Hi,

I have installed Nagios Fusion 2014R1.1 on a server. After installing, I restored a previously saved backup file from another Nagios Fusion server that has the same configuration (Fused Servers) that is to be used on all the Nagios Fusion servers. This seems to work, except that the system status shows a red circle for the Subsystem Poller. It thinks it is not running. However, I looked at the /usr/local/nagiosfusion/var/poller.log file and it is being updated and the ownership and permissions look correct. It looks like the last run date for the poller is the date of the backup file when I move the mouse over the red status. I do see the poller entry in the crontab and the entry is listed as a running process. Is there a way to reset the status?

Thank you

Are there any entries in /var/log/httpd/error_log that might point to a failed internal call?

The error_log file contains the following:
Sun Jan 29 03:21:02 2017] [notice] Digest: generating secret for digest authentication ...
[Sun Jan 29 03:21:02 2017] [notice] Digest: done

I noticed that after a day, one of the nagios fusion server's subsystem poller started up again and is green. However, other servers still are showing a red status w/ the old date. Is there a way to restart the poller at the command line?

The poller is just a cron job:

Code: Select all

[root@ssc66f ~]# cat /var/spool/cron/nagios
* * * * * /usr/bin/php -q /usr/local/nagiosfusion/cron/cmdsubsys.php > /usr/local/nagiosfusion/var/cmdsubsys.log 2>&1
* * * * * /usr/bin/php -q /usr/local/nagiosfusion/cron/eventman.php > /usr/local/nagiosfusion/var/eventman.log 2>&1
* * * * * /usr/bin/php -q /usr/local/nagiosfusion/cron/sysstat.php > /usr/local/nagiosfusion/var/sysstat.log 2>&1
*/5 * * * * /usr/bin/php -q /usr/local/nagiosfusion/cron/dbmaint.php > /usr/local/nagiosfusion/var/dbmaint.log 2>&1
*/5 * * * * /usr/bin/php -q /usr/local/nagiosfusion/cron/poller.php > /usr/local/nagiosfusion/var/poller.log 2>&1

Generally when I see poller issues it's because of the script taking to look to poll a server, try editing this file:

Code: Select all

/usr/local/nagiosfusion/cron/poller.php

Then for testing, set $max_time to something high (like 600 or even 900):

Code: Select all

$max_time=300

Also, please check this log for errors as well:

Code: Select all

/usr/local/nagiosfusion/var/load_url.log

Thank you
