             Summary: Add metric framework for IoTDB
                 Key: IOTDB-1761
                 URL: https://issues.apache.org/jira/browse/IOTDB-1761
             Project: Apache IoTDB
          Issue Type: New Feature
          Components: Core/Others
            Reporter: Steve Yurong Su


The system has two characteristics
 # Define the interface of measurement collection system, including measurement collection, and measurement data exposure. You can customize your own implementation based on these interfaces.

 ## There are five kinds of measurement collection interfaces
1. Counter: can only be incremented
2. Gauge: instantaneous value, can be set and obtained
3. Rate: throughput, support 1 minute, 5 minutes, 15 minutes of throughput
4. Histogram: histogram, support multiple percentage values
5. Timer: which can be understood as histogram plus rate
 ## The measurement data exposure interface only defines the start and stop interfaces
 # At present, the implementation based on dropwizard and the implementation based on micrometer are provided. The default is the implementation of micrometer, which supports data exposure to Jmx and Prometheus
