Monitoring cluster logstash error

Elastic Stack Logstash
1

Hi all,

I currently have a ELK stack in product and have metricbeat setup on every node logstash instances pushing metric and monitoring data to a separate monitoring cluster.

Everything was working in 7.7.1, but since updating to 7.8 when i try and open the information tab on a specific logstash node, i receive a {"statusCode":404,"error":"Not Found","message":"Not Found"}

The information tab on a specific logstash node is that tab where you can see the persistent queue and jvm heap performance. Metricbeat is working as expected, i can see the systems CPU/Memory usage, and also the Events Ingested counter works.

Not sure whether this is a bug, or if I can fix it.

This is the logstash overview page that is working

This is from the system logs

Facing the same error after Upgrading and the Information Tab from the pipelines is also not showing here (Same 404 Message).

One thing i found was in Kibana Logs:

{"type":"log","@timestamp":"2020-06-26T13:04:48Z","tags":["debug","http","server","Kibana","cookie-session-storage"],"pid":21851,"message":"Error: Unauthorized"}
{"type":"log","@timestamp":"2020-06-26T13:04:48Z","tags":["debug","plugins","security","basic","basic"],"pid":21851,"message":"Trying to authenticate user request to /api/status."}
{"type":"log","@timestamp":"2020-06-26T13:04:48Z","tags":["debug","plugins","security","basic","basic"],"pid":21851,"message":"Cannot authenticate requests with `Authorization` header."}

Hopefully someone can support.

I have compared the urls from the working pipeline overview and the not working pipeline details:
https://host:5601/app/monitoring#/logstash/pipelines?_g=(cluster_uuid:VTDsWXH0TUqC4YO7H8Zhkw,refreshInterval:(pause:!f,value:10000),time:(from:now-1h,to:now))
https://host:5601/logstash/pipelines/central-syslog?_g=(cluster_uuid:VTDsWXH0TUqC4YO7H8Zhkw,refreshInterval:(pause:!f,value:10000),time:(from:now-1h,to:now))

The problem is that the part "/app/monitoring#" is missing in the lower url. adding this part produces the correct url

Update: Problem will be fixed with 7.8.1 https://github.com/elastic/kibana/pull/69861
