This better reflects its purpose as otherwise it would imply
that you need Elastic Stack for it. Graylog also reads from
Elasticsearch instances, this could serve as additional integration
here.
Main focus: Object attributes and their value types. Originates from the
API Event Streams patch to document their value types. Now applied to
the entire configuration objects chapter.
The API chapter and their value types has been changed to capitalized
type identifiers.
Value types are now explicitly told about inside monitoring basics. This
has been adopted into the Icinga 2 training material a long time ago
and finds its way into the docs too.
The CheckResult and PerfdataValue value types have been moved into the
advanced topics chapter. mkdocs doesn't like multiple `#` headings in one file
and did just hide it.
Also moved the Influxdb details into the features documentation where it
belongs.
Many small references and URLs to other chapters added.
E.g. dedicated chapters for object accessor examples, to better link against
time dependent thresholds.
Can serve as patch basis and reference for ITL documentation where the
value types are missing too.
This commit also fixes the non-requirement of "legacy-timeperiod" which
also is a default template import since 2.6.
This also fixes the state mapping issue.
fixes#4015
* Rename files to allow easy ordering
* Update links inside markdown according to new file names
* Move HTML links (<a>...</a>) to the end of the header lines
* This is necessary to allow mkdocs to parse headers correctly and display them in the TOC
* Following sed command was used: sed -i .bu 's/\(<a.*a>\) \(.*\)/\2 \1/g' $filename
Also apply a new structure.
Deleted the old cluster and client documentation and started "fresh".
This commit also includes various images used in the newly written
"Distributed Monitoring" chapter for better understanding.
