Tomcat available memory
In Tomcat's JVM settings following parameters are configured :
-verbose:gc -XX:+PrintGCDateStamps -XX:+PrintGC -Xloggc:logs/gc.log
which prints log in file like below:
2015-12-11T15:42:06.779+0530: 5.662: [GC [PSYoungGen:
115711K->26741K(218624K)] 159969K->71550K(283136K), 0.0305672 secs] [Times:
user=0.02 sys=0.02, real=0.03 secs]
I want to print like below in log file:
Free memory: 244.47 MB Total memory: 512.00 MB Max memory: 910.50 MB
What parameters need to set in JVM option of Tomcat to achieve this?

Verbose GC isn't going to show you that, you'll have to take other steps.
You can get the information you are looking for via JMX any time you'd
like, though:

You need to look at the options for the JVM that you are using.
That is not within the scope of Tomcat.
It is not Tomcat writing this, it is the JVM. And it is not "Tomcat's JVM", it is the "JVM
vendor's JVM" (Oracle, IBM or whatever).
