PRTG is one of the most widely used monitoring tools in IT environments.

And rightly so.

Allows:

• monitor infrastructure
• supervise services
• detect drops and degradations
• generate real-time alerts

👉 is a very good basis for visibility of what is going on.

But a very common situation arises in the daily operation:

alert is generated… but no one acts in time

Especially in scenarios such as:

• after-hours shifts
• distributed teams
• multiple simultaneous alerts

That is where the problem is no longer one of monitoring.

It is reactive.

In simple

PRTG detects and alerts correctly.

But if you want to improve response times, you need to make sure of something key:

👉 that the alert arrives in a way that is impossible to ignore.

And that’s where phone calls make a difference.

Why supplement PRTG with calls?

PRTG allows you to send alerts through different channels:

• e-mail
• push notifications
• SMS (depending on configuration)

This works well in many cases.

But when the alert is critical, there is a risk:

• mail is not checked
• notification is lost
• the message is not seen in time

👉 and the incident continues to progress.

Phone calls resolve that point:

• interrupt
• generate urgency
• ensure immediate visibility

👉 do not depend on someone “checking something”.

Direct impact on operations

Adding phone calls to PRTG can generate concrete improvements:

• reduction of MTTA (recognition time)
• shorter reaction time
• less reliance on manual review
• increased SLA compliance

👉 especially in critical incidents

When does it make sense to use calls?

Not all alerts should generate a call.

In fact, this is a common mistake.

Calls work best when used in:

• critical incidents (P1 / P2)
• downtime of key services
• systems that directly impact the business
• after-hours events

👉 less volume, more impact

How call integration works

The logic is simple:

1. PRTG detects an event
2. An alert is generated
3. It is sent to a notification system
4. This system executes the phone call

During the call you can:

• reproduce a personalized message
• indicate the problem
• provide context
• allow confirmation

👉 transform an alert into immediate action

How to configure it (overview)

PRTG can be integrated with external systems by means of:

• HTTP notifications
• Webhooks
• custom scripts

The typical flow is:

1. Create a notification in PRTG
2. Configuring a webhook or HTTP call
3. Send the alert to an external platform
4. This platform executes the so-called

👉 this allows full flexibility

Example of basic configuration

Within PRTG:

• go to Notification Templates
• create a new notification
• select HTTP Action type
• set the URL of the external system

Then:

• associate that notification with critical sensors
• define activation conditions

👉 from that point on, each relevant alert can trigger a callback

Key best practices

For this to work well in operation:

• do not use calls for everything
• clearly define what is critical
• associate calls to shifts or responsible persons
• combine with automatic scaling
• include clear context in the message

👉 the call should help, not generate noise.

A simple example

No-call scenario

• PRTG detects a drop
• send mail
• nobody sees it in time

Result: delayed reaction

Scenario with calls

• PRTG detects a drop
• is executed called
• someone responds immediately

Result: fast reaction and impact control

Something important

This does not replace PRTG.

It enhances it.

PRTG remains in charge of:

• detect
• monitor
• generate alerts

The calls add up:

👉 actual responsiveness

What changes in practice

When you implement this type of integration:

• decrease reaction times
• avoid missed alerts
• improves coordination
• increases the reliability of the operation

👉 the difference is not in detecting better, but in acting better.

If you are using PRTG today and feel that alerts are not always addressed in a timely manner, probably the next step is not to change tools, but to improve how you manage those alerts.

👉 24Cevent allows integration with PRTG to transform alerts into automated phone calls, ensuring effective notification, confirmation of attention and escalation when necessary.
