Huawei Cloud ASM

Collect metrics and trace data from Huawei Cloud ASM

Configuration¶

Prerequisites¶

Application Service Mesh (ASM) is a service mesh platform launched by Huawei Cloud based on the open-source Istio. It integrates seamlessly with Huawei Cloud's enterprise Kubernetes cluster service CCE.

Before using ASM, you need to have purchased a CCE cluster and installed DataKit on the CCE cluster.

Trace Collection¶

Enable OpenTelemetry Collector¶

Refer to the documentation for accessing the OpenTelemetry collector.

Adjust the ENV_DEFAULT_ENABLED_INPUTS parameter in the ENV module and append the value opentelemetry, as shown below:

- name: ENV_DEFAULT_ENABLED_INPUTS
  value: dk,cpu,disk,diskio,mem,swap,system,hostobject,net,host_processes,container,opentelemetry

Modify Istio Sampling Rate¶

For easier testing, first modify the sampling rate of Istio:

# kubectl edit -n istio-system cm istio-1-15-5-r4
...
sampling: 100   # Change this parameter from the original value of 1 to 100
...

Adjust Otel Endpoint¶

# kubectl edit -n monitoring cm otel-collector-conf
...
exporters:
      apm:
        address: "100.125.0.78:8923"
        project_id: f5f4c067d68b4b3aad86e173b18367bf
        cluster_id: 5f642ce9-4aca-11ee-9dbd-0255ac10024d
      otlp:   # Add new otlp output
        endpoint: "http://datakit-service.datakit:4317"
        tls:
          insecure: true
        compression: none # Disable gzip
...
traces/apm:
          receivers: [ zipkin ]
          processors: [ memory_limiter, batch ]
          exporters: [ otlp ]   # Change exporter to otlp

Metrics Collection¶

Below are adjustments to the DataKit configuration file datakit.yaml.

Enable Prometheus Collector

To enable the Prometheus data collection in DataKit, refer to Prometheus. The configmap is as follows:

  prom.conf: |
    [[inputs.prom]]
      urls = ["http://istiod.istio-system:15014/metrics"] ##istiod address
      uds_path = ""
      ignore_req_err = false
      source = "prom"
      measurement_prefix = ""
      measurement_name = "istio_prom"

Mount Configuration File

        - mountPath: /usr/local/datakit/conf.d/prom/prom.conf
          name: datakit-conf
          subPath: prom.conf

Deploy DataKit

Kubectl apply -f datakit.yml
