AlwaysUp is designed to run your application as a Windows Service and automatically restart it when it crashes or stops for any reason. Even though this frees you from having to take any action on a failure (eliminating those unwelcome “server-not-working” calls at 3 AM), you may still want to:
Find out how often your application is failing
Know the time when your program stops working (for diagnostic purposes)
See how your application is using CPU and memory over the course of the day
Find out whenever your server has been rebooted
Automatic email from AlwaysUp will tell you all that, and more!
Specifying Who to Email & When to Send a Message
To setup email in AlwaysUp, edit your application and switch to the Email tab:
Enter the following:
The email address to notify. To send to multiple addresses, just separate each one with a comma (,).
When AlwaysUp should send you an email — either in response to an important event, or at a regular time. The daily and weekly summary emails are a good way to monitor your application’s activities without having to receive multiple emails throughout the day.
A line of text to be included in the email. This value is optional, but you can use it to explicitly label a server & application when you have many installed with the same name (for example, when you are running the same application on many different workstations).
Server/SMTP Settings
AlwaysUp doesn’t require that you have Outlook or any other email software installed. Instead, it deals directly with your SMTP server – the machine actually responsible for routing your email over the Internet and delivering it to your recipients. Every major provider (such as Gmail, Yahoo and Office 365) supports SMTP mail and it is simply a matter of providing those settings to AlwaysUp so that it can send messages on your behalf.
Click the Configure… button to reveal the details:
The Configure Email Settings window that comes up requests quite a bit of information, but don’t be scared! Your systems administrator will be able to fill this in while balancing a bowl of water on his head and dancing the Macarena, but in case you are entering these values yourself here is what each field means:
Address: The email address that will be displayed in the “From” field of the email messages sent by AlwaysUp.
Name: The name that will be displayed in the “From” field of the email messages sent. This value is optional.
Name/IP: The name (or IP address) of your mail server.
Port: The numeric port on which the mail server is available. Note that the default is 25 for regular SMTP servers and 465 for servers using SSL – please specify one if these if in doubt.
This server requires encryption: Check and make the appropriate selection if the mail server uses TLS, SSL or STARTTLS.
This server requires authentication: Check if the server requires authentication, and select the authentication method. The choices are CRAM-MD5, AUTH-LOGIN, AUTH-PLAIN, and AUTH-NTLM. A login and a password will be required for all but AUTH-NTLM.
Login: The user name/login for the mail server. Usually your full email address.
Password: The password for your email account.
How to use your Gmail Account
To send email with your Gmail account, please specify the following settings:
Address:
Your full gmail address (your-user-name@gmail.com)
Name:
Your name
SMTP Server Name/IP:
smtp.gmail.com
Port:
465
Encryption:
SSL/TLS
Authentication:
AUTH-LOGIN
Login:
Your full gmail address (your-user-name@gmail.com)
Password
Your gmail password
So for someone named Mike Jones, whose Gmail address is jones1985@gmail.com, the Configure Email window should look something like this:
This short, step-by-step video highlights the settings to enter for Gmail:
If not, you may get an error like this when you try to send a test email from AlwaysUp:
How to use your Microsoft Office 365 Account
If you have an Office 365 mail account, please specify the settings described here:
Address:
Your full Office 365 email address
Name:
Your name
SMTP Server Name/IP:
smtp.office365.com
Port:
587
Encryption:
STARTTLS
Authentication:
AUTH-LOGIN
Login:
Your full Office 365 email address
Password
Your Office 365 password
So for Mike Jones, whose Office 365 email address is mike.jones@somecompany.com, the Configure Email window should look something like this:
Note: Because of changes to Office 365 authentication methods, attempts to send email with Office 365 may fail with this message: “Authentication unsuccessful, basic authentication is disabled”.
To overcome that problem, we recommend creating an app password for sending email using office365.com.
Create a Free Account with SMTP2GO
If you don’t want to (or can’t) use an existing email address, we recommend creating a free account at SMTP2GO. Their free plan will allow AlwaysUp to send you up to 1,000 emails per month.
Address:
Your SMTP2GO email address
Name:
Your name
SMTP Server Name/IP:
mail.smtp2go.com
Port:
2525 (or 465, 80, 25, 8025 or 587 if that doesn’t work)

Crashes and memory leaks are particularly offensive when the occur in windows services – applications designed to run unattended, 24/7 in the background to perform important tasks. Our AlwaysUp and Service Protector utilities go a long way to diminishing the effect of these insidious failures, but using them is no substitute for finding and fixing a problem at its root.
Developers looking to diagnose failures in their windows services should consider using Microsoft’s Debug Diagnostic Tool. This free desktop application, nicknamed DebugDiag, will monitor your windows service process and create a “dump” describing the state of the application when it crashed (or started using too much memory). You can use this information to narrow down the problem in your own code, or pass it on to the folks who developed the failing service for their expert analysis.
Using the Debug Diagnostic Tool on your Windows Service
Download the Debug Diagnostic Tool from microsoft.com.
Install it. Setup should be quite straightforward, with the usual prompts for a folder, etc.
From Windows Explorer, navigate to the folder where DebugDiag was installed (C:\Program Files\DebugDiag by default). Start DebugDiag.Collection.exe – the application that monitors and collects information from a running process or service.
The Debug Diagnostic Tool window should come up and you will be launched immediately into setting up a new “rule” describing what to watch for. From here, you can specify to monitor for crashes, leaks, and even performance-related issues. We’ll select Crash for this tutorial and click Next to move on.
Next, select the A Specific NT service option:
Select the service you wish to debug from the list. We chose “AA MyService”, a windows service we developed to test our Service Protector application. Click Next.
Almost there! Leave the Advanced Configuration settings at their default values and click Next to continue:
You don’t have to make any changes on the Select Dump Location screen either – just make a note of where the dump file will be saved.
And finally, let’s activate the rule now and click Finish:
After a few seconds, the tool will be monitoring your windows service for crashes:
Analyzing a Windows Service Crash
When the service crashes, DebugDiag will record a dump file and increment the Userdump count column. Here we can see that 1 crash has occurred and been captured (with the full path to the dump file noted on the right):
To dig into the dump file:
Start DebugDiag.Analysis.exe from Windows Explorer:
The DebugDiag Analysis window will open momentarily:
To configure analysis:
Check the CrashHangAnalysis box near to the top.
Click the Add Data Files button, navigate to the location of the dump file (it is mentioned in the Diagnostic tool we set up previously) and select it. A new entry should show up in the lower pane.
And click the Start Analysis button to get going! After a period of “thinking”, the application will open its report in your browser:
Scan the report for any smoking guns. Thread call stacks may be particularly useful. For example, this stack trace tells us that our service crashed while handling a button press. (This is not surprising though – that is what we did to force the crash in our testing!)
Hopefully you will find a telltale sign to help you identify and fix your problem.
Also Find Memory Leaks in your Windows Service
If your windows service is consuming too much memory instead of crashing, configure the collector to watch for memory leaks:
The final report will detail all outstanding memory allocations.
Better support for Dropbox, Google Drive and other Applications
Programs that allow you to run only a single copy at a time would occasionally prevent AlwaysUp from starting its own copy in the background. For example, if someone started a copy of Dropbox on their desktop, trying to launch a second copy under AlwaysUp would lead to Dropbox exiting quickly and the service failing to start.
Checking the new Stop all copies of the application running on this computer setting on the Startup will resolve the issue. Instead of simply trying to launch a second copy of your program, AlwaysUp will first stop any existing instances, ensuring that its own copy will start smoothly.
We recommend using this setting with the following applications:
… and any others that should only run a single instance.
Additional Power Management Options
To prevent your computer from automatically going to sleep while your important program is being run by AlwaysUp, check the corresponding box on the Extras tab:
Reduced Event Logging
As it runs your application as a Windows Service, AlwaysUp writes information, warnings and errors to the Windows Event Log. Usually this is a good thing, keeping you up-to-date on your application’s comings and goings, but it becomes rather “noisy” for applications designed to start and stop frequently. For example, if you have a batch file configured to run every ten minutes, more than 20 events will be generated per hour!
Check the new Minimize event logging as the application stops & restarts box on the Restart tab to improve the situation. Afterwards, you should only see a message when the application starts or terminates unexpectedly. Normal/expected stops and restarts will not be recorded.
Be sure to check out the AlwaysUp Version History for the full list of features, fixes and improvements included in this release.

If you find that your application is starting and then quickly stopping when you run it with AlwaysUp, your application may be trying to report an error message that you simply cannot see. In this situation, we recommend starting your application from a command prompt running as a service, to find out if something useful is being written to the console.
How to start CMD.EXE as a service on your desktop
Highlight your troublesome application in AlwaysUp and select Add Copy… from the Application menu.
(In this guide, our “StartServer” batch file is failing for some unknown reason so we’ll work with that entry…)
In the Add Application window that comes up:
In the Application field, enter the full path to the windows command prompt. This is:
C:\Windows\System32\cmd.exe
If there is anything in the Arguments field brought over from the application you copied, please remove it.
Change the Name field to something meaningful. We have entered “CMD Testing” in this guide.
Set the Start the application field to Manually, from AlwaysUp. We don’t want this command prompt service to start automatically at boot.
If you have specified a user on the Logon tab, switch over there and re-enter the password (a security measure).
Those are all the changes we need to make so click the Save >> button to record your new service. It will show up on the AlwaysUp console soon.
Next, start the new CMD service on your desktop by selecting Application > Start “CMD Testing” in this session:
In a few seconds, the familiar black box will pop up on your desktop:
And finally, in the command box, type in the full command line you gave to AlwaysUp — application & arguments. Be sure to specify the exact values that you had supplied to your AlwaysUp service! Please cut & paste to ensure accuracy.
Hit Enter to run your application and pay special attention to what is written to the command prompt.
Hopefully at this point your application will tell us what is wrong! In our case (pictured below), the batch file can’t find the JAR file it is expecting…
Once you’ve fixed the problem and verified that your application can start normally with AlwaysUp, please feel free to remove the CMD service by highlighting the entry in AlwaysUp and selecting Application > Remove.
The next version of Windows, dubbed Windows 10 is expected to be released in the second half of 2015. On October 1, Microsoft provided software makers with an early look at the new OS, so that we can test and certify our applications in advance of the launch. And like a kid in a candy store, we downloaded and eagerly installed the Windows 10 Technical Preview on a VirtualBox VM. The most noticeable change? The return of the Start menu! Finally, Microsoft has come to its senses.
Next, it was on to testing our software. Service Protector, which monitors and automatically restarts failing windows services, passed with flying colors. There with no issues whatsoever. Here it is happily monitoring the Print Spooler service:
However, things did not go as smoothly for AlwaysUp, our popular utility that runs any application as a windows service. We set up Notepad.exe as a service but quickly ran into trouble starting it:
After a couple of hours of debugging the code, it turns out that the problem is related to to the little-used user reboot notification feature recently introduced in Windows 8 & Server 2012. To avoid getting too technical, let’s just say that the new capability is simply not accepted by Windows 10. Using it causes AlwaysUp to fail to transition the service into the running state and remain in the starting state. And since no controls are accepted in the starting state, all the action buttons are grayed out and the service will remain stuck starting forever! The only way to stop the service is to disable all recovery actions for the service and forcibly terminate AlwaysUpService.exe from the Task Manager. A real mess!
We have reported the problem to Microsoft and hopefully they will resolve it before the official release of Windows 10 next year. If not, a change to our code to eliminate the user reboot notification feature will also fix the problem, so not to worry. We’ll stay on top of it 🙂
