Your web servers deliver essential services to potentially millions of worldwide customers. You and your customers rely on the web servers for the delivery of those essential services. Web server monitoring allows instant visibility and enables you to keep a check on the health and performance of your web servers. This in turn allows you to
- take remedial action in case of hardware or software failure, and
- to take proactive action in case the hardware or software is overloaded and needs upgrades or replacements.
With web server monitoring, you get timely notifications that enable you to take timely action, which keeps the web servers up and running for delivering optimal performance for end users.
Services delivered over the Internet are usually not run from a single web server. For best performance, load balancing and to reduce load time, service providers deploy web servers at multiple locations so that you get service from the server nearest to you. Web server monitoring allows you to monitor essential performance metrics – such as load time and latency – for your regional and global web server deployments.
Web server monitoring also helps you determine which of your websites and web-based services are growing in popularity, i.e., user requests. You can then plan for scaling your websites and making other changes that will help you cope with the increased demand.
The same is also true for websites whose popularity is decreasing. With web server monitoring, you can identify and eliminate problems – such as increased load times – that cause your users to switch to other services.
If your web servers are not monitored, then you lack visibility into their health and performance. You don't know if the web servers are performing as required, or if users are suffering due to the poor performance of the servers. This can lead to degraded performance or service unavailability. Possible short-term consequences could be bad customer experience, leading to loss of customers and revenue. Possible long-term consequences could be loss of reputation, leading to lack of business viability.
