Option -e
-e, --expect=STRING
Comma-delimited list of strings, at least one of them is expected in
the first (status) line of the server response (default: HTTP/1.)
If specified skips all other status line logic (ex: 3xx, 4xx, 5xx
processing)

Increasing latency is mostly an indicator of memory leaks. The nagios core is well tested but the embedded perl interpreter in combination with badly written per plugin might cause a memory leak. Also some eventbrokers module lead to memory leaks. For example mk_livestatus should never be used with environment macros enabled. You have to monitor more then just the latency to get a feeling whats going on. Joerg -- All of the data generated in your IT infrastructure is seriously valuable. Why?

I.e. don't notify about service on this host? Thats the normal behavior! I it dose´t work, your host is not marked as "DOWN/HARD" and you have to check/fix your host check_command.
