Hi All,
This is my server output after starting the api-server:

apm-server:

@kranthi_851 You're actually in good shape here. The curl output is showing that apm-server responded to a GET / with a 404 Not Found, so the connection is established successfully. apm-server does not log 404s - the logs you're seeing are actually an agent requesting GET /healthcheck, which is returning 200 as expected.

In an upcoming release, GET / will return a 200 with some basic server information to help avoid this confusing situation.

Thanks for your reply, but i am unable to view those logs in the apm-server may I know reason for that!1

kranthi_851 · August 30, 2018, 5:28am

And if run the apm-agnet jar file I am getting this error:
[root@TCHK1 apm-agent]# java -jar elastic-apm-agent-0.6.2-sources.jar
no main manifest attribute, in elastic-apm-agent-0.6.2-sources.jar

Please check it.

@kranthi_851 Almost there! You're running into a change introduced in the 6.4.0 UI, detailed in the release notes. You need to update either apm-server.yml or kibana.yml to ensure the index patterns match between where apm-server will store documents and where kibana will try to retrieve them.

Senz79 · August 30, 2018, 1:56pm

Put the below setting in Kibana.yml

apm_oss.errorIndices: apm-*
apm_oss.spanIndices: apm-*
apm_oss.transactionIndices: apm-*
apm_oss.onboardingIndices: apm-*

kranthi_851 · August 31, 2018, 5:29am

Thanks Again gil, its working fine.
Could you please suggest me to run the ./apm-server -e script continuously, since If I press ctrl+c apm-server getting stopped. I need continuous monitoring so how can we do that?

kranthi_851 · August 31, 2018, 5:30am

Thanks for you valuable response, its working fine now.

How have you installed the APM Server? If you installed via APT or YUM, you can follow the instructions in the docs to start the server when your machine boots: Quick start with Elastic Cloud | APM User Guide [8.11] | Elastic.

kranthi_851 · August 31, 2018, 6:05am

Thanks for the response it looks fine now.
