Batch Processing

With the help of Batch Processing, you can run multiple commands in batch and get the final result at the end.


Step 1: Create the script

Create a script suffixed with as. Here as is suggested for the suffix of the filename, but in fact any suffix is acceptable.

➜  arthas git:(develop) cat /var/tmp/
dashboard -n 1
sc -d org.apache.commons.lang.StringUtils


  • Each command takes one line.

  • Batch mode execution times (via -n) must be explicitly specified for dashboard, otherwise batch script cannot terminate.

  • Commands such as watch/tt/trace/monitor/stack should include -n option to ensure the script can be able to quit.

  • Also consider to use async (for example: watch c.t.X test returnObj > &) to put commands run at background and get the output from the log file, see more from asynchronous job

Step 2: Run the script

Use -f to specify the script file. By default the result will be output to the standard output, but you can redirect the output to the file like this:

./ -f /var/tmp/ 56328 > test.out

Use -c also can specify the commands, like this:

./ -c 'sysprop; thread' 56328 > test.out

Step 3: Check the output

cat test.out
