5 LAVDRIVER, SYSTEM_MGMT,  Load-Averaging Device Driver   B     Here is a VMS driver you can load which will keep track of theF load average in a way you can retrieve it. The algorithm used by it is@ not necessarily the same as LAT, but closer to TOPS. To read the@ load average, $ASSIGN or open a channel to the device _LAV0: andC read 36 bytes from it. The first 12 bytes are three "F"-type floats A which are the 1, 5, and 15 minute load averages respectively. The G next 12 bytes are the 1, 5, and 15 minute average blocking priority (if G your process is below the average blocking priority you aren't going to E get much CPU, if above it you will get a lot). The last three are the I 1, 5, and 15 minute averages of the longest I/O queue length on any disk, 8 a decent indication of how backed up your I/O system is.  G                                                         Kenneth Adelman ;                                                         TGV   
