    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!

    Hi:

    The number of agents per EM has been covered in this Community previously. Some of these include

    https://communities.ca.com/thread/241775060

    Historical metrics limit 

    Among others

     

    Please review and let me know if there are any questions

     

    Thanks

    Hi Yuvaraaj,

    You might need to increase:

     

    introscope.enterprisemanager.agent.metrics.limit

    introscope.enterprisemanager.metrics.live.limit

    introscope.enterprisemanager.metrics.historical.limit

     

    However, this will impact the EM and/or cluster performance.

    I suggest you to review the additional suggestions I included in the below thread:

     

    Unable to update load balancing for collector 

     

    Regards,

    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.

    The APM Status Console - CA Application Performance Management - 10.5 - CA Technologies Documentation 

    To check whether the metric limits/thresholds have been reached, may I suggest checking the Status console as depicted above?
