I'm trying to set up the WebAPI so I can use Grafana with NetXMS but I'm running into some issues. I have the netxms-websvc-2.2.6.war file (renamed to webapi.war) - tried both downloading it and building it myself with Maven, didn't make a difference. I've placed the file in the C:\NetXMS\WebUI\WebUI\webapi directory together with a jetty-web.xml file with the following content:

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="contextPath">/webapi</Set>
  <Set name="war"><SystemProperty name="jetty.home"/>\webapi\webapi.war</Set>
  <Set name="tempDirectory">webapi</Set>
</Configure>

I've added the following line to the Params value under HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Apache Software Foundation\Procrun 2.0\nxWebUI\Parameters\Start:

C:\NetXMS\WebUI\WebUI\webapi\jetty-web.xml

So far, so good, the problem is that when I open http://localhost:8080/webapi/ in the browser I get this:

{"description":"Internal error","error":46}

When I enter http://172.16.1.70:8080/webapi/ in the Grafana new datasource settings and click on "Save & Test", I get a "HTTP Error Bad Request" error.

Any ideas how to get this working?

Thanks
