This user documentation describes usage of the GOCDB4 Central Visualisation Portal. This portal presents a view of topology and resources information for the whole EGI infrastructure. This consists mainly of:

  • Participating National Grid Initiatives (NGI)
  • Grid Sites providing resources to the infrastructure
  • Resources and services, including maintenance plans for these resources
  • Participating people, and their roles within EGI operations

GOCDB version supported in this documentation: 4.0 (August 2010)

Getting Started

Accessing GOCDB4 central visualisation portal

To access the web interface, you need an X509 digital certificate installed in your browser, delivered by one of the recognised EU-Grid-PMA Certification Authorities.

How is the information organised?

The following sets of information in GOCDB4 are organised in a similar way to GOCDB3:

  • Sites and related information
  • Service endpoints and related information
  • Groups (NGIs, ROCs, Countries) and related information
  • Users and related information
  • Downtimes and related information

Main changes between GOCDB3 and GOCDB4 are related to:

  • Nodes and related information: the notion of node disappears in GOCDB4 and is replaced by the notion of "service endpoints"
  • Groups in GOCDB4 are a generic replacement of specific groups such as ROC or Country.

Other documentation and help

If you want (or need) to know more about GOCDB4, please browse GOCDB Documentation Index

Viewing users

Each user account has its own user details page which is accessible to anyone. There is currently no facility for listing all users in the database. List of users that have a role on a given site appears on site details pages (see section about sites). It is also possible to search for a user's account using the search feature on the side menu.

Viewing sites

A site listing page shows a listing of all the sites in the database, with controls to page through the listing. The table headers can be clicked to set the ordering (ascending or descending).

Each site also has its own listing page. By clicking the link to view a site, you can see all of the site's information

  • Site listing page is available from the side menu in GOCDB4 by clicking on the Browse Sites link.
  • sites belonging to a given NGI/ROC are also listed from the ROC details pages (see below)

Viewing service endpoints

A service endpoint is a single entity formed by a hostname and a hosted service.

There are different pages in GOCDB4 where service endpoints are listed:

  • A full service endpoints listing page, that shows a listing of all the endpoints in the database, with controls to page through the listing. The table headers can be clicked to set the ordering.
  • Site details page, where all the service endpoints belonging to this site are listed

Each endpoint also has its own listing page. By clicking the link to view a service endpoint, you can see all associated information.

  • Service Endpoints listing page is available from the side menu in GOCDB4 by clicking on the Browse Service Endpoints link.

Viewing downtimes

There are different pages on which downtimes are listed:

  • An "archives" page, linked from the main menu, that allows to search through all downtimes
  • A "recent and planned" page , linked from the main menu, that presents a search tool implemented by the EGI Operations Portal
  • Site details page, where all the downtimes associated to the site are listed
  • Service endpoint details page, where all the downtimes associated to the service endpoint are listed

Each downtime has its own listing page, accessible by clicking on the "view" link in downtime listing pages.

Viewing Groups and Group information

The main page listing groups actually shows NGIs/ROCs, and is available from

  • List of NGIs/ROCs and associated contacts, linked from the main menu

Groups are also listed from site details pages (all groups the site belongs to). Because groups are generic entities in GOCDB4, there are many logical notions that are presented in this way: NGIs, Countries, Production Infrastructure... pretty much everything that groups sites together is defined as a group.

Each group has its own listing page, accessible by clicking on the "view" link in group listing pages. A group details page shows users with a role on that group, as well as member sites and associated contacts and roles.

Data Visibility

If a site or service endpoint is marked as being visible to EGI then they will be exposed to the central operational tools. For example marking a site as being visible to EGI will mean that it can be monitored and will appear in the central operations portal. Un-ticking this box effectively hides the selected object from EGI. Previous to this feature being released all sites and service endpoints in GOCDB were considered to be visible to EGI.

If a site or service endpoint is not marked as visible to EGI then it won't be exposed to the central operation tools. This can be useful if you wish to hide certain parts of your infrastructure from EGI but still have the information stored and accessed from the same GOCDB instance. Another use for non-EGI sites and service endpoints is to have them monitored by regional versions of the operational tools. For example a service endpoint could be declared in GOCDB as not visible to EGI but monitored by the regional monitoring tools.

Note that exposing a site / service endpoint as EGI does not override the production status or certification status fields. For example if a site isn't marked as production it won't be monitored centrally even if it's marked as visible to EGI.


How to and FAQ

What is so different between GOCDB3 and GOCDB4?

GOCDB3 and GOCDB4 are two animals with a similar shell but very different guts... you might want to browse the GOCDB4 architecture documentation to know more about what makes GOCDB4 special.

Why can't I update information in GOCDB4 visualisation portal?

One of the main features of GOCDB4 is its ability to be distributed to NGIs, while keeping a central view of all EGI data. GOCDB4 visualisation portal, as its name suggests, has been designed as a read-only repository. It gathers and mirrors sets of information maintained and updated elsewhere.

The read/write version of GOCDB4, which will be the base for regional portals, is available at

Why can't there be one single system just like GOCDB3?

NGIs that will install their own regional GOCDB will update information regionally, and this will be reflected centrally on the Visualisation Portal. This is exactly what the current configuration offers: a system to update data that can be split and regionalised (GOCDB4 input system) and a system that will remain central and mirror all data (GOCDB4 visualisation portal). Regionalisation can't happen if we keep one single read/write central system.

How long does it take for recently added/updated data to appear in GOCDB4 visualisation portal?

Data updated in the GOCDB4 Input System will appear in the visualisation portal immediately.

Known Issues

  • Sorting tables by certain fields doesn't work. Although sorting should be possible by any column headers, some of them don't work.
  • Some display problems in Internet Explorer. Some tables don't show up very nicely when using IE.
  • Downtime archives search tool doesn't show downtimes at site level. Only downtimes declared on service endpoints are shown. This is not an issue as such since all downtimes will be declared in GOCDB4 at service level, but this misses some of the information coming from GOCDB3.
