I see the RAM memory is lesser than Heap Memory when ran the script in a docker container. Is RAM memory is calculated by excluding heap? .Because heap memory should be a part of RAM right ?

Wrong repository or published wihout being teste ?

Hi! First of all, thanks for this tool, it's really helpful!
This issue happens all the time, after running it for a while:

cut: /proc/36627/statm: No such file or directory
./jpsstat.sh: line 93: / 1024 : syntax error: operand expected (error token is "/ 1024 ")

Redhat RHEL 7.

hello, when I log into a log file I have a problem with special char at the begining.

How to remove them ?

Hi,
great script. But if I execute the script I get this error:
./jpsstat.sh: line 89: printf: 234.637: invalid number ./jpsstat.sh: line 89: printf: 234.637: invalid number ./jpsstat.sh: line 89: printf: 1.1: invalid number
I found the issue in the printf command where %f has issues to work with decimal numbers. Therefore I modified a few lines:

   MEMORY_T=$(jstat -gc $pid | tail -n 1 | awk '{split($0,a," "); sum=a[3]+a[4]+a[6]+a[8]; mb=sum/1024; print mb}')
        MEMORY=${MEMORY_T%.*}

and
printf "%-6s %-44s %8.2f %8.2f %5.1s\n" $pid ${curr_pid_name["$pid"]} $MEMORY ${curr_pid_max["$pid"]} $cpuuse | sort

It's just a workaround. Hope that helps.

We need to document all the supported options in README.md

The readme doc is outdated. In recent development, we have got few more options. All the available options can be seen by running ./jpsstat.sh -h.

New available options are -1 | --once and -H | --no-headers and -l

../../jpsstat.sh: line 98: jps: command not found

Running inside a docker container.
Current working directory is jdk/bin, and jps is present.

sh-4.4# ls | grep jps
jps
