2.zabbix创建模板

监控项

vfs.file.regmatch[/tmp/tablespace.log,NO]

触发器

last(/Check the Oracle tablespace/vfs.file.regmatch[/tmp/tablespace.log,NO])=1

1.查找文件中的字符串，如果有则返回1，没有则返回0。
2.是否存在与字符串"NO"匹配的内容，如果匹配结果为1，则触发报警

3.定时任务

su - oraclecrontab -e# Check the Oracle tablespace
0 */3 * * * /home/oracle/scripts/oracle_cron.sh > /tmp/oracle_cron.sh.log 2>&1
