how to use process functon in MAL

[devin-wanghuixiong]

meter toolkit:

counter = MeterFactory.counter("biz_count")
                        .tag("schema", "s1")
                        .tag("module", "m1")
                        .tag("operation", "create")
                        .tag("result", "C0909")
                        .mode(Counter.Mode.INCREMENT)
                        .build();
counter.increment(1D);

add layer in server-core

CUSTOMER(101, true);

MAL:

expPrefix: tag({tags -> tags.service = tags['schema']}).tag({tags -> tags.instance = tags['module']}).tag({tags -> tags.layer='CUSTOMER'})
expSuffix: process(['service'], ['instance'], ['operation'], 'layer')
metricPrefix: meter_process
metricsRules:
  # 总请求数
  - name: biz_count
    exp: biz_count.sum(by=['service','instance','operation', 'layer']).increase("PT1M")

UI config

problem：no data in PROCESS

As this is your customization, you need to check the data flow step by step.

We can't tell just from guessing.

The layer's services have been detected, and I can see them through the dashboard list.

[wu-sheng]

You hijacked the layer. I don't think official UI supports that layer.

[devin-wanghuixiong]

I just added a custom layer to the source code and created custom dashboards for this layer.
Do I need to modify the source code to display custom dashboards in the menu? Can't you just modify the menu.yaml configuration file?

[wu-sheng]

I don't know whether it can or can't. I didn't do that before.

[devin-wanghuixiong]

thank you！
It seems that I need to study the source code to try to solve this problem.
