main.sh內容

是否發送郵件的開關
export send=1
過濾ip地址
export addr=/sbin/ifconfig |grep -A1 "ens33: "|awk ‘/inet/ {print $2}‘
dir=pwd
只需要最後一級目錄名
last_dir=echo $dir|awk -F‘/‘ ‘{print $NF}‘
下面的判斷目的是，保證執行腳本的時候，我們在bin目錄裏，不然監控腳本、郵件和日誌很有可能找不到
if [ $last_dir == "bin" ] || [ $last_dir == "bin/" ]; then
else
echo "you shoud cd bin dir"
exit

#先檢查配置文件中是否需要監控502

20.21 告警系統配置文件
mon.conf內容
to config the options if to monitor
定義mysql的服務器地址、端口以及user、password
to_mon_cdb=0? ?##0 or 1, default 0,0 not monitor, 1 monitor
db_ip=10.20.3.13
db_port=3315
db_user=username
db_pass=passwd
httpd? ?如果是1則監控，為0不監控
to_mon_httpd=0
php 如果是1則監控，為0不監控
to_mon_php_socket=0
http_code_502??需要定義訪問日誌的路徑
to_mon_502=1
logfile=/data/log/xxx.xxx.com/access.log
request_count? ?定義日誌路徑以及域名
to_mon_request_count=0
req_log=/data/log/www.discuz.net/access.log
