The 7 main types of server monitoring

Information technology has greatly improved the efficiency of the modern organization. But this dependence on technology is also a major source of weakness. When systems fail, they can cripple business operations, precipitate massive losses, disappoint customers and users, and inflict substantial damage to a company’s reputation.

This is partly why server monitoring tools are so vital. However, a server is a fairly sophisticated ecosystem with dozens or hundreds of components. Server monitoring is therefore a broad subject that can be broken down into several different areas.

Availability / availability monitoring

Uptime / uptime is the most essential metric in server monitoring. No further action will matter if the server is unreachable or otherwise unavailable. The uptime / uptime monitoring monitors the server to determine if it is turned on and whether it is responding to requests sent to it.

The possible reasons for the unavailability are varied. Maybe a system administrator tripped over a network cable or power cord while in the data center but didn’t notice it, or maybe someone purposely turned the power off server for hardware replacement or maintenance but did not notify users.

Performance monitoring

Monitoring availability is crucial. It is important that your users and clients can access your servers when they need them. However, uptime and uptime are the bare minimum of server monitoring.

Just because users can access your server doesn’t necessarily mean they value their experience. For this you need performance monitoring. Evaluating system performance is about making sure that applications launch quickly and respond to commands as expected.

Resource monitoring

A server is not monolithic hardware. Rather, it is an aggregation of various physical components. The performance of the server as a whole depends on the performance of these individual parts. The most important components of a server for monitoring are the hard drive, RAM, and processor.

Effective monitoring of resources consists of verifying that these resources are not being used to their maximum capacity. It should also be granular and allow you to explore more specific metrics of each resource, such as temperature and voltage. These measures will warn you in advance if the server is at risk of crashing.

Error monitoring

System errors are inevitable. Whether a user entering invalid data, an application failing to save the data to a database, or conflicts between two or more systems, errors will occur. What you should be concerned about is an increase in the number of errors.

The error monitoring software will send an alert to administrators whenever the frequency or nature of errors deviates from the norm.

Log monitoring

The servers generate a system event log. Applications also have their own separate log files that record the events that occur within them. Log files have always been a valuable tool in system troubleshooting, so it should come as no surprise that log monitoring is an important part of server monitoring.

For best results, all operating system and application log files should be stored on a central log server. This speeds up the monitoring process since the software does not need to read logs remotely.

Database monitoring

Data is the oil of the digital age. Large companies like Google and Facebook owe much of their success to their ability to capture, store and / or organize data on the Internet. To a much lesser extent, virtually all businesses in the developed world today hold business data in electronic form. These data are generally stored in databases.

If your server is hosting a database, you need a database monitoring tool that will alert you when there is a risk that the database itself or the data it contains will lose integrity. .

Security monitoring

The types of surveillance we have covered so far deal with issues that arise inadvertently. However, some system issues are caused by deliberate, unauthorized, or malicious actions of users, malware, or third parties. These can put your data, your systems and your business at risk.

The default solution to security issues is install antivirus software. However, antivirus is not always enough to protect your servers. A good security monitoring tool will not only scan for malware, but also pay attention to suspicious system and user activity.

Server monitoring tools are not created equal. Make sure the one you are settling on has the types of features you need.
