zabbix自动发现linux系统挂载的nas盘,并实现读写故障的监控告警

一.准备好被监控机器上面执行脚本,以备服务端发现和监控

脚本的内容:

ZABBI安装路径可执行文件及配置文件根据实际部署的路径更改

#!/bin/bash
>/zabbixconfpath/zbx_nas.conf >/zabbixscriptspath/findnas.sh >/zabbixscriptspath/checknas.sh >/zabbixscriptspath/checknaswrite.sh
(
cat <<EOF
UserParameter=nas.discovery,/zabbixscriptspath/findnas.sh
UserParameter=nas.check[*],/zabbixscriptspath/checknas.sh \$1
UserParameter=nas.checkwrite[*],/zabbixscriptspath/checknaswrite.sh \$1
EOF
)>>/zabbixscriptspath/zbx_nas.conf
 
(
cat <<EOF
#!/bin/bash
mount_discovery () { 
mount | grep "type nfs" | grep -v "nfsd" | awk '{print \$3}' > /zabbixscriptspath/naslists.txt
chown zabbixuser:zabbixuser /zabbixscriptspath/naslists.txt
NAS_LIST=(\$(cat  /zabbixscriptspath/naslists.txt)) 
        printf '{\n' 
        printf '\t"data":[\n' 
for((i=0;i<\${#NAS_LIST[@]};++i)) 
{ 
num=\$(echo \$((\${#NAS_LIST[@]}-1))) 
        if [ "\$i" != \${num} ]; 
                then 
        printf "\t\t{ \n" 
        printf "\t\t\t\"{#NASNAME}\":\"\${NAS_LIST[\$i]}\"},\n" 
                else 
                        printf  "\t\t{ \n" 
                        printf  "\t\t\t\"{#NASNAME}\":\"\${NAS_LIST[\$num]}\"}]}\n" 
        fi 
} 
} 
mount_discovery
EOF
)>>/zabbixscriptspath/findnas.sh
 
(
cat <<EOF
#!/bin/bash
timeout 3 df -h \$1 > /dev/null
if [ \$? -ne 0 ]; then
    echo 1
else
    echo 0
fi
EOF
)>>/zabbixscriptspath/checknas.sh
 
(
cat <<EOF
#!/bin/bash
timeout 3 touch \$1/zabbixtestfiles.txt.txt.txt > /dev/null
if [ \$? -ne 0 ]; then
    echo 1
else
    echo 0
fi
EOF
)>>/zabbixscriptspath/checknaswrite.sh
 
chmod a+x /zabbixscriptspath/findnas.sh /zabbixscriptspath/checknas.sh /zabbixscriptspath/checknaswrite.sh
systemctl restart zabbix-agent.service || ps -ef | grep zabbix-agent | grep -v grep | awk '{print $2}' | xargs -I {} kill {};sleep 1;su - zabbixuser -c "/zabbixpath/sbin/zabbix_agentd -c /zabbixpath/conf/zabbix_agentd.conf"

二.ZABBIX监控模板导出的XML文件如下:

                    <item_prototypes>
                        <item_prototype>

                            <name>chknas write on {#NASNAME}name>
                            <key>nas.checkwrite[{#NASNAME}]key>
                            <delay>60mdelay>
                            <trigger_prototypes>
                                <trigger_prototype>

三.导入模板,在被监控的主机上执行脚本和应用监控模板,实现对被监控主机NAS盘读写情况的监控

并根据实际的需求启用/禁用触发器
