讓Heapster和InfluxDB進行溝通

我正在試圖讓Heapster/InfluxDB/Grafana在Kubernetes集羣上成立。看起來Heapster正在生成數據，但沒有將它發送到InfluxDB。當我看到了Heapster吊艙內的eventer容器容器日誌，日誌是這個樣子：讓Heapster和InfluxDB進行溝通

之後，但只是一系列事件被導出。我的第一個問題是Heapster是否成功連接到InfluxDB服務，或者它只是發送數據到http://monitoring-influxdb:8086，假設將收集一些東西？如果確實連接了，爲什麼我的InfluxDB中的k8s數據庫是空的？

我在kubernetes/contrib/ansible中使用安全腳本部署了我的集羣，yaml文件是從somwhere下載的（我不知道在哪裏）。如果你想看看，我推送他們到一個git倉庫here。

如何安裝heapster/influxDB？ yaml定義是什麼樣的？或者你是否通過k8s插件管理器安裝？ – fishi

我剛更新了這個問題，謝謝。我使用了一個可靠的腳本來部署kubernetes，腳本下載了一組yaml文件。然後我將這些yaml文件應用於'kubectl apply -f' – Ryan

確定是否收集數據的最簡單方法（IMO）是查看influxdb的日誌。在我的環境（從https://github.com/kubernetes/heapster/tree/master/deploy/kube-config/influxdb部署），豆莢都在KUBE-系統命名空間：

kubectl get pods -n kube-system 
NAME         READY  STATUS RESTARTS AGE 
heapster-603813915-tggbr    1/1  Running 0   34d 
kubernetes-dashboard-3313488171-mpn5b 1/1  Running 2   43d 
monitoring-grafana-2175968514-zxgn1  1/1  Running 0   34d 
monitoring-influxdb-1957622127-92r2w 1/1  Running 0   34d

和日誌：

kubectl logs monitoring-influxdb-1957622127-92r2w -n kube-system

204個回答非常明確，它在這種情況下接受數據。如果由於某種原因您的堆棧器未與influxdb通信，那麼答案可能也在influxdb堆棧的日誌中。

謝謝。在開始討論之後，看起來influxdb正在將數據作爲一系列數據獲取，但不會將其保存到數據庫中。這是我會繼續研究的 – Ryan
