How monitoring helps keep systems running

In today’s digital world, it’s important to keep track of how our technologies are functioning. Monitoring, which involves tracking the status of devices and systems, has become an indispensable part of IT environment management. For the team at CodeArt, it’s part of the gold standard that allows us to keep things under control.

Simply put, monitoring is like a regular health check-up for technology – we check if everything is okay, and if not, we try to solve the problem before it causes “headaches.”

What if we monitor thousands of devices?

Imagine you oversee thousands of electronic kiosks or information panels. Each device is a bit different, even though they all have the same equipment at the start. Their condition changes depending on usage, updates, and external factors like temperature or dust.

To know the status of each device, we use an agent – a small program that collects information. The agent can work in two ways:

• Actively – it sends data to the server on its own
• Passively – it waits for a request from the server

This information helps us understand what is happening and identify potential problems.

What happens to the collected data?

Data from all devices goes to a central server, which processes and analyses it. The server helps us determine if everything is working correctly or if there are situations that require attention, such as:

• Low percentage of free memory
• Exhaustion of connections to the database server
• Processor being overloaded for a long time
• Errors appearing in system logs

Thanks to this, we can act before these problems escalate into major outages.

How do we know something is wrong?

Monitoring alone is not enough. An important part of monitoring is alerts. If something happens, the system immediately notifies us – for example, via email, SMS, or a notification in the communication app we use. The goal is for the right person to learn about the problem in time and be able to solve it.

Custom monitoring

Every IT system is unique, and therefore monitoring must be tailored. At CodeArt, we focus on the client’s needs – we identify what is important to monitor and set up the system to be as efficient as possible.

Well-configured monitoring means fewer problems and more peace of mind for users. And that’s our goal!
