Q：有没有已经实施的案例
A：

Q：check-mk-agent怎么安装？
A：
使用epel源，yum -y install check-mk-agent xinetd && /etc/init.d/xinetd start && chkconfig xinetd on，同时开放tcp:6556端口，目前epel源最高版本 1.2.6p16-3.el6
Q：客户端获取应用监控信息，如mysql等
A:
放置在/usr/share/check-mk-agent/plugins目录，如果需要异步的话，在plugins目录新建以秒为名称的目录，如/usr/share/check-mk-agent/plugins/60
Q：服务端过滤无用监控信息
A：
编辑/opt/omd/sites/monitor/etc/check_mk/main.mk，添加以下内容
ignored_checktypes = ["chrony", "kernel", "cpu.threads", "logwatch", "megaraid_pdisks", "ipmi", "ipmi_sensors", "mounts", "ps", "ps.perf", "postfix_mailq", "postfix_mailq_status", "logins", "omd_apache", "omd_status", "livestatus_status"]
Q：监控数据量大的时候，是如何做优化的
A：
单机用目录方式进行优化，另外多机的话，还支持分布式
Q：如何变更检测时间及重试次数
A：
Host & Service Parameters -> Monitoring Configuration -> Service Checks -> Normal check interval for service checks 设置1分钟
Host & Service Parameters -> Monitoring Configuration -> Service Checks -> Retry check interval for service checks 设置1分钟
Host & Service Parameters -> Monitoring Configuration -> Service Checks -> Maximum number of check attempts for service 设置1次
Host & Service Parameters -> Monitoring Configuration -> Service Checks -> Normal check interval for host checks 设置1分钟
Host & Service Parameters -> Monitoring Configuration -> Service Checks -> Retry check interval for host checks 设置1分钟
Host & Service Parameters -> Monitoring Configuration -> Service Checks -> Maximum number of check attempts for service 设置1次
Q：如何自动添加发现的新监控项
A：
Host & Service Parameters -> Monitoring Configuration -> Inventory and Check_MK settings -> Periodic service discovery 增加rule
Perform service discovery every 设置为1h
Severity of unmonitored services 设置为warning
Severity of vanished services 设置为ok
Automatically update service configuration中，mode设置为Add unmonitored services & remove varnished services
Group discovery and activation for up to 设置为10m
Q：支持批量主机导入吗
A：Host -> Bulk host import
Q：建立主机组并关联主机
A:
Host & Service Groups -> new host group
Host Tags -> new tag group
Host & Service Parameters -> Grouping -> Assignment of hosts to host groups
新建rule , Assignment of hosts to host groups 选择group_bj，Conditions下host tag选择 location is group_bj
Q：磁盘io模式由summary变更为separate
A：
Host & Service Parameters -> Parameters for discovered services -> Storage, Filesystems and Files -> Discovery mode for Disk IO check
新建rule，选择Create a separate check for each physical disk
Q：网络设备接口名称由id变更为description
A：
Host & Service Parameters -> Parameters for discovered services -> Discovery - automatic service detection -> Network Interface and Switch Port Discovery，新建rule，选择Use description as service name for network interface checks，选择use description
Q：改变监控阀值
A：

Host & Service Parameters -> Parameters for discovered services -> Operating System Resources -> CPU load (not utilization!)，添加rule，选择fixed level，warning & critical设置为10
#cpu
Host & Service Parameters -> Parameters for discovered services -> Operating System Resources -> CPU utilization on Linux/UNIX，添加rule，选择Alert on too high CPU utilization，warning & critical设置为95，选择Alert on too high disk wait (IO wait)，warning & critical设置为50

Filesystem larger than 300G -> Absolute free space -> warning & critical设置为10000MB
Filesystem larger than 100G -> Absolute free space -> warning & critical设置为5000MB
Filesystem larger than 10G -> Absolute free space -> warning & critical设置为1000MB
Filesystem larger than 1G -> Absolute free space -> warning & critical设置为100MB
Filesystem larger than 300M -> Absolute free space -> warning & critical设置为20MB
Filesystem larger than 100M -> Absolute free space -> warning & critical设置为10MB
Filesystem larger than 0B -> Absolute free space -> warning & critical设置为0MB
#traffic
Host & Service Parameters -> Parameters for discovered services -> Networking -> Network interfaces and switch ports，新建rule，
