1. Sensor - some named number with a well-defined algorithm to calculate the value in any given moments in time. 

   Code Block
   language java
   class Sensor { String name; //EntryCount, MemoryAvailable, etc long value; //or double Collection<Tuple2<String, String>> labels; //hostName, cacheName, etc. } class TimeSensor { extends String name; //EntryCount, MemoryAvailable, etc long value; //or double Sensor { long ts; //timestamp of the last value update. Collection<Tuple2<String, String>> labels; //hostName, cacheName, etc. }

   
   

2. List - some named list of string that contains info about Ignite objects. Examples: List of caches, Transaction list, List of nodes, List of running queries, Las N queries, etc...

3. MonitoringEvent - generated when some user-defined code violates the threshold.

   Code Block
   language java
   class MonitoringEvent { MonitoringEventType type; //Event type. T info; //Event info. Type of info differs for different type of events. }

Backward compatibility is in danger with these changes.

We should consider implement implementing this IEP as Ignite 3.
