This adds the page of the new manticore output plugin, fluent/fluent-bit#12585:

  • configuration parameters (every config_map key plus workers), TLS/SSL, record IDs and bulk retries, laid out as the Elasticsearch and HTTP output pages;
  • Shared mode, which loads a finite source into one table with the Manticore bulk_import feature;
  • examples for the command line, a Regular configuration and a Shared file load, in YAML and classic format.

It also adds the page to SUMMARY.md, Manticore Search to the Vale heading exceptions and Manticore to the spelling list.

The plugin is not in a released image yet, so the example validation against fluent/fluent-bit:latest fails until the code is released; with a build of the plugin branch all four examples pass fluent-bit --dry-run. Please add the waiting-on-code-merge label. Vale reports nothing for the new page.

Summary by CodeRabbit

  • Documentation
    • Added Manticore Search to the outputs table of contents and documented the output plugin.
    • Explained supported records, configuration, TLS, and record IDs, along with how Regular and Shared modes handle ingestion, retries, and publication.
    • Included command-line and configuration examples for regular ingestion and loading a finite file in Shared mode.

Add the page of the out_manticore output plugin: its parameters, record
IDs, bulk retries of Regular mode, Shared mode for loading a finite
source with bulk_import, and Regular and Shared examples. Add the page
to SUMMARY.md, and Manticore Search to the Vale heading exceptions and
spelling list.

The new guide may lead users to expect a supplied record ID to be preserved, although its /bulk example does not use the documented ID position. This is a narrow documentation issue with a straightforward example correction.

include service.grace and [SERVICE] Grace guidance sized for the expected load,
so Fluent Bit has enough shutdown time to finish pending output work when
exit_on_eof is enabled.

in the operation object, while keeping the document fields inside `doc`.

A Shared load that still has records to send when Fluent Bit exits stays
unpublished, and the default grace is 5 seconds. Show grace in the file
load example.

@tomatolog I reviewed the page against the plugin code in fluent/fluent-bit#12585 and have 7 fixes: the empty-load complete log, the full Finish conditions, the unknown-result logging, the &shared=<n> and &shared_join URIs, the non-map drop, the timestamp not being sent, and the http_passwd default.

I don't have write access to your fork, so here is a patch on top of 11f8373:

  - Shared mode: document that no Finish is sent, yet `complete` is
    still logged, when no data request succeeded (for example an empty
    source)
  - Shared mode: list the full Finish conditions, including at least
    one successful request, no permanent failure and no exhausted
    retries, and note that a request that succeeds on retry doesn't
    block the Finish
  - Shared mode: state that an unknown Finish result also logs `failed`
    but doesn't name the PURGE statement
  - Shared mode: document the `&shared=<n>` and `&shared_join` URI forms
  - Record IDs: say a non-map record drops the whole flush without a
    retry
  - Record IDs: state that only the record body is sent, without the
    Fluent Bit timestamp or metadata, and link the Record Modifier
    filter
  - Parameters: fix the `http_passwd` default to empty

The Record Modifier filter adds only static keys and cannot put the
event timestamp into the record body; the Lua filter gets the timestamp
in its callback. With shared_indexers 0 the plugin sends a bare
&shared, which lets the daemon choose the pool size, so &shared=<n> is
sent only for a positive n.

@eschabell thanks for the careful review and the patch. It's in as f886770 with your authorship and sign-off, plus 01f1d81 with two corrections on top:

  • the Record Modifier filter only adds static keys, so it can not put the event timestamp into the record body; the timestamp example now points to the Lua filter which gets the timestamp in its callback
  • with shared_indexers 0 the plugin sends &shared and the daemon picks the pool size, so &shared=<n> is only sent for a positive <n>.

About write access: GitHub can not give maintainers push access to pull request branches in organization-owned forks, so the owner of our fork has invited you as a collaborator with write access to manticoresoftware/fluent-bit-docs. Once you accept the invitation, you can push to out_manticore directly.
