Process Restarter

A common quick/temporary fix for server administrators is to check if software has crashed and restart it.

So Here's a simple console application that will do that for you. It accepts 2-3 paramaters

Usage:
ProcessRestarter <processName> <restartcommand/exe location> [interval-ms]

Example:
ProcessRestarter failware C:\servers\failware.exe 30000

The above example will check if the process 'failware' is running every 30 seconds, and if not, will start a new process at 'C:\servers\failware.exe' (so now. no need for human intervention to restart the failware app if it crashes, just check the restarters console window to see if a crash has occured)

the interval is optional and will default to 60,000ms (60 seconds)

Code:

---

using System;
using System.Diagnostics;

namespace ProcessRestarter
       
{
        class Program
        {
                public static void Main(string[] args)
                {
                        Console.WriteLine("Process Restarter is booting...");
                        string processName = "";
                        string restartCommand = "";
                        int interval = 60000;
                       
                        if(args.Length >= 2) {
                                processName = args[0];
                                restartCommand = args[1];
                                if(args.Length >= 3) int.TryParse(args[2],out interval);
                                Console.WriteLine("Scanning for Process name: " + processName);
                                Console.WriteLine("If not found, will send system command: " + restartCommand);
                                Console.WriteLine("Scan will occur every " + interval.ToString() + "ms");
                                while(true) {
                                        if(Process.GetProcessesByName(processName).Length == 0) {
                                                Console.WriteLine("[" + DateTime.Now.ToString("dd/MM/yyyy") + " " + DateTime.Now.ToShortTimeString() + "] Process not found, sending restart command");
                                                Process.Start(restartCommand);
                                                System.Threading.Thread.Sleep(2000);
                                        }
                                               
                                        System.Threading.Thread.Sleep(interval);
                                }
                        } else {
                                Console.WriteLine("Not enough parameters specified.\nUsage .exe <processname> <restartcommand/exe location> [interval-ms]\nscan interval is optional and defaults to 60000 ms");
                                Console.Write("Press any key to continue . . . ");
                                Console.ReadKey(true);
                        }
                       
                       
                       
                }
        }
}
