Deprecate phosphor-hostlogger?

Deprecate phosphor-hostlogger?

Hello,

Does anyone have opinions on if we deprecate phosphor-hostlogger?

I ended up becoming the "maintainer" of it due to the original maintainers
no longer being able to contribute to OpenBMC.  I've read through the
README and it is very much not clear to me what advantages it has over
using the similar functionality contained in obmc-console directly.
There is some mention of rsyslog and logrotate integration, but
obmc-console already supports a logrotate-like functionality, and I
think rsyslog could be easily configured to pick up the log files
created by obmc-console, if someone were so inclined.

It appears to only be used by the following meta layers:

    * meta-amd
    * meta-ampere
    * meta-bytedance
    * meta-quanta / s6q
    * meta-tyan
    * meta-yadro

It seems that this repository also incurred some bmcweb support that is
enabled for most systems (by default), even though they do not have the
corresponding daemon.

Can any of the system owners above comment as to what functionality they
are gaining by using phosphor-hostlogger over using obmc-console
directly?  Is this some functionality missing from obmc-console or is it
just a relationship between host logging, bmcweb and rsyslog that we
need to add?

I'm not aware of any bmcweb users. Since the feature was merged it has
been relatively quiet in terms of additions/bug fixes.  I'm in support
of removing/deprecating it.
