Core Config Manager Daily Snapshots

Hi,
Does Core Config Manager take an automatic daily snapshot?
I'm not sure if it's normal behaviour or a sign of an issue. I haven't been able to find any information on it.
I'm seeing snapshots that seem to occur daily around the same time but not instigated by a user applying changes.
Regards,
Andy

Hi Andy,
Besides the daily snapshot running on a cron schedule, it should take a snapshot every time configuration is applied.
Let's trying running the tail command below and then apply configuration to capture debug output.
Code: Select all
tail -f /usr/local/nagiosxi/var/cmdsubsys.log

Hi,
We do see a snapshot being taken each time configuration is applied.
Are you saying there is a daily snapshot running on a cron schedule? If so, is there a way to see how that is configured?

Hi,
It's the nom.php scrit and it runs on a cron job, see /etc/cron.d/nagiosxi.
Code: Select all
[root@localhost cron.d]# cat nagiosxi
# /etc/cron.d/nagiosxi: crontab fragment for nagiosxi

There's an interval, nom_checkpoint_interval, in config.inc.php that specifies how often it's going to take a snapshot.
Code: Select all
$cfg['component_info'] = array(
"nagioscore" => array(
"root_dir" => "/usr/local/nagios",
"cgi_dir" => "/usr/local/nagios/sbin",
"import_dir" => "/usr/local/nagios/etc/import",
"static_dir" => "/usr/local/nagios/etc/static",
"plugin_dir" => "/usr/local/nagios/libexec",
"cgi_config_file" => "/usr/local/nagios/etc/cgi.cfg",
"cmd_file" => "/usr/local/nagios/var/rw/nagios.cmd",
"log_file" => "/usr/local/nagios/var/nagios.log",
"nom_checkpoint_interval" => 1440, // time (in minutes) between nom checkpoints
Hope that helps answer your questions. If this is not running, let's check the cron service and logs.
Code: Select all
systemctl status crond
tail -n 100 /var/log/cron

Thank you. That's exactly the information I needed. It is running as expected.

Excellent! We'll close this one out but feel free to open another post if you have future issues.
Thank you for using Nagios.
