问题 I try to connect Java Mission Control (JMC) with Wildfly 16. Application server lays on Docker. I successfully connected to wildfly via jconsole, to manage it I followed steps described here. Unfortunately, I have no luck to connect via JMC. The URL which I use looks like this: service:jmx:remoting-jmx://192.168.99.100:9990 I tried to set Xbootclasspath to jboss-cli-client.jar as it was described here, but I just get Unable to connect error. I set the same jars, which are used for jconsole,

问题 Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . Java Mission Control(JMC) was announced to be handed over from Oracle to the open source community from JDK 11 onwards. However JMC is not bundled with the OpenJDK11 releases. I read that JMC will be provided as separate download here, but there are no builds to download. Also Oracle no

问题 I am experiencing some performance related issues (works ok most of the time, and from time to time there's a spike in the response time from 100ms to 4/5s with no apparent reason) in services implemented in OSB. One of the hypothesis to explain this situation is the fact that the JVM could be performing a Full GC during those spikes and we are monitoring the JVM using mission control. The admins tell me that the jvm is running with full gc's disabled, using G1GC and I can see that in the

问题 I have a Linux server where I'm running WildFly 10. I work on a Windows machine and I want to profile the remote application server. I've checked that port 9990 is enabled for access via http by accessing http://<ip>:9990/console and via JMX access from the JConsole client that comes in WildFly. For the latter, I downloaded WildFly to my machine, went to %WILDFLY_PATH%\bin\jconsole.bat , accesed through service:jmx:http-remoting-jmx://<ip>:9990 and used my credentials, it works properly. Now

问题 I'm trying to Parse JFR dump using JAVA. I followed this blog, http://hirt.se/blog/?p=446 . But these methods are deprecated now. Is there any supported parsers for JFR to JAVA? if not can you point me is it possible to retrieve data from JFR dump? 回答1: As Klara mentioned, there is no officially supported parser. Hopefully the JFR parser will be supported officially in JDK 9. For now, you can use the APIs mentioned in Hirt's blog. Don't worry about those being deprecated. :) I have

问题 I cannot connect to a remote VM using Java Mission Control . I can connect using VisualVM with relative ease. The reason I want to use Mission Control is due to a long-standing bug with VisualVM having to be restarted whenever the remote VM is restarted. Therefore, most of the leg-work involved in remote JMX connections is already in-place. I have already enhanced the configuration for Mission Control as instructed here: https://technology.first8.nl/using-mission-controle-for-remote-profiling

问题 I got to know that parsing JFR into Java can be done by unsupported parsers like JMC parser using jrockit from this. Also I figured during the flight recording there will be lot of events captured. If I want to retrieve data values from various events such as Stack trace under Events tab, Hot method under Code tab, Call tree under Code tab etc etc. How do I filter? Example image for example I was able to filter Call tree using following code as mentioned in jfr-flame-graph. final String EVENT

问题 I have a mac system. Whenever i try to open java JMC, it doesn't open. I can just see maximise, minimise and close buttons for the dialog box. The jdk version im using is jdk1.8.0_191.jdk. 回答1: This is unfortunately a bug that we recently discovered, caused by incompatibilities between old Eclipse/SWT versions and new fixes done in JDK 8u152 (backported from JDK 9) . Workaround is to run older version of JDK 8, or the latest version of JDK 7 (which includes the same version of JMC). JDK 9
