I didn't do a full review, but @mikecote asked me to have a look at the migration changes, and those look peachy. 💯 |
|
Hi, sorry I need a little more time looking at this. I pulled it down, and getting a server crash, but there's a chance it's because my ES is messed up or other reasons. Also, there are 2 conflicts that need to be resolved on this PR |
|
I think I keep hitting stuck migrations, even when I clear all my documents out. I can fix the problems with missing shards in the indices (hence why they are red) but for now, this is causing Kibana to completely crash. I'll need to look a little more to see if this is just a distraction |

I'd feel way more comfortable if the SavedObjects/Migration changes were split into a separate PR from this one. |
|
@joshdover I have moved it to another PR #41815, will update this one once merged. 👍 |

@joshdover The migration changes have been removed from this PR now that they are in master. Let me know if this looks good to you now. |
💚 Build Succeeded |

In this PR, we're making the following changes to the task manager to support having better error handling for alerting and actions:
10s)10s)maxAttemptsconfigurationmaxAttemptshas a minimum of 1getRetryDelayfunction to return delay in seconds to wait before attempting the task againmaxAttemptsconfiguration now behaves like maximum total attempts and not how many retries after first failurerunAtis no longer extended by timeout when the task runsFixes #40872
Dev-Docs
Task manager now uses saved objects
Starting up kibana will convert
.kibana_task_managerto an alias and indices will follow the.kibana_task_manager_1syntax. A migration will execute to prefix the ids withtask:as it converts to saved objects.
