    585 On the list of services we can see the tool daemons for OWAMP and BWCTL. We can also see the perfSONAR services storing the Ping and OWAMP data from the tests we've configured. From this page we can query a given service to see the corresponding data. The active measurement data is stored on the node that initiates the measurements and is served by a perfSONAR service running on that node. For example, we can query the perfSONAR BUOY OWAMP MA on node PCA to see the OWAMP data from PCA to PCB.

    587587''NOTE: When querying a single service, perfAdmin will first fetch all the metadata stored on that service. After obtaining the metadata, perfAdmin queries the service for data in order to build summaries and distinguish between active and inactive data sets. This process may take some time if there are many measurements stored on a given service.''

    591591In this particular case we only have one OWAMP measurement stored at this service. We can graph by selecting a time range from the select box. perfAdmin will query the service for all data points within the last X hours and plot those (data points might be aggregated depending on granularity). The graphs are a little bit interactive, e.g. you can mouse over different data points and see the values for each direction.
