# Alarm Statistics

The *Alarm Statistics* provides a comprehensive analysis of all alarms that have occurred in a tenant. It allows for a detailed evaluation of alarms by frequency, duration, and severity. This helps to recognize patterns, identify problem sources, and take targeted measures to improve system stability.

In the statistics, various charts and tables can be viewed, including:

* **Alarm distribution by severity** (e.g., High, Medium, Low, Info)
* **Weekly overview** of alarms
* **Alarm heatmap**, which visualizes the distribution of alarms over a period of time
* **Alarm frequency**, which shows which assets trigger alarms most often
* **Alarm duration**, which indicates how long an alarm was active at a time
