一、監控系統負載

[[email protected] ~]# vim mon/shares/load.sh
#!/bin/bash
load=`uptime |awk -F ‘average:‘ ‘{print $2}‘|cut -d‘,‘ -f1|sed ‘s/ //g‘ |cut -d. -f1`
if [ $load -gt 20 ] && [ $send -eq "1" ]
then
    echo "$addr `date +%T` load is $load" >../log/load.tmp
    /bin/bash ../mail/mail.sh $addr\_load $load ../log/load.tmp
fi
echo 
 
"`date +%T` load is $load"

二、監控 502

[[email protected] ~]# vim mon/shares/502.sh
#!/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"

三、監控磁盤

[[email protected] ~]# vim mon/shares/disk.sh
#! /bin/bash
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
