Measure Reference Manual

MISC-CALLS
For OSS, this counter totals operations that increase FILE-BUSY-TIME but are not READS, WRITES,
or INFO-CALLS. APIs that fall in this category are ioctl(), fsync(), ftruncate(), lseek(), and fcntl(), and
the socket APIs connect(), setsockopt(), accept(), and shutdown().
Counter type: Incrementing.
OSS-BLOCK-READ-BYTES
For OSS regular files only, the number of bytes read to cache as a result of OSS-BLOCK-READS.
Counter type: Accumulating.
OSS-BLOCK-READS
For OSS regular files only, the number of block read requests to DP2 issued to fill OSS cache. A
block read call can return more than one block.
Counter type: Incrementing.
OSS-CACHE-READ-BYTES
For OSS regular files only, the number of bytes read by OSS-CACHE-READS.
Counter type: Accumulating.
OSS-CACHE-READS
For OSS regular files only, the number of READS performed using OSS cache.
Counter type: Incrementing.
OSS-CACHE-WRITE-BYTES
For OSS regular files only, the number of bytes written by OSS-CACHE-WRITES.
Counter type: Accumulating.
OSS-CACHE-WRITES
For OSS regular files only, the number of WRITES performed using OSS cache.
Counter type: Incrementing.
OSS-FLOW-CONTROLS
For OSS sockets and pipes, this counter reports the number of times a WRITE operation was
blocked.
Counter type: Incrementing.
READ-BYTES
Number of bytes returned to a user application data buffer. Available for all file open types.
Counter type: Accumulating.
READS
In D-series RVUs, number of calls to file-system read operations such as READX and OSS file system
read APIs such as read() or recv(). For OSS, the total includes OSS-CACHE-READS. For the Enscribe
file system, the total includes non-DBIO and DBIO operations. This counter includes both user and
system calls to these procedures.
In G-series RVUs, number of calls to the READ, READLOCK, READUPDATE, and READUPDATELOCK
procedures. This counter includes both user and system calls to these procedures. In G05 and later
RVUs, this counter includes direct bulk I/O read operations.
Counter type: Incrementing.
