Anomaly Detection

Anomaly detection is the process of identifying unexpected events or observations that deviate significantly from the norm. It is also known as outlier detection or analysis.

An anomaly detection system helps predict service degradation in an increasingly complex IT environment using AI- and ML-powered insights. Obtain unparalleled visibility into performance challenges and reduce your mean time to repair (MTTR) using Site24x7's AI-powered monitoring tool.

Anomaly detection using machine learning and AI

AI- and ML-powered anomaly detection connects different data points using critical algorithms, understands the trends and seasonality, and identifies issues in real-time. Site24x7's AI-powered monitoring for DevOps and IT operations provides the following benefits:

Proactive alerting of rogue resources

Real-time detection of deviation or unusual spikes in performance metrics helps you maintain the health of your services and stay ahead of downtime.

Simplify root cause analysis (RCA)

Identify dependencies between individual variations in performance metrics and various monitor types making it simpler to identify the origin of the issue that led to the chain of downtime occurrences.

Auto-aligning monitor behavior from dynamic environments

Overcome the limits of static thresholds to reduce false alerts in your dynamic environment. Automatic learning helps the system build a reliable baseline for performance without manual intervention.

Anomaly detection across all facets of monitoring

Discover regional response time degradation in your website

A response time spike can be limited to a single, specific region due to issues with the ISP or the CDN. Narrow down the scope of the issue with region specific details and quickly avert potential disasters.

Anomaly detection to find DoS - Site24x7

Detect denial-of-service (DoS) attacks

Aberrations in an application's request throughput and data throughput parameters indicate a possible DoS attack on your website. Identify threats the moment they start, and avoid damage to your website and brand image.

Identify slowed down website connections and applications

Identify increase in connection time values to pinpoint delays in connections to the web server. Connection time of a website is a crucial parameter to keep an eye on. A slow request will affect all the requests following it in the queue, resulting in connection time out errors. This can also affect the overall performance of the application.

Anomaly detector to detect slowed down connections - Site24x7

Site24x7 helps us to spot abnormalities quickly. We see how some equipment has been behaving and how they might change. Site24x7 has helped us see how issues evolve. It predicts and lets us know what resources will be required the following week. It is a pretty powerful and useful tool and has decreased our manual efforts greatly.

Anomaly Detection FAQ

What are anomalies?

An anomaly is something that deviates from the norm. It is a data point that differs from other observations. Anomalies are also known as outliers. Anomalies can occur in databases and servers. In terms of monitoring, an anomaly is a significant deviation from how a metric usually behaves or behaved in the past. Anomalies could be a sudden spike in website traffic, a steep rise in application response time, or a slowed-down website connection.

What is anomaly detection?

Anomaly detection is the process of identifying any deviation from normal behavior. It could be an indication of a technical glitch or a potential loophole for attacks. With IT monitoring, anomaly detection is when a metric behaves differently when compared to how it generally behaves or how it behaved in the past.

Anomaly detection takes into account seasonal trends including certain times of day, days of the week, and months of the year during which any deviation from the norm is typical. It is critical in areas where anomalies are less likely to happen and when recurring patterns are not easy to monitor without proper anomaly and threshold-based alerting in place.

How does AI and ML help in anomaly detection?

The AI and ML engine studies behavior over a prescribed period to understand regular patterns. Based on these insights, it identifies when there is a deviation from the observed behavior and notifies you about it. The AI and ML engine also predicts future trends based on these observations.

Why do websites need an anomaly detection system?

Websites have a lot of technologies behind them that can go wrong. From Javascript errors to HTML errors, plugins, CDN issues, and SSL websites are prone to multiple errors. Internet ISP issues that you do not have much control over can also occur. Besides, new standards and technologies to keep up with can make it more overwhelming. So an automated anomaly detection system that can give insights scanning all these parameters can help.

How does Site24x7 help with anomaly detection?

Site24x7's AI-powered anomaly framework uses the Robust Principal Component Analysis (RPCA) and matrix sketching algorithms to detect anomalies. Site24x7's anomaly detection tool involves mathematical modeling, anomaly event generation, and domain scoring.

It identifies major anomalies in website speed, application response time, web server connection delay, server memory and disk metrics, network bandwidth utilization, and key AWS performance metrics. The AI and ML engine studies the common patterns—taking into account seasonal trends—and generates alerts whenever an anomaly is observed. Site24x7 also allows you to configure anomaly-based thresholds and receive alerts through email, voice call, SMS, or your third-party ITSM tool.
