Grafana integration question

[benhank]

Howdi guys,

I have a project that involves using Grafana with elasticsearch. I seem to have run into a hiccup.
Here is a link to Grafana's docs on the topichttp://docs.grafana.org/datasources/elasticsearch/.
Its reads:

Code: Select all

Direct access

If you select direct access you must update your Elasticsearch configuration to allow other domains to access Elasticsearch from the browser. You do this by specifying these to options in your elasticsearch.yml config file.

http.cors.enabled: true
http.cors.allow-origin: "*"

but I cant find those lines in

Code: Select all

/usr/local/nagioslogserver/elasticsearch/config/elasticsearch.yml

Is there something im missing?
Thanks in advance!

Looks like it uses the Elasticsearch HTTP API to grab the data. I would try editing the following line:

Code: Select all

http.host: "localhost"

And changing it to:

Code: Select all

http.host: "0.0.0.0"

And restarting your Elasticsearch service. Though, you might want to change your firewall settings to only allow inbound traffic on 9200 from your Grafana box. Otherwise, any machine on the subnet would be able to write to or read from your Elasticsearch cluster.

sorry about this, that worked now it is asking me for an "instance name", where would i find that?

Good question. Is this NLS cluster behind a load balancer of some sort? Are you giving Grafana the address of a specific NLS node (assuming multiples exist)?

You could try giving it the cluster id or the specific instance id of the host you're connecting to. Here's mine:

Though i'm not sure why it would ever need a cluster/node ID to ask the HTTP API for things.

It's working!

here is the index name they want:

It sounds like this issue has been resolved. Is it okay if we lock this thread? Thanks for choosing the Nagios forums!

[benhank]

yup and thanks!

You're welcome!
