It isn't, and probably never will be. > Even if it does still work in version 3 Nagios, I would question > whether it is desireable to have Nagios not run any other checks at > all for ten whole seconds while one of these checks is run, especially > if there are quite a few of them. > Well, if you want to do a hard test on available bandwidth you really have to send a lot of data. Contaminating the result of one test with data from other tests running at the same time makes this particular test completely useless. So either scrap that check, make it non-parallellizable, or just live with the fact that the results of it may be contaminated. -- 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. ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
