how to adjust timeout value for HTTP/SSH tests ?

hi, there, Once or twice a day, I have a server whose HTTP/SSH will go red then recovered within a minute. For a few times, it recovered at next run instead of within the same run. The somewhat sluggish response from HTTP/SSH servers could be due to the load on the system at the time.

For this particular server, I just want to know the service is responding and not all so concerned about its performance at this point. The actual status message says the server times out at 10.79s.

1. any way I can set this timeout value to 30s or 60s
2. it seems there's a 2nd probe for each test within a test run. Can it be set to go red only failed two probes in a row? I assume the 2nd probe using longer timeout.
