8.1.1 Cannot display Logstash pipeline in monitoring UI

I have migrated the Elastic stack from 7.17.1 to 8.1.1. After the upgrade everything works fine, except the Kibana monitoring logstash pipeline viewer UI.

stack monitoring > logstash > pipelines

pipeline main points to https://fqdn/app/monitoring#/logstash/pipelines/main?_g=(cluster_uuid:cluster_id,refreshInterval:(pause:!f,value:10000),time:(from:now-15m,to:now))

After clicking on the main pipeline, I get an empty screen.

POST request https://fqdn/api/monitoring/v1/clusters/cluster_id/logstash/pipeline/main returns payload

"pipeline":{"data":null,"isBoom":true,"isServer":false,"output":{"statusCode":404,"payload":{"statusCode":404,"error":"Not Found","message":"Pipeline [main @ ] not found in the selected time range for cluster [cluster_id]."},"headers":{}}}}

Have you checked you pipelines, for example the ingestion pipelines after running the setup command for the various modules ?

Hi @zx8086, what can I check? All my Logstash pipeline config files are properly working (tested using logstash -t -f %s).

[2022-03-24T12:58:38,338][INFO ][logstash.agent] Pipelines running {:count=>1, :running_pipelines=>[:main], :non_running_pipelines=>[]}

How are you monitoring ? Metricbeat ? Logstash-xpack module ?

yes, correct

Would help to see the Logstash configuration as well as the metricbeat module configuration and logs. Metricbeat logs will show if the modules is working and data being sent not.


path.logs: /var/log/logstash
http.port: 9600
pipeline.ecs_compatibility: disabled
xpack.management.enabled: false
monitoring.cluster_uuid: "cluster_id"


- module: logstash
  xpack.enabled: true
  period: 10s
  hosts: [""]
  username: "remote_monitoring_user"
  password: "xxxxxxxxx"
    - node
    - node_stats

grep metricbeat /var/log/syslog


Configured this ?

monitoring.enabled: false

Also you can use a curl command to see if the http endpoint is working

sorry I left out lines below (/etc/logstash/logstash.yml)

# disable internal monitoring; replaced by metricbeat
monitoring.enabled: false
curl http://remote_monitoring_user:xxxxxxx@


Do you see the same calls reflected in the metricbeat logs ? Is metricbeat making the call to that same address, same credentials and having the same response ?

Also what about using the default settings? Metricbeat is running on the same node as logstash right ? So localhost should work too.

- module: logstash
  xpack.enabled: true
  period: 10s
  hosts: ["localhost:9600"]
  #username: "user"
  #password: "secret"```

localhost does not work as the port is not bound to all interfaces (but only to the IP adres

I only see metricbeat log events like Non-zero metrics in the last 30s in /var/log/syslog.


And if you remove the metricset ? that might be the problem

I have removed the metricsets and restarted the metricbeat service. Same issue. I have restored the config file and restarted the service again.

The logstash config you shared, was that the full one ? Hard to diagnose the issue on limited information.

yes, I only left out monitoring.enabled: false

This issue appears to be fixed in version 8.1.2
