Plan for ARC Testing set up in Nagios 15.9.11

1. Customize the file /etc/grid-monitoring/org.ndgf.conf with the NGI services.
2. NorduGrid Logging Improvement:
   1. Edit the xrls templates files (in /usr/share/grid-monitoring/org.ndgf/<SERVICE>/xrsl) for all the services and add (gmlog = "gmlog") to them e.g.

more /usr/share/grid-monitoring/org.ndgf/lfc/xrsl

(executable = "testjob.sh")
(jobname = "lfc")
(stdout = "testjob.out")
(gmlog = "gmlog")
(stderr = "testjob.err")
(inputfiles = ("testjob.sh" "/usr/share/grid-monitoring/org.ndgf/lfc/testjob.sh")
              ("file" "%LFC_TESTFILE%"))
(outputfiles = ("testjob.out" "")("testjob.err" "")
               ("outfile" "%LFC_STORAGE_W%/%HOST%-lfc-%TIME%"))
(walltime = "15 min")
(memory = "256")</nowiki>

This will ensure that in case of error the gmlog (useful for debugging) is sent back as part of the outputsandbox. Files in /usr/share/grid-monitoring/org.ndgf : gridftp/xrsl, jobsubmit/xrsl, lfc/xrsl, rls/xrsl, srm/xrsl

3. Data management requirements for NorduGrid: the testfile used for the LFC/SRM/GridFTP tests must be created/managed manually.

It is important that the file/LFC entry be created with the same credentials used by the Nagios monitoring node! A robot certificate will be used in the near future: checks to be carried out with it and the dCache and LFC nodes used by NGI_DE. For the time being, for the ARC tests in the test system (this only affects NGI_CH!), feronia.switch.ch (DPM) and lodur.switch.ch (LFC) are used instead.

Status 21.9.2011

Working on rocmon-fzk.gridka.de, File /etc/grid-monitoring/org.ndgf.conf Dmitry will provide LFC and SRM services to be used by the probes. ops should be working there. See Skype chat for details.
