Deactivate

[mananatmacys]

Can someone explain what does deactivate mean? I'm aware of what it does. I am wondering if it means that the host is removed from active hosts list or does it mean that alert traps are not being sent to that host?

Traps are usually not sent by nagios, but from a remote server/device to nagios. Deactivating an object means that this object will be removed from the actual configs in Nagios XI. It is almost the same as deleting the object, however with deactivating it, you would have an option to activate it later if you wish. On the other hand, if you deleted it, you would need to re-add the object (recreate it from scratch). Let us know if you have any further questions.

Then is disabling active check for host same as deactivate host?

[lmiltchev]

No, they are different. When you deactivate a host, the object is removed from the configs. When you disable active checks, this means that they won't be run by nagios.

If you had a host, that was monitored passively, the checks would be initiated and performed by an external application. Disabling the active checks won't affect this host.

If you had a host that was monitored actively, the checks would be initiated and run by nagios on a regularly scheduled basis. By disabling the active check on this host, you would basically stop monitoring it.
