8-zabbix_sender说明和安装

zabbix_sender是一个命令行工具，可以用来发送Zabbix服务器处理性能数据。该工具通常用于长时间运行的用户脚本，用于定期发送可用性和性能数据。

zabbix Server获取key值有超时时间，如果自定义的key脚本需要执行很长时间，这将没法去做监控，而使用zabbix监控类型zabbix trapper，再配合zabbix_sender就可以给Zabbix Server传递监控数据另外如果不是Zabbix agent的主机,也可以通过 zabbix_sender工具和 crontab 实现监控和数据采集

范例: 安装 zabbix_sender

[root@ubuntu1804 ~]#apt -y install zabbix-sender
[root@centos8 ~]#yum -y install zabbix-sender
[root@ubuntu1804 ~]#zabbix_sender -V

范例: 查看 zabbix_sender 使用

[root@ubuntu1804 ~]#zabbix_sender -h
 zabbix_sender [-v] -z server [-p port] [-I IP-address] -s host -k key -o value
-c --config < file >                 #配置文件绝对路径
-z --zabbix-server <server>          #zabbix server的IP地址
-p --port <server port>              #zabbix server端口.默认10051
-s --host < hostname >               #主机名，zabbix agent里面配置的主机名（不是服务器
的 hostname ），不能使用ip地址
-I -- source -address <IP address>   #源IP
-k --key <key>                       #监控项的key
-o --value <key value>               #key值
-i --input- file <input file >     #从文件里面读取 hostname 、key、value,其中一行为
一条数据，使用空格作为分隔符，如果主机名带空格，那么请使用双引号包起来
-T --with-timestamps              #一行一条数据，空格作为分隔符: < hostname > <key> 
<timestamp> <value>，配合 --input- file option，timestamp为unix时间戳
-r --real-time                       #将数据实时提交给服务器
-v  --verbose                         #详细模式, -vv 更详细
#示例
zabbix_sender -z 127.0.0.1 -s "appserver" -k db.connections -o 100

案例 使用zabbix_sender发送信息

在非zabbix agent的客户端执行命令

[root@ubuntu1804 ~]#apt -y install zabbix-sender
[root@ubuntu1804 ~]#cat traper.txt
"Zabbix server" trapper_test "how are you?"
"Zabbix server" trapper_test "I am fine"
"Zabbix server" trapper_test "thank you"
"Zabbix server" trapper_test "how are you?"
#批量提交
[root@ubuntu1804 ~]#zabbix_sender -z 10.0.0.100 -i traper.txt 
Response from "10.0.0.100:10051": "processed: 4; failed: 0; total: 4; seconds 
spent: 0.000175"
sent: 4; skipped: 0; total: 4 #单个提交
[root@ubuntu1804 ~]#zabbix_sender -z 10.0.0.100 -s "Zabbix server" -k 
trapper_test -o "I am wangxiaochun"
Response from "10.0.0.100:10051": "processed: 1; failed: 0; total: 1; seconds 
spent: 0.000089"
sent: 1; skipped: 0; total: 1

案例配置非 Zabbix agent 实现内存监控

在被监控主机创建采集监控项数据的脚本

[root@ubuntu1804 ~]#cat memory_monitor.sh
#!/bin/bash
hostname=$1
zabbix_server_ip=10.0.0.100
TotalMemory() {
     TotalMemory=`cat /proc/meminfo | awk '/^MemTotal:/{print $2}' `
     echo -e "\"$hostname\" monitor[TotalMemory] $TotalMemory" >> 
/tmp/memory_monitor.txt
}
FreeMemory() {
     FreeMemory=`cat /proc/meminfo | awk '/^MemFree:/{print $2}' `
     echo  "\"$hostname\" monitor[FreeMemory] $FreeMemory" >> 
/tmp/memory_monitor.txt
}
TotalMemory
FreeMemory
zabbix_sender -z $zabbix_server_ip -i /tmp/memory_monitor.txt &> /dev/null
if [ $? -eq  0 ]; then
     echo 0
else
     echo 1
fi
rm  -f /tmp/memory_monitor.txt

创建计划任务

[root@ubuntu1804 ~]#crontab -e
* * * * * /root/memory_monitor.sh "Zabbix server"
