I'd like to add a URL to our email template that allows the on-call personnel to acknowledge alarms without having to login to the web interface. This would be primarily used on mobile devices.

This is possible as of PRTG 7.3.2

As of 7.3.2 the %sensorid placeholder is supported, so we can now edit the HTML template and insert something like:

<div class="url">
 <a href="http://192.168.1.2:8080/api/acknowledgealarm.htm?id=%sensorid&ackmsg=ok&username=admin&passhash=12345678"><h3>Acknowledge alarm</h3><a>
</div>

The top section of the HTML template would than look like:

<!-- HTML Template per Notification BEGIN -->
	<div class="head">
 		<b>%device</b>: %name %status %down (%message)
	</div>

       <div class="url">
       <a href="http://192.168.1.2:8080/api/acknowledgealarm.htm?id=%sensorid&ackmsg=ok&username=admin&passhash=12345678"><h3>Acknowledge alarm</h3><a>
        </div>
 
 	<div class="content">

You have to change the IP and portnumber to match your own PRTG installation. Also the username (admin) and passhash (12345678) are just for example purpose and have to be changed.

The user that receives the email is now presented with a link to acknowledge the alarm.

Sounds like an excellent idea though and in theory at least, not too difficult to implement - just need to ensure it's secure enough so that you don't have to log in every time but that the link alone doesn't authenticate you. Perhaps a one-time authenticated link, solely for acknowledging alerts but which doesn't fully log you in.

You guys are awesome. This addresses Adrian's concern because the API is stateless.

HTML email template part 2, hide username and passhash

Adding the

http://192.168.1.2:8080/api/acknowledgealarm.htm?id=%sensorid&ackmsg=ok&username=admin&passhash=12345678

To the email template works ok, but leaves the user with the complete visible url in his browser, including the username and passhash. To hide the username and passhash, we can make things a little bit more complicated and pass our url to the checklogin.htm page.

Our basic url, (without username and passhash) now becomes the payload for the checklogin.htm and has to be url encoded. We do however want to leave the %sensorid placeholder intact, so let's break up the basic url into 3 pieces.

Basic url

http://192.168.1.2:8080/api/acknowledgealarm.htm?id=

%sensorid

&ackmsg=ok

The first and third line now need to be url encoded:

http%3a%2f%2f192.168.1.2%3a8080%2fapi%2facknowledgealarm.htm%3fid%3d

%sensorid

%26ackmsg%3dok

Putting it back together:

http%3a%2f%2f192.168.1.2%3a8080%2fapi%2facknowledgealarm.htm%3fid%3d%sensorid%26ackmsg%3dok

We now add this to the checklogin.htm and add our username and passhash:

http://192.168.1.2:8080/public/checklogin.htm?loginurl=http%3a%2f%2f192.168.1.2%3a8080%2fapi%2facknowledgealarm.htm%3fid%3d%sensorid%26ackmsg%3dok&login=admin&passhash=12345678

Making the top section of our email template look like this:

<!-- HTML Template per Notification BEGIN -->
	<div class="head">
 		<b>%device</b>: %name %status %down (%message)
	</div>

         </div class="ull">
                <a href= "http://192.168.1.2:8080/public/checklogin.htm?loginurl=http%3a%2f%2f192.168.1.2%3a8080%2fapi%2facknowledgealarm.htm%3fid%3d%sensorid%26ackmsg%3dok&login=admin&passhash=12345678"><h3>Acknowledge alarm 2</h3><a>
         </div>

Our user is still presented with a link to acknowledge the alarm, but does not see the username and passhash in his browser anymore.

Url encoding can be done online by sites as: http://www.string-functions.com/urlencode.aspx
