Influence how Health Log Analytics generates and prioritizes alerts and identifies anomalies. Use alert filters to reduce noise from unimportant issues.

## Overview of impacting alert generation, prioritization, and anomaly detection {#hla-controlling-alert-generation__cf-using-parent-workflow}

Explore how to influence alert generation and anomaly detection in Health Log Analytics. You can create and modify rules to generate alerts for specific metrics, ensuring that you're informed of important issues. You can also assign different levels of significance to alerts,
helping Health Log Analytics prioritize them based on their relevance. In addition, you can influence anomaly detection by managing the keywords that Health Log Analytics looks for in your log data, and use advanced log alert filters to reduce noise.

* [Using alert rules to control when Health Log Analytics generates alerts](https://www.servicenow.com/docs/ymNBguZzXBjp1JDEBvAVFQ "Alert rules enable you to set conditions that determine when Health Log Analytics (HLA) triggers an alert.")

  Manage alert rules to generate Log Analytics alerts for specified metrics.
* [Assign higher or lower significance to an alert in Health Log Analytics](https://www.servicenow.com/docs/X7k4RHU90IWe6XU1uwhDZw "Label an alert in Health Log Analytics as meaningful or insignificant, or restore normal importance to the metric involved in generating it.")

  Assign higher or lower significance to an alert to help prioritize the alerts that Health Log Analytics generates.
* [Influence anomaly detection in Health Log Analytics with lexical keywords](https://www.servicenow.com/docs/zv1lXI_IsKcRfWG_jaeqIg "Influence how Health Log Analytics finds anomalies by managing keywords it looks for in your log data. When text in log data for a source matches a lexical keyword that exceeds a specified count threshold, the system identifies an anomaly and generates an alert.")

  Influence how Health Log Analytics finds anomalies by managing keywords it looks for in your log data.
* [Reduce noise by adding advanced log alert filters](https://www.servicenow.com/docs/HHwckgGdrYi8pg85ulCWDg "Use advanced log alert filters to determine whether to allow an alert or to drop it. These filters reduce noise by dropping alerts that don't indicate a significant issue.")

  Use advanced log alert filters to reduce noise by making Health Log Analytics drop alerts that don't indicate a significant issue.
