Allow more than 500 Fetcher processes in Global Settings
One of our customers has a Checkmk Site that monitors about 4000 SNMP hosts, which of course uses a lot of fetchers. However, we noticed that the maximum fetcher count in the Global Settings is limited to 500. Using 500 fetchers, the fetcher usage still reaches 80% or sometimes even higher, therefore we would want to use more fetchers.
Currently, the Checkmk server uses about 24 GB of RAM using 500 fetchers. We would like to set the limit higher, as we have a lot more RAM available on our Checkmk server, therefore it would easily allow more processes.
