Querying the Information System
• In order to query directly the IS elements two high level tools are provided:
• These tools should be enough for most common user needs and can be used to hide the complexity of raw LDAP queries.
lcg-infosites
lcg-info

lcg-infosites
This tool provides information related to Grid services:
lcg-infosites --vo <your_vo> option –-is <your_bdii>
• It’s mandatory to include the vo and the option• The --is option specifies the BDII you want to query If not supplied, the BDII defined into the environment variable LCG_GFAL_INFOSYS will be used
4
lcg-infosites - options
ce Number of CPUs, running and waiting jobs and names of the CEs
se SEs names together with the available and used space
closeSE Names of the CEs where the user’s VO is allowed to run together with their corresponding closest SEs
lfc Name of the lfc Catalog for the user’s VO
tag Name of the tags relative to the software installed in site with the corresponding CE
is Name of the BDII which the user wants query
help Prints all the available options and exit
all It groups all the features just described
5
Initial Step
• Please set the environment variable:
• export LCG_GFAL_INFOSYS=grid004.ct.infn.it:2170

lcg-info
• This tool allows the users to query, in a deeper way, the BDII
• It requires the environment variable LCG_GFAL_INFOSYS to be set to the value of the BDII to be queried e.g. grid004.ct.infn.it:2170
• Prints the list of the CEs or SEs satisfying a given query along with a list of specified attributes.
15
lcg-info
• The query syntax is like this:
attr1 op1 valueN, ... attrN opN valueN where attrN is an attribute name op is =, >= or <=, and the cuts are ANDed A combination of attribute is supported The cuts are comma-separated and spaces
are not allowed
SINCE THE LATEST GLUE-SCHEMA UPDATE ONLY “=“ OPERATOR IS SUPPORTED!
16
lcg-info options
--list-attrs Prints a list of attributes that can be queried.
--list-ce Lists the CEs which satisfy a query, or all the CEs if no query is given.
--list-se Lists the SEs which satisfy a query, or all the SEs if no query is given.
--query Restricts the output to the CEs (SEs) which satisfy the given query.
--bdii Allows to specify a BDII in the form <hostname>:<port>. If not given, the value of the environmental variable LCG_GFAL_INFOSYS is used. If that is not defined, the command returns an error.
--sed Print the output in a "sed-friendly" format.
--attrs Specifies the attributes whose values should be printed.
--vo Restricts the output to CEs or SEs where the given VO is authorized. Mandatory when VO-dependent attributes are queried upon.
