Type=index_not_found_exception

Hey @boostmachine

just chiming in

I see you cluster is in Yellow, From you curl command it shows the the index [my-index] is not there.Do you have a index called [My-index] or any stream connect to [My-index] ?
As you posted above you have couple indices in yellow and one called myservicename

yellow open myservicename 1Th-Nn-LRqSlEJ2-uzUdJw 1 1 0 0 208b 208b

cURL example, this command is a littile better when adding ?v

curl 'localhost:9200/_cat/indices?v'

Thes maybe danggling indices but not 100% sure. You can check by

curl -X GET "localhost:9200/_dangling?pretty"

You logs show

 No JobDefinition for archiving restore action found!

I assume you have Graylog 5 installed? By chance is this Opensource install or do you have a license?

Are you using security plugin with Opensearch?

In my personal documentation for the reasons why the indices are in yellow…

  • You have restarted a node
  • Node crashes
  • Networking issues
  • Disk space issues
  • Node allocation awareness
  • Shard has exceeded the maximum number of retries

From you first post

Try to remake the widget again but it seams that you had a index for that widget but now it gone and/or renamed.

I found this post , perhaps it will help.
