Reports on the use of z/OS UNIX by z/OS UNIX processes.
Offsets | Name | Length | Format | Description | |
---|---|---|---|---|---|
0 | 0 | SMF30OPI | 4 | binary | z/OS UNIX process ID. |
4 | 4 | SMF30OPG | 4 | binary | z/OS UNIX process group ID. |
8 | 8 | SMF30OUI | 4 | binary | z/OS UNIX process user ID. |
12 | C | SMF30OUG | 4 | binary | z/OS UNIX process user group ID. |
16 | 10 | SMF30OSI | 4 | binary | z/OS UNIX process session ID. |
20 | 14 | SMF30OSC | 4 | binary | Number of z/OS UNIX services requested by the process. When the z/OS UNIX parmlib option SYSCALL_COUNTS is set to NO, there is no collection of data for the count of syscalls. When gathering syscall counts for a job, do not switch between SYSCALL_COUNTS=YES and SYSCALL_COUNTS=NO because doing so can lead to inaccurate values in the SMF30OSC field. |
24 | 18 | SMF30OST | 4 | binary | Total CPU time (in hundredths of a second) accumulated by z/OS UNIX services requested by the process. Note that the value in SMF30OST is already included in fields SMF30CPT or SMF30CPS. When the z/OS UNIX parmlib option SYSCALL_COUNTS is set to NO, there is no collection of data for CPU usage. When gathering CPU usage for a job, do not switch between SYSCALL_COUNTS=YES and SYSCALL_COUNTS=NO because doing so can lead to inaccurate values in the SMF30OST field. |
28 | 1C | SMF30ODR | 4 | binary | Number of z/OS UNIX directory reads for the process. |
32 | 20 | SMF30OFR | 4 | binary | Read I/O block count for z/OS UNIX regular files. |
36 | 24 | SMF30OFW | 4 | binary | Write I/O block count for z/OS UNIX regular files. |
40 | 28 | SMF30OPR | 4 | binary | Read I/O block count for z/OS UNIX pipes and AF_UNIX sockets. |
44 | 2C | SMF30OPW | 4 | binary | Write I/O block count for z/OS UNIX pipes and AF_UNIX sockets. |
48 | 30 | SMF30OSR | 4 | binary | Reserved. |
52 | 34 | SMF30OSW | 4 | binary | Reserved. |
56 | 38 | SMF30OLL | 4 | binary | Number of pathname lookup calls to the logical file system. |
60 | 3C | SMF30OLP | 4 | binary | Number of pathname lookup calls to the physical file system. |
64 | 40 | SMF30OGL | 4 | binary | Number of pathname generation calls to the logical file system. |
68 | 44 | SMF30OGP | 4 | binary | Number of pathname generation calls to the physical file system to determine a pathname. |
72 | 48 | SMF30OPP | 4 | binary | Parent process ID. |
76 | 4C | SMF30OKR | 4 | binary | Reserved. |
80 | 50 | SMF30OKW | 4 | binary | Reserved. |
84 | 54 | SMF30OMS | 4 | binary | Reserved. |
88 | 58 | SMF30OMR | 4 | binary | Reserved. |
92 | 5C | SMF30OSY | 4 | binary | Number of times the sync() function was called. |
