Hi Guys.
I'm having trouble setting up the WebAPI for use with Grafana (v5.2.2). When I try to setup the Data Source with the below parameters (screenshot attached):
URL: http://fahad-dell-desktop.fy.it.cx:8100/ (I have set it to use 8100 during setup. )
Access: Server (default)
Basic Auth (checked)
With Credentials (checked)
(all SSL/TLS related options unchecked)
User: admin
Password: <entered correctly>
I ran a packet capture on my Grafana server to capture the request and response and they are posted below:
Request:

It's evident that Grafana is correctly trying to Post to the /sessions URL (as mentioned in the wiki https://wiki.netxms.org/wiki/Web_service_API) but the WebAPI is saying POST is not an allowed method for /sessions.
UPDATE
OK so it turns out my Web API war file wasn't set up correctnly (typo in jetty-web.xml). Fixing that resolved the issue.
