Can I see failing services across all my hosts?

Yes! Use the `list_all_monitored_services` tool. The agent will return a comprehensive list of services, and you can ask it to filter for those in CRITICAL or WARNING states.

How do I apply changes I made in WATO through the agent?

Use the `activate_checkmk_changes` tool. Your agent will trigger the activation process in Checkmk, pushing all pending configurations to the monitoring core.

Where do I find my Checkmk Automation Secret?

Log in to your Checkmk site, go to 'Setup' -> 'Users', and edit your automation user. You will see the 'Automation secret' field there.
