# Alarm statistics

The *Alarm statistics* provides a comprehensive analysis of all alarms that occurred in a project. It enables a detailed evaluation of alarms by frequency, duration, and severity. This helps identify patterns, pinpoint sources of problems, and take targeted measures to improve system stability.

Various charts and tables can be viewed in the statistics, including:

* **Alarm distribution by severity** (e.g. high, medium, low, info)
* **Weekly overview** of the alarms
* **Alarm heatmap**that visualizes the distribution of alarms over a period of time
* **Alarm frequency**that shows which assets trigger alarms most often
* **Alarm duration**that indicates how long each alarm was active
