19.12 Adding custom monitoring items

Requirements: Monitor the number of 80-port connections for a web and figure out

Two steps:
1) Zabbix Monitoring Center to create a monitoring project; 2) graphic representation of the monitoring project

For the first step, you need to define the script to the client
vim/usr/local/sbin/estab.sh//content is as follows
#!/bin/bash
# #获取80端口并发连接数
Netstat-ant |grep ': |grep-c established

chmod 755/usr/local/sbin/estab.sh

Edit config file on client vim/etc/zabbix/zabbix_agentd.conf//Add
Unsafeuserparameters=1//means using a custom script
userparameter=my.estab.count[],/usr/local/sbin/estab.sh
The key of the custom monitoring item is My.estab.count, the following [] script parameters are written, if no parameters can be omitted, the script is/usr/local/sbin/estab.sh
Restart Zabbix-agent Service Systemctl restart Zabbix-agent

First to the server authentication, execute the command
Zabbix_get-s 192.168.106.165-p 10050-k ' My.estab.count '
Then add monitoring items in the Zabbix Monitoring Center (browser) configuration
Key-Value Write My.estab.count
After adding the item, go to "monitoring" and "latest data" to see if the item you just added has data appearing
With the data, you can add graphics.
"Configure"-"hosts"--"graphics"--"Create graphics"

19.13-14 Configuring Message Alarms

Use 163 or QQ mailbox to send alert mail
First log in to your 163 mailbox, set the POP3, IMAP, SMTP service to open
Open and record Authorization code
Then set the email alert to the monitoring center.
"Manage", "Alarm media type", "Create Media type"
{ALERT. SENDTO}, {ALERT. Subject},{alert. MESSAGE}

Create an alarm script mail.py
vim/usr/lib/zabbix/alertscripts/mail.py//Content Reference Https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master /d22z/mail.py
chmod 755/usr/lib/zabbix/alertscripts/mail.py
Create a user that accepts alerts, "manage", "user", "Create User", "Alarm vector", type select "Baojing", note the user's permissions, if there is no need to set permissions to the user group
Set the action, "config", "action", "Create action", name write "SendMail" (Custom), "action" page, the content is as follows
Host:{host.name} {HOST. IP}
Time:{event. DATE} {EVENT. TIME}
Level:{trigger. SEVERITY}
Name:{trigger.name}
Messages:{item.name}:{item. VALUE}
Id:{event.id}
"New Trigger condition", a maintenance state not in maintenance, B trigger warning degree >= not classified

"Action", select the sending user as the user just created, send only to select "Baojing"
Switch to "restore operation" and change the information to the following
Host:{host.name} {HOST. IP}
Time:{event. DATE} {EVENT. TIME}
Level:{trigger. SEVERITY}
Name:{trigger.name}
Messages:{item.name}:{item. VALUE}
Id:{event.id}
Click "New", "Action", select the sending user for the user just created, send only to select "Baojing"
Test alarms
