Kubernetes上的Telegraf :错误:服务"telegraf“无效: spec.ports:必需值

Question

我想做什么？

我试图在我的Kubernetes集群中部署telegraf，以便我可以使用telegraf的Prometheus输入插件从特定的URL读取数据(度量)，并使用telegraf的输出文件插件将这些度量写入文件中。

我做了什么？

我使用telegraf 舵图在kubernetes上部署telegraf。我更改了以下配置更改。原始telegraf文件：

config:
  agent:
    interval: "10s"
    round_interval: true
    metric_batch_size: 1000
    metric_buffer_limit: 10000
    collection_jitter: "0s"
    flush_interval: "10s"
    flush_jitter: "0s"
    precision: ""
    debug: false
    quiet: false
    logfile: ""
    hostname: "$HOSTNAME"
    omit_hostname: false
  processors:
    - enum:
        mapping:
          field: "status"
          dest: "status_code"
          value_mappings:
            healthy: 1
            problem: 2
            critical: 3
  outputs:
    - influxdb:
        urls:
          - "http://influxdb.monitoring.svc:8086"
        database: "telegraf"
  inputs:
    - statsd:
        service_address: ":8125"
        percentiles:
          - 50
          - 95
          - 99
        metric_separator: "_"
        allowed_pending_messages: 10000
        percentile_limit: 1000

我对它所做的修改：

config:
  outputs:
    - file:
        files:
          - "stdout"
          - "metrics.out" 
        data_format: influx  
  inputs:
    - prometheus:
        - urls:
            url: "http://ipaddr:80/metrics"

当我应用舵图时，我得到了错误:服务"telegraf“无效: spec.ports: Required value和部署失败。

chandhana@Azure:~/clouddrive/PromExpose$ helm install telegraf influxdata/telegraf -f telegraf-values.yaml
Error: Service "telegraf" is invalid: spec.ports: Required value

如果我在更改YAML配置上有任何错误，请帮助我，因为我没有为telegraf的输入和输出插件的yaml格式找到任何资源。参考附加链接：电传.conf文件

您忘了在values.yaml中启用度量，默认情况下它是禁用的。正确部分是

metrics:
  health:
    enabled: true
  collect_memstats: false

将telegraf-values.yaml更改为

config:
  agent:
    interval: "10s"
    round_interval: true
    metric_batch_size: 1000
    metric_buffer_limit: 10000
    collection_jitter: "0s"
    flush_interval: "10s"
    flush_jitter: "0s"
    precision: ""
    debug: false
    quiet: false
    logfile: ""
    hostname: "$HOSTNAME"
    omit_hostname: false
  processors:
    - enum:
        mapping:
          field: "status"
          dest: "status_code"
          value_mappings:
            healthy: 1
            problem: 2
            critical: 3
  outputs:
    - file:
        files:
          - "stdout"
          - "metrics.out" 
        data_format: influx 
  inputs:
    - prometheus:
        - urls:
            url: "http://ipaddr:80/metrics"

metrics:
  health:
    enabled: true
  collect_memstats: false

结果：

helm install telegraf influxdata/telegraf -f values.yaml
NAME: telegraf
LAST DEPLOYED: Fri Jun 25 10:35:05 2021
NAMESPACE: default
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
To open a shell session in the container running Telegraf run the following:

  kubectl exec -i -t --namespace default $(kubectl get pods --namespace default -l app.kubernetes.io/name=telegraf -o jsonpath='{.items[0].metadata.name}') /bin/sh

To view the logs for a Telegraf pod, run the following:

  kubectl logs -f --namespace default $(kubectl get pods --namespace default -l app.kubernetes.io/name=telegraf -o jsonpath='{ .items[0].metadata.name }')
