Raspbian builds were running on Ubuntu 20.04 but with qemu-user-static from Ubuntu 21.10 (impish) due to need for newer features. However, the impish package repos are no longer available as that version reached its EOL. ubuntu-latest still refers to 20.04 on GitHub Actions but 22.04 is already available when explicitly specified. This commit switches the build over to that version and removes the workaround.
The point of logging to the Windows Event Log was to catch errors that happen
before the full logging configuration has been loaded and enabled. Messages
like the number of loaded objects per type just cause noise in the log and
provide little benefit. Therefore raise the required log level at this stage.
Note that this commit removes the (never documented) ability to use the -x flag
to change the level. But doing so would require patching the command line of
the service in the registry anyways.
Almost every Icinga 2 node setup requires the Icinga 2 API, as Icinga
Web connects to it, Icinga DB requires it, and although it's not clearly
mentioned anywhere in the documentation at the moment, it enables the
cluster communication functionality.
If some kind of query is not supposed to be processed at the moment, there is
little point in checking it. During a full dump, state updates are suppressed
(i.e. delayed), so when a dump takes very long, this would have resulted in a
false Redis backlog warning.
The check makes no attempt to explicitly connect to Redis, it uses the
connection of the IcingaDB feature, so this message better describes the state
in this situation.
IcingaDB::GetConnection() uses IcingaDB::m_Rcon which is only initialized in
IcingaDB::Start(), therefore add a nullptr check to the check command.
Additionally, as m_Rcon is potentially accessed concurrently, add a copy of the
value that is safe for concurrent use.
icingadb-web shows multiple lines from the check output collapsed into a single
line. The lines containing just minuses make this look cluttered and making
making it a heading provides little to no benefit. Even when rendering markdown
in the check output at some point, having the lists labeled using normal
paragraphs would look just fine.
- Add icinga2_ and icingadb_ prefixes to make clear which component is
responsible for the value.
- Rename heartbeat_lag to heartbeat_age, describes it better in my opinion and
sound a bit less like something that should be as close to zero as possible.
- Rename redis_dump/database_sync into full_dump/full_sync as this is how these
operations are refered to in log messages as well.
- Rename Redis backlog into Redis query backlog, makes it a bit clearer in my
opinion.
- Rename runtime_backlog into runtime_update_backlog, as the component in
Icinga DB is called that way and this naming is also exposed in log messages.
- Rename dump_config/state/history into config/state/history_dump, makes it
sound more natural.
