After installing the b8 on some smaller systems i saw i problem that can be really big.
With the separation of “Check_MK” and “Check_MK Agent” service we lost the complete information about the agent/snmp execution time.
@moritz this execution time information is very crucial for bigger systems to find the problem hosts.
In the systems i tested all the hosts have only 10 to 50ms execution time and this is not true.
The execution time of the agent call and the SNMP response time must be somewhere visible.
I had bigger systems where a hand full of systems killed the performance of the complete monitoring system with very long response times.

I cannot reproduce this behavior. In fresh sites on my localhost I see timings in the expected range ~4 seconds. Am I missing something here?

It looks like that it only affects the RAW edition. That i only saw after some more tests with other small sites.

I can confirm that. It’s been introduced in b3. I’ll fix it, but I am afraid the issue will remain in b9.
