结合Ansible技术监控Storm集群

linre

1、我的hosts配置
# vim /etc/hosts

1 2 3 4 5 6 7 8 9 10 11 12

192.168.1.100  storm_zk1 192.168.1.101  storm_zk2 192.168.1.102  storm_zk3    192.168.1.103  storm_nimbus    192.168.1.104  storm_supervisor1 192.168.1.105  storm_supervisor2 192.168.1.106  storm_supervisor3 192.168.1.107  storm_supervisor4 192.168.1.108  storm_supervisor5 192.168.1.109  storm_supervisor6

2、我的storm配置
# vim /usr/local/storm/conf/storm.yaml

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70

3、nimbus节点部署
# vim /data/scripts/monitor_status_for_storm.sh
