Help with basic zabbix config.

I have zabbix (2.0.6) installed and running on Centos 6.4. I have downloaded the zabbix agent and installed it to one of my dev servers. No matter what I do, I can not get it to show up as being monitored in host configuration. I have turned off (disabled) the centos firewall on both machines. On the zabbix server I can telnet to 10050 and 10051 showing the service is listening on those ports. On the server I am trying to monitor, I cannot telent to localhost 10051 no matter what I do. What do I need to do to fix this? I have tried everything I can think of. I know that it is not listening on 10051 (10050 works). I know I am missing something simple here but for the life of me I dont know what.

Did you build your own zabbix packages, or did you install from e.g. EPEL?

Either way, there should be a configuration file that zabbix_agentd will read to determine a few important parameters (like what server(s) can request items, etc.). In addition, the config file will specify where the zabbix_agentd will *log*.

So, find the configuration file. It's probably in /etc/zabbix/zabbix_agentd.conf, or perhaps just /etc/zabbix_agentd.conf. Things from
the configuration file that I typically change are:

# make sure /var/run/zabbix exists and is owned & writeable by the zabbix
# user
PidFile=/var/run/zabbix/zabbix_agentd.pid
# ditto for /var/log/zabbix
LogFile=/var/log/zabbix/zabbix_agentd.log

# YOU MUST SET THIS.  The default setting (127.0.0.1) means
# zabbix_agentd will only accept connections from localhost.
Server=your_zabbix_server_here

# if you're not using "active" monitoring (where Zabbix's definition of active
# means the client sends unsolicited data to the server), then you should
# comment out the "ServerActive" setting.
# otherwise, it should be set to the same thing that Server is set to.
ServerActive=

#
# if Hostname is uncommented, I recommend you COMMENT IT OUT.  It's
# a poor default setting to set it via the config file on Linux.  Read the
# comments for Hostname and HostnameItem for more info.

Once you've verified these settings are appropriate for your environment, then you should

- restart the zabbix_agentd
- verify with "ps" on the client that it's running
- verify with netstat or lsof that it's listening on the network
- review any entries in the zabbix_agentd.log file.

Once you've done that, try connecting manually from the Zabbix server:

- run "zabbix_get" as the zabbix user, e.g.

  sudo -u zabbix /usr/local/sbin/zabbix_get \
         -s your_client_name_here -p 10050 \
         -k 'system.cpu.load[percpu,avg1]'

If it generates reasonable output, it means the zabbix server can connect to the agent running on the client you specified and get the 1 minute load average.

I managed to fumble around and get it working. Thanks for the great post.. Good info in there for troubleshooting. Save and sent to evernote!
