用于Nagios中监控服务器连接数脚本
最近因为服务器不断有增加新的业务，需要对服务器的最大连接数进行调整评估，所以就利用Nagios去监控相应的连接数，脚本也是利用Nagios发送相应的转态来实现监控，实现也很简单#/bin/bash
#Used to monitor the number of socket connections in Nagios

STATE_OK=0
STATE_WARNING=1
STATE_CRITICALLL=2
STATE_UNKNOWN=3
declare -i socket_num=$(ss -an|wc -l)
declare -i max_num=65535
if [ $socket_num -le $max_num ] ; then
echo "The number of socket connections is $socket_num.OK"
exit $STATE_OK
else
echo "error!!!The number of socket connections is too much.the number is $socket_num"
exit $STATE_CRITICALL
fi
