We have Linux monitoring, metrics collected by Prometheus and Zabbix agents. Some people in the community are asking about monitoring Windows OS, which is not very popular in service backend deployment, but still have some.
If someone new to SkyWalking or anything, want to take a reference from existing Linux monitoring and add this feature. We are welcome to accept.

Describe the bug
When joining to tables on the same column name SQL error happens

To Reproduce

create table l as
( select x from long_sequence(100) )

create table r as
( select x + 50 from long_sequence(100) )

select x
from l join r on l.x = r.x

and got back
Invalid column: r.x

Expected behavior
Tables should be joined, no SQL syntax error
