Good Morning

I'm new to this tool. I'v been able to install it on Tomcat 8 on my computer but I'm not able to having it working on a remote linux host

I've been following steps described on github but it seems like UI is not starting, this is glowroot output on log file

2018-05-25 11:23:14.063 INFO org.glowroot - Glowroot version: 0.10.9, built 2018-05-10 00:48:11 +0000

2018-05-25 11:23:14.065 INFO org.glowroot - Java version: 1.8.0_161

2018-05-25 11:23:16.186 INFO org.glowroot - plugins loaded: Cassandra Plugin, EJB Plugin, Elasticsearch Plugin, Executor Plugin, Grails Plugin, Hibernate Plugin, HTTP Client Plugin, Java HTTP Server Plugin, JAX-RS Plugin, Jdbc Plugin, JMS Plugin, JSF Plugin, JSP Plugin, Logger Plugin, Play Plugin, Netty Plugin, Quartz Plugin, Redis Plugin, Servlet Plugin, Spring Plugin, Struts Plugin

and actually no process is listening on port 4000

but no error is reported in glowroot.log nor in standard jvm output. Any idea?

PS: in my local log file I see on the log the line

2018-05-25 09:11:55.220 INFO org.glowroot - UI listening on 127.0.0.1:4000 (to access the UI from remote machines, change the bind address to 0.0.0.0, either in the Glowroot UI under Configuration > Web or directly in the admin.json file, and then restart JVM to take effect)

which is missing in my remote environment

Hi Francesco,

Thanks for posting!

Can you download the latest snapshot [1] and run with the additional JVM arg "-Dglowroot.debug.mainClass=true" and post back with the new glowroot log?

[1] https://oss.sonatype.org/service/local/artifact/maven/redirect?r=snapshots&g=org.glowroot&a=glowroot-agent&c=dist&e=zip&v=0.10.10-SNAPSHOT

Thanks,

Hi Trask

Thank you for your answer

I downloaded the snapshot artifact and deployed it after adding JVM arg but the output doesn't change

Here is the list of the java args in catalina.out (just in case some of them could somehow affect the behaviour of glowroot)

Hi Francesco.

I was able to repro what you are seeing (using Apache Commons Daemon jsvc to launch Tomcat).

I think this should be resolved now in the latest snapshot release https://oss.sonatype.org/service/local/artifact/maven/redirect?r=snapshots&g=org.glowroot&a=glowroot-agent&c=dist&e=zip&v=0.10.10-SNAPSHOT.

Thanks,

Hi Trask

I've just installed the last snapshot release and now I'm able to access glowroot UI.

This is the log output
