Why SIGNL4
PRTG Network Monitor is an agentless network monitoring software from Paessler AG. It can monitor and classify system conditions like bandwidth usage or uptime and collect statistics from miscellaneous hosts as switches, routers, servers and other devices and applications. A major issue about the mobile app is you cannot see who is on call or members from your team. If an alert comes in and you need to collaborate with a team member, there is no way of knowing who is currently on call. SIGNL4 displays active team members directly on the app so you know who to contact if a critical alert comes in and you are not the subject matter expert.
How it Works
SIGNL4 establishes connection with PRTG Network Monitor via webhook or email to enable mobile notification and alerting capabilities for operations teams.

HOW TO INTEGRATE
There are two ways for integrating SIGNL4 with PRTG. This is via HTTP request or via email.
1. HTTP Request
First you need to create a new Notification Template at Setup -> Account Settings -> Notification Templates. Here you choose Execute HTTP Action where you can specify your SIGNL4 webhook URL including the team secret, select the HTTP Method Post and enter the Payload including placeholders.
The payload might look like this: Title=Alert from PRTG&Site=%sitename&Message=%device %name %status %down (%message)
Here you can find a description about the supported placeholders: https://kb.paessler.com/en/topic/373-what-placeholders-can-i-use-with-prtg
So you have a format like this: Parameter1=Value1&Parameter2=Value2, etc.
Resolve Alerts: In order to support the resolution of alerts in SIGNL4 you can just add the following part to your SIGNL4 webhook URL:
?ExtIDParam=sensorid&ExtStatusParam=laststatus&ResolvedStatus=Up
So, the complete URL looks like this:
https://connect.signl4.com/webhook/team-secret?ExtIDParam=sensorid&ExtStatusParam=laststatus&ResolvedStatus=Up
Where “team-secret” is your SIGNL4 team secret. You then need to add the parameters “sensorid” and “laststatus” to the Payload:
Title=%device: %name&Message=%message&sensorid=%sensorid&laststatus=%laststatus
You can find more information about the resolution of alerts in SIGNL4 here: https://www.signl4.com/blog/update-july-2020-resolve-alerts/. You can easily test the SIGNL4 notification template from here.
Then, at Devices -> Notification Trigger, you can specify your notification trigger including the conditions and the SIGNL4 notification template.
2. Email
Create a user within PRTG with the name of SIGNL4 and your team email address. Assign that user to a group that is monitoring existing sensors.
Note: In the screenshot below the user name is S4, email address is your team email and the user is part of the PRTG Users Group.
At this point the next time something triggers an alarm, your S4 team will be notified via the mobile app.
See left how an alert looks in S4.
ALERT OPTIMIZATION
SIGNL4 can further increase the visibility of alerts through its Signals and Services section. Augmenting the color and icon of alerts will provide more relevant information at a glance without having to open the alert.
