Is there a way to list process arguments as well using monit

Question

I setup monit on Ubuntu 16.04.

sudo monit --version
This is Monit version 5.16
Built with ssl, with pam and with large files

For a given process, it currently lists below:

  status                            Running
  monitoring status                 Monitored
  pid                               8724
  parent pid                        8691
  uid                               0
  effective uid                     0
  gid                               0
  uptime                            6d 23h 36m 
  threads                           7
  children                          0
  memory                            190.6 MB
  memory total                      190.6 MB
  memory percent                    19.2%
  memory percent total              19.2%
  cpu percent                       6.8%

My question is that is there a way I can also list process arguments in this list? Basically, I would like to monitor not only matrices like uptime, load etc. but also what arguments the process is called and running with? Are there any other alternatives to monit that could provide a similar json based response?

Thanks.

There is a way to do what you want. On any Linux based system, you can use:

xargs -0 < /proc/<pid>/cmdline

Make sure you replace <pid> with your processes pid. That command will show the command that started the pid you inserted into that path, with args and all. You can even make a shell script to run monit and parse the pid section from the output and use that for xargs.
