Pman

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.

Usage

Configuration file

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

Start server

$ pman
# specific conf file path
$ pman -c ./pman.conf

Run client

$ 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 conf

You can use "all" to operate all registered programs.

$ pman stop all
[sample] STOPPING
[sample2] STOPPING
[sample3] STOPPING

$ pman start 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: 00:00:02

gRPC

Pman server adopts gRPC as a protocol for IPC.
You can call pman's API from client program written in programming language supporting gRPC.
Please check pman.proto file.
