hi, I would like to know what is the maximum number of servers that can be connected to the Enterprise Manager. When I tried to connect to >60 servers (irrespective of windows OS /Linux OS) I could see some of the servers are not showing up in the " Investigator "and even though when servers are showing up not all the metrics are shown. So please advise whether to reduce the server count or Do I need to tune configuration inside the APM installation path. Thanks in advance!
The number of agents per EM has been covered in this Community previously. Some of these include
Historical metrics limit
Please review and let me know if there are any questions
You might need to increase:
However, this will impact the EM and/or cluster performance.
I suggest you to review the additional suggestions I included in the below thread:

As Hal stated, this has been covered extensively. Also you may want to review our sizing and performance guide. Please keep in mind that every environment is different.
