What is a Monitoring service and how does it work?

Monitoring service – What is it?

Monitoring service helps with identifying issues regarding your services such as web, DNS, email, and so on. Therefore, it is an essential thing you should implement if you want to provide not only reliable service but also a great user experience. This service supplies information about the condition of your servers in a pretty detailed way. Additionally, thanks to it, you can notice and fix many issues in a short amount of time by checking your servers in real-time. So, if a particular element of your network is very sluggish or it fails, you can detect it and act fast.

With the Monitoring service, you can also set automatic notifications, and if there is a problem, you are going to get an email or a text.

How does it work?

In order to understand the condition of your services, the Monitoring service provides different types of checks. They notice if one service is UP or DOWN. Then, if a check fails, you are notified. The most common types of checks are the following:

Website HTTP(s) – It sends HTTP(S) requests to a precise IP address or a web. If the HTTP response code is 200, the system marks it as UP. You can change several parameters – path, port, and hostname.

Transmission Control Protocol (TCP)TCP monitoring makes a connection to the assigned IP (IPv4 or IPv6) address on the selected port number. If it fails, it marks it as DOWN.

User Datagram Protocol (UDP) – It makes a UDP connection to the precise IP (IPv4 or IPv6) address and port number. If it fails, it marks it as DOWN.

Domain Name System (DNS) – It makes a DNS query for the chosen hostname. You are able to change the query type on the given IP address. 

Ping (ICMP) – It sends ICMP ping requests to a precise IP address and informs about the network activity for a certain domain or IP address. When a specific percentage of the packets fail, the system marks the check as DOWN.

Why use a Monitoring service?

There are several really important reasons why you should implement a Monitoring service.

You can avoid unwanted outages.

Prevention is key, and a Monitoring service could help you detect and avoid different issues causing downtime and DNS outage. It is a really simple and easy approach. Information in real-time gives you the opportunity to act really fast.

You have better visibility of your network.

The Monitoring service improves visibility by indicating network performance information in real-time, sending notifications via email, text and presenting it in a simple to understand way. 

It takes your security to the next level. 

Time is crucial for online businesses, especially in down events. The Monitoring service is going to help you to get to the bottom of any issue. That is very beneficial for improving the security and detecting cyber threats, such as DDoS (Distributed Denial of Service) attacks and DoS (Denial of Service) attacks. The usual goal for such attacks is to overwhelm the target with malicious traffic and keep it down for a long time.
