How can an alert be added to a host?

The alerts.json file is only to pickup brand new alerts that are not
currently defined in the system. It's more of a way to quickly seed
Ambari with a default set of alerts. If the alert has already been
created, any updates for that alert made in alerts.json will not be
brought in. You'll need to use the REST APIs to update existing
definitions.
You are correct that the agents run the alerts. The definitions.json
file on each agent shows what alerts it is trying to run.

Hi,
I am currently trying to change the alert definitions. I used the
REST api to put a new definition for example for id /30 . I can see
the changes when doing a GET.
Additionaly I replaced the alert.json of the service under
ambari-server and ambari-agent. Still the changes are not reflected
in /var/lib/ambari-agent/cache/alerts/definition.json and I suspect
the alert is not working as expected because of this.
As I undestand the defintions are broadcasted with heartbeats by the
server? And are executed on the host by the agent, where the service
is running? Right?
What am I missing?
Thanks,
Henning
