Conversation
There was a problem hiding this comment.
Pull request overview
Adds Mattermost v12.0 documentation for post delivery audit logging (new audit level audit-delivery / ID 104) and wires it into the logging, compliance, and configuration docs so admins understand how to enable and ingest delivery records.
Changes:
- Document
audit-delivery(ID104) behavior and limitations (not written by the built-in audit log file target) and link to the new feature page. - Add a new compliance doc page describing prerequisites, configuration, record format, and interpretation for post delivery audit logging.
- Update related compliance/audit schema docs and Content Flagging/Data Spillage Handling docs to reference and configure the feature (plus unrelated regenerated Agents docs updates).

- Line 18: Update the feature label in the compliance documentation to
“Post-delivery audit logging” at both occurrences, while keeping the existing
link target unchanged.
- Line 26: Update the description for the embedded JSON audit log schema
documentation link to describe the JSON structure of Mattermost audit log
entries, replacing the configuration-oriented wording while preserving the
existing link target.
In `@source/administration-guide/comply/post-delivery-audit-logging.rst`:
- Around line 203-205: Update the deduplication guidance to match its stated
purpose of producing a distinct user list: group only by actor.user_id and
meta.post_id, removing meta.mechanism from the key, while retaining the earliest
timestamp as the first delivery.
In
`@source/administration-guide/configure/environment-configuration-settings.rst`:
- Line 3935: Update the audit-delivery configuration guidance to explicitly
instruct adding {"id": 104, "name": "audit-delivery"} to a target’s levels list
under ExperimentalAuditSettings.AdvancedLoggingJSON. Present this as an ..
important:: admonition stating that delivery records are discarded without a
consuming target, and link to the existing post-delivery audit logging example
and advanced logging target format.
In `@source/administration-guide/configure/site-configuration-settings.rst`:
- Line 2262: Update the post delivery audit logging descriptions to state that
entries are recorded for each eligible message delivery, reflecting exclusions
such as direct and group message channels. In the all-channel setting
description, replace “all channels” with “all eligible channels”; apply the same
eligibility wording to the repeated descriptions identified in the diff.
- Around line 2264-2266: Change both post-delivery audit logging admonitions to
important admonitions, preserving the prerequisites for
MM_FEATUREFLAGS_POSTDELIVERYTRACKING and server restart, and explicitly state
that an audit target consuming audit-delivery is required to retain records.
Apply the same fix in `@source/administration-guide/manage/logging.rst` around
lines 700 - 702: Add the same warning before the enablement procedure.
In `@source/administration-guide/manage/admin/content-flagging.rst`:
- Around line 62-69: Update the post delivery audit logging documentation in
source/administration-guide/manage/admin/content-flagging.rst lines 62-69 and
source/administration-guide/manage/logging.rst lines 695-697 to state that
audit-delivery records deliveries to users, plugins, and outgoing webhooks in
eligible channels. Explicitly document that direct and group message channels
are never eligible, regardless of the Record deliveries in setting.
In `@source/administration-guide/manage/logging.rst`:
- Line 217: Update the v11-or-later audit logging examples and their related
descriptions near the referenced configuration sections so they no longer
contradict the v12.0 default of 10,000 buffered records: separate v11 and v12
guidance or clearly label 1,000 as an intentional lower-cap setting, and ensure
each example’s maxqueuesize value matches its stated version.

Should it be more specific that it needs to be using the Advanced Audit log target ?
|
|
||
| Delivery records are written at the ``audit-delivery`` log level, ID ``104``. Unlike the other :ref:`audit log levels <administration-guide/manage/logging:log levels>`, ``audit-delivery`` isn't written by the built-in audit log file target, so enabling ``ExperimentalAuditSettings.FileEnabled`` doesn't capture delivery records. Add a target that consumes level ``104`` to ``ExperimentalAuditSettings.AdvancedLoggingJSON`` instead. See :ref:`advanced logging <administration-guide/manage/logging:advanced logging>` for the available target types and options. | ||
|
|
||
| We recommend a dedicated target, so that the volume of delivery records doesn't overwhelm your other audit records. The example below writes delivery records to their own file, rotated at 100 MB, with up to 10,000 records buffered in memory while writing: |

@harshilsharma63 is this example of the file target one that we ran through our load testing?
There was a problem hiding this comment.
I haven't run the load tests as the same code worked with DB backed logging, but I think I should run the tests again anyways. Locally this is the config I tested with. I'll update here with the load test result if we need to increase the log file size. Thats the only variable I think that could need tweaking and the 10k buffer is right.
