I add a metric to /config/oal/my.oal but see nothing

My sw is 8.9.1 and I add a metric to /config/oal/my.oal like this:
my_endpoint_cpm = from(Endpoint.*).cpm();
Then, reboot the OAP server, but when I query data use graphql I get nothing, I also do not see the index in elasticsearch.

btw, I query ok when use endpoint_cpm metric:

In current ElasticSearchstorage, there is no point to create new index. This metric is a new metric in the cpm index.
Also, your GraphQL is not using your new metric name, what do you want to see?

[wu-sheng]

What do you mean you can't? You need to enter after changing metric name.

I am sorry I did not explan it cleanly. Of caurse I enter the new name my_endpoint_cpm, but after I enter the name, the select field that my picture point out is empty and has no options. Then I saved the setting and the chart is show nothing.

This seems like the backend doesn't have this metric. I doubt you could find this metric in sw_metrics-cpm-xxx. That index would includes all metrics using cpm function, you have to find metric-name= my_endpoint_cpm.

From my understanding, either your OAL script is never loaded, or there is some booting stage error, but you ignored.

Finally, I put the statement in the config/oal/core.oal and it works.
This days I put the statement in the config/oal/my.oal which created by myself, and it did not work!

Oh, you can't add a new OAL script w/o code changes. They are read through codes.
