Every minute your systems go down without your knowledge results in operational losses and negatively impacts customer trust. In modern business management, anticipating risks and proactively planning for them is the deciding factor in a company's success. Therefore, monitoring cloud and digital systems has become an essential operational pillar that cannot be postponed.

This presents a challenge for companies in choosing the right monitoring tools, especially with the emergence of numerous tools varying in capabilities, technical complexity, and cost.

In this article, we'll explore system monitoring tools and performance alerts, and which one to choose.

What are system monitoring tools? And why are they important?

System monitoring tools monitor the performance of a company's digital infrastructure, including servers, applications, and networks. Their purpose is to detect any malfunctions or performance degradation before they escalate into a real problem that could negatively affect users and operational processes.

These tools operate in two ways:

Reactive monitoring, which alerts you to problems so you can address them as soon as they occur and restore service as quickly as possible.

Proactive monitoring, which detects potential problems and addresses them before they negatively impact performance.

What do these tools actually monitor?

System monitoring tools track key performance indicators (KPIs), including CPU usage, RAM consumption, storage space, network data transfer rate, and other metrics.

These tools can be categorized into four main layers:

Infrastructure layer: This includes server health, temperatures, and hardware resources.

Network layer: This includes data transfer speed, packet loss, and latency.

Application layer: This includes software performance, page load times, and error rates.

Availability layer: This indicates whether the service is up and running, and for how long if it has been down.

Why is this important for users of ERP systems and cloud applications?

Companies that rely on integrated management software, such as accounting, resource management, and inventory systems, manage sensitive operations in real time. Using proactive system monitoring tools means detecting and resolving problems before the user notices them, before the problem occurs and operations are affected.

In other words, every minute of unmonitored downtime in various business systems means delayed invoices, unprocessed orders, and decisions based on incomplete data.

What are performance alerts, and how do they work?

Alerting is the operational tool for system monitoring. While monitoring tools collect and track data, alerting tools transform this data into action. This is achieved through instant notifications sent to the administrator when any indicator exceeds a predefined threshold.

How does a notification system work?

A notification system operates through three steps:

Continuous Monitoring: The monitoring tool processes data periodically (every second or minute).

Comparison: The system compares the detected value with the predefined indicator. For example, if CPU usage exceeds 90% for more than 5 minutes, send an alert.

Notification: The notification tool sends an alert via a predefined communication channel to prompt action.

Common Notification Channels

Email: For sending warning and non-urgent alerts.

Phone call or SMS: For emergencies outside of business hours.

Slack: For immediate coordination among team members.

Webhook: Used for integration with other systems and to automatically send data from one application to another in case of a malfunction.

Alerts in notification tools are divided into three main categories:

Critical alerts: These indicate that the service has already stopped or that a disaster is imminent, requiring immediate response.

Warning alerts: These indicate that the system is functioning but is approaching a critical point, necessitating monitoring and intervention to prevent system failure.

Logs: These do not indicate a problem but rather an event that was successfully completed. Actions are recorded for later reference.

Criteria for Selecting the Right System Monitoring and Performance Notification Tools
Choosing the right tool should be based on several criteria to ensure it aligns with your business nature and future expansion plans. These criteria include:

Clearing the Objective Before Choosing the Tool
Before selecting from among monitoring tools, you must first define the purpose of using them. This can be done by answering the following questions:

What systems need monitoring? (Servers, applications, databases, network?)

What are the critical performance indicators for your business?

Who is responsible for receiving alerts and taking the necessary actions?

Compatibility with Existing Infrastructure
Compatibility with existing business systems is one of the most important criteria for selecting a tool. Therefore, you must ensure that the tool supports the technologies and platforms your business already relies on, in addition to its ability to integrate with various business tools.

Scalability
The selected monitoring tool should be capable of growing with your infrastructure and future goals to avoid any performance issues or the need for rebuilding during expansion. Among the most important factors that must be present in this current system are:

Support for easily adding new servers and services.

No impact on performance when the volume of monitored data increases.

Ease of use. The user interface must be clear and easy to navigate, and capable of reducing the time and effort required to perform tasks. Additionally, training should be provided to the team to learn how to use the tool's control panels.
