Automatic discovery of zabbix automatic monitoring
1. Introduction to Auto Discovery
It is very convenient to use automatic discovery when we have thousands of hosts that need to be monitored. We only need to create an automatic discovery rule and set the scope of automatic discovery. According to the set action, the Linux server with the agent can be installed. Automatically added to monitoring
Note: The automatically discovered host must have zabbix-agent installed in advance, so the automatic discovery action is based on the output of the system.uname monitoring item as a judgment, and the system.uname monitoring item is to check whether zabbix-agent is installed
Installing zabbix-agent will output:
[root@zabbix-server ~]# zabbix_get -s 192.168.81.220 -k system.uname
Linux 192_168_81_220 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64
If zabbix-agent is not installed, it will output:
[root@zabbix-server ~]# zabbix_get -s 192.168.81.250 -k system.uname
zabbix_get [28088]: Get value error: cannot connect to [[192.168.81.250]:10050]: [113] No route to host
The basic operation is
1. Install zabbix-agent and configure
2. Create automatic discovery rules
3. Set the automatic discovery action
2. Install zabbix-agent on the controlled host
[root@192 ~]# yum localinstall zabbix-agent-4.0.24-1.el7.x86_64.rpm -y
[root@192 ~]# vim /etc/zabbix/zabbix_agentd.conf
Server=192.168.81.210
[root@192 ~]# systemctl start zabbix-agent
3. Configure zabbix automatic discovery
3.1. Create automatic discovery rules
Configuration-automatic discovery-create automatic discovery-fill in the information-add
Name: 192.168.81.0
Automatically discovered by agent agent: no agent agent
ip range: 192.168.81.1-254
Add a new check:
Check type: zabbix client
Port range: 10050
Key value: system.uname
Device uniqueness rule: ip address
3.2. Create action
Used to automatically discover the host and add it to zabbix
Configuration-Action-Event source selection automatic discovery
Click on an existing action
The "received value contains Linux " here is the value obtained by the monitoring item system.uname for filtering
Click to enter and then click to add operation instructions, there is no need to change the action
Finally click to enable
4. Speed up zabbixserver
[root@zabbix-server ~]# systemctl restart zabbix-server
5. Check whether the host has been discovered by automatic discovery
Click to monitor-automatic discovery
You can see that the host has been monitored
Just wait for the host to turn green
6. Automatic discovery is successful
You can see that when the host is automatically discovered, it will add hosts and link templates according to the actions we configured
