Monitoring vs Alerting
Monitoring is the process of watching over a component or multiple components in your system, to verify everything is running smoothly. This is done by collecting relevant telemetry data and checking key statistics – such as the mean, median, max, and min – and waiting for one or multiple of them changes unexpectedly. With this process, organizations can report on different metrics and use them to ensure system health and performance are as expected. Monitoring generally includes the following parts:
- Storage
- Aggregation
- Visualization
- Automated Response
Note
Many people get Observability and Monitoring mixed up, as the two share several similarities. However, they are fundamentally different. Observability is the process of evaluating external information to reason about the internal state of a system, while monitoring is a subset of observability which focuses on watching over specific data sources waiting for them to stray from what's expected of them.
Alerting expands on that last bullet – when a monitor witnesses an abnormality, it dishes out an automated response in the form of an alert to the appropriate parties. Monitoring works side-by-side with alerting, as the latter allows teams to define significant situations to manage while relying on software monitoring in changing conditions. In general, alerting does the following tasks:
- Notifies responsible parties
- Triggers programmatic responses
- Messages other concerned personnel when violations, thresholds, or system changes occur
Generally speaking, With monitoring, teams can collect data from their systems' components and use it to detect issues. It allows triggers for alerting, which notifies DevOps teams, enabling immediate resolution. They work together to prevent downtime, improve system performance, and enhance security and operational efficiency.
Here is a table summarizing the difference between monitoring and alerting for better understanding.
Discover how each of these two process work in greater detail in the following section.
How Does Monitoring Work?
Conducting comprehensive monitoring involves several steps. The process mainly includes data collection, analysis, and visualization. Read on and learn the detailed steps of the monitoring process.
1. Data Collection
Monitoring begins by collecting data from multiple system components such as servers, network devices, and databases. This process is done with tools like agents, APIs, and log files, gathering data automatically and continuously to provide insights into the system’s performance and health. Agents later segment the data into metrics and submit them to the monitoring system.
2. Data Analysis
Analyze the collected data to create patterns, visualize trends, and detect anomalies. This step prevents future errors and fosters an accurate and effective system. Machine learning algorithms, correlation analysis, and statistical methods are typically used in this step, depending on organizational needs.
Note
Analysis can be challenging to implement within systems containing several components and large databases. In such cases, leveraging reliable tools like Edge Delta for anomaly detection is most definitely ideal. Edge Delta leverages AI to spot anomalies, troubleshoot quicker, and correlate logs for automated alerting.
3. Visualization
Data is visualized through dashboards that provide real-time insights into system performance. This step is crucial to understanding a system’s real-time performance. Periodic reports summarize the system’s health and performance over time.
4. Continuous Monitoring
Monitoring is a continuous, real-time process that ensures systems are constantly observed. It is crucial to ensure that the system works to improve its purpose. Automated observability platforms facilitate continuous monitoring and quick issue detection, which is why many operators use them in their systems.
However, monitoring can only be effective with proper alerting. Keep reading to understand the entire alerting process.
How Does Alerting Work?
Alerting is a crucial process for ensuring timely responses to system anomalies. Here's a comprehensive guide on how alerting works:
1. Trigger Conditions
Operators are solely responsible for establishing system baselines and finding triggers or relevant events that cause system behavior change. This serves as a starting point for creating an initial alerting configuration. The initial setup defines abnormal conditions by creating thresholds with exceptional metric values configured in the monitoring definition.
2. Alert Generation
The monitoring solution detects the problem or anomaly when the trigger conditions are met. It then generates alerts based on the predefined conditions. These alerts will help the team get notified and mitigate the existing problem.
Pro Tip
You can improve your alerting systems with real-time monitoring, to detect and even predict issues and trigger alerts in real time. These features will simplify your troubleshooting as it provides alerts quicker than other tools.
One example of an alert condition might be when a system detects a sudden drop in database performance, and the team has utilized 90% of its disk space.
3. Notifications
Alerts are communicated to team members via SMS, email, and push notifications. The notification methods and recipients can be customized depending on the severity and type of alert needed. One example of customizing notifications is email configuration alerts for high-severity incidents and Slack notifications for low-severity warnings.
4. Response actions
Upon receiving an alert, immediate actions are taken to investigate and resolve the issue. These actions include restarting, debugging, or troubleshooting the server after receiving an alert. Additionally, all actions and responses are documented for future reference and analysis.
