poller.php not running script

[taik0]

First, sorry for my poor english.
Now the problem:

Hi I created a Data Input Method (script/command) who requests 1 input field and return 6 output fields. I've check the script and works fine.
That's the input string: perl <path_cacti>/scripts/mailq.pl <ip>

After that I've created a Data Template with that 'DIM' what when I create a Data Source ask about the DS Name, DS Path (rrd file) and the Custom Field (the hostname or ip). I assigned that DS to a host previously created in Devices without SNMP support.

All seems to be ok, so I create a Graph Template with 4 Items (2 Area and 2 gprint) from the DT from before.

Later I create a graph under Graph Management. I choose to use my new GT and assign the host and I select the 2 fields from the DS/GT.

The graph it's generated ok (and all debug's say that all it's ok).

But the graph it's never filled with data and when I run manually cmd.php or poller.php I can't see my script running (I've other script/commands running and they're executed but without any template).

Anyone can give me any clue about that?

Thanks in advance.

I'm running Cacti 0.8.6c under a x86 Debian. No deb's used all it's compiled.

I have had a similar problem for some time.
I have not found a solution yet, but what I did was reinstall everything and then apply all the patches.

After that, I used the "Clear Poller Cache" system utility.
At least the poller now calls the scripts, but there are stil some problems.

I would love to hear what the correct solution is.

I tried 'Clear poller cache' too and It stills the same.

Cactid or cmd.php?

cmd.php

[DeepFreez]

Using cmd.php too.
I tried to duplicate the working setup on my live server, but I ran into the exact same problem... poller not running the queries.
I dont realy want to delete the database and start over again, but that seems to be the thing that cleared up the problem on my test server. Perhaps there is a better way of fixing it?

[DeepFreez]

I bit the bullet and deleted my cacti database and recreated everyting. It works perfectly now.

The only thing I did different was that I created the snmp query first, before adding any other graphs.

Previously I added a Generic SNMP graph first and then created the snmp data query.

[taik0]

All my snmp querys are working fine. The scripts (script/command) that doesn't appear at poller.php are perl scripts.

please insure that your system knows the path to perl. Otherwise edit your Data Input Methods to include the path to perl and then clear your poller cache.

I added the perl path and cleared poller cache and still's the same.
I've checked the rrd file and itsn't modified since it's creation.

Thanks in advance.

Please insure that php is not runing in safe_mode.

Code: Select all

;
; Safe Mode
;
safe_mode = Off

I've other perl scripts running fine under cacti (without templates).

[taik0]

I've changed at data sources the host to 'None' and now poller.php are executing the scripts.

Before the change there wasn't an entry on poller_items (on cacti DDBB), after setting the host to 'None' magically appeared.

That's great, but, why?

Thanks in advance.

Were those scripts associated with a host? You can clear it up by dumping your database and e-mailing to me. "mysqldump --user=root --password cactid > cactidump.sql".
