# datasource describe a way to get prometheus metrics.
# Properties :
# - name: name of the query. To be used in edges or nodes mainstatquery or secondarystatquery. Result will be output in mainstat, or secondarystat.
# - address: the address of prometheus.
# - query: prometheus query. Same as typed in prometheus graph page.
# - type: type of query. "query" will get instant value, "query_range" will get all samples for the grafana period. Result will be averaged.
# - timeout: query timeout in seconds.

# graphs identifies context for a nodegraph. You can have many contexts, and your grafana query will mention this context name.
#  For this example named "internet", grafana URL will be :
#   Edges: http://nodegopher.local.lan:8080/internet/edges?from=$__from&to=$__to&interval=$__interval
#   Nodes: http://nodegopher.local.lan:8080/internet/nodes?from=$__from&to=$__to&interval=$__interval
# Properties :
# - name: name of the context
# - nodes: list of nodegraph nodes
# - edges: list of nodegraph edges
