扩展 Metric 监控信息
官方文档
Source and Scope extension for new metrics
案例：JVM Thread 增加 Metrics
修改 Thread 的定义
在 apm-protocol/apm-network/src/main/proto/language-agent/JVMMetric.proto 协议文件中覆盖 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;
}
重新构建 apm-network 项目
cd apm-protocol/apm-network
mvn clean package -DskipTests=true
PS：可以安装 Protocol Buffer Editor 插件，支持 Protocol Buffer 语法
修改 agent core 中 Thread Metrics 的提供类
直接使用如下代码覆盖 org.apache.skywalking.apm.agent.core.jvm.thread.ThreadProvider 类

修改 ServiceInstanceJVMThread
直接使用如下代码覆盖 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，资源及范围的定义。

修改 JVMSourceDispatcher
org.apache.skywalking.oap.server.analyzer.provider.jvm.JVMSourceDispatcher 是一个 Source 分发类，将从 agent 接收到的 JVM 相关 Metrics 拆分成对应的 Source 。例如： ServiceInstanceJVMMemory 、 ServiceInstanceJVMThread 。
修改方法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 增加相关指标
在oap-server/server-bootstrap/src/main/resources/oal/java-agent.oal 添加如下语句
// 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();
修改 apm.yml
在 oap-server/server-bootstrap/src/main/resources/ui-initialized-templates/apm.yml 文件的 APM 面板下的 Instance 项增加如下配置
{
"width": 3,
"title": "JVM Thread Count (Java Service)",
"height": "250",
"entityType": "ServiceInstance",
"independentSelector": false,
"metricType": "REGULAR_VALUE",
"queryMetricType": "readMetricsValues",
"chartType": "ChartLine",
"metricName": "instance_jvm_thread_live_count, instance_jvm_thread_daemon_count, instance_jvm_thread_peak_count,instance_jvm_thread_deadlocked,instance_jvm_thread_monitor_deadlocked"
},
{
"width": 3,
"title": "JVM Thread State Count (Java Service)",
"height": "250",

"queryMetricType": "readMetricsValues",
"chartType": "ChartBar"
}
如果不清楚添加位置，可以直接使用如下配置，覆盖 oap-server/server-bootstrap/src/main/resources/ui-initialized-templates/apm.yml
