10 Log Analysis Tools in 2022
Log analysis is a part of a bigger set of practices called and often uses the help of AI or Machine Learning algorithms to properly interpret and process log data coming in. Since logs come from multiple sources, there are a lot of issues emerging such as different formatting and standards, absent or surplus data and more.
How Does Log Analysis Work?
You need to make sure that you can extract the correct data from your logs and then further analyze, monitor and visualize them. In order to do that you need to:
- Collect data from multiple sources
- Centralize logs in one platform
- Make your logs searchable by indexing them
- Search for patterns and Analyze Query outcomes
- Set up Monitoring and Alerting
- Report and Dashboard
Main Uses of Log Analysis:
There are multiple reasons why should you have a log analysis tool set up.
Log analysis is often performed in order to:
- Ensure compliance with audits, regulations, and/or specific security policies
- System troubleshooting
- Security incident response and investigation
- Real User Behavior Analysis
There any many more uses for log analysis outside of the usual public market, such as official investigations and forensics.
10 Best Log Analysis Tools and Software in 2022
Now that we’ve established the basics, it’s time to look at the best log analysis software in 2022. Most of these tools offer a complete log management solution and range from open-source and freemium, all the way to enterprise-ready solutions.
Logtail is a complete log management solution from Better Stack, allowing you to collect, transport, analyze, monitor, store, and archive logs from all over your cloud architecture.
By offering integrations into stacks like Kubernetes, Heroku, Logstash, Rails, Docker, or AWS, and more, you get a broad array of options for monitoring. Thanks to custom-built technology and data stored in ClickHouse, you can work with your logs more efficiently and save funds. All the collected data are sent to Grafana for comprehensive visualization and more efficient intel management.
Logtail allows you to query your logs the same way you'd query your database with SQL-compatible structured log management. Logtail allows you to search & filter petabytes of logs in a moment and set an anomaly detection alert to receive alerts when your logs become out of the ordinary.
One of the greatest benefits of Logtail is built-in collaboration features, where you can cooperate with your colleagues in a google docs-like environment, save, share, and archive parts of code, and collaborate with your colleagues.
Tighter security is one of the main benefits of log monitoring, and Logtail itself is one of the most secure tools available. Using industry-standard best practices and cooperating only with data centers compliant with DIN ISO/IEC27001 certifications, your data is safe during both transit and storage.
Main Benefits of Logtail:
- Inexpensive and extremely efficient ClickHouse based tool
- Integration with Better Uptime, enabling even better observability
- Pricing starts at $0.25
Dynatrace offers Log Management as a part of their platform. It allows you to create custom log metrics for smarter and faster troubleshooting and understanding logs in context. Their Log Management solution offers Log data analysis and alerting. Dynatrace allows you to analyze log events across different parts of production and over longer periods of time. Dynatrace leverages artificial intelligence to correlate log messages and problems your monitors register. All of the data is used for root-cause analysis. You can also define custom rules and log metrics to receive notifications if any anomalies or passed thresholds occur. Dynatrace offers two products, Log monitoring v1 and Log monitoring v2 modes and they offer different approaches to log management, whereas the v2 is considered by Dynatrace as newer. V2 removes issues with logs with unrecognized timestamps and offers a generic log data ingestion engine. However, a lot of features are still missing in the v2, such as sensitive info masking, UI configuration files on a host, or on-demand access to log files on the monitored host. Dynatrace also offers a quite unique pricing model based on the Davis data units, also known as DDUs. Basically, each log record (line, message, entry) deducts 0.0005DDU from your available quota - 1 million log records multiplied by a DDU weight of 0.0005 consume a total of 500 DDUs.
Main Benefits of Dynatrace:
- 2 different products are available (v1 and v2)
- Dynatrace is an All-in-one platform
