一 Zabbix監控Mysql

    監控Mysql,Zabbix提供了一個監控模板,全部能夠直接使用.或者使用Percona提供的監控模板.mysql

1. 使用自帶監控模板

1.1.1 編寫監控模板

#!/bin/bash

# 主機地址IP
MYSQL_HOST='127.0.0.1'

# 端口
MYSQL_PORT='3306'

# 數據鏈接
MYSQL_CONN="/usr/bin/mysqladmin -h${MYSQL_HOST} -P${MYSQL_PORT}"

# 檢查參數是否正確
if [ $# -ne "1" ];then
    echo "arg Error!"
fi

# 獲取數據
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 異常處理

　　若是mysql5.7以上版本執行腳本出現Waring信息,解決以下:nginx

[mnysqladmin]
user=root
password=xxxxx

1.1.3 添加權限以及定義監控項

# 添加權限屬主信息
chmod 755 check_mysql.sh
chown zabbix.zabbix check_mysql.sh
chmod +x check_mysql.sh

# /etc/zabbix/zabbix_agentd.d 下建立 UserParameter_mysql.conf文件,內容以下:
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監控主機添加模板sql

   

二 監控Nginx

2.1.1 開啓Nginx狀態頁

location /nginx-status {
  stub_status on;
  access_log  off;
  allow 127.0.0.1;
  deny all;      
}

# 這段location是打開nginx的狀態監控頁面，
「stub_status」爲「on」表示開啓狀態監控模塊，
「access_log  off」表示關閉這個頁面的訪問日誌，
接下來的「allow」表示這個狀態監控頁面容許哪些客戶端訪問，通常容許本機（127.0.0.1）除了容許訪問的客戶端外，其它都經過「deny all」禁止訪問便可。

2.1.2 檢查 & 參數說明

# curl http://127.0.0.1/nginx-status
Active connections: 3 
server accepts handled requests
 1649812 1649812 2770589 
Reading: 0 Writing: 1 Waiting: 2 

# 參數說明
Active connections: 對後端發起的活動鏈接數；
accepts：nginx總共處理了多少個鏈接；
handled：nginx成功建立了幾回握手；
requests：nginx總共處理了多少請求。
Reading：nginx讀取客戶端的header數；
Writing: nginx 返回給客戶端的header數；
Waiting: nginx 請求處理完成，正在等待下一請求指令的鏈接.

2.1.3 編寫Nginx監控腳本

# 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

　　添加執行權限,以及編寫UserParametershell

chmod 755 nginx_status.sh 
chmod +x nginx_status.sh 
chown zabbix. nginx_status.sh 

# 在/etc/zabbix/zabbix_agentd.d 建立UserParameter_nginx.conf 內容以下:
UserParameter=nginx.status[*],/etc/zabbix/shell/nginx_status.sh  $1

2.1.4 建立模板以及連接主機
