监控磁盘io发现脚本
脚本内容：

#!/usr/bin/perl

# Notice
# Apply zabbix version 2.4.x to 3.0.3
# auto search disk i/o

tcp监控：

计划任务中添加：

*/1 * * * * /usr/sbin/ss  -tan|awk 'NR>1{++S[$1]}END{for (a in S) print a,S[a]}' > /tmp/tcp-status.txt
*/1 * * * * /usr/sbin/ss -o state established '( dport = :http or sport = :http )' |grep -v Netid > /tmp/httpNUB.txt
UserParameter：

UserParameter=tcp.status[*],awk '{if ($$1~/^$1/)print $$2}' /tmp/tcp-status.txt
UserParameter=tcp.httpd_established,awk 'NR>1' /tmp/httpNUB.txt|wc -l
