There is. Nagios 3.4 will be a single-threaded and event-driven application that sports an I/O-broker and vastly improved check performance. In essence, we've removed 2 fork() calls, 4 disk searches, 2 filewrites and 2 filereads from each check being performed. There's also a fixed usage of the current scheduling queue implementation which turns scheduling new checks from its current O(n) behaviour to O(1). This will provide a huge benefit for large installations, and combined with the worker process code we're currently seeing a 12-fold increase in the amount of checks Nagios can execute, but it's still too early to tell what other things are affected. The external command pipe might be a bottleneck if one uses large amounts of passive checks, for example. It's currently in late alpha, so beta releases should be available in a month or so. -- Andreas Ericsson [email protected] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. ------------------------------------------------------------------------------ Better than sec?
