问题

客户说keystone端口总在zabbit中报错:

net.tcp.service.perf[http,,35357] 
({host1:net.tcp.service.perf[http,,35357].count(#3,0)}=3 & {host2:net.tcp.service.perf[http,,35357].count(#3,0)}=3) | {host1:net.tcp.service.perf[http,,35357].prev(0)}>15 | {host2:net.tcp.service.perf[http,,35357].prev(0)}>15 
net.tcp.service.perf[http,,5000] 
({host1:net.tcp.service.perf[http,,5000].count(#3,0)}=3 & {host2:net.tcp.service.perf[http,,5000].count(#3,0)}=3) | {host1:net.tcp.service.perf[http,,5000].prev(0)}>15 | {host2:net.tcp.service.perf[http,,5000].prev(0)}>15 

改成下列的配置可能会减小误报:

net.tcp.service.perf[http,,35357] 
({host1:net.tcp.service.perf[http,,35357].max(#3)}=0 & {host2:net.tcp.service.perf[http,,35357].max(#3)}=0) 
net.tcp.service.perf[http,,5000] 
({host1:net.tcp.service.perf[http,,5000].max(#3)}=0 & {host2:net.tcp.service.perf[http,,5000].max(#3)}=0) 

Zabbix是什么? 我不是做运维的, 之前从来没有用过也没有听说过这个名词. 好吧, 学吧. 另外, 我发现网上安装zabbix的文章一搜一堆堆的, 但没有一篇照着是可以顺利安装成功的, 包括官方文档, 总共遇到了下列4个错误:

1. ‘Table ‘users’ already exists’
2. Job for zabbix-server.service failed because a configured resource limit was exceeded.
3. Cannot connect to the database.
4. Zabbix server cannot work with a Zabbix proxy database

所以我还是将这么个玩意也写篇博客吧. Zabbix是一个监控软件, Zabbix 3.0中提供的监控方式包括：
- Active agents
- Passive agents
- Extending agents
- Simple checks
- SNMP agents
- Zabbix Internal checks
- Zabbix trapper
- IPMI agents
- JMX agents
- External checks
- Database monitoring
- SSH agents
- Telnet agents
- SNMP Traps
- Aggregate checks
- Calculated checks

Configuration -> Templates -> Create Host
Click this host, and select the monitor template, eg: Template OS Linux 
How to Define template(http://blog.51cto.com/ywzhou/1579917), 'Configuration -> Templates', 
 - create 'Item' for this template, eg: net.tcp.service.perf[tcp,192.168.99.216,7070]
 - create 'Trigger' for this template
 - create 'Graph' for this template, it will link to 'Item'
 - Link template to Host
