This is one of the big reasons I stopped using NDOUtils - the broker would regularly block the Nagios process. So yes, you're correct - your NDOUtils broker is blocking, and nothing is happening during these periods of maintenance. That, and the check latency. With NDOUtils, I couldn't let my Nagios daemons run a full week without restarting them or the check latencies would shoot through the roof (that's a full restart, not a reload). -- "The problem with quotes on the internet is that it's very hard to verify their authenticity." -- Abraham Lincoln ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
