"network Error Check: In Or Out Errors"

Hello,

 

Could someone point me to where the script used for monitoring the “Network Error Check: IN or Out Errors” is located in Uptime 7.1?

    For some reason, Uptime keeps reporting an “In or out errors >=5 for -(15.0)” where clearly there are no indication of any I/O error on any of the network interface on my server or network devices. Also, is there anyway I can look deeper into this? Thanks.
