问题
Usually I see all these tabs in VisualVM for locally running Java programs:
However, I have one local program which is currently only showing me Overview and Monitor (even though it usually shows all those shown above):
Also interesting is that VisualVM itself doesn't present the Profile tab:
All three of the programs shown are running with the same JVM with the same Java Home.
What controls which tabs are shown for a particular program? How can I get them all back for my program showing just Overview and Monitor?
I have Visual VM 1.3.5 (latest at this date) and JDK 1.7.0_17.

I found that this was the issue of usage of wrong JDK version. In my case my application was running on 64bit JDK and I started VisualVM from 32bit JDK. After starting VisualVM from the same JDK on which my application is running, everything was fine. Hope it will help you.

You might need to enable jmx ports on your app. Try adding these switches to your VM and see if the tabs appear again:
-Dcom.sun.management.jmxremote.port=6789 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

I just remove ~/.visualvm and rerun, See https://java.net/jira/browse/VISUALVM-598

What worked for me was specifying the "Start profiling from" classes. If I left this blank, I didn't get the profiler tab. When I specified it, I did. I should probably note that this was a web application running under Tomcat, so I specified org.apache.catalina.startup.** as the starting class.

Check that proxy is disabled if you are running VisualVM for local application

I had a similar problem with missing profiler tab in VisualVM. I'm using Oracle JDK 1.8 and want to profile web application running on Tomcat 8 (JPA, Spring, Hibernate, Vaadin, etc).
I tried all above-mentioned solutions and many others found on the internet, but unfortunately, none of them solved missing profiler tab issue.
So I switched to Java Mission Control profiling tool (JMC + Flight Recorder) which is a part of standard Oracle JDK (from JDK 1.7 update 40) and it works great.

In my case, the issue was the usage of wrong JDK version. My App was running on jdk1.7.0_80, VisualVm running with jdk1.8.0_162. Replacing the APP JDK version from 1.7.0_79 to 1.7.0_80 fixes the problem.
