The lscpumf program lists information about CPU-measurement
facilities that are supported by Linux on System z.
- -i, --info
- Displays detailed information about available and supported
CPU-measurement facilities.
- -c,
--list-counters
- Lists counters that are provided by the CPU-measurement facility, omitting
counters for which the LPAR is not authorized. For counter measurements
with the perf program, the raw event identifier is displayed. For Linux
version 5.5 and later, the raw event identifier is displayed as
<type>:<number>, where type is an integer that the kernel
assignes to the CPU Measurement counter facility device driver. For
earlier Linux versions the raw event identifier is displayed as
r<number>.
- -C,
--list-all-counters
- Lists all counters that are provided by the CPU-measurement counter
facility, regardless of LPAR authorization. To list only those counters
for which the LPAR is authorized, use the -c option. For linux version 5.5
and later the raw event identifier is displayed as
<type>:<number>, where type is the number the CPU Measurement
counter facility device driver was assigned to by the kernel. For earlier
linux versions the raw event identifier is displayed as
r<number>.
- -n, --name
- Display the counter name together with the raw event identifier.
- -s,
--list-sampling-events
- Lists perf raw events that activate the sampling facility.
- -h, --help
- Displays help information, then exits.
- -v, --version
- Displays version information, then exits.
