= 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.
'''Important: currently these steps are required only for the sites under certification. For sites in production, EGI Monitoring is retrieving from the Top-BDII these information'''
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. '''').
*SRM: the value of the attribute GlueServiceEndpoint published in the BDII (e.g. ''httpg://'')
*Other service types: the value of the attribute GlueServiceEndpoint published in the BDII
It is also possible registering additional endpoints for each service: by setting also the "Monitored" flag, ARGO will monitor them.
For having more information about managing the Service endpoints in GOC-DB, please consult the relative [ documentation].
== 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
For example:
$ export
$ lcg-infosites --vo ops ce | grep nikhef
  5680      15          0            0      0
  5680      17          1            1      0
  5680      15          0            0      0
  5680      15          0            0      0
  5680      16          0            0      0
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:// -b "mds-vo-name=NCG-INGRID-PT,o=grid" '(&(objectClass=GlueService)(GlueServiceType=SRM))' GlueServiceEndpoint
dn: GlueServiceUniqueID=httpg://,Mds-Vo-name=NCG-INGRID-PT,o=grid
GlueServiceEndpoint: '''httpg://'''
In a similar way, by just changing the value of ''GlueServiceType'', you can get the endpoint URLs of other services.
An alternative way for retrieving the GlueServiceEndpoint URL is using the GLUE2 information browser provided by VAPOR ( select your NGI, then your site and hence the Storage service; click on the ''endpoint details'' button for finding the URL associated to the SRM interface.
== 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]]
| 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.
| [[File:Picture08.png|frameless|border|800px]]
== Examples ==
=== webdav ===
In order to properly monitor your webdav endpoint:
*you should register a new service endpoint with the webdav service type, separated from the SRM one;
*fill in the webdav URL containing also the VO ops folder, for example: or
**it corresponds to the value of GLUE2 attribute GLUE2EndpointURL (containing the used port and without the VO folder);
*verify that the webdav url (for example: ) is properly accessible.
=== GridFTP ===
In order to properly monitor your gridftp endpoint for ops VO
*register a new service endpoint, associating the storage element hostname to the service type “globus-GRIDFTP”, with the "production" flag disabled;
*in the “Extension Properties” section of the service endpoint page, fill in the following fields:
**Name: SE_PATH
**Value: /dpm/  (this is an example, set the proper path)
*check if the tests are ok (it might take some hours for detecting the new service endpoint) and then switch the production flag to "yes"
=== SURL value for SRM ===
The SURL value needed by the SRM monitoring probes is the following structure:
srm://<hostname>:<port>/srm/managerv2?SFN=<GlueSAPath or GlueVOInfoPath>
For example:
* As explained in previous sections, you can retrieve the port number from the ''GlueServiceEndpoint'' information.
* If your SE provides ''GlueSAPath'' information, use that. To retrieve it:
$ ldapsearch -x -LLL -H ldap:// -b "mds-vo-name=NCG-INGRID-PT,o=grid" '(&(objectClass=GlueSA)(GlueSAAccessControlBaseRule=VO:ops))' GlueSAPath GlueChunkKey
dn: GlueSALocalID=opsdisk:replica:online,,Mds-Vo-name=NCG-INGRID-PT,o=grid
GlueSAPath: /gstore/t2others/ops
* if your SE doesn't provide ''GlueSAPath'' information, use instead the ''GlueVOInfoPath'' one:
$ ldapsearch -x -LLL -H ldap:// -b "Mds-Vo-name=TW-NTU-HEP,o=grid" '(&(objectClass=GlueVOInfo)(GlueVOInfoAccessControlBaseRule=VO:ops))' GlueVOInfoPath GlueVOInfoLocalID GlueChunkKey
dn: GlueVOInfoLocalID=ops:SRR,GlueSALocalID=SRR:SR:replica:*****,,Mds-Vo-name=TW-NTU-HEP,o=grid
GlueVOInfoPath: /dpm/
GlueChunkKey: GlueSALocalID=SRR:SR:replica:*****
GlueVOInfoLocalID: ops:SRR
dn: GlueVOInfoLocalID=ops:data01,GlueSALocalID=data01:replica:online,,Mds-Vo-name=TW-NTU-HEP,o=grid
GlueVOInfoPath: /dpm/
GlueChunkKey: GlueSALocalID=data01:replica:online
GlueVOInfoLocalID: ops:data01
*On GOCDB, in the “Extension Properties” section of the service endpoint page, fill in the following fields:
**Name: SURL
**Value: the actual SURL value, for example: srm://
