Zabbix server is running = no

[leonidasklein]

Hi I'm implementing a zabbix server on the corporation I work. All tests i have made with zabbix on VMs have worked. But, now I'm configuring it on a real host and on the dashboard It keeps showing that zabbix server is not working. I already have checked server log and apparently there is no error message.

Can someone give me a hande trying to fix this? Thank you.

Hi, i have found a workwround for this problem. If i disable SELinux the frontend is cabable of detecting zabbix server. I don't want to keep SELinux disabled, do you have any other idea?

Thank you.

you must create a policy for zabbix..

[leonidasklein]

Sorry, but i'm relatively new on linux and zabbix world. How can I create such policy?

Thank you.

after disabling SELinux the dashboard shows that zabbix server is running. But there is a trigger that keeps firing saying that zabbix server is NOT running.

Please see attached.

any update on this? my dashboard shows the same thing, zabbix server not running.

[Colttt]

ok.. look at the log-files.. and change the logging-level to 4..

[pc99096]

ok and what exactly should i be looking for? do you have the name of the procedure or something?
i went through the log file and found nothing interesting so far.

to get rid of this status, i simply removed the whole row on the dashboard:

$table->addRow(array(S_ZABBIX_SERVER_IS_RUNNING,new CSpan($status['zabbix_server'], ($status['zabbix_server'] == S_YES ? 'off' : 'on')),
isset($ZBX_SERVER, $ZBX_SERVER_PORT) ? $ZBX_SERVER.':'.$ZBX_SERVER_PORT : S_ZABBIX_SERVER_IP_OR_PORT_IS_NOT_SET
));



in include/blocks.inc.php

Got ir working

Hey! sorry for the delay.

I got it working. I noticed that as default zabbix search for zabbix-server process. But I installed zabbix through EPEL repository on CentOS6. Installing this way has created a zabbix-server-mysql process instead of the zabbix-server. I just changed the Item to monitor zabbix-server-mysql process and all is running smoothly now

that's fine, but i'm afraid it's not related to the original problem.
the Yes/No value in the first row of the Status of Zabbix table on Dashboard is determined from the
$checkport = fsockopen($ZBX_SERVER, $ZBX_SERVER_PORT, $errnum, $errstr, 2);
function in include/config.inc.php

SeLinux

Disabling SELinux solved the Yes/No Problem for me.

[pc99096]

ok but what if disabling selinux is not very desired? i was expecting that somebody has/had experience implementing selinux zabbix policy

[leonidasklein]

SELinux

Unfortunatelly that's the only way I was able to solve this issue. I hope somebody can help us on this too.
