Problem adding Logstash to Kibana monitoring

Elastic Stack Logstash
1

Hi All,

I have a problem to add Logstash monitoring to Kibana. I have followed the configuration guidelines, but the Logstash widget does not appear on Kibana Monitoring tab.

My logstash.yml:
node.name: node-1
path.data: /var/lib/logstash
path.logs: /var/log/logstash
# X-Pack Monitoring
# https://www.elastic.co/guide/en/logstash/current/monitoring-logstash.html
xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: logstash_system
xpack.monitoring.elasticsearch.password: password
#xpack.monitoring.elasticsearch.url: ["http://192.168.16.124:9200"]
#xpack.monitoring.elasticsearch.ssl.ca: [ "/path/to/ca.crt" ]
#xpack.monitoring.elasticsearch.ssl.truststore.path: path/to/file
#xpack.monitoring.elasticsearch.ssl.truststore.password: password
#xpack.monitoring.elasticsearch.ssl.keystore.path: /path/to/file
#xpack.monitoring.elasticsearch.ssl.keystore.password: password

ES and Kibana appears on the Kibana"s Monoitoring tab, but Logstash does not.
Have you got any idea what have I missed? Thanks!

May I know which version of Elasticsearch, Kibana and Logstash you are using?

Also, just in case, if you haven't seen these are the instructions to configure logstash monitoring for latest version 6.5

3

Sorry, I did not mentioned the version - it is 6.4.1 (all of the products).
I have followed that instruction, but the expected result was not reached.

4

What is your cluster setup like? Do you have a single cluster for everything, or do you have a dedicated monitoring cluster?

5

It is a development site, so single cluster for everything.

6

Could you restart Logstash and post the first 50 lines of logs? I want to see if there are any errors or other messages related to Monitoring. Thanks.

Thanks,

Thanks for the log. I don't see anything abnormal there. Next, while your Logstash node is running, could you run curl -v http://localhost:9600/_node/pipelines from the same machine and post the results here?

Hi,
I have checked it the connection is refused.
I have checked the opened ports on the server and logstash does not opened any ports - although the port opening was ment to be successful in the log.
[2018-11-22T13:49:05,620][INFO ][logstash.agent ] Successfully started Logstash API endpoint {:port=>9600}

My colleague mentioned I may have to use JAVA setcap in order to open the port - but port 9600 is not privileged as far as I know?!
