zabbix3.4監(jiān)控zookeeper

zookeeper監(jiān)控要點系統(tǒng)監(jiān)控 這個監(jiān)控linux系統(tǒng)以及修改linux服務(wù)器參數(shù)即可
內(nèi)存使用量 ZooKeeper應(yīng)當完全運行在內(nèi)存中，不能使用到SWAP。Java Heap大小不能超過可用內(nèi)存。
Swap使用量 使用Swap會降低ZooKeeper的性能，設(shè)置vm.swappiness = 0
網(wǎng)絡(luò)帶寬占用 如果發(fā)現(xiàn)ZooKeeper性能降低關(guān)注下網(wǎng)絡(luò)帶寬占用情況和丟包情況，通常情況下ZooKeeper是20%寫入80%讀入
磁盤使用量 ZooKeeper數(shù)據(jù)目錄使用情況需要注意
磁盤I/O ZooKeeper的磁盤寫入是異步的，所以不會存在很大的I/O請求，如果ZooKeeper和其他I/O密集型服務(wù)公用應(yīng)該關(guān)注下磁盤I/O情況

ZooKeeper監(jiān)控
zk_avg/min/max_latency 響應(yīng)一個客戶端請求的時間，建議這個時間大于10個Tick就報警 平均延遲/最小延遲/最大延遲
zk_outstanding_requests 排隊請求的數(shù)量，當ZooKeeper超過了它的處理能力時，這個值會增大，建議設(shè)置報警閥值為10 堆積請求數(shù)
zk_packets_received 接收到客戶端請求的包數(shù)量 收包數(shù)
zk_packets_sent 發(fā)送給客戶單的包數(shù)量，主要是響應(yīng)和通知 發(fā)包數(shù)
zk_max_file_descriptor_count 最大允許打開的文件數(shù)，由ulimit控制 最大文件描述符數(shù)量
zk_open_file_descriptor_count 打開文件數(shù)量，當這個值大于允許值得85%時報警 打開的文件描述符數(shù)量
Mode 運行的角色，如果沒有加入集群就是standalone,加入集群式follower或者leader
zk_followers leader角色才會有這個輸出,集合中follower的個數(shù)。正常的值應(yīng)該是集合成員的數(shù)量減1 follower數(shù)量
zk_pending_syncs leader角色才會有這個輸出，pending syncs的數(shù)量 準備同步數(shù)
zk_znode_count znodes的數(shù)量 znode數(shù)量
zk_watch_count watches的數(shù)量 watch數(shù)量
Java Heap Size ZooKeeper Java進程的
