Seeing the message like Courier Fetch of 2 of 380 shards failed.

When this message shows up, so that relevant configuration at eleaticsearch/kibana can be set?

Hi,

This is mostly an elasticsearch error. And there are multiple reasons for it.
I did a search on this forum and here are the discussion posts: https://discuss.elastic.co/search?q=courier%20fetch%20error
Can you check these out and also give us more details on the conditions where you are seeing this error?

In Kibana - if you have scripted fields for any index patterns, they could also be a cause for this error.

Thanks,
Bhavya

No We don't have any scripted fields.

I see this error when the number of shards increases as we have the time series index.
