APM 10.7 HF#39 and grafana 6.7.1 open source installed in separate servers.
APM is in cluster mode (1 MoM, 3 Collectors).
Integration has been configured but the SimpleJSON data source to use the grafanarest service and retrieve APM metrics seems to have issues.
Testing data source returns a message "Network request failed" or the message "Failed to fetch".
Using IE to open grafana GUI.
Enabled debug level in grafana side, the only error message was : "Failed to get plugins repo from grafana.com, Get https://grafana.com/api/plugins/versioncheck?slugIn=mxswat-separator-panel,farski-blendstat-panel,novatec-ca-apm-datasource,grafana-simple-json-datasource,michaeldmoore-annuciator-panel,snuids-trafficlights-panel,smartmakers-trafficlight-panel&grafanaVersion=6.7.1: net/http: request canceled while waiting for connection (Client. Timeout exceeded while awaiting headers)"
Release : 10.7.0
Component : APM Agents
Workaround:
Lower the security settings of IE to make it work. (Internet Options --> Security).
It seems that the call is using the local browser to hit grafanarest api, even if we set the Access filed in grafana data source to be "Server" and not Browser.
