ZABBIX agent adds a user-defined monitoring item -- Ping to destination IP link monitoring

cause ：

        A friend's need ： headquarters and Branch Inter site data walk SDWAN, But sometimes there is a link failure , The route is not switched in time , It will cause users to disconnect . So I want to pass Zabbix monitor headquarters To Link state of the branch and Alarms are easy to handle in time .

        You want the monitored end to execute a Zabbix There is no predefined detection , Need to use Zabbix The user-defined parameter function of provides this method . We can configure the file on the client side zabbix_angentd.conf It's equipped with UserParameter .

Configuration method ：

        Windows Next zabbix_agentd.conf To configure ：

#  Log file address 
LogFile=D:\zabbix_agentd.log


#  If set to pure passive mode , It can be commented out , It doesn't matter if you don't comment , Write zabbix server  Of IP Or domain name 
Server=1199.1858.2372.1155


#  Active mode  zabbix server  Of IP Or domain name 
ServerActive=1199.1858.2372.1155


#  The use of host names is not configured , Need and  zabbix server  The hostname in is the same 
Hostname=Nuzis-Host


#  client agent Pattern ： Set to 0 Indicates active mode is enabled ,  Don't listen on the local port 
StartAgents=0


#  Allow unsafe characters 
#UnsafeUserParameters=1


#  interval 60s Refresh the active monitoring configuration information time , Default 120s
RefreshActiveChecks=60

#  Whether to run zabbix server Execute remote commands on this server ,0 - disabled;1 - enabled
EnableRemoteCommands=1


#  Record the execution of the prototype shell Command log , The level of warrning;0 - disabled;1 - enabled
LogRemoteCommands=1


#  Customized monitoring items 
UserParameter=testping,echo "This is Test Ping!!!!"

         Linux Next zabbix_agentd.conf To configure ：

[[email protected] zabbix]# vim zabbix_agentd.conf

# PID  Process documents 
PidFile=/var/run/zabbix/zabbix_agentd.pid


# Log Log files 
LogFile=/var/log/zabbix/zabbix_agentd.log


#  Active mode  zabbix server  Of IP Or domain name 
ServerActive=1199.1858.2372.1155


#  The use of host names is not configured , Need and  zabbix server  The hostname in is the same 
Hostname=Nuzis-Host


Hostname=centos777-111199


#  client agent Pattern ： Set to 0 Indicates active mode is enabled ,  Don't listen on the local port 
StartAgents=0


#  Whether to run zabbix server Execute remote commands on this server ,0 - disabled;1 - enabled
EnableRemoteCommands=1


#  Record the execution of the prototype shell Command log , The level of warrning;0 - disabled;1 - enabled
LogRemoteCommands=1


# Centos7  By default root user , If it is zabbix Users do not need this sentence 
AllowRoot=1


#  Allow unsafe characters 
#UnsafeUserParameters=1


#  interval 60s Refresh the active monitoring configuration information time , Default 120s
RefreshActiveChecks=60


# Custom configuration files , Different configurations are written to different files , then include.
Include=/etc/zabbix/zabbix_agentd.d/*.conf


#  Customized monitoring items 
UserParameter=ifNumber,/etc/init.d/network status |awk 'NR==4'|awk -v RS="@#$j" '{print gsub(/ /,"&")+1}'

Zabbix Server To configure ：

        1- Add host

         2- Add monitor

         3- confirm zabbix-agent Running normally

        4- Monitor the panel to view the latest data

         5- Because the data is Zabbix-agent interval 60s（ Default 120s） Active push to Zabbix Server Of , So if the monitoring item status is Unavailable 、Unsupported item key etc. , You can do it manually Disable and enable .

         6- After that, you should be able to obtain data normally

ping Link monitoring will be written another day
