Information System
LCG Infosites ToolThe lcg-infosites command can be used as an easy way to retrieve information on Grid resources for the most common use cases.
USAGE: lcg-infosites --vo <vo_name> options -v <verbose_level> --is <BDII_to_query>
Description of the Attributes:
vo : The name of the user vo (mandatory)
options : The tool admits the following options:
- ce :
- The information related to number of CPUs, running jobs,
waiting jobs and names of the CEs are provided.
All these data group all VOs together.-
-v 1 only the names of the queues will be printed.
-
-v 2 The RAM Memory together with the operating system and its version
and the processor included
in each CE are printed.
- se :
- The names of the SEs supported by the user's VO together
with the kind of Storage System, the used and
available space will be printed.-
-v 1 only the names of the SEs will be printed.
- closeSE :
- The names of the CEs where the user's VO is allowed to run
together with their corresponding
closest SEs are provided.
- lrc (rmc) :
- The name of the lrc (rmc) corresponding to the user's VO
- lfc :
- The name of the machine hosting the LFC catalog is printed.
- tag :
- The names of the tags relative to the software installed in site is printed together with the corresponding CE.
- all :
- It groups together the information provided by ce, se, lrc and rmc.
- is :
- If not specified the BDII defined in default by the
variable LCG_GFAL_INFOSYS will be queries.
However the user may want to query any other BDII without redefining this environment variable.
This is possible specifying this argument followed by the name of the BDII which the user wants to query.
All options admits this argument.

The lcg-info command can be used to list either CEs or the SEs
that satisfy a given set of conditions on their attributes,
and to print, for each of them, the values of a given set of
attributes.
The information is taken from the BDII specified by the
$LCG_GFAL_INFOSYS environment variable or in the command line.
The general format of the command for listing CEs or SEs information
is:
$ lcg-info [--list-ce | --list-se] [--query <some_query>] [--attrs <some_attrs>]
where
-
-list-ce or -list-se must be used to indicate if CEs or SEs should be
listed;
-
the -query option introduces a filter (conditions to be accomplished)
to the elements of the list;
-
the -attrs option may be used to specify which attributes to print.
-
If -list-ce is specified, then only CE attributes are considered
(others are just ignored), and the reverse is true for -list-se. The
attributes supported (which may be included with -attrs or within the
-query expression) are only a subset of the attributes present in the
GLUE schema, those that are most relevant for a user.
-
The -vo option can be used to restrict the query to CEs and SEs which
support the given VO; it is mandatory when querying for attributes
which are inherently referred to a VO, like AvailableSpace and
UsedSpace.
-
Apart from the listing options, the -help option can be specified
(alone) to obtain a detailed description of the command, and the
-list-attrs option can be used to get a list of the supported
attributes.
Exercise 5: Get the list of supported attributes:
$ lcg-info --list-attrs

[...]
