Syslog messages provide crucial insights into the health, performance, and security of a system. To help you prioritize and understand these events, syslog messages are categorized by severity levels. This categorization is essential for effective monitoring, troubleshooting, and incident response. Understanding and properly configuring Syslog message severity levels are fundamental for effective system administration. It allows organizations to filter out noise, focus on critical events, and implement automated alerts based on the severity, ensuring timely responses to potential threats and operational issues.
The different syslog message severity levels are as follows:
Informational System Log Messages. These messages are not critical and provide routine announcements of events, such as configuration changes. These messages help you track the behaviour of the system.
Low Severity System Log Messages. These messages represent minor issues that might not need immediate attention but are worth noting.
Medium Severity System Log Messages. These messages indicate issues that are slightly more significant than the low severity ones, yet are not very critical. They might not lead to any immediate crisis, but are worth noting for timely investigation to prevent critical failures.
High Severity System Log Messages. These messages indicate that something has gone wrong and needs immediate attention. While the entire system might not be down, a specific function or area is clearly experiencing difficulties, and it needs to be fixed to ensure everything runs smoothly.
Critical Severity System Log Messages. These messages are the alarms that signify a major crisis has occurred. These messages demand immediate and urgent action.
