Pman is a process management tool for starting/stopping, automatic restart, and status monitoring.
Pman intends to run on a UNIX-based OS, and currently it has been tested on Mac OSX and Ubuntu.
Pman is inspired by Supervisor in several ways.
Pman reads the configuration file (default: /etc/pman.conf) at startup.
The configuration file has 2 sections; a section that describes the settings of the daemon and a section that describes the setting of the program to be executed.
Pman has echo command that shows default configurations.
$ sudo sh -c './bin/pman echo > /etc/pman.conf'
$ cat /etc/pman.conf
[pman]
pidfile=/tmp/pman.pid ; pman daemon's pidfile
logfile=/tmp/pman.log ; pman daemon's logfile
port=127.0.0.1:50010 ; gRPC server port
directory=/tmp ; default is current dir
[program:sample]
command=/bin/ls ; program command
stdout=/tmp/sample_stdout.log ; program stdout logfile (default: /tmp/${program name}_stdout.log)
stderr=/tmp/sample_stderr.log ; program stderr logfile (default: /tmp/${program name}_stderr.log)
autorestart=true ; automatically restart if exited unexpectedly
autostart=true ; start program on daemon's startup$ pman
# specific conf file path
$ pman -c ./pman.conf$ pman <command>
command:
status <program> show status
start <program> start program
stop <program> stop program
restart <program> stop and start program
kill kill daemon process
echo echo default confYou can use "all" to operate all registered programs.
$ pman stop all

[sample] RUNNING pid: 8978 uptime: 00:00:00
[sample2] RUNNING pid: 8979 uptime: 00:00:00
[sample3] RUNNING pid: 8980 uptime: 00:00:00
$ pman status
[sample] RUNNING pid: 8978 uptime: 00:00:02
[sample2] RUNNING pid: 8979 uptime: 00:00:02
[sample3] RUNNING pid: 8980 uptime: 00:00:02Pman server adopts gRPC as a protocol for IPC.
You can call pman's API from client program written in programming language supporting gRPC.
