I have a question regarding Gray Log 2
In the company I work for all systems report exceptions to Gray Log server which has predefined streams.
I need to build an external Dashboard which retrieves data from different streams. I haven't found any Gray Log 2 API to use for this. I read that there is a possibility to query Elastic Search directly. Can you please advise how do I do so or if there is any Gray Log 2 API.
My Dashboard will be written or in JSF or in .NET still not sure about which is best to use.
I would be very grateful for detailed answer on this question. Links will help too.
Graylog2 has a very clear and complete Restful API, that you can browse/test with Swagger.
Go to System -> Nodes and select "API Browser" from a node action dropdown menu.
By default, you can access it at the following url : http://your.graylog2:12900/api-browser
Hope this helps !
