一、告警系统主脚本
main.sh内容:
#!/bin/bash
#Written by amo.
# 是否发送邮件的开关:
export send=1
# 过滤ip地址:
/sbin/ifconfig |grep -A1 "eno16777736: "|awk '/inet/ {print $2}'
dir=`pwd`
# 只需要最后一级目录名:
last_dir=`echo $dir|awk -F'/' '{print $NF}'`
# 下面的判断目的是,保证执行脚本的时候,我们在bin目录里,不然监控脚本、邮件和日志很有可能找不到:
if [ $last_dir == "bin" ] || [ $last_dir == "bin/" ]; then
conf_file="../conf/mon.conf"
else
echo "you shoud cd bin dir"
exit
fi
exec 1>>../log/mon.log 2>>../log/err.log
echo "`date +"%F %T"` load average"
/bin/bash ../shares/load.sh
#先检查配置文件中是否需要监控502:
if grep -q 'to_mon_502=1' $conf_file; then
export log=`grep 'logfile=' $conf_file |awk -F '=' '{print $2}' |sed 's/ //g'`
/bin/bash ../shares/502.sh
fi
20.21 告警系统配置文件
告警系统配置文件
进入conf目录:
mon.conf内容:
## to config the options if to monitor
## 定义mysql的服务器地址、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则监控,为0不监控
to_mon_httpd=0
## php 如果是1则监控,为0不监控
to_mon_php_socket=0
## http_code_502 需要定义访问日志的路径
to_mon_502=1
logfile=/data/log/xxx.xxx.com/access.log
## request_count 定义日志路径以及域名
to_mon_request_count=0
req_log=/data/log/www.discuz.net/access.log
domainname=www.discuz.net
20.22 告警系统监控项目
告警系统监控项目
进入shares目录:
1、 load.sh内容:
#! /bin/bash
##Writen by amo##
load=`uptime |awk -F 'average:' '{print $2}'|cut -d',' -f1|sed 's/ //g' |cut -d. -f1`
if [ $load -gt 10 ] && [ $send -eq "1" ]
then
echo "$addr `date +%T` load is $load" >../log/load.tmp
/bin/bash ../mail/mail.sh $addr "$addr\_load:$load" `cat ../log/load.tmp`
fi
echo "`date +%T` load is $load"
2、502.sh内容:
#! /bin/bash
d=`date -d "-1 min" +%H:%M`
c_502=`grep :$d: $log |grep ' 502 '|wc -l`
if [ $c_502 -gt 10 ] && [ $send == 1 ]; then
echo "$addr $d 502 count is $c_502">../log/502.tmp
/bin/bash ../mail/mail.sh $addr\_502 $c_502 ../log/502.tmp
fi
echo "`date +%T` 502 $c_502"
3、监控磁盘使用率:
disk.sh内容
#! /bin/bash
##Writen by amo##
rm -f ../log/disk.tmp
for r in `df -h |awk -F '[ %]+' '{print $5}'|grep -v Use`
do
if [ $r -gt 90 ] && [ $send -eq "1" ]
then
echo "$addr `date +%T` disk useage is $r" >>../log/disk.tmp
fi
if [ -f ../log/disk.tmp ]
then
df -h >> ../log/disk.tmp
/bin/bash ../mail/mail.sh $addr\_disk $r ../log/disk.tmp
echo "`date +%T` disk useage is nook"
else
echo "`date +%T` disk useage is ok"
fi
