[GitHub] [incubator-pegasus] empiredan opened a new issue, #1336: Feature(new_metrics): migrate replica-level metrics for write service
empiredan opened a new issue, #1336:
URL: https://github.com/apache/incubator-pegasus/issues/1336
As is described in https://github.com/apache/incubator-pegasus/issues/1326, since both `pegasus_server_write` and `pegasus_write_service` are derived from `replica_base`, their replica-level metrics can be attached directly to *replica* entity. `pegasus_write_service` is one of the members of `pegasus_server_write`.
Following metrics are the members of `pegasus_server_write` ([pegasus_server_write.cpp](https://github.com/apache/incubator-pegasus/blob/master/src/server/pegasus_server_write.cpp)). Their variables in current source files and new types/computations in new framework are listed as below:
| Variables | Types/Computations |
| :-------: | :------------------: |
| _pfc_recent_corrupt_write_count | increase(Counter) |

@empiredan It would be better to describe the relationship between old metric names and the new ones, then users know how to change their monitor tools.

OK, I'll add both old and new names into the table. Also, I'll summarize all the changes into a big table.
