一 Zabbix监控Mysql
监控Mysql,Zabbix提供了一个监控模板,所有可以直接使用.或者使用Percona提供的监控模板.
1. 使用自带监控模板
1.1.1 编写监控模板
#!/bin/bash # 主机地址IP MYSQL_HOST='127.0.0.1' # 端口 MYSQL_PORT='3306' # 数据连接 MYSQL_CONN="/usr/bin/mysqladmin -h${MYSQL_HOST} -P${MYSQL_PORT}" # 检查参数是否正确 if [ $# -ne "1" ];then echo "arg Error!" fi # 获取数据 case $1 in Uptime) result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"` echo $result ;; Com_update) result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3` echo $result ;; Slow_queries) result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"` echo $result ;; Com_select) result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3` echo $result ;; Com_rollback) result=`${MYSQL_CONN} extended-status |grep -w "Com_rollback"|cut -d"|" -f3` echo $result ;; Questions) result=`${MYSQL_CONN} status|cut -f4 -d":"|cut -f1 -d"S"` echo $result ;; Com_insert) result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3` echo $result ;; Com_delete) result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3` echo $result ;; Com_commit) result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3` echo $result ;; Bytes_sent) result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3` echo $result ;; Bytes_received) result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3` echo $result ;; Com_begin) result=`${MYSQL_CONN} extended-status |grep -w "Com_begin"|cut -d"|" -f3` echo $result ;; *) echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|C om_begin)" ;; esac
1.1.2 异常处理
如果mysql5.7以上版本执行脚本出现Waring信息,解决如下:
[mnysqladmin] user=root password=xxxxx
1.1.3 添加权限以及定义监控项
# 添加权限属主信息 chmod 755 check_mysql.sh chown zabbix.zabbix check_mysql.sh chmod +x check_mysql.sh # /etc/zabbix/zabbix_agentd.d 下创建 UserParameter_mysql.conf文件,内容如下: UserParameter=mysql.status[*],/etc/zabbix/zabbix_agentd.d/check_mysql.sh $1 UserParameter=mysql.ping,HOME=/etc /usr/local/mysql/bin/mysqladmin ping 2>/dev/null| grep -c alive UserParameter=mysql.version,/usr/local/mysql/bin/mysql -V
1.1.4 Mysql监控主机添加模板
二 监控Nginx
2.1.1 开启Nginx状态页
location /nginx-status { stub_status on; access_log off; allow 127.0.0.1; deny all; } # 这段location是打开nginx的状态监控页面, “stub_status”为“on”表示开启状态监控模块, “access_log off”表示关闭这个页面的访问日志, 接下来的“allow”表示这个状态监控页面允许哪些客户端访问,一般允许本机(127.0.0.1)除了允许访问的客户端外,其它都通过“deny all”禁止访问即可。
2.1.2 检查 & 参数说明
# curl http://127.0.0.1/nginx-status Active connections: 3 server accepts handled requests 1649812 1649812 2770589 Reading: 0 Writing: 1 Waiting: 2 # 参数说明 Active connections: 对后端发起的活动连接数; accepts:nginx总共处理了多少个连接; handled:nginx成功创建了几次握手; requests:nginx总共处理了多少请求。 Reading:nginx读取客户端的header数; Writing: nginx 返回给客户端的header数; Waiting: nginx 请求处理完成,正在等待下一请求指令的连接.
2.1.3 编写Nginx监控脚本
# cat nginx_status.sh #!/bin/bash # Set Variables HOST=127.0.0.1 PORT="80" if [ $# -eq "0" ];then echo "Usage:$0(active|reading|writing|waiting|accepts|handled|requests|ping)" fi # Functions to return nginx stats function active { /usr/bin/curl "http://$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}' } function ping { /sbin/pidof nginx | wc -l } # Run the requested function $1
添加执行权限,以及编写UserParameter
chmod 755 nginx_status.sh chmod +x nginx_status.sh chown zabbix. nginx_status.sh # 在/etc/zabbix/zabbix_agentd.d 创建UserParameter_nginx.conf 内容如下: UserParameter=nginx.status[*],/etc/zabbix/shell/nginx_status.sh $1
2.1.4 创建模板以及链接主机
