Monitoring of task consumption has shown the `reports:monitor` task takes an aggressively high amount of cycles from Kibana Task Manager. This impacts the throughput of alerts. This first step is a serverless-only config change to give an immediate increase in overall task throughput. It's safe to lower this polling frequency: **the impact is limited to the responsiveness of retries** when a report job is found to be timed out. Long-term, the plan will be to tune other parts of the code: https://github.com/elastic/kibana/issues/170462 ## Testing 1. Adjust the Dev mode settings to match a value set in production. Add this to `config/kibana.dev.yml`: ``` xpack.reporting.capture.maxAttempts: 3 # usually in Dev mode, this is set to 1 ``` 2. Start the scripts in different terminal windows to run Elasticsearch and Kibana dev servers ``` yarn es serverless --------------- yarn serverless ``` 3. Open a search in Discover that covers about 4,000 hits and request a CSV export using the Share menu. 4. Monitor the Kibana server logs and wait until the background job begins. Restart the server while the job is executing (saving a file in code under `packages/` or `server/` will trigger a restart). 5. Around 3 minutes after restart, the report job will get a re-attempt Compare this behavior vs in non-serverless, where a report job will get a re-attempt around 3 seconds after restart. |

- Version Compatibility with Elasticsearch
- Questions? Problems? Suggestions?
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:
- Download the latest version on the Kibana Download Page.
- Learn more about Kibana's features and capabilities on the Kibana Product Page.
- We also offer a hosted version of Kibana on our Cloud Service.
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:
- CONTRIBUTING.md will help you get Kibana up and running.
- If you would like to contribute code, please follow our STYLEGUIDE.mdx.
- For all other questions, check out the FAQ.md and wiki.
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. | 7.15.1 | 7.15.1 | 💚 OK |
| ES patch number is newer. | 7.15.0 | 7.15.1 | ⚠️ Logged warning |
| ES minor number is newer. | 7.14.2 | 7.15.0 | ⚠️ Logged warning |
| ES major number is newer. | 7.15.1 | 8.0.0 | 🚫 Fatal error |
| ES patch number is older. | 7.15.1 | 7.15.0 | ⚠️ Logged warning |
| ES minor number is older. | 7.15.1 | 7.14.2 | 🚫 Fatal error |
| ES major number is older. | 8.0.0 | 7.15.1 | 🚫 Fatal error |
