一.介紹jquery
agent用於採集機器負載監控指標，好比cpu.idle、load.1min、disk.io.util等等，每隔60秒push給Transfer。agent與Transfer創建了長鏈接，數據發送速度比較快，agent提供了一個http接口/v1/push用於接收用戶手工push的一些數據，而後經過長鏈接迅速轉發給Transfer。git
二.部署github
agent須要部署到全部要被監控的機器上，好比公司有10萬臺機器，那就要部署10萬個agent。agent自己資源消耗不多，不用擔憂。web
1>.部署環境json
2>.拷貝agent工具包到須要安裝的服務器上bootstrap

./open-falcon start agent 啓動進程 ./open-falcon stop agent 中止進程 ./open-falcon monitor agent 查看日誌 看var目錄下的log是否正常，或者瀏覽器訪問其1988端口。另外agent提供了一個--check參數，能夠檢查agent是否能夠正常跑在當前機器上 ./falcon-agent --check

三.在open-falcon中的前端界面查看是否有對應的主機列表
1>.刷新前端頁面，會看到2臺監控的主機信息，以下圖所示：
2>.以Endpoint視角查看agent採集的監控項目
3>.點擊後可查看到的視圖信息以下：
