Examples of URLs in Zabbix self-discovery monitoring app

Demand:

There are a number of URLs that need to be monitored, in the form of http://www.baidu.com, requiring a URL state of 200 to alert and get response time (URLs can be changed to URLs in their app).

Detailed Requirements Analysis:

A large number of URLs, and the URL changes frequently, now monitoring with Zabbix, if manually add a template, will cause a lot of duplication, if the use of script +mail, can not be graphically rendered

Solution:

Zabbix has discovery function to solve this problem easily

First, let's find a Zabbix client to implement the next function.

First we start from the beginning, let's install the Zabbix client

RPM-IVH http://repo.zabbix.com/zabbix/3.4/rhel/6/x86_64/zabbix-release-3.4-1.el6.noarch.rpm

Yum-y Install Zabbix-agent

Vim web_site_code_status.sh

The script content is:

#!/bin/bash

# function:monitor TCP Connect status from Zabbix

SOURCE/ETC/BASHRC >/dev/null 2>&1

Source/etc/profile >/dev/null 2>&1

#/usr/bin/curl-o/dev/null-s-W%{http_code} http://$1/

Web_site_discovery () {

Web_site= ($ (cat/etc/zabbix/web.txt|grep-v "^#"))

printf ' {\ n '

printf ' \ t ' data: [\ n '

For ((i=0;i<${#WEB_SITE [@]};++i))

{

Num=$ (Echo $ ((${#WEB_SITE [@]}-1))

If ["$i"! = ${num}];

Then

printf "\t\t{\ n"

printf "\t\t\t\" {#SITENAME}\ ": \" ${web_site[$i]}\ "},\n"

Else

printf "\t\t{\ n"

printf "\t\t\t\" {#SITENAME}\ ": \" ${web_site[$num]}\ "}]}\n"

Fi

}

}

Web_time_total () {

/usr/bin/curl-o/dev/null-s-W%{time_total} http://$1

}

Web_site_code () {

/usr/bin/curl-o/dev/null-s-W%{http_code} http://$1

}

Case "$" in

Web_site_discovery)

Web_site_discovery

;;

Web_time_total)

Web_time_total

;;

Web_site_code)

Web_site_code

;;

*)

echo "usage:$0 {Web_site_discovery|web_site_code [URL]}"

;;

Esac

/opt/scripts/web.txt Create the WEB.txt file in the script path, the file content is to monitor the URL, the format is as follows (add your own actual URL):

Http://www.baidu.com

http://www.sina.com.cn

Http://www.163.com 10.10.10.10

Http://www.sohu.com 115.23.16.97:80

Http://www.111.com

In the Zabbix Client plus config file:

Vim/etc/zabbix/zabbix_agentd.d/web_site_discovery.conf

Userparameter=web.site.discovery,/etc/zabbix/scripts/web_site_code_status.sh Web_site_discovery

Userparameter=web.site.code[*],/etc/zabbix/scripts/web_site_code_status.sh Web_site_code

Test is normal:

$ zabbix_get-s 10.0.0.109-k Web.site.discovery

{

"Data": [

{

"{#SITENAME}": "Www.baidu.com"},

{

"{#SITENAME}": "Www.sina.com.cn"},

{

"{#SITENAME}": "Www.****.com"},

{

' {#SITENAME} ': ' Www.****.com '}]}

$ zabbix_get-s 10.0.0.109-k web.site.code[www.163.com]

200

Adding on the Zabbix server Web

Click Add

Then go to create the discovery rule

The monitoring is complete!

Curl-o/dev/null-s-W '%{time_connect}:%{time_starttransfer}:%{time_total} ' http://www.miotour.com

Results: 0.244:1.044:2.672

Time Indicator Explanation:

Time_connect the time it took to establish a TCP connection to the server

Time_starttransfer the time it takes for the WEB server to return the first byte of data after making a request

Time_Total the time it took to complete the request

After the request is made, the time it takes for the WEB server to process the request and start sending the data back is

(Time_starttransfer)-(time_connect) 0.244 = 0.8 seconds
