Review of the OSG Critical Probes used for Availability Metrics Calculations
OSG Services
The only authoritative source of information for SAM in terms of OSG services for OPS vo is the OSG interoperability monitoring list, which is accessible through this URL:
http://oim.grid.iu.edu/publisher/get_osg_interop_monitoring_list.php
This means that SAM will ONLY monitor those services under OPS credentials.
At present time, the service names that SAM expects to find in that URL are the ones listed in the first column of this table:
List of OSG probes
The OSG probes available in the RSV (Resource & Service Validation) project are listed here:

Equivalence between EGEE and OSG critical tests
Computing Element (CE):
-
CE-sft-caver
is equivalent to org.osg.certificates.cacert-expiry
-
CE-sft-csh
is equivalent to ==
-
CE-sft-lcg-rm
is equivalent to ==
-
CE-sft-job
is included in ==
-
CE-sft-softver
is equivalent to org.osg.general.osg-version.txt
-
CE-host-cert-valid
This one does not apply for OSG (no way to check)
-
CE-sft-brokerinfo
This one does not apply for OSG (no broker)
- This is not available in EGEE; in OSG org.osg.general.ping-host.txt
- This is not available in EGEE; in OSG org.osg.globus.gram-authentication
Storage Element (SE):
- These do not apply to OSG as they only have SRMs
-
SE-lcg-cr
-
SE-lcg-cp
-
SE-lcg-del
SRM (SRM):
Site BDII (sBDII):
- Does not apply as OSG only uses a global BDII. A future release of RSV will include Global BDII tests.
-
sBDII-sanity
-
sBDII-performance
Current Critical Tests for OSG defined in SAM (These will be critical through at least June 30, 2008)
-
org.osg.certificates.crl-expiry
- org.osg.certificates.crl-expiry
: Checks for expired and expiring-soon CAcerts/CRLs on remote host. Stages worker script defined in OSG_RSV_Probe_Base (or as provided using commandline argument) to remote host; and then checks the *.0 or .r0 files in $OSG_LOCATION/globus/share/certificates/ depending on -m value.
-
org.osg.general.osg-directories-CE-permissions
-
org.osg.general.osg-version
-
org.osg.globus.gridftp-simple
(remove for proposed status, will be critical for resources with service type OSGGdFTP
)
- org.osg.globus.gridftp-simple
: Checks if OSG-GridFtp
works to and from remote host. A test file is gridftp'ed to remote host, and back. Then the files are checked for consistency.
