How to stop running service

Dani_S 3,786

Hi,

I have worker service that run quartz sceduler.

The question regard to service.

When quartz sceduler is running and for example there is no space in disk i want to stop the service.

Is it possible if yes please give sample code ?

Thanks,

Hi @דני שטרית ,Welcome to Microsoft Q&A,

I don't know the quartz scheduler you are talking about, but if you want to shut down the service when there is no memory, there is indeed relevant sample code.

To monitor disk space and stop the service if it falls below a certain threshold. You can achieve this by periodically checking the available disk space using the DriveInfo class in C#. Here's a basic example of how you can implement this logic in your worker service:

using System;

using System.IO;

using System.ServiceProcess;

using System.Timers;

namespace DiskSpaceMonitorService

{

    public class DiskSpaceMonitorService : ServiceBase

    {

        private Timer timer;

        private string driveLetter = "C"; // Change this to the drive letter you want to monitor

        private double thresholdInBytes = 1e9; // Change this to the threshold in bytes (e.g., 1 GB)

        public DiskSpaceMonitorService()

        {

            this.ServiceName = "DiskSpaceMonitorService";

        }

        protected override void OnStart(string[] args)

        {

            // Set up timer to check disk space every 5 minutes

            timer = new Timer();

            timer.Interval = 5 * 60 * 1000; // 5 minutes

            timer.Elapsed += TimerElapsed;

            timer.Start();

        }

        protected override void OnStop()

        {

            timer.Stop();

        }

        private void TimerElapsed(object sender, ElapsedEventArgs e)

        {

            CheckDiskSpace();

        }

        private void CheckDiskSpace()

        {

            DriveInfo drive = new DriveInfo(driveLetter);

            if (drive.AvailableFreeSpace < thresholdInBytes)

            {

                // If available free space is below the threshold, stop the service

                this.Stop();

            }

        }

        public static void Main(string[] args)

        {

            ServiceBase.Run(new DiskSpaceMonitorService());

        }

    }

}

In this example, the CheckDiskSpace method is called periodically by a timer. It checks the available free space on the specified drive (driveLetter) and compares it with the threshold (thresholdInBytes). If the available free space is below the threshold, the service is stopped.

Additionally, this code assumes you're creating a Windows service.

public static void StopService(string servicName) { try { ServiceController service = new ServiceController(servicName); service.Stop(); service.WaitForStatus(ServiceControllerStatus.Stopped); } catch (Exception ex) { _logger.Error("StopService", ex); } }

Hi @דני שטרית , Welcome to Microsoft Q&A,

There are a few points to consider and potential improvements:

Error Handling: This method is good for catching exceptions and logging them. Depending on your requirements, you may want to handle specific types of exceptions differently or provide more detailed error messages.

Timeout: The WaitForStatus method waits indefinitely by default. You may want to consider adding a timeout mechanism to prevent the application from hanging indefinitely if the service is not stopped within a reasonable time frame.

Logging: Make sure "_logger" is configured correctly and that you handle logging correctly in your application.

Permissions: The application running this code may require appropriate permissions to interact with SCM and stop the service, please ensure that the application has the necessary permissions, especially in a production environment.

Test: Test the method thoroughly to make sure it works as expected under various circumstances, such as when the service is stopped or there are communication issues with the SCM.

I ran this function within the service iteself.

can you please supply code for timeout mechanism ?
