proc.num on FreeBSD 7 (Zabbix 1.5.3 b)

[Lufa]

Hi!
I have just upgraded Zabbix server and agent to 1.5.3b on my FreeBSD 7.0 and founded that many items are not working with the "Not supported by ZABBIX agent" error.

For example proc.num item. But, from console it works just fine:

# /usr/local/sbin/zabbix_agentd -t "proc.num"
proc.num[]                                    [u|237]
# /usr/local/sbin/zabbix_agentd -t "proc.num[httpd]"
proc.num[httpd]                               [u|12]

Why it is not working for Zabbix? Is it normal for current beta?
Thank you.

P.S.
Fresh install did not help.

This should work in 1.5.x!

But not 1.5.3 beta?

The FreeBSD agent is still based on the layout of the /proc filesystem
in use by FreeBSD 4.x/5.x

I modified the agent to either use the FreeBSD 6.x /proc layout
(completely different to the older one) or the libkvm interface.
Either has disadvantages (/proc doesn't show everything to
a usual zabbix user, libkvm needs read access to /dev/kmem), so I'm not sure which one is better, yet.

It might have changed in the latest SVN versions.
I didn't have time to check them for modifications.

P.S. I'll do the check tonight on my home machine againt R5900 (checked out yesterday).

Check on FreeBSD6.1

Hi

I checked the source code yesterday.
Indeed it was changed to use "sysctl" now.
And in the comments it states "Checked on 7.0".

However, on my FreeBSD 6.1 laptop it doesn't work that well.
It shows the number of some processes just fine, e.g.
sshd, ntpd, zabbix_agentd, etc.
But my own processes, e.g. nautilus, audacity, etc. always show up with
a count of 4 although just one is running.
All tests were done with a command like

zabbix_get -s 127.0.0.1 -k 'proc.num[nautilus]'

It could be a problem on 6.1, I'll check it on 7.0 tonight.

I don't have a ZABBIX-Server running, so I can't check the
ZABBIX agent active mode.

Regards

Norbert.

Seems to be worked on my FreeBSD 7 and new Zabbix 1.5.4!

But not on FreeBSD 6.2, despite working welll from console...

Solved

OK. All I needed to do is unlunk the host from my FreeBSD templated, save it and link it back again!

May be I am upgrading Zabbix from nightly builds too often?

Thanks!!!

Just thought i would chime in here...
Looking at my output for proc.num[] the number reported is alot higher then the actual process listed from ps and top.

Looking at /src/libs/zbxsysinfo/freebsd/proc.c i can see that KERN_PROC_ALL is being used to display the results which will return all processes and kernel visible threads.

As im not interested in proc+threads, i changed the two entries to KERN_PROC_PROC which will return all processes, without threads.

thought this may help someone else...

Thanks for your patch!

Thanks!
Problems with threads is fixed in rev. 6109.
