zabbix_agent doesn't load config by default on CLI

[Arioch]

Hi,

I'm wondering why zabbix_agent doesn't load it's config file by default.

Default behaviour:

# zabbix_agent -t mysql.version
system.test [m|ZBX_NOTSUPPORTED]

When I run it with the config specified:

# zabbix_agent -c /etc/zabbix/zabbix_agentd.conf -t mysql.version
mysql.version                                 [t|mysql  Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1]

I've fixed it temporarily with an alias (alias zabbix_agent='zabbix_agent -c /etc/zabbix/zabbix_agentd.conf').
But I'd like to know why it doesn't load the config by default. Anybode got a clue?

$ strings /usr/local/sbin/zabbix_agent|grep zabbix_agent.conf
/etc/zabbix/zabbix_agent.conf
$

So my version reads /etc/zabbix/zabbix_agent.conf by default. Check what config file is being used by default in your case.

I see...

It results in the same behaviour again. When I disable the alias I get this error:

# zabbix_agent -t mysql.version
-bash: mysql.version: command not found

With the zabbix_agent.conf specified it works.

It -should- load zabbix_agent.conf according to strings, but it doesn't.

Do you see the difference between /etc/zabbix/zabbix_agent.conf and /etc/zabbix/zabbix_agentd.conf?

Yes I do, what kind of idiot do you take me for?

I'm just saying it doesn't load any of those two by default on my system. I've fixed it using an alias, but it's a dirty way.
Server loads it's config by default, so why shouldn't the Agent do so too?

Try the following:
- move /etc/zabbix/zabbix_agent.conf to /etc/zabbix/zabbix_agent.conf.old and run something like 'zabbix_agent -t system.uptime'. If it does really read /etc/zabbix/zabbix_agent.conf file then it should reply with 'zabbix_agent [2716]: Cannot open config file [/etc/zabbix/zabbix_agent.conf] [No such file or directory].'

If you get it then move your config file back. Start zabbix_agent again as 'zabbix_agent -t mysql.version'. (you should get an error as you had in 1st post, right?)

Now, strace/truss to monitor the execution of zabbix_agent: 'strace zabbix_agent -t mysql.version'. Check for lines like:

open("/etc/zabbix/zabbix_agent.conf", O_RDONLY) = 3
fstat64(3, {st_mode=S_IFREG|0644, st_size=5086, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7fb7000
read(3, "# This is a config file for Zabb"..., 4096) = 4096
