# Monitoring by External Systems
If you have a need to monitor the Composable Agentic Platform engine using an external monitoring service, you can include the following line of code in your application status page to determine if the Composable Agentic Platform engine is active:
```java
software.tomorrow.server.Engine.isStarted()
```
For example: The following JSP construct will result in a page that outputs true or false, depending on whether the engine is started or not:
{% code overflow="wrap" %}
```html
Composable Agentic Platform Status
<% // Make sure there is no caching response.setHeader("Pragma", "No-cache");
response.setDateHeader("Expires", 0); response.setHeader("Cache-Control",
"private"); response.setHeader("Cache-Control", "no-cache");
response.setHeader("Cache-Control", "must-revalidate");
response.setHeader("Expires", "Mon, 26 Jul 1997 00:00:00 GMT"); %>
Composable Agentic Platform is
started: <%=software.tomorrow.server.Engine.isStarted()%>
```
{% endcode %}
