How to use the Service Manager feature in WHM

Introduction

Managing your services and selecting the most important ones you want to monitor is a great option to have. The “Service Manager” feature in the WHM control panel will allow you to enable or disable certain services and turn on or off their monitoring. Your system's services are typically all started automatically when a server boots up. In addition, WHM has a monitoring system that will automatically restart a service if it crashes. You will rarely need to restart the services manually, but WHM does provide you with the functionality to do so. In this tutorial, we are going to talk about the way you can see what services are enabled and monitored by WHM and how you can change that or add new ones. Let’s get started.

 

Accessing the Service Manager feature in WHM

First, you need to log into the WHM service for your VPS or Dedicated Server. If you are not sure how to do that, please check our How to access the WHM service tutorial. After you have logged in, please use the search bar on the left side of the page and type “Service Manager”.

When the functionality shows up below the search bar, please click on it so you can be sent to the “Service Manager” page.

 

Changing the services you want to monitor

When you land on the page, you will notice two table sections. The first one enables or disables the various drivers of the “tailwatchd” daemon. In short, what this daemon does is monitors certain log files, and based on the output from them, it takes action. An example of that would be if it detects your IMAP service as not responding, it will attempt to restart it and get it back running to ensure that you do not miss any important emails.

 

Tailwatchd table overview

 

Let’s go over all these drivers and explain what they do.

  • APNSPush - This driver is responsible for notifying iOS-based devices when a new mail is received. 
  • ChkServd - This driver looks after the various running services (exim, httpd, crond) and will restart them if they go down.
  • Eximstats - This driver will maintain email bandwidth logs, limit email usage and populate data for the Mail Delivery Report system.
  • MailHealth - This driver will be on the lookout for problems concerning the mail services on your server.
  • ModSecLog - This will look over the ModSecurity audit log and will store events in the ModSec database so you may analyze it later if needed.
  • RecentAuthedMailIpTracker - Keeps track of the IP addresses that recently authenticated using IMAP or POP3. This would allow users to bypass delays and greylist checks.
  • cPBandwd - When enabled, this will be generating bandwidth logs for the IMAP and POP3 services.


All of these will be enabled by default when the server is set up and we highly recommend keeping them all as such. However, if you would like to disable any of them, please click on the checkbox located on the first column of the table section and make sure it corresponds to the row where the service is.

 

Disabling tailwatchd drivers

 

When you scroll down, the second section you will see is the service daemon table section. Through it, you can enable certain services and add them for monitoring and vice versa. In order to enable or disable a service, please select or respectfully deselect the checkbox which is located in the first “Enabled” column, and make sure it corresponds to the row of the service you want to alter. 

 

Disabling and Enabling services

 

If you want to enable a certain service for monitoring, use the checkbox under the second column called “Monitoring”  that corresponds to the row the service is in.

When you have made the desired changes on this page, in order to apply them, please click on the “Save” button, located on the bottom of the page.

 

Saving the changes

 

There you have it! The “Service Manager” feature in the WHM control panel explained in its entirety. We hope that we were able to give you insight into how it works and how you can alter the services that are available on your server. If you have any questions regarding this functionality, please, do not hesitate to contact our Technical Team from your Client Area by submitting a ticket.
