LHCb specific probes in the CERN/IT SAM/Nagios framework

This twiki provides a description of probes used in SAM/Nagios and were speficially developed for LHCb. Descriptions of the general "emi" probes can be found at the SAM description page

LFC probes

These probes are testing basic functionality of the CERN instance of the LHC File Catalog (LFC). You may also have a look at the source code of these probes.

Probe Name Description
org.lhcb.LFC-AllLHCb parent probe for all probes in this section below
org.lhcb.LFC-Ping execute lfc.lfc_ping on the host
org.lhcb.LFC-Read try to read the top level directory of the LFC (/grid/lhcb.cern.ch)
org.lhcb.LFC-Readdir measure time how long it takes to read the top level directory (/grid)
org.lhcb.LFC-Replicate create a file in the read-write instance and check its replicated correctly to the read-only instance within a time limit

SRM probes

Probes testing the SRM protocol (source code)

Probe Name Description
org.lhcb.SRM-AllLHCb parent probe for all probes in the section below
org.lhcb.SRM-GetLHCbInfo retrieve the storage endpoint information for all sites from an afs hosted file
org.lhcb.SRM-VOLsDir list the toplevel SRM space area with gfal_ls
org.lhcb.SRM-VOPut copy a local file via SRM into the VO space area with (lcg_cp3)
org.lhcb.SRM-VOLs list previously copied files in SRM using gfal_ls
org.lhcb.SRM-VOGet retrieve transport URL for previously copied file (lcg_gt3)
org.lhcb.SRM-VODel delete a given file from SRM and return OK if successful (lcg_del4)

WN probes

Probes executed on the worker nodes testing different services and functionalities (source code)

Probe Name Description
org.lhcb.WN-cvmfs test CVMFS client on the worker node, sanity of mount point, VO_LHCB_SW_DIR pointing to mount point, failure reports, connectivity to stratum1(s) via squid(s)
org.lhcb.WN-sft-csh try to execute a simple csh script (dumps environment to a file)
org.lhcb.WN-sft-brokerinfo check if brokerinfo works, try to get the CE name using the tool
org.lhcb.WN-sft-lcg-rm-gfal Check if $LCG_GFAL_INFOSYS variable is set.
org.lhcb.WN-sft-vo-swdir check if VO_LHCB_SW_DIR is defined and list 2 directories in there (non recursive)
org.lhcb.WN-sft-voms check if "voms-proxy-info -all" works
