munin 监控 mongodb
1,下载munin的mongodb插件
https://github.com/erh/mongo-munin
2,安装munin mongodb的依赖
# yum install pymongo
这个插件是python写的,如果不装的话，会报以下错误：
# munin-run mongo_mem
Traceback (most recent call last):
File "/etc/munin/plugins/mongo_mem", line 8, in <module>
import pymongo
ImportError: No module named pymongo
3,安装配置munin mongodb插件
# tar zxvf comerford-mongo-munin-8980f32.tar.gz # cd comerford-mongo-munin-8980f32 # ln -sf /路径/mongo_* /etc/munin/plugins/ # chmod +x /路径/mongo_* # ./build.sh # vim /etc/munin/plugin-conf.d/mongodb //创建文件 [mongo_*] user root //要用root，不然会报错
Can't exec "/etc/munin/plugins/pmongo_mem": Permission denied
4,测试并重启
# munin-run mongo_btree missRatio.value 0 resets.value 0 hits.value 2 misses.value 0 accesses.value 2 # munin-run mongo_conn connections.value 2 # munin-run mongo_docs deleted.value 0 updated.value 0 inserted.value 3 returned.value 0 # munin-run mongo_lock locked.value 0 # munin-run mongo_mem resident.value 39845888 virtual.value 623902720 mapped.value 167772160 # munin-run mongo_ops getmore.value 0 insert.value 3 update.value 0 command.value 43194 query.value 3978 delete.value 0
如果上面都有数据的话，就说明插件安装成功
# /etc/init.d/munin-node restart
