Process Restarter

[Phill64]

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)

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);
			}
			
			
			
		}
