The raw information about all dCache activities can be found in
/var/lib/dcache/billing/<YYYY>/<MM>/billing-<YYYY.MM.DD>.
A typical line looks like
Example:
05.31 22:35:16 [pool:<pool-name>:transfer] [000100000000000000001320,24675] myStore:STRING@osm 24675 474 true {GFtp-1.0 <client-host-fqn> 37592} {0:""}
The first bracket contains the pool name, the second the
pnfs ID and the size
of the file which is transferred. Then follows the storage class, the actual
amount of bytes transferred, and the number of milliseconds the
transfer took. The next entry is true if the
transfer was a wrote data to the pool. The first braces contain
the protocol, client FQN, and the client host data transfer listen
port. The final bracket contains the return status and a possible
error message.
The dCache web interface (described in the section called “The Web Interface for Monitoring dCache”) contains under the menu point
“Actions Log” summary information extracted from
the information in the billing-directory.
The accounting information can also be redirected into a
database.
