How to use metric_relabel_configs on some metrics simultaneously?

I have more 3 metrics

jmx_config_reload_.21830123u_created{namespace="1"} 21389231

jmx_config_reload_.182308912_created{namespace="2"}  283-012

jmx_config_reload_.2312312cd_created{namespace="3"} 98213098

...

I am want in a metric load all metrics, type:

- job_name: 'jmx-exporter'
    static_configs:
      - targets: ['192.168.0.87:109877']
    metric_relabel_configs:
    - source_labels: [__name__]
      regex: jmx_config_reload_.*_created
      target_label: __name__
      replacement: jmx_test_metric_relabel_all
      action: replace

My rule

    groups:
      - name: test of relabeling 
        rules:
        - alert: test of relabeling 
          expr: jmx_test_metric_relabel_all {namespace!=""} ! = 0
          for: 1m
          labels:
            severity: ATENCAO
          annotations:
            summary: test of relabeling 

This procedure not work, because load only first metric.
Please, can someone help me with this situation?
