My suggestions:

[1] a. Try fping instead of the regular ping. And set the concurrency to an acceptable level. [1] b. You may also want to shorten the timeout period, if you prefer to use ping instead.

[2] Also, you have failed DNS lookups on several hosts. For faster performance, try adding the "--dns=ip" option to bbtest-net. NOTE: Use this if DNS entries for hosts do not matter much.

Hello,

I have a problem with my hobbit server, when ever a ping monitored host goes down, the bbtest column goes yellow on my hobbit server. I think it is because of the ping tests taking forever. but how can I fix this?
