扩大 Metric 监控信息
官网文档
Source and Scope extension for new metrics
案例：JVM Thread 减少 Metrics
批改 Thread 的定义
在 apm-protocol/apm-network/src/main/proto/language-agent/JVMMetric.proto 协定文件中笼罩 message Thread 的定义
message Thread { int64 liveCount = 1; int64 daemonCount = 2; int64 peakCount = 3; int64 deadlocked = 4; int64 monitorDeadlocked = 5; int64 newThreadCount = 7; int64 runnableThreadCount = 8; int64 blockedThreadCount = 9; int64 waitThreadCount = 10; int64 timeWaitThreadCount = 11; int64 terminatedThreadCount = 12;}从新构建 apm-network 我的项目
cd apm-protocol/apm-networkmvn clean package -DskipTests=truePS：能够装置 Protocol Buffer Editor 插件，反对 Protocol Buffer 语法
批改 agent core 中 Thread Metrics 的提供类
间接应用如下代码笼罩 org.apache.skywalking.apm.agent.core.jvm.thread.ThreadProvider 类

间接应用如下代码笼罩 org.apache.skywalking.oap.server.core.source.ServiceInstanceJVMThread 类，ServiceInstanceJVMThread继承了 Source 抽象类， Source 类是 Skywalking 中 oal 体系，资源及范畴的定义。

org.apache.skywalking.oap.server.analyzer.provider.jvm.JVMSourceDispatcher 是一个 Source 散发类，将从 agent 接管到的 JVM 相干 Metrics 拆分成对应的 Source 。例如： ServiceInstanceJVMMemory 、 ServiceInstanceJVMThread 。
批改办法org.apache.skywalking.oap.server.analyzer.provider.jvm.JVMSourceDispatcher#sendToThreadMetricProcess 为如下代码：
private void sendToThreadMetricProcess(String service, String serviceId, String serviceInstance, String serviceInstanceId, long timeBucket, Thread thread) { ServiceInstanceJVMThread serviceInstanceJVMThread = new ServiceInstanceJVMThread(); serviceInstanceJVMThread.setId(serviceInstanceId); serviceInstanceJVMThread.setName(serviceInstance); serviceInstanceJVMThread.setServiceId(serviceId); serviceInstanceJVMThread.setServiceName(service); serviceInstanceJVMThread.setLiveCount(thread.getLiveCount()); serviceInstanceJVMThread.setDaemonCount(thread.getDaemonCount()); serviceInstanceJVMThread.setPeakCount(thread.getPeakCount()); serviceInstanceJVMThread.setTimeBucket(timeBucket); serviceInstanceJVMThread.setDeadlocked(thread.getDeadlocked()); serviceInstanceJVMThread.setMonitorDeadlocked(thread.getMonitorDeadlocked()); serviceInstanceJVMThread.setNewThreadCount(thread.getNewThreadCount()); serviceInstanceJVMThread.setRunnableThreadCount(thread.getRunnableThreadCount()); serviceInstanceJVMThread.setBlockedThreadCount(thread.getBlockedThreadCount()); serviceInstanceJVMThread.setWaitThreadCount(thread.getWaitThreadCount()); serviceInstanceJVMThread.setTimeWaitThreadCount(thread.getTimeWaitThreadCount()); serviceInstanceJVMThread.setTerminatedThreadCount(thread.getTerminatedThreadCount()); sourceReceiver.receive(serviceInstanceJVMThread); }在 java-agent.oal 减少相干指标
在oap-server/server-bootstrap/src/main/resources/oal/java-agent.oal 增加如下语句
// 参考oal语法instance_jvm_thread_deadlocked = from(ServiceInstanceJVMThread.deadlocked).longAvg();instance_jvm_thread_monitor_deadlocked = from(ServiceInstanceJVMThread.monitorDeadlocked).longAvg();instance_jvm_thread_new_thread_count = from(ServiceInstanceJVMThread.newThreadCount).longAvg();instance_jvm_thread_runnable_thread_count = from(ServiceInstanceJVMThread.runnableThreadCount).longAvg();instance_jvm_thread_blocked_thread_count = from(ServiceInstanceJVMThread.blockedThreadCount).longAvg();instance_jvm_thread_wait_thread_count = from(ServiceInstanceJVMThread.waitThreadCount).longAvg();instance_jvm_thread_time_wait_thread_count = from(ServiceInstanceJVMThread.timeWaitThreadCount).longAvg();instance_jvm_thread_terminated_thread_count = from(ServiceInstanceJVMThread.terminatedThreadCount).longAvg();批改 apm.yml
在 oap-server/server-bootstrap/src/main/resources/ui-initialized-templates/apm.yml 文件的 APM 面板下的 Instance 项减少如下配置

总结
Metric 如何扩大，网上基本上没案例，都是看官网文档和源码理解。对应这种十分热门的开源我的项目，还是看官网文档和源码更稳。
