Top 10 Popular Server Monitoring Tools

Overview of Server Monitoring Tools:

In today’s busy world, any business requires strong infrastructure, well-established network connections, powerful servers to handle loads of users or transactions, etc., to succeed in their business.

Let's imagine that your business is running smoothly but suddenly one server, a service or an application gets down or is crashed due to overload. What would be your reaction? What would be the impact of such downtime on your business, customer, service, etc?

This downtime will cost your business and it will impact productivity as well as service which may damage your reputation in the market.

Server Monitoring Tools

Hence when the question arises on how you can keep your server running without any issue and make your client/customer happy?

The answer to this will be Server Monitoring.

  • Server Monitoring means continuously monitoring or scanning the available servers in the network and detecting any failure in the server or network
  • Server Monitoring is a preventive action which detects any failure before it causes some major issue to the network system
  • Server monitoring includes monitoring the performance of applications, web services, IT Infrastructure etc.

Server Monitoring is required to ensure if your server is running and the business transactions are getting saved as per the flow. Any crash, failure or downtime in the server causes huge loss to the business and the market reputation, so server monitoring is crucial to avoid all such downtime.
