only rest，how about the rest？

[turboFei]

kyuubi.rest.connection.opend

Do you mean kyuubi.rest.opend instead of kyuubi.rest.connection.opend?

[yaooqinn]

oh.. i mean only recording the REST frontends? what about the rest frontends

[turboFei]

The REST frontends seems special, because it is not interactive connection.

and now there is metrics(THRIFT_HTTP_CONN) for KyuubiTHttpFrontendService.

And there is no metrics for below frontends:

• thrift binary
• mysql
• REST

The kyuubi.connection.opened is for all frontends.

we need an umbrella then to support all of them, not just for rest, wdyt?
