# Alarm statistics

The *Alarm Statistics* provides a comprehensive analysis of all alarms that have 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.

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

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

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.buildings.ability.abb/collection/english-v14/documentation/alarme-regeln-und-eskalationen/alarme/alarmstatistik.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
