snmp_function() error

[namvi]

Hello, I have installed Apache2/cacti8.3/rrdtool1.0.40/mysql3.23.56.
everything install correctly. I can log in the cacti web interface.
I added a host. It works !
but when I want to create a graph I always get the following error !
can anyone tell me what happen please ? Thanks

This is probably caused by Cacti not being able to find your data query XML files. Make sure your "cacti Web Root" and "Web Server Document Root" settings form a valid path when concatinated together. Make sure neither of the paths contain a trailing slash. Lastly, make sure you have files in your 'resource/snmp_queries' directory.

I am having the same problem. I checked the path and it seems fine:

Cacti Web Root - /cacti
Web Server Doc Root - C:/Progra~1/Apache~1/Apache2/htdocs

This is for Apache 2.0 of course.

I have the following files in my Resource/snmp_queries directory:

09/22/2003 04:31p <DIR> .
09/22/2003 04:31p <DIR> ..
08/30/2003 01:13a 1,330 host_disk.xml
08/30/2003 01:13a 3,911 interface.xml
08/30/2003 01:13a 3,049 kbridge.xml
08/30/2003 01:13a 1,379 net-snmp_disk.xml
08/30/2003 01:13a 1,577 netware_cpu.xml
08/30/2003 01:13a 1,944 netware_disk.xml
6 File(s) 13,190 bytes
2 Dir(s) 16,882,323,456 bytes free

Any other avenues I can go down to troubleshoot this? Cacti is no longer collecting stats - and that's bad!!!!

Let's try to debug this. Replace your 'include/snmp_functions.php' with the following:

http://www.raxnet.net/downloads/patches ... ns.php.txt

Along with the error you should see a "GOING TO PARSE:" and hopefully a path after that.

Let me know what you see.

Ian - Here is the response

Warning: implode() [function.implode]: Bad arguments. in C:\Program Files\Apache Group\Apache2\htdocs\cacti\include\snmp_functions.php on line 52
GOING TO PARSE:

No path though???

[raX]

We'll get this narrowed down... Try this one:

http://www.raxnet.net/downloads/patches ... ns.php.txt

Here is the first several lines that I get:

SQL: 'select xml_path from snmp_query where id=', RETURNS:
WEBROOT: C:/Progra~1/Apache~1/Apache2/htdocs, WEBCACTI: /cacti

Warning: implode() [function.implode]: Bad arguments. in C:\Program Files\Apache Group\Apache2\htdocs\cacti\include\snmp_functions.php on line 53

I've duplicated the symptoms and was wondering if any progress has been made.

Originially installed:
Apache-2.0.47\rrdtool-1.0.40\php-4.3.1\mysql-3.23.58\cacti-0.8.3a

Currently running:
IIS5\rrdtool-1.0.40\php-4.3.1\mysql-3.23.58\cacti-0.8.3a

From the debug output above, it is fairly clear what is causing the problem. The problem is that the offending function is called by another function, which is called by yet another function on multiple pages. To ease debugging for me, can someone walk me through the Cacti UI to produce the error? Telling me the exact click that causes the error to appear would be very useful.

Thanks for all of the help debugging this!

Edit: I just ran across a post that might be applicable here.

I hope this helps. I also looked at the other post and made the change to php.ini, but my graphs still lock up my session. I may have more than one problem.
