Module perfcnt::linux::perf_format
[−]
[src]
Contains the various data format structures as used by perf
In order to parse these structures from perf files or perf MMAP buffers, please have a look at the functions in parser.rs.
Structs
| BranchEntry | |
| BuildIdRecord | |
| CommRecord | |
| Cpu |
Generic CPU description. Used in many different perf structures. |
| CpuTopology | |
| Event | |
| EventAttr | |
| EventAttrFlags | |

| EventHeader | |
| ExitRecord |
This record indicates a process exit event. |
| ForkRecord |
This record indicates a fork event. |
| GroupDesc | |
| HeaderFlags | |
| LostRecord | |
| MMAP2Record | |
| MMAPRecord |
The MMAP events record the PROT_EXEC mappings so that we can correlate user-space IPs to code. |
| NrCpus | |
| NumaNode | |
| PerfFileHeader | |
| PerfFileSection | |
| PmuMapping | |
| ReadFormat |
We use the same read format for READ_FORMAT_GROUP and non-grouped reads for simplicity |
| ReadFormatFlags | |
| ReadRecord | |
| SampleFormatFlags | |
| SampleId | |
| SampleRecord |
This record indicates a sample. |
| ThreadId |
Unique thread descriptor. Used in many different perf structures. |
| ThrottleRecord | |
| UnthrottleRecord |
Enums
| EventAttrType | |
| EventData | |
| EventType | |
| HeaderFlag |
Constants
| EVENT_ATTR_COMM |
include comm data |
| EVENT_ATTR_DISABLED |

| EVENT_ATTR_EXCLUDE_CALLCHAIN_USER |
exclude user callchains |
| EVENT_ATTR_EXCLUDE_GUEST |
don't count in guest |
| EVENT_ATTR_EXCLUDE_HOST |
don't count in host |
| EVENT_ATTR_EXCLUDE_HV |
ditto hypervisor |
| EVENT_ATTR_EXCLUDE_IDLE |
don't count when idle |
| EVENT_ATTR_EXCLUDE_KERNEL |
ditto kernel |
| EVENT_ATTR_EXCLUDE_USER |
don't count user |
| EVENT_ATTR_EXCLUSIVE |
only group on PMU |
| EVENT_ATTR_FREQ |
use freq, not period |
| EVENT_ATTR_INHERIT |
children inherit it |
| EVENT_ATTR_INHERIT_STAT |
per task counts |
| EVENT_ATTR_MMAP |
include mmap data |
| EVENT_ATTR_MMAP2 |
include mmap with inode data |
| EVENT_ATTR_MMAP_DATA |
non-exec mmap data |
| EVENT_ATTR_PINNED |
must always be on PMU |
| EVENT_ATTR_SAMPLE_ID_ALL |
sample_type all events |
| EVENT_ATTR_SAMPLE_IP_ARBITRARY_SKID |
SAMPLE_IP can have arbitrary skid |
| EVENT_ATTR_SAMPLE_IP_CONSTANT_SKID |
SAMPLE_IP must have constant skid |
| EVENT_ATTR_SAMPLE_IP_REQ_ZERO_SKID |
SAMPLE_IP requested to have 0 skid |
| EVENT_ATTR_SAMPLE_IP_ZERO_SKID |
SAMPLE_IP must have 0 skid |
| EVENT_ATTR_TASK |
trace fork/exit |
| EVENT_ATTR_WATERMARK |
wakeup_watermark |
| FORMAT_GROUP |
Allows all counter values in an event group to be read with one read. |
| FORMAT_ID |
Adds a 64-bit unique value that corresponds to the event group. |
| FORMAT_TOTAL_TIME_ENABLED |
Adds the 64-bit time_enabled field. This can be used to calculate estimated totals if the PMU is overcommitted and multiplexing is happening. |
| FORMAT_TOTAL_TIME_RUNNING |
Adds the 64-bit time_running field. This can be used to calculate estimated totals if the PMU is overcommitted and multiplexing is happening. |
| PERF_SAMPLE_ADDR |
Records an address, if applicable. |
| PERF_SAMPLE_BRANCH_STACK |
This provides a record of recent branches, as provided by CPU branch sampling hardware (such as Intel Last Branch Record). Not all hardware supports this feature. See the branch_sample_type field for how to filter which branches are reported. |
| PERF_SAMPLE_CALLCHAIN |
Records the callchain (stack backtrace). |
| PERF_SAMPLE_CPU |
Records CPU number. |
| PERF_SAMPLE_DATA_SRC |
Records the data source: where in the memory hierarchy the data associated with the sampled instruction came from. This is only available if the underlying hardware supports this feature. |
| PERF_SAMPLE_ID |
Records a unique ID for the opened event's group leader. |
| PERF_SAMPLE_IDENTIFIER | |
| PERF_SAMPLE_IP |
Records instruction pointer. |
| PERF_SAMPLE_PERIOD |
Records the current sampling period. |
| PERF_SAMPLE_RAW |
Records additional data, if applicable. Usually returned by tracepoint events. |
| PERF_SAMPLE_READ |
Record counter values for all events in a group, not just the group leader. |
| PERF_SAMPLE_REGS_INTR | |
| PERF_SAMPLE_REGS_USER |
Records the current user-level CPU register state (the values in the process before the kernel was called). |
| PERF_SAMPLE_STACK_USER |
Records the user level stack, allowing stack unwinding. |
| PERF_SAMPLE_STREAM_ID |
Records a unique ID for the opened event. Unlike PERF_SAMPLE_ID the actual ID is returned, not the group leader. This ID is the same as the one returned by PERF_FORMAT_ID. |
| PERF_SAMPLE_TID |
Records the process and thread IDs. |
| PERF_SAMPLE_TIME |
Records a timestamp. |
| PERF_SAMPLE_TRANSACTION | |
| PERF_SAMPLE_WEIGHT |
Records a hardware provided weight value that expresses how costly the sampled event was. This allows the hardware to highlight expensive events in a profile. |
