Grafana service started up, Grafana UI not starting up

karan_alang1 — Wed, 21 Dec 2016 03:32:02 GMT

Hi - i've installed Grafana on HDP 2.4 Sandbox, and started the service on Ambari.

--------------------------------------------

[root@sandbox opentsdb-2.2.1]# ps -ef | grep grafana ams 27134 1 0 19:04 ? 00:00:02 /usr/lib/ambari-metrics-grafana/bin/grafana-server --pidfile=/var/run/ambari-metrics-grafana/grafana-server.pid --config=/etc/ambari-metrics-grafana/conf/ams-grafana.ini cfg:default.paths.data=/var/lib/ambari-metrics-grafana cfg:default.paths.logs=/var/log/ambari-metrics-grafana

However, on launching the UI, it is not able to connect (pls see screenshot attached)

Any ideas on how to fix the issue ?

Hi All, i've upgraded Amabari to 2.2.2.0 (from 2.2.1) & then installed Grafana using the link below ->

I'm facing this issue, can you provide inputs on how to fix this.

I've followed this link to upgrade ambari & then install Grafana .. is there anything else that needs to be done ?

It seems like the Grafana daemon is up. Is your Virtualbox set up to port forward 3000?

If you do "curl http://localhost:3000" from inside the VM's SSH, what do you see?

Since Grafana was introduced in Ambari 2.2.2, the sandbox from an older version would not have had the port forwarding rule for Grafana UI that listens on port 3000.

@yusaku - yes, you are correct .. port forwarding rule for service Grafana & OpenTSDB was not there.

I added the port in port forwarding & the UI has come up. Thanks for your help in this!
