items can be used in alarm-setting.yaml

[Simbafa]

In the example alarm-setting.yaml file, only oal items are used.
I want to know if other items, for example, items from otel can be used or not.
Thank you very much!

otel is not the data in the storage. all metrics of otlp are processed through MAL, so the names in your MAL scripts can be used in alarm process.

@wu-sheng
Thank you very much for the informaiton.
could you please provide an example?
Thanks in advance!

What example? It is just a name in the MAL script. Many of these files could be found in your /config folder, e.g. https://github.com/apache/skywalking/blob/master/oap-server/server-starter/src/main/resources/otel-rules/activemq/activemq-broker.yaml

I add following contents into alarm-setting.yaml, oap starts failed.
What's the error in the config?

		  node_memory_rule:
		    expression: k8s_node_memory_usage/k8s_node_memory_total >0.7 
		    period: 5
		    message: Node {node} memory usage > 0.7.

Something fails, then you need to read the logs? Don't rely on my guessing.
