With regards to the uptime discrepancy, I can’t explain that. Perhaps @AlanM could weigh in on this?
The name of operating system would be pulling details from applicable /etc/*-release file on the endpoint. So for example, on one of my development BESRelays reports:
[username@servername ~]# cat /etc/centos-release
CentOS Linux release 7.7.**** (Core)
This is consistent with what’s reported by the BESClient for the endpoint.
Hope this helps.
Best,
