I am new to PagerDuty and have a question on Whitelisting.
In the Whitelisting docs it says there are 3 sets of IPs that need to be Whitelisted. *i.e. Events, REST and Webhooks.
But, it doesn’t mention which of those URLs/IP lists are absolutley necessary for the Nagios/PagerDuty two-way integration. So, I was wondering which of those 3 are Required and which are Optional (*if any).?
I was confused as to if all three of those are actually needed…? The “Events” explanation makes sense, because it specifically says its for triggering, acknowledging, and resolving incidents, which I believe is for outbound connections from our Nagios server to the events.pagerduty.com URL. And Webhooks would be the opposite. But, I’m a little confused on the REST API and its purpose.
I’m not sure. But, it sounds like only Events (*Outbound from Nagios to PagerDuty) and Webhooks (*Inbound from PagerDuty to Nagios) are required?
Thanks in Advance,
