Yes, it's called nagios-3 (alpha/CVS only at the moment) ;). > Let me tell you further, who are interested and have time: > I have set up Nagios to check only up/down state for about 300 hosts. > However, it could not finish checks in desired time period. Even, my host > check latency was about 400 secs!. You shouldn't be using scheduled host checks in any version prior to nagios-3 except for exceptional circumstances. It sounds like you are using them for normal checks. > I have noticed host checks were unable to be done in parallel.

Nagios is very service-centric. Nagios monitors services first and foremost. Hosts will only be checked when a service on the host fails. If a service is up, then the host _must_ be up. Nagios-3 introduces parallelized host checks and benefits of doing regular host checks in addition to service checks but services are still the primary focus IMHO. > But, It is impossible for me to say Nagios to check a host five times with > "1 minute delays" more to decide if a host is down. It checks host 5 times > eventually with 10 seconds delay. Nothing to do with it. That's correct, at least for nagios-2 and prior. -- Marc ------------------------------------------------------------------------- Take Surveys. Earn Cash.
