# Application settings… - Watchdog

Boomerang system often monitors crucial or critical parameters so it is of highest importance to be sure it works correctly. Using a built-in watchdog functionality, all Boomerang services can be monitored by B2WEB server. At start, stop or contact lost a message will be sent via email or SMS.

The Watchdog settings define the monitoring B2WEB server.

Select ‘Use Watchdog’ to start using watchdog.

Enter the watchdog receiver page URL into ‘URL’ field. For example, if B2WEB runs on the same computer then enter ‘<http://localhost/WatchdogReceiver.aspx’>.

Enter site name. The same name must be used during watchdog setup on B2WEB server.

For watchdog to operate correctly, the settings must be adjusted on B2WEB server as described in SG419-0001-B2 ‘ICU Watchdog User Guide’.

## 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://help.boomerang3.com/boomerang-2-system-administrator-manual/menu_-_administration/application_settings_-_watchdog.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.
