Apache stats script error: output: U

[clockwork]

So apache stats stopped working (Nan's in the graphs, cause the script doesnt seem to be working)

Code: Select all

05/16/2007 02:20:24 PM - CACTID: Poller[0] Host[68] DS[3083] WARNING: Result from SCRIPT not valid. Partial Result: ...
05/16/2007 02:20:24 PM - CACTID: Poller[0] Host[68] DS[3083] SCRIPT: /usr/bin/perl /opt/cacti/scripts/ws_apachestats.pl 10.6.8.24
, output: U

Running the script as the cacti user actually works just fine. So does calling cactid like so:

Code: Select all

cacti@cacti01:/opt/cacti$ ./cactid -f=68 -l=68
CACTID: Using cactid config file [/etc/cactid.conf]

So what exactly am I missing. Everything appears to work just fine, but its throwing a non-descriptive error.

Is the script named /opt/cacti/scripts/ws_apachestats.pl~ or /opt/cacti/scripts/ws_apachestats.pl?
Reinhard

[clockwork]

its actually the exact same script. A long time ago when we were having some trouble we made a copy and poked it a bit, but everything ended up getting reverted once we determined that the script wasnt the issue.

I renamed the stuff in cacti's UI after running an md5 on the scripts. Same result. run by hand it works, run via direct cactid it works, run via normal poller cron method and it fails.

[gandalf]

Is it an option to modify this copy of the script to simply output a constant integer? Just to verify, that calling the script is ok?
Reinhard

[clockwork]

So I have the script basically outputting the variable it was called with, and now I get the following:

Code: Select all

05/17/2007 04:35:22 PM - CACTID: Poller[0] Host[68] DS[3093] SCRIPT: /usr/bin/perl /opt/cacti/scripts/ws_apachestats.pl~ 10.6.8.24, output

05/17/2007 04:35:22 PM - CACTID: Poller[0] Host[68] DS[3094] SCRIPT: /usr/bin/perl /opt/cacti/scripts/ws_apachestats.pl~ 10.6.8.24, output

: 10.6.8.24

Which to my eyes looks fine. So its something weird in the output thats coming from the script. What I dont understand is why cactid works when I run it manually, and why the script works when I run it manually but for some reason it fails via the poller calling cactid.

[gandalf]

The script is using wget? Is wget in the path of cactiuser? Else, please provide /full/path/to/wget
Reinhard

[clockwork]

Well hardcoding wget (and/or re-importing the entire template set) worked, which is odd because its in the cacti users path and the cacti user could exec it.

Thanks for the help.

This should be re-written using php script server. PHP has a "file" command that will essentially read a string into an array. For example:

$my_array = file("http://big-dogs.com?ab=c&d=ef");

Will return your output data in the form of an array that can then be parsed one line at a time. No need to have high load launching both the Perl script and wget binaries.

I think it actually has been rewritten accordingly (at least thats what a cursory glance would lead me to believe) however the most useful data we get about apache is a log-scrape script that uses a custom log that reports service times, errors and the like which dumps into a cacti graph.

The actual stats are bonus.
