I have some. I have just implemented some Hazelcast Service monitoring for Java in Dynatrace Managed but can be usable for Appmon too. By this method you can monitor the requests and gives you feedback about the response time from client view but does not connect the purePath to Hazelcast server.
First you have to find out which caching feature is used by Developers.
For example: If they use ICache you find the interface definition and implemented class on this website (version 3.6):
find ICache class and check the implementing classes. For example ClientCacheProxy.
Define a method sensor for class com.hazelcast.client.cache.impl.ClientCacheProxy for minimum put and get methods. (or for ALL to find the most important ones)
Than make hot sensor placement or restart the JVM if not possible. Than you can create Methods/Time measure and BT based this sensor.
This method is basically the some for other hazelcast features.
