Report the agent version to OAP
Report the agent version to OAP

Currently, the agent version used by all applications cannot be sensed, It is beneficial for agent developers to diagnose some problems, and help us find which applications haven't upgraded the agent. I use git-commit-id-maven-plugin to generate the agent version, and report it to OAP when the agent starts.

The agent version is consist of three parts:

build version: the maven project version

short commit id: git commit short id

date: build date.

Here is the agent log from my local env with this feature:

INFO 2022-11-24 09:51:32.331 main InstanceJsonPropertiesUtil : SkyWalking agent version: 8.14.0-SNAPSHOT-add2bc4-221124

And the OAP server could show this agent version, too. What do you think of this feature? Any suggestions? @wu-sheng

Support collecting dubbo thread pool metrics

Inspired by the implementation of untow_thread_pool at issue#8433

Now the skywalking-javaagent could collect the Dubbo thread pool metrics. I tested it with dubbo-2.6.9 and dubbo-2.7.4.1 and ran it in our production environment with hundreds of applications, it works well.

Dubbo could use telnet to get the thread pool status, this meter plugin is related to this telnet implementation.

$ telnet localhost 20880                 
Trying ::1...
Connected to localhost.
Escape character is '^]'.

dubbo>status -l
+------------+--------+--------------------------------------------------------+
| resource   | status | message                                                |
+------------+--------+--------------------------------------------------------+
| threadpool | OK     | Pool status:OK, max:200, core:200, largest:3, active:1, task:3, service port: 20880 |
| load       | OK     | load:2.60595703125,cpu:12                              |
| memory     | OK     | max:3641M,total:1294M,used:481M,free:813M              |
| registry   | OK     | 127.0.0.1:2181(connected)                            |
| server     | OK     | /127.0.0.1:20880(clients:1)                         |

+------------+--------+--------------------------------------------------------+

Please take a look. Also, cause the e2e test is friendly for the trace plugin, rather than the meter plugin. There is no test code with this PR, I'm willing to add test code if there are some guidelines.

[x] Update the documentation to include this new feature.
