Paessler PRTG SMS & voice calls notifications.

24/7 monitoring you can rely on.

Combine the powerful PRTG Network Monitor system with the reliability of the SMSEagle hardware gateway.
Make sure you are the first to know about critical failures – even if your network goes completely down.

Benefits

Internet-independent alerting

PRTG detects infrastructure anomalies, but delivering those alerts usually depends on your internet connection, mail server, or a cloud SMS provider. If any of these fails, the notification never reaches you. SMSEagle sends alerts directly over the mobile network, so they get through even when your internet link is down.

Dedicated, standalone
hardware

Software-based alerting often runs on the same virtualized infrastructure (e.g. Proxmox or VMware) it is meant to protect. If that platform fails, your alerting can fail with it. SMSEagle is dedicated hardware with its own cellular connection, so your alerting gateway doesn’t share fate with the servers
around it.

No cloud, full data control

SMSEagle runs on-premises, so alerts aren’t routed through third-party cloud SMS providers. Messages are sent directly from on-prem device over the cellular network to mobile carrier, keeping alert data off external SaaS platforms.

How it works?

1 Event Trigger

PRTG detects an issue in the infrastructure (e.g., a server failure or excessive temperature in the server room).

2 Communication

PRTG immediately sends information to the SMSEagle device via the local network — using HTTP API.

3 Alert

SMSEagle sends an SMS notification or initiates a voice call to a predefined group of recipients.

Integrate in 10 minutes

Don’t waste time on complicated configuration. Thanks to HTTP API support in SMSEagle and notification templates in PRTG, you can get everything up and running in the time of a coffee break. Configure SMSEagle, paste the URL into PRTG settings — and you’re done. Alerts will start working immediately.

Monitoring is just the beginning.
Take full control of alerts and automation.

SMS and voice alerts

A text alert can be missed, especially at night or on a noisy site floor. SMSEagle delivers PRTG alarms as SMS and as voice calls. A ringing phone with a text-to-speech message is much harder to sleep through than a silent notification. With the Voice-Call add-on, every critical PRTG event can trigger an actual phone call, so the right person is reached even when a text wouldn’t be.

Recipient and escalation groups

Not every alert should go to everyone, and a missed alert shouldn’t go nowhere. SMSEagle lets you define recipient groups so each PRTG sensor reaches the right team. Escalation groups ensure that if the first person doesn’t acknowledge, the alert moves on to the next responder. Combined with on-call shift schedules, notifications follow your real duty roster instead of a static phone number.

Monitor PRTG itself

Who watches the watcher? If your PRTG server goes down, it can no longer send a single alert, and you may not find out until it’s too late. With SMSEagle’s built-in Network Monitoring, the gateway independently checks your PRTG server and sends an SMS or voice call the moment it stops responding. Your monitoring platform finally gets a monitor of its own.

Create Notification Templates in PRTG

You can now create Notification Templates in Setup > Account Settings > Notification Templates to automatically trigger the sending of SMS text with alerts from PRTG. In the notification template, choose Send SMS/Pager Message and select a user or user group with a defined SMS contact or provide an individual phone number.

That’s it! SMS alerts are ready!

PRTG Wake-up Calls Setup (optional)

SMSEagle device allows you to setup wake-up (ring only) calls as a notification. This is an efficient way to draw someone’s attention, for example in the middle of the night. Here is how to set up wake-up calls on PRTG.

Notice: Voice functions are only available to users who have purchased the VOICE add-on for their SMSEagle device.

In the PRTG web interface open Setup > Account Settings > Notification Templates

Add new Notification Template

enter Template Name (for example: SMSEagle Wake-up Call)
choose Notification Summarization Method: Always notify immediately, never summarize (or other according to your preference)
enable Execute HTTP Action
- set HTTP Method to GET
- set URL to: https://URL-OF-SMSEAGLE/http_api/ring_call?access_token=YOUR-API-TOKEN&to=PHONE-NUM&duration=30
- In the string above replace:
  - use http or https (depending how you access your SMSEagle device)
  - URL-OF-SMSEAGLE with IP Address of your SMSEagle device
  - YOUR-API-TOKEN with API acccess token you created in Step: SMSEagle Setup.
  - PHONE-NUM with destination phone number

Save notification.

Click on the Send Test notification (bell icon) to test.

How to monitor your PRTG server? (optional)

PRTG is a perfect monitoring tool, but what if its server hardware fails? Even the best hardware can experience failures. That’s where SMSEagle steps in with its feature called Network Monitoring. SMSEagle can monitor IP addresses or TCP ports and instantly send an SMS or make a call when a failure is detected. This ensures you can always keep an eye on your monitoring server.
