按照zabbix客户端及自定义监控nginx连接状态

ouiytre

一、下载客户端按照包，这里用rpm包安装

1	[iyunv@localhost ~]# rpm -ivh http://repo.zabbix.com/zabbix/3. ... .4-1.el7.x86_64.rpm

修改客户端配置文件

1 2	Server=127.0.0.1 ServerActive=127.0.0.1

改为zabbix server实际的IP地址(比如zabbix server的IP地址为10.0.0.100)

1 2	Server=10.0.0.100 ServerActive=10.0.0.100

重启zabbix 客户端

1	[iyunv@zabbix]# systemctl restart zabbix-agent

二、自定义脚本监控nginx连接状态:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

#!/bin/bash HOST=localhost PORT="9999" function active {         /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Active' | awk '{print $NF}'         } function reading {         /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Reading' | awk '{print $2}'        } function writing {         /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Writing' | awk '{print $4}'        } function waiting {         /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| grep 'Waiting' | awk '{print $6}'        } function accepts {         /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print $1}'        } function handled {         /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print $2}'        } function requests {         /usr/bin/curl "http://$HOST:$PORT/nginx-status/" 2>/dev/null| awk NR==3 | awk '{print $3}'        } $1

将脚本存放与脚本目录，注意该目录根据自己情况定义，我这里用rpm 按照zabbix-agent客户端，所以直接放在/etc/zabbix/script目录下

1 2 3

[iyunv@localhost script]# ll nginx-status.sh -rwx------ 1 root root 947 Mar 22 10:49 nginx-status.sh [iyunv@localhost script]#

不要忘了给脚本执行权限

1 2 3 4 5

[iyunv@localhost script]# chmod +x nginx-status.sh [iyunv@localhost script]# [iyunv@localhost script]# ll nginx-status.sh -rwxr-xr-x 1 root root 947 Mar 22 10:49 nginx-status.sh [iyunv@localhost script]#

修改配置文件,在末尾添加如下内容：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27

[iyunv@localhost zabbix]# vim zabbix_agentd.conf ...................................省略部分...................................................... ### DISK I/O UserParameter=custom.vfs.dev.read.ops ,cat /proc/diskstats | grep $1 | head -1 | awk '{print $$4}'   UserParameter=custom.vfs.dev.read.ms ,cat /proc/diskstats | grep $1 | head -1 | awk '{print $$7}'   UserParameter=custom.vfs.dev.write.ops ,cat /proc/diskstats | grep $1 | head -1 | awk '{print $$8}'   UserParameter=custom.vfs.dev.write.ms ,cat /proc/diskstats | grep $1 | head -1 | awk '{print $$11}'   UserParameter=custom.vfs.dev.io.active ,cat /proc/diskstats | grep $1 | head -1 | awk '{print $$12}'   UserParameter=custom.vfs.dev.io.ms ,cat /proc/diskstats | grep $1 | head -1 | awk '{print $$13}'   UserParameter=custom.vfs.dev.read.sectors ,cat /proc/diskstats | grep $1 | head -1 | awk '{print $$6}'   UserParameter=custom.vfs.dev.write.sectors ,cat /proc/diskstats | grep $1 | head -1 | awk '{print $$10}' ######## TCP connections total UnsafeUserParameters=1 UserParameter=synrecv,/etc/zabbix/script/tcp_connection_status.sh SYNRECV UserParameter=estab,/etc/zabbix/script/tcp_connection_status.sh ESTAB UserParameter=timewait,/etc/zabbix/script/tcp_connection_status.sh TIMEWAIT UserParameter=last_ack,/etc/zabbix/script/tcp_connection_status.sh LAST_ACK UserParameter=total,/etc/zabbix/script/tcp_connection_status.sh TOTAL #####Nginx Status UserParameter=nginx.accepts,/etc/zabbix/script/nginx-status.sh accepts UserParameter=nginx.handled,/etc/zabbix/script/nginx-status.sh handled UserParameter=nginx.requests,/etc/zabbix/script/nginx-status.sh requests UserParameter=nginx.connections.active,/etc/zabbix/script/nginx-status.sh active UserParameter=nginx.connections.reading,/etc/zabbix/script/nginx-status.sh reading UserParameter=nginx.connections.writing,/etc/zabbix/script/nginx-status.sh writing UserParameter=nginx.connections.waiting,/etc/zabbix/script/nginx-status.sh waiting EnableRemoteCommands=1

然后重启zabbix客户端

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

[iyunv@zabbix]# systemctl restart zabbix-agent [iyunv@localhost zabbix]# systemctl status zabbix-agent ● zabbix-agent.service - Zabbix Agent    Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; disabled; vendor preset: disabled)    Active: active (running) since Wed 2017-03-22 11:03:05 CST; 6min ago   Process: 13613 ExecStop=/bin/kill -SIGTERM $MAINPID (code=exited, status=0/SUCCESS)   Process: 13615 ExecStart=/usr/sbin/zabbix_agentd -c $CONFFILE (code=exited, status=0/SUCCESS) Main PID: 13617 (zabbix_agentd)    CGroup: /system.slice/zabbix-agent.service            ├─13617 /usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf            ├─13618 /usr/sbin/zabbix_agentd: collector [idle 1 sec]            ├─13619 /usr/sbin/zabbix_agentd: listener #1 [waiting for connection]            ├─13620 /usr/sbin/zabbix_agentd: listener #2 [waiting for connection]            └─13621 /usr/sbin/zabbix_agentd: listener #3 [waiting for connection] Mar 22 11:03:05 localhost systemd[1]: Starting Zabbix Agent...

最后在服务端添加主机对应的监控项，键值为如下字段：

1 2 3 4 5 6 7

nginx.accepts nginx.handled nginx.requests nginx.connections.active, nginx.connections.reading nginx.connections.writing nginx.connections.waiting
