Zabbix monitors whether rsync can pull logs normally through shell script

Background: The
    company synchronizes overseas server logs to local analysis through rsync scripts. Due to network quality problems, it often fails to be pulled. In order to be processed in time, it is necessary to monitor whether the logs can be pulled and processed normally
    . Trigger alarm when the log size within hours is less than 5M or 10M

# statistical size of the combined log within five hours, If both are less than 5M, an alarm is triggered: it may be that no logs have been pulled, or the problem may be merged 
# Get hours 0 ~ 24
