Recently, we have frequent errors regarding "Agent Metric Registration Limit Reached". I searched the kbs and Google for possible answers and came up with this. We are trying to get much information regarding this error so that we can better plan on our next steps. With this, we have few questions and I hope you could help us with these:
I hope you could help us with these. Thank you very much!
I think the only way may be to recursively call the API to retrieve the hierarchy as defined here: https://docs.appdynamics.com/display/PRO45/Metric+and+Snapshot+API
Metric Registration increase as there is an increase in Auto Detected BTs or Auto detected Backend.
So try to see, whether the BT Count count exceeded 200 or not.
If Yes, then 1st try to work on reducing No. of Auto Discovered BTs,
for which you can change the configuration in "Automatic Transaction Discovery Rule"
e.g. Reducing segments of the URL for Servlet BT
or Disabling unwanted types of BTs and /or Backends
I hope this will help.

Hi @Manish .Upadhye,
Thank you for sharing that helpful info. @Bryan James.Ilaga, I know you asked this question a while ago. If this topic is still of any interest to you, please check out the reply from Manish.

We are seeing agent metric registration limit issue only on two servers where it only discovers 10 transactions. Rather than on other nodes, it discovers more than 100 transactions.
Will transactions generated from other servers also have an impact.
Other nodes are not giving any such warning
Yes, transactions auto-generated / detected from other nodes / servers /Tiers also contribute to total BT count. As There is default limit of 200 BTs, on BT detection across particular Application.
So try to see, whether the existing BT Count exceeded 200 or not (across Application).
