App::SuperviseMe - very simple command superviser
my $superviser = App::SuperviseMe->new( cmds => [ 'plackup -p 3010 ./sites/x/app.psgi', 'plackup -p 3011 ./sites/y/app.psgi', ['bash', '-c', '... bash script ...'], ], ); $superviser->run;
This module implements a multi-process supervisor.
It takes a list of commands to execute and starts each one, and then monitors their execution. If one of the program dies, the supervisor will restart it after a small 1 second pause.
You can send SIGTERM to the supervisor process to kill all childs and exit.
You can also send SIGINT (Ctrl-C on your terminal) to restart the processes. If a second SIGINT is received and no child process is currently running, the supervisor will exit. This allows you to tap Ctrl- C twice in quick succession in a terminal window to terminate the supervisor and all child processes
my $supervisor = App::SuperviseMe->new( cmds => [...], [debug => ...]);
Creates a supervisor instance with a list of commands to monitor.
It accepts a hash with the following options:
A list reference with the commands to execute and monitor. Each command can be a scalar, or a list reference.
Print progress information if true. Disabled by default.
Print debug information if true. ENV SUPERVISE_ME_DEBUG overrides this setting. Disabled by default.
my $supervisor = App::SuperviseMe->new_from_options;
Reads the list of commands to start and monitor from
STDIN. It strips white-space from the beggining and end of the line, and skips lines that start with a
Returns the superviser object.
Starts the supervisor, start all the child processes and monitors each one.
This method returns when the supervisor is stopped with either a SIGINT or a SIGTERM.
