Suppress Your Data!
Blog post from PagerDuty
In incident management, suppression is a crucial technique used to manage the overwhelming volume of alerts generated by modern infrastructure, ensuring that high-priority alerts receive the necessary attention while preventing alert fatigue among admins. Rather than permanently deleting data, suppression temporarily withholds certain alerts from appearing on priority dashboards, allowing admins to focus on actionable incidents. This approach can be nuanced, with configurations allowing for alerts to be suppressed or reported based on criteria like frequency, time of day, or device type. Importantly, suppression does not entail data loss; suppressed alerts are still recorded and can be reviewed as needed, contributing to historical data analysis and allowing for better tuning of alerting thresholds. This method enhances the efficiency of incident management by reducing noise without sacrificing the visibility of critical infrastructure events.
