10 Best Log Monitoring Tools in 2022
There is no doubt that logging your system's activity is essential for its proper function. Logs can give you insight into occurring problems and help you understand how your software performs over time, where it excels, and where it fails.
When every aspect of the infrastructure logs on its own, you can easily have dozens of individual logs to look after, which is nearly impossible - that's why it's always good to use Log monitoring tools.
Having multiple log sources is inevitable but storing and analyzing them independently is impractical. Centralized logging allows you to oversight multiple log sources at once by:
- Log collection and transport - To get real-time insight into logs, you need to transport logs using either an API or by configuring individual loggings to log directly into the centralized log manager. At the same time, you need to think about packet loss and how to prevent it.
- Log storing - Considering data volume and retention period is important when picking a monitoring solution.
- Log analysis - Comprehensive analysis of individual logs depends on properly distributing them into categories, visualization, and understanding reoccurring patterns or developing trends. This can also help you to baseline your software and set thresholds for other monitors. A lot of this is nowadays handled by AI.
- Alerting - After setting thresholds and understanding your software's behavior, you can integrate your monitoring solution with common tools. This way, you will be instantly alerted if anything goes south.
Log monitoring is also used in other monitoring practices such as:
- Server Monitoring
- Network Monitoring
- Application Monitoring
- Database Monitoring
- Cloud Monitoring
.. and more
