Some logs are found for meta server as follows: ``` F2022-09-09 17:02:17.184 (1662714137184230445 11231) meta.meta_state0.0202000700000001: server_state.cpp:895:on_config_sync(): assertion expression: false F2022-09-09 17:02:17.184 (1662714137184247617 11231) meta.meta_state0.0202000700000001: server_state.cpp:895:on_config_sync(): gpid({}) on node({}) is not...
This PR is for https://github.com/apache/incubator-pegasus/issues/1116. This PR introduces data sink to collect snapshot from each metric periodically. The base data sink is actually an abstract class that has interfaces needed...
This is the sub-issue of https://github.com/apache/incubator-pegasus/issues/922. As a part of the framework of new metrics, the data sink, just as its name implies, is the destination where the metric data...
# 1. Prometheus metrics of old framework In the old framework, all the metrics have the identical metric labels. The only difference is that for those metrics which have no...

We could use [thrift-maven-plugin](https://mvnrepository.com/artifact/org.apache.thrift/thrift-maven-plugin) to generate thrift sources instead of scripts, just like what [parquet](thrift-maven-plugin) has done.
According to https://github.com/apache/incubator-pegasus/issues/1206, metrics would be fetched by RESTful API. In Pegasus, some components require access to http services. For example, Pegasus shell needs to access metrics. Thus, while providing...

The replica-level entity can be bound to [replica_base](https://github.com/apache/incubator-pegasus/blob/master/src/replica/replica_base.h), since all of the classes (`pegasus_server_impl`, `replica`, etc., see classes in following sub-tasks) that hold replica-level metrics are derived from `replica_base`; Moreover,...
