Firemon - Monitoring program for processes started in a Firejail
sandbox.
firemon [OPTIONS] [PID]
Firemon monitors programs started in a Firejail sandbox. Without
a PID specified, all processes started by Firejail are monitored.
Descendants of these processes are also being monitored. On
Grsecurity systems only root user can run this program.
--apparmor
Print AppArmor confinement status for each sandbox.
--arp Print ARP table for each sandbox.
--caps Print capabilities configuration for each sandbox.
--cpu Print CPU affinity for each sandbox.
--debug
Print debug messages
-?, --help
Print options end exit.
--list List all sandboxes.
--name=name
Print information only about named sandbox.
--netstats
Monitor network statistics for sandboxes creating a new
network namespace.
--route
Print route table for each sandbox.
--seccomp
Print seccomp configuration for each sandbox.
--top Monitor the most CPU-intensive sandboxes. This command is
similar to the regular UNIX top command, however it applies
only to sandboxes.
--tree Print a tree of all sandboxed processes.
--version
Print program version and exit.
--wrap Enable line wrapping in terminals. By default the lines are
trimmed.
--x11 Print X11 display number.
The format for each listed sandbox entry is as follows:
PID:USER:Sandbox Name:Command
Listed below are the available fields (columns) in various firemon
commands in alphabetical order:
Command

CPU% CPU usage, the sandbox share of the elapsed CPU time since
the last screen update
PID Unique process ID for the task controlling the sandbox.
Prcs Number of processes running in sandbox, including the

RES Resident Memory Size (KiB), sandbox non-swapped physical
memory. It is a sum of the RES values for all processes
running in the sandbox.
Sandbox Name
The name of the sandbox, if any.
SHR Shared Memory Size (KiB), it reflects memory shared with
other processes. It is a sum of the SHR values for all
processes running in the sandbox, including the controlling
process.
Uptime Sandbox running time in hours:minutes:seconds format.
USER The owner of the sandbox.
