Hello Experts,

I am new to the Nagios world.
Please redirect me if I ask already asked question.
If I disable "Passive Checks" on all the services & hosts in my Nagios Core, what will be it's impact?

Passive checks are for remote devices that send nagios an update when it (the remote device) thinks it should. Like a UPS that goes onto battery power, it can send an SNMP Trap to nagios. This is what we call passive and Nagios knows about it instantly.

An active check is when nagios executes a check on it's own schedule (as per configuration directives). In the same scenario of the UPS going into battery power, if Nagios is only checking the UPS every five minutes it might not know about it for up to five minutes (not counting max retries and retry intervals).

If your checks aren't passive, there will be no impact.

Thanks for your prompt reply.
