Nagios Support Forum

What is the most efficient way to schedule downtime for the NagiosXI Server itself to perform an upgrade? Seems the last time I restarted the actual Nagios server it sent out hundreds of alerts.

What type of alerts were sent out? Are you doing any passive checks? If the nagios process is not running, (like on boot or shutdown), it should not be caching checks, etc. for alerting purposes.
