Why Skywalking can‘t show the adress of the Linux when I use the feature of Linux Monitoring?

[BoydenYubin]

The vm instance shows the vm:null

• Docker: => Runing the lastest version of skywalking-oap-server and same version of skywalking-ui cotainer
• Raspberry => The linux system to be watched (node_exporter and collector)

We can find all the metric data in the ui, but can't the real ip of the linux system
The vm.yaml will be as as below:

filter: "{ tags -> tags.job_name == 'vm-monitoring' }" # The OpenTelemetry job name
expSuffix: tag({tags -> tags.node_identifier_host_name = 'vm::' + tags.node_identifier_host_name}).service(['node_identifier_host_name'])
metricPrefix: meter_vm
metricsRules:
  ......

UI shows the null name of the system as below:

1. Use the latest release. 8.x is EOF
2. Choose the same version OpenTelemetry in the e2e or showcase. OTEL collector usually has inconsistent behaviors across versions, you have to manually check tags if you choose another version.

Showcase provides Linux monitoring demo setting out-of-box. All things are there.
