[Task Manager] cancel expired tasks as part of the available workers check (#88483)
When a task expires it continues to reside in the queue until `TaskPool.cancelExpiredTasks()` is called. We call this in `TaskPool.run()`, but `run` won't get called if there is no capacity, as we gate the poller on `TaskPool.availableWorkers()` and that means that if you have as many expired tasks as you have workers - your poller will continually restart but the queue will remain full and that Task Manager is then in capable of taking on any more work. This is what caused `[Task Poller Monitor]: Observable Monitor: Hung Observable...`

Kibana

Kibana is your window into the Elastic Stack. Specifically, it's a browser-based analytics and search dashboard for Elasticsearch.

Getting Started

If you just want to try Kibana out, check out the Elastic Stack Getting Started Page to give it a whirl.

If you're interested in diving a bit deeper and getting a taste of Kibana's capabilities, head over to the Kibana Getting Started Page.

Using a Kibana Release

If you want to use a Kibana release in production, give it a test run, or just play around:

Building and Running Kibana, and/or Contributing Code

You might want to build Kibana locally to contribute some code, test out the latest features, or try out an open PR:

Documentation

Visit Elastic.co for the full Kibana documentation.

For information about building the documentation, see the README in elastic/docs.

Version Compatibility with Elasticsearch

Ideally, you should be running Elasticsearch and Kibana with matching version numbers. If your Elasticsearch has an older version number or a newer major number than Kibana, then Kibana will fail to run. If Elasticsearch has a newer minor or patch number than Kibana, then the Kibana Server will log a warning.

Note: The version numbers below are only examples, meant to illustrate the relationships between different types of version numbers.

Situation Example Kibana version Example ES version Outcome
Versions are the same. 5.1.2 5.1.2 💚 OK
ES patch number is newer. 5.1.2 5.1.5 ⚠️ Logged warning
ES minor number is newer. 5.1.2 5.5.0 ⚠️ Logged warning
ES major number is newer. 5.1.2 6.0.0 🚫 Fatal error
ES patch number is older. 5.1.2 5.1.0 ⚠️ Logged warning
ES minor number is older. 5.1.2 5.0.0 🚫 Fatal error
ES major number is older. 5.1.2 4.0.0 🚫 Fatal error
