This is an automated email from the ASF dual-hosted git repository.
justxuewei pushed a commit to branch main
in repository https://gitbox.apache.org/repos/asf/dubbo-go.git
The following commit(s) were added to refs/heads/main by this push:
new f6fdbfdf7 feat: add some metrics about RT (#2340)
f6fdbfdf7 is described below
commit f6fdbfdf772ad7f82ea64b8d861e4140c3fa17cb
Author: Wang Guan <wg...@gmail.com>
AuthorDate: Tue Jul 4 13:34:20 2023 +0800
feat: add some metrics about RT (#2340)
* feat: add min RT metrics
* refactor: adapt to Go 1.17 and bundle gaugeVec with syncMap
* feat: add max and sum RT metrics
* feat: avg RT metrics
* refactor: RT sum metrics
* feat: last RT metrics
* refactor: file names and method names
