Monitoring information logged per file access

For each call to FMOPEN, an update is sent to the FATMEN server to update the last access date and time, use count etc. as described above. This logging record also records additional information, which is stored in the logs of the servers.

This information consists of the following quantities:

CHFNFA

The fully qualified name of the actual file that was accessed.

IHOWFA

A bit pattern indicating how the file was accessed.

JLOCFA=1

Local disk (standard file system)

JSFSFA=2

VM shared file system

JMSCFA=3

MSCP (VAXcluster)

JAFSFA=4

Andrew file system

JOSFFA=5

OSF distributed file system

JDFSFA=6

DEC DFS

JNFSFA=7

Sun NFS

JDECFA=8

DECnet

JCSPFA=9

CSPACK server

JFPKFA=10

FPACK server

JRFIFA=11

RFIO

JSTGFA=31

Stage required

JTPMFA=32

TPMNT (=not staged)

ITIMFA

The time in seconds spent in the routine FMOPEN (including the time for STAGE operations etc.)

In addition, the username and nodename from which the file was accessed is logged, together with the generic name and FATMEN keys (location code, media type and data representation). These permit further information to be extracted from the FATMEN catalogue if required.
