How to add URL service endpoint information into GOC-DB

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.

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

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)
click on the EDIT button on the top-right corner
fill in the Service URL field with the queue URL;
Now the CREAM-CE service endpoint contains the required queue information. Proceed in a similar way for the other CREAM-CE and SRM services.

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.

this is the service summary page. You need to click on the Add endpoint button for registering additional endpoint URLs.
Fill in the proper information and don't forget to select the "Monitored" flag for making nagios to detect the new endpoint.
The summary page of the endpoint just added should look like this one.
And this is the summary page of the service reporting the information about all its endpoints registered: the first one in the Grid Information section and the additional ones in the Service Endpoints section.
