| − | All these resource information are put into gCube Information System (IS) which plays the role of the infrastructure's registry and supports the publishing, discovery and monitoring of all the parts that form the infrastructure. D4Science provides two monitoring tools, namely Fast Monitoring and Infrastructure Viewer, in order to provide quick organization and visualization of the resources and how they are related to each other. The tools are accessible at the [http://monitor.d4science.research-infrastructures.eu/ Monitoring Webtool].

| − | == Fast Monitoring ==
| + | |
| − | The [http://monitor.d4science.research-infrastructures.eu/fast-monitoring/ Fast Monitoring], shown in figure bellow, is the default tool where the user is also redirected by following the [http://monitor.d4science.research-infrastructures.eu/ Monitoring Webtool] link.

| − | The first step is to select a virtual organization (VO) and/or a virtual research environment (VRE) from a the drop-down list at the left hand side corner of the interface, called '''Select VO'''.
| + | |
| − | | + | |
| − | The main section is divided into two main panels. The left, organizes D4Science Resources in three manners.
| + | |
| − | | + | |
| − | * '''Resource Type''' contains general information about resources (gHN nodes, running instances e.t.c.) registered to the selected VO/VRE.
| + | |
| − | | + | |
| − | * '''WS Resource Type''' organizes information according to stateful resources maintained by specific Web Service running instances of a VO/VRE.
| + | |
| − | | + | |
| − | * '''Map''' where it binds information about resources to their geographical location.
| + | |
| − | | + | |
| − | The right panel, presents details about the selected (from the left panel) resources. The figure above for example, shows the fast monitoring tool presenting the gCube Hosting Nodes (gHNs) registered to the ''d4science'' VO/VRE. Selecting a specific resource from the upper window refreshes the lower one with detailed information about that gHN in an XML-like manner. Similarly, one can gather information about other types of objects like ''Generic Resources'' or ''Running Instances''. The next figure shows the fast monitoring tool, providing geographical information of running services in Athens.

| − | == Infrastructure Viewer ==
| + | |
| − | The interface is provided at [http://monitor.d4science.research-infrastructures.eu/iv/ Infrastructure Viewer] and a screenshot is shown below.
| + | |
| − | | + | |
| − | [[Image:Iv-mon.jpeg|frame|center|The Infrastructure Viewer monitoring tool.]]
| + | |
| − | | + | |
| − | This webtool has been designed to provide different views for various purposes. Views can be for
| + | |
| − | | + | |
| − | * '''gHN''' (Sites, gCube Hosting Nodes, and Running Instances)
| + | |
| − | * '''Package''' (Service Archives, and Software Packages, and gHNs)
| + | |
| − | * '''Service''' (Service Classes, Service Names, and Running Instances)
| + | |
| − | * '''Data''' (Collections, Metadata Collections, and Indices)
| + | |
| − | * '''Package Dependencies'''
| + | |
| − | * '''Service Dependencies'''
| + | |
| − | | + | |
| − | Each view can be applied on a specific scope identified by:
| + | |
| − | | + | |
| − | * the '''Infrastructure''',
| + | |
| − | * the '''Virtual Organization''', and
| + | |
| − | * the '''Virtual Research Environment'''.
| + | |
| − | | + | |
| − | Additionally, each view provides specific metrics like CPU or disk space for gHNs, indices and meta-data collections for data, e.t.c.
| + | |
| − | | + | |
| − | The above figure depicts a spacial view for packages in d4science infrastructure for the FCPPS/FCPPS VO/VRE according to some metrics selected under the Advanced Options drop-down list.
| + | |
| | | | |
| − | Living the cursor of the mouse above a resource, additional information is provided through a caption area. Additionally, for gHN and Services views, right-clicking on a resource, results in a pop-up window, that organizes full and detailed information, as it is depicted bellow.
| + | All these resource information are collected by the [[gCore Based Information System]] (IS) which plays the role of the infrastructure's registry and supports the publishing, discovery and monitoring of all the resources belonging the infrastructure. A working instance of the Infrastructure Monitor is available in the [https://services.d4science.org/infrastructure-monitor D4Science Services Gateway]. |

Hardware resources include gCube hosting nodes (containers) as well as gLite storage elements, computing and Cloud nodes, while gCube services and external software fall into the second category type. Collections and auxiliary resources can be data, metadata, indices, schemas or transformation utilities, among others.
