 This is a proxy-like service translating [grafana simplejson](https://github.com/grafana/simple-json-datasource)  data source calls into calls to [ServiceNow](https://www.servicenow.com/) REST API getting the items from incident table. Effectively allowing allowing integration of grafana dashboard with ServiceNow.

If you your goal is to get information about incidents beeing "in-progress" in your assignemnt group just adjust the filter with appropriate value instead of "YOURASSIGNEMNTGROUP" used in the example snow-grafana-proxy.conf
