What is a Monitoring service?
Monitoring service is crucial for providing a reliable service and a great user experience. In addition, it serves to identify issues regarding your services like web, DNS, email, and so on. Thanks to it, you receive detailed data about the conditions of your servers, and it helps you find and fix different problems quickly.
Additionally, you have the ability to check and notice the condition of your servers in real-time. That way, any difficulties, such as a failure of a specific component or very sluggish traffic, are easy to detect and take quick actions.
The Monitoring service also provides automatic notifications. So, if an issue appears, you are going to receive, for instance, an email, text, or in some other way.
What is the purpose of the Monitoring service?
The main goal of a Monitoring service is to notice network problems, such as:
- Server failures
- Overloaded routers
- Network connection issues
In addition, you are able to escape from unwanted outages and failures. That is crucial for online businesses which require availability and high uptime. Constant monitoring is the best way to protect the integrity of your services and networks.
You can find a lot of amazing tools out there. Yet, there is something very important that you should consider when you are choosing one. It is best if you select a tool that provides a dashboard and you can understand effortlessly. With this in mind, even if you are a beginner, you are going to implement the Monitoring service smoothly.
Types of checks
The Monitoring service offers different checks that allow you to understand the state of a service (server). These types of checks examine the UP or DOWN status of the particular service. Moreover, you are notified whenever a check fails. Here are some of the most common types of checks:
- Website HTTP(s): The system sends HTTP(S) requests to a particular web or IP address. As a result, it marks it as UP if the URL response code is 200. You or your administrator can modify the following parameters – the hostname, port, and path.
- Ping (ICMP): This check provides information about the network activity for a particular domain or IP address. The system uses ICMP ping checks to a specific IP address. Then, if a defined percentage of the packets fail, for example, 50%, the check is considered DOWN.
- Transmission Control Protocol (TCP) – The system establishes a TCP connection with the IP address (IPv4 or IPv6) on the chosen port number.
- User Datagram Protocol (UDP) – The system examines the UDP port number you or your administrator chose on the precise IP address.
- Domain Name System (DNS) – The system initiates a DNS query for the hostname your or your administrator chose. Moreover, you can set your preference for the query type on the given IP address.
Why is the Monitoring service important?
The Monitoring service provides complete visibility into all of your network components. That way, you are aware of the overall health of your network. Additionally, such a service helps improve your network reliability by simply indicating if a server is operating or is down. Finally, the Monitoring service is important for you to analyze if a particular component is properly used, overused, and underused.
