10. Site report HIP / CSC Monitoring:
Accessible with Grid-certificate via: ¤ dCache-pages ¤ srmwatch ¤ ntop
Christof Hanke, HEPIX Spring Meeting 2008, CERN

11. Site report HIP / CSC Monitoring - dCachepages
Christof Hanke, HEPIX Spring Meeting 2008, CERN

12. Site report HIP / CSC Monitoring - srmwatch
search web for :
srmwatch dcache,
not yet fully functional.
Christof Hanke, HEPIX Spring Meeting 2008, CERN

13. Site report HIP / CSC Monitoring - ntop
dCache traffic, here gridftp WAN-ifce pool-node,
still some work to be done here.
Christof Hanke, HEPIX Spring Meeting 2008, CERN

14. Site report HIP / CSC Future plans
¤ attach tape to ALICE pools
¤ work in progress :
¤ srmwatch
¤ ntop/dCache
¤ nagios monitoring
¤ set up workflows for dCache (remove pools, consistency checks, functionality checks)
