Um, I didn't quite get the point of adding a new field, we could use inst.GetHost() to get the value anytime.

[JaySon-Huang]

I try to make the message contains in Entry clear and eliminate the ambiguity. If there exist fields port, componentName along with inst, should I get the port from inst.GetPort() or get the name from inst.ComponentName()?
However, keeping inst instead of adding host is more flexible.

I can keep inst instead of adding host if you insist.

[AstroProfundis]

Yes I would still suggest using inst as it carries more information.
