any way I can force it off in the php.ini? all google searches returned nothing helpful. I'm not sure if it's a bug or what... probably is. I need to update the version here, but thought I'd check here first.

Thanks,

-P

Infortunately didn't work ... this is what's in the log

Syntax looks good, what happens when you debug the script server?

1) "php script_server.php" (cgi version)

2) /var/www/html/cacti-0.8.6g/scripts/ss_fping.php ss_fping 10.53.96.250 20 TCP 80

3) "quit"

Between 2 and 3, you should have gotten a response.

I also need to update lib/poller.php. We introduced some timeout logic that appears to be very unhappy in PHP. Will rip out and repost. Just send me a PM reminder as it's early morning and I'm about to goto work.

This is what I got

php script_server.php

This is the problem:

Content-type: text/html
X-Powered-By: PHP/4.3.11

This is quite ODD. The script server simply includes a file and run's, why it's generating the stuff that's supposed to be suppressed by "-q" is perplexing.

Yes, I kinda knew that was the problem, and looking through everything ... I couldn't figure (still can't) out why it's giving that! (It's the cli vs cgi) but with the -q and other stuff in it... that shouldn't show...

So... any ideas what to look for?

I still haven't fixed this but I notice that this error occurs on the ss_host_disk.php file for certain hosts only. This tells me that something is cached somewhere. Now I cleared the poller, but that didn't help, so I'm wondering how I can do that manually (and safely) to test.

TheWitness: I saw you tried to msg me, but I was already at home... I'm in London =P I will try to get in touch with you somehow.

Thanks,

You may need to place the "I'm running command line mode" directive at the head of the two files:

ss_fping.php and script_server.php

Try both of those and let me know if you have any luck. I have not access to IM this morning.

If by that you mean

#!/usr/bin/php -q

I just added that to the script_server.php since it doesn't have it. It only had

$no_http_headers = true;

However the other scripts do have it. I'll update this post once the poller goes through a few cycles.

I am seeing some REALLY strange behaviour like ss_host_cpu showing information that I would imagine would get returned by the ss_fping.php script. ie, min, ave, max, dev, loss ...

I am confused. =\

Do I need to clear out the poller cache?

BTW here's the sample

12/06/2005 04:20:02 PM - CMDPHP: Poller[0] Host[3] DS[23] SERVER: /var/www/html/cacti-0.8.6g/scripts/ss_host_cpu.php ss_host_cpu 10.53.98.145 3 1:161:800:pbulteel:::MD5::[None] get usage 0, output: min:0.1900 avg:0.2430 max:0.5300 dev:0.0792 loss:0.0000

When I run it manually
php -q ../script_server.php
PHP Script Server has Started - Parent is cmd
/var/www/html/cacti-0.8.6g/scripts/ss_host_cpu.php ss_host_cpu 10.53.98.145 3 1:161:800:pbulteel:::MD5::[None] get usage 0

Looks like it's cached?

From looking through the logs I see that the "answer" to the cpu query shows up as a disk query further down, this leads me to believe that something is being cached somewhere.
