Nobody put it together, so I made it by hitting ManagementFactory.getPlatformMBeanServer (). For the time being, I'm taking the CPU, memory, GC times and time.
I think it can be used when creating a JVM application that is supposed to collect performance counters with Application Insights.
Since it will be either PS / CMS / G1 with the GC option, we are sorting it out. However, at the moment, it seems that counters that do not exist are not collected in some cases, so I think that you can throw in with this setting.
displayName will be the name when searching with Analytics, so you can rewrite it appropriately.

By the way, if useBuiltIn in XML is set to False, Metrics around here will not take the ones with BuiltIn. (Processing location )
The following is a good idea for detailed XML settings. The default interval is 60 seconds, so if you want to make it shorter, you need to write the setting.
https://github.com/microsoft/ApplicationInsights-Java/wiki/ApplicationInsights.XML
Also, some values such as java.lang: type = GarbageCollector, name = PS Mark Sweep cannot be acquired. The following is the issue.
Cannot fetch jmx counter for GC with Java SDK agent #952
(Addition so far)
Code when hitting ManagementFactory.getPlatformMBeanServer () to make the above list
import java.lang.management.ManagementFactory;
import java.util.Set;
import javax.management.Attribute;
import javax.management.AttributeNotFoundException;
import javax.management.InstanceNotFoundException;
import javax.management.IntrospectionException;
import javax.management.MBeanAttributeInfo;
import javax.management.MBeanException;
import javax.management.MBeanInfo;
import javax.management.MBeanServer;
import javax.management.ObjectName;
import javax.management.ReflectionException;
public class Test {
public static void main(String[] s)
throws ReflectionException, IntrospectionException, InstanceNotFoundException, AttributeNotFoundException,
MBeanException {
MBeanServer server = ManagementFactory.getPlatformMBeanServer();
Set<ObjectName> names = server.queryNames(null, null);
for (ObjectName name : names) {
System.out.println(name);
MBeanInfo beanInfo = server.getMBeanInfo(name);
for (MBeanAttributeInfo attrInfo : beanInfo.getAttributes()) {
try {
Object attrObject = server.getAttribute(name, attrInfo.getName());
if (attrObject instanceof Attribute) {
Attribute attr = (Attribute) attrObject;
Object attrValueObject = ((Attribute) attrObject).getValue();
System.out.printf(" attribute: %s = %s\n", attrInfo.getName(), attrValueObject);
} else {
System.out.printf(" attribute: %s = %s\n", attrInfo.getName(), attrObject);
}
} catch (Exception e) {
System.out.printf(" attribute: %s = %s\n", attrInfo.getName(), "???");
}
}
}
}
}
The composite attribute is like taking the key-value of contents. (I didn't know how to get the key value, but I can see it with toString) For example, memory is the case, and the output is as follows.
java.lang:type=MemoryPool,name=Metaspace
~ Omitted ~
attribute: Usage = javax.management.openmbean.CompositeDataSupport(compositeType=javax.management.openmbean.CompositeType(name=java.lang.management.MemoryUsage,items=((itemName=committed,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=init,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=max,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=used,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)))),contents={committed=6029312, init=0, max=-1, used=5663360})
You can see the contents at the back.
In this case, the Attribute name is "Usage" in JMX and "used" in contents, but when writing in XML of Application Insights, it is like adding type =" composite " attribute to attribute as ʻUsage.used` Become.
