External - Server-Monitoring

What is External Server Monitoring?

External server monitoring refers to the monitoring of servers, websites, and online services by an independent system outside of your own IT infrastructure.

This involves regularly checking whether a service is accessible from the internet and functioning correctly – as real users would experience it.

External monitoring detects outages even when your own systems are no longer accessible.

What is monitored during external monitoring?

Typical checks include:

• Uptime: Is the server or website online?

• Response Time: How quickly does the service respond?

• Services & Ports: Are web servers, mail servers, or APIs functioning correctly?

• Content Check: Is the expected page or response being delivered?

• Regional Availability: Is the service accessible from different locations?

Why is External Server Monitoring Important?

Internal monitoring reaches its limits when:

• the server fails completely
• network or routing problems occur
• DNS stops working
• your own monitoring instance is affected

External monitoring offers:

• independent failure detection
• early warnings, often before customers are affected
• objective availability data
• support for SLA compliance
• transparency regarding the duration and frequency of outages
