= How to add URL service endpoint information into GOC-DB =
{{Template:Op menubar}} {{Template:Doc_menubar}}


For monitoring purposes, each service endpoints registered into GOC-DB with the flags ''production'' and ''monitored''  should include the endpoint URL information in order to be contacted by the relative nagios probe.
{{DeprecatedAndMovedTo|new_location=https://docs.egi.eu/internal/configuration-database/adding-service-endpoint/}}
 
The information needed for service type are:
*CREAM-CE: the queue URL where the ops VO is enabled. This is the value of the attribute GlueCEUniqueID published in the BDII (e.g. ''cream.egi.eu:8443/cream-pbs-ops'').
*SRM: the value of the attribute GlueServiceEndpoint published in the BDII (e.g. ''httpg://se.egi.eu:8444/srm/managerv2'')
*Other service types: the value of the attribute GlueServiceEndpoint published in the BDII
 
 
== Get the information ==
 
For retrieving the queue URL from the BDII, you can simply use the command ''lcg-infosites'' executed from an UI. Be sure to query a production Top-BDII: you can either set the one provided by your Operations Centre or choose one from https://goc.egi.eu/portal/index.php?Page_Type=Service_Group&id=1205
 
For example:
$ export LCG_GFAL_INFOSYS=egee-bdii.cnaf.infn.it:2170
$ lcg-infosites --vo ops ce | grep nikhef
  5680      15          0            0      0 dissel.nikhef.nl:2119/jobmanager-pbs-infra
  5680      17          1            1      0 gazon.nikhef.nl:8443/cream-pbs-infra
  5680      15          0            0      0 juk.nikhef.nl:8443/cream-pbs-infra
  5680      15          0            0      0 klomp.nikhef.nl:8443/cream-pbs-infra
  5680      16          0            0      0 stremsel.nikhef.nl:8443/cream-pbs-infra
 
For getting the GlueServiceEndpoint URL of your SRM service, you can launch a ldap query to your site-bdii (or also directly to the SRM service):
 
$ ldapsearch -x -LLL -H ldap://sbdii01.ncg.ingrid.pt:2170 -b "mds-vo-name=NCG-INGRID-PT,o=grid" '(&(objectClass=GlueService)(GlueServiceType=SRM))' GlueServiceEndpoint
dn: GlueServiceUniqueID=httpg://srm01.ncg.ingrid.pt:8444/srm/managerv2,Mds-Vo-name=NCG-INGRID-PT,o=grid
GlueServiceEndpoint: httpg://srm01.ncg.ingrid.pt:8444/srm/managerv2
 
In a similar way, by just changing the value of ''GlueServiceType'', you can get the endpoint URLs of other services.
 
== Fill in the information ==
 
=== URLs information are completely missing ===
 
* URLs information are completely missing: you need to edit the services information
 
{| class="wikitable"
| this is the home page regarding your site. You need to fill in the URL information. Click on a service for displaying its page (e.g. the CREAM-CE)
| [[File:Picture01.png|frameless|border|800px]]
|-
| click on the EDIT button on the top-right corner
| [[File:Picture02.png|frameless|border|800px]]
|-
| fill in the ''Service URL'' field with the queue URL;
| [[File:Picture03.png|frameless|border|800px]]
|-
| Now the CREAM-CE service endpoint contains the required queue information. Proceed in a similar way for the other CREAM-CE and SRM services.
| [[File:Picture04.png|frameless|border|800px]]
|}
 
=== Additional endpoints information ===
 
In case you need to register an additional endpoint for a service, go on the service summary page and add the proper information. In the example below it is shown the case of a computing element.
 
{| class="wikitable"
| this is the service summary page. You need to click on the ''Add endpoint'' button for registering additional endpoint URLs.
| [[File:Picture05.png|frameless|border|800px]]
|-
| Fill in the proper information and don't forget to select the "Monitored" flag for making nagios to detect the new endpoint.
| [[File:Picture06.png|frameless|border|800px]]
|-
| The summary page of the endpoint just added should look like this one.
| [[File:Picture07.png|frameless|border|800px]]
|-
| Now the CREAM-CE service endpoint contains the required queue information. Proceed in a similar way for the other CREAM-CE and SRM services.
| [[File:Picture08.png|frameless|border|800px]]
