Migrate docs from AsciiDoc to Markdown. The preview can be built after #212557 is merged. @florent-leborgne please tag reviewers, add the appropriate label(s), and take this out of draft when you're ready. Note: More files are deleted than added here because the content from some files was moved to [elastic/docs-content](https://github.com/elastic/docs-content). **What has moved to [elastic/docs-content](https://github.com/elastic/docs-content)?** Public-facing narrative and conceptual docs have moved. Most can now be found under the following directories in the new docs: - explore-analyze: Discover, Dashboards, Visualizations, Reporting, Alerting, dev tools... - deploy-manage: Stack management (Spaces, user management, remote clusters...) - troubleshooting: .... troubleshooting pages **What is staying in the Kibana repo?** - Reference content (= anything that is or could be auto-generated): Settings, syntax references - Release notes - Developer guide --------- Co-authored-by: Florent Le Borgne <florent.leborgne@elastic.co>

Task Manager settings in {{kib}} [task-manager-settings-kb]
Task Manager runs background tasks by polling for work on an interval. You can configure its behavior to tune for performance and throughput.
Task Manager settings [task-manager-settings]
xpack.task_manager.max_attempts- The maximum number of times a task will be attempted before being abandoned as failed. Defaults to 3.
xpack.task_manager.poll_interval- How often, in milliseconds, the task manager will look for more work. Defaults to 500 and cannot be lower than 100.
xpack.task_manager.request_capacity- How many requests can Task Manager buffer before it rejects new requests. Defaults to 1000.
xpack.task_manager.max_workers- [8.16.0] The maximum number of tasks that this Kibana instance will run simultaneously. Defaults to 10. Starting in 8.0, it will not be possible to set the value greater than 100.
xpack.task_manager.monitored_stats_health_verbose_log.enabled- This flag will enable automatic warn and error logging if task manager self detects a performance issue, such as the time between when a task is scheduled to execute and when it actually executes. Defaults to false.
xpack.task_manager.monitored_stats_health_verbose_log.warn_delayed_task_start_in_seconds- The amount of seconds we allow a task to delay before printing a warning server log. Defaults to 60.
xpack.task_manager.event_loop_delay.monitor- Enables event loop delay monitoring, which will log a warning when a task causes an event loop delay which exceeds the
warn_thresholdsetting. Defaults to true. xpack.task_manager.event_loop_delay.warn_threshold- Sets the amount of event loop delay during a task execution which will cause a warning to be logged. Defaults to 5000 milliseconds (5 seconds).
xpack.task_manager.capacity- Controls the number of tasks that can be run at one time. The minimum value is 5 and the maximum is 50. Defaults to 10.
Task Manager Health settings [task-manager-health-settings]
Settings that configure the Health monitoring endpoint.
xpack.task_manager.monitored_task_execution_thresholds- Configures the threshold of failed task executions at which point the
warnorerrorhealth status is set under each task type execution status (understats.runtime.value.execution.result_frequency_percent_as_number[${task type}].status).This setting allows configuration of both the default level and a custom task type specific level. By default, this setting is configured to mark the health of every task type as
warningwhen it exceeds 80% failed executions, and aserrorat 90%.Custom configurations allow you to reduce this threshold to catch failures sooner for task types that you might consider critical, such as alerting tasks.
This value can be set to any number between 0 to 100, and a threshold is hit when the value exceeds this number. This means that you can avoid setting the status to
errorby setting the threshold at 100, or hiterrorthe moment any task fails by setting the threshold to 0 (as it will exceed 0 once a single failure occurs).
