Zabbix Sender

[jsosic]

From version 1.6 of Zabbix, zabbix_sender is changed, and it doesn't read config file from the command line anymore...

We've got a whole bunch of plugins with hardcoded calls to zabbix_sender, and now we can't migrate them to zabbix agents 1.6.

I've strace-ed zabbix_sender, and there is no open call for anything I put after -c parameter...

Is this a bug?!

Look at this:

# /usr/sbin/zabbix_sender -z myserver.mydomain.com -c /etc/zabbix/zabbix_agentd.conf -k mysql.bytesreceived -o 45940
Info from server: "Processed 1 Failed 0 Total 1 Seconds spent 0.004097"
sent: 1; skipped: 0; total: 1

And this time without '-z':

# /usr/sbin/zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -k mysql.bytesreceived -o 45940
usage: zabbix_sender [-Vhv] {[-zpsI] -ko | [-zpI] -i <file>} [-c <file>]

And now with strace, without '-z':

# strace /usr/sbin/zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -k mysql.bytesreceived -o 45940 2>&1 | grep open | grep etc
open("/etc/ld.so.cache", O_RDONLY)      = 3

Why is zabbix_sender ignoring -c command line option?!?!

It's very interesting to note that if the sender iz called with both '-z' and '-c' options, it then opens config file....

I'll try to write a patch.

OK I've got it.
Problem is that function that parses options from command line has wrong check... It only checks if ZABBIX_SERVER is on the command line ('-z' argument), and if it's not, it exits with error. That is not the correct behaviour because ZABBIX_SERVER can be stated in the config file too. Here is the patch:

+       if((ZABBIX_SERVER == NULL) && (CONFIG_FILE == NULL))
        {   
                usage();
                exit(FAIL);

I guess that this is not enough, and that Server=something parameter must be checked within the config file too. But this is enough for me and my organization, and I'm building the RPM's with this patch included.

I hope that you fix this soon.

Thank you.

Alexei or somebody, are you interested that I write another patch for zabbix_sender, that checks for Server= directive in zabbix_agentd.conf ? Where can I apply patches except on this forums?

Bump

+1 *bump bump*

Same problem in latest version 1.6.2.

Actually I found that:
zabbix_sender -z -k asterisk.status -o 0 -c /etc/zabbix/zabbix_agentd.conf

Does not work - it still uses the -z parameter even if nothing is specified.

Whereas:
zabbix_sender -z zabbix.my.net -k asterisk.status -o 0 -c /etc/zabbix/zabbix_agentd.conf

Does work, but is still not optimal - since it is overriding the configuration file option.

I don't get it, I even wrote a patch and nobody cares

Where's zabbix bugzilla, I'll try and open new ticket there...

Thank you very much. This one is registered as ZBX-677.

Hi

see my patch here.
And you should post your patch in that group, too. or use mine

It will allow to omit the now mandatory "-z ZABBIX-Server".
That's all you have to change.
Read the thread and you'll see my thoughts.

The patch was initially for 1.6 but works with 1.6.1 and should apply to 1.6.2, too.

Addition: Your patch is included in zabbix 1.6 R6679.

HTH,

Norbert.

I've seen it, issue ZBX-677 is resolved...

Now I should write a patch for a zabbix_agentd that doesn't read all the config files from conf.d dir for some reason...
