Introduction

In this page you can find the control plots for the T0.

T0 transfers

EOS->Castor transfers. These plots show the time needed for a file to be transferred to the disk cache in Castor in the last hours. This time sholud be low (less than a couple of hours).
  • The script runs every 4 hours in the machine aiatlas114. You can found the less recent plots in the folder http://adc-mon.cern.ch/T0_Transfers_Timing/latest/ .
  • The informations are taken with DB queries (activity: T0 Tape). The trasfer time is the time from the creation of the rule in Rucio to his update.
  • There are more detailed plots, specifying the time before FTS starts to transfer, the actual FTS trasnfer and the finisher queue time.
  • The detailed informations (created_at, updated_at, dest_url, name, scope, state, submitted_at, transferred_at) are stored in CSV files located in the same folder, but every two weeks those files are deleted. Plots still remain in the "older" folder.
  • A not present plot indicate that no data are available for that time.

T0 -> T1s transfers

Here you can see the time needed to export a file from the T0 to the T1s for the last 48 hours. This should be less then 5-6 hours. The same feature of the "T0 transfers" section are valid here (activity: T0 export).
  • If you see a slow transfer speed ....

DAOD creation times (work in progress)

[http://adc-mon.cern.ch/T0_Transfers_Timing/prova/DAOD/boh4.jpg][Here]] is plot the time needed for the creation of the DAODs as difference from the last file updated on the DAOD datasets to the creation time of the RAW transfer rule.
  • The run number, the total DAOD for that run and the completed DAOD are also shown.
  • Only runs where "merged" data are available are plot.
