== REST calls and JSON Replies for Monitoring Data ==

Monitoring data collectors make REST calls to monitoring datastores.  Datastores reply with JSON data that conforms to a JSON schema that is specific to the type of REST call being responded to.
All of these schemas inherit from the [http://unis.incntre.iu.edu/schema/20120709/networkresource UNIS network resource schema] with the exception of the opsconfig schema.
This page gives examples of these REST calls and responses.
These examples assume the following (fictitious) local datastore URLs.
For simplicitly, we show one local datastore per aggregate here, but the architecture does ''not'' require that.  It is fine to have the data for an aggregate be split among multiple datastores.
 * `https://datastore.geni.net/`: datastore containing configuration data for operational monitoring
 * `https://datastore.instageni.gpolab.bbn.com/`: datastore for gpo-ig aggregate
 * `https://datastore.ch.geni.net/`: datastore for ch.geni.net authority
 * `https://datastore.externalchecks.geni.net/`: datastore for external checks in the monitoring framework (e.g. inter-aggregate pings, AM external availability)

==== Aggregate call and response ====

Retrieves information about an aggregate, including lists of resources and slivers at that aggregate, version information, and where to look for measurements about the aggregate.

General form of the REST call:
{{{
https://<datastore-host>/info/aggregate/<aggregate-id>
}}}

<aggregate-id> is usually the aggregate's GENI-assigned nickname (short name).

Example REST call for aggregate gpo-ig:
{{{
https://datastore.instageni.gpolab.bbn.com/info/aggregate/gpo-ig
}}}

The response conforms to the [http://www.gpolab.bbn.com/monitoring/schema/20140828/aggregate# aggregate schema], [http://www.gpolab.bbn.com/monitoring/schema/20140828/aggregate.schema.jwc commented version of the aggregate schema].
