Login as root and create a regular user account on host *mon-lcg.projects.cscs.ch* 1. Login as user and put a valid certificate in your home dir. <br> If creating on a machine anew start with a grid-cert-request command and follow all the instructions<br> If bringing a certificate (usercert.pem and userkey.pem files) from another machine:<br> <font color=0000aa>% mkdir .globus<br> % chmod g-w .globus<br> % cp userkey.pem usercert.pem .globus/<br> % chmod 600 .globus/userkey.pem<br></font> 1. Collect certificate information<br> <font color=0000aa>% grid-cert-info -subject<br> % grid-cert-info -issuer</font> 1. Send the output from above commands to the person who deals with registering users on a remote machine. For Phoenix cluster info the points of contact are Kerstin Voss kerstinv@upb.de and Georg Birkenheuer birke@upb.de. After the confirmation that the user is added o the grid-map file can collect and transmit the data. Executiion steps: 1. Initialize certificate proxy<br> <font color=0000aa>% grid-proxy-init</font> 1. Run script to collect the data.<br> <font color=0000aa>% ./GetDump</font> 1. Transfer the resulting YYYYMMDD-HHmm.tar.gz file to the remote machine<br> <font color=0000aa>% globus-url-copy file:///home/nadya/20070213-1108.tar.gz gsiftp://arminius-grid.uni-paderborn.de/tmp/20070213-1108.tar.gz</font> 1. send email notification to the points of contact listed above. Specify the file name and any other info if needed. Script [[%ATTACHURL%/GetDumps][GetDumps]] provides for collection of the ganglia records. The script assumes the following (all can be changed): * it is run on the host *mon-lcg.projects.cscs.ch* where ganglia records are stored * ganglia's DB location is */var/lib/ganglia/rrds/*. Two current subdirectories that hold records for the nodes are *PHOENIX-services/* and *PHOENIX-workers/* * repeated running of the script will create another gzipped tar file with dumps inside. -- Main.NadyaWilliams - 13 Feb 2007
