Title: Service discovery page: Active checks were not correctly shown in specific cases
Component: WATO
Level: 1
Class: Bug fix
Version: 1.6.0i1
It could happen that some active checks were not correctly shown in the tables
"active checks" or "disabled active checks". This was caused by specific
disabled services rules. For example when using this two rules:
1. Enable all services starting with "HTTP"
2. Disable all services
In this situation the HTTP service was not displayed on the discovery page.

Title: Net-SNMP: Add some patch trying to fix SNMPv3 communication in some cases
Component: Other Components
Level: 1
Class: Bug fix
Version: 1.6.0i1
When using SNMPv3 communication issues with some devices may occur. From the user point of
view timeouts are reported by Check_MK originating from Net-SNMP not receiving a valid response.
This kind of issue is related to a broken negotiation (related to the maximum message size) between
the monitoring and the monitored device.

Title: ps: The linux ps check CPU utilization calculation changed since 1.4.0p27
Component: Checks & agents
Level: 1
Class: Bug fix
Version: 1.6.0i1
The calculation of the CPU utilization of processes on linux systems was not taking the number
of CPU cores into account for a long time. This results in CPU utilizations reported with more
than 100%, up to 100%*CPU-cores. For example in case 3 processes use 3 of 6 cores at 100%, this
resulted in a usage of 300%.
The intention of the change in 1.4.0p27 was to make the windows and linux ps checks both take
the number of CPU cores into account and cap the usage at 100%. The problem with this change is
that all possibly existing thresholds that have been configured for the old scheme will not
work anymore with the new scheme.
We have now reverted the changes version 1.4.0p27 introduced to get the old behavior back.
In a future release, we will finally make the switch to the new scheme. But this will be done
in a compatible way where the already configured thresholds will still work.
