 Split Tornado logs by component
 ===============================
 
-Dirac offers the ability to write logs for each component. One can find logs in <DIRAC FOLDER>/startup/<DIRAC COMPONENT>/log/current

 The idea behind that is to deal with logs independantly from Dirac. It is also possible to grab servers metrics such as cpu, memory and disk usage, giving the opportunity to make correlations between logs and server usage.
