Fields

quirks: Vec<i32>

scan_all_processes_on_start: Option<bool>

If enabled all processes will be scanned and dumped when the trace starts.

record_thread_names: Option<bool>

If enabled thread names are also recoded (this is redundant if sched_switch is enabled).

proc_stats_poll_ms: Option<u32>

If > 0 samples counters (see process_stats.proto) from /proc/pid/status and oom_score_adj every X ms. It will also sample /proc/pid/smaps_rollup if scan_smaps_rollup = true. This is required to be > 100ms to avoid excessive CPU usage. TODO(primiano): add CPU cost for change this value.

proc_stats_cache_ttl_ms: Option<u32>

This is required to be either = 0 or a multiple of |proc_stats_poll_ms| (default: |proc_stats_poll_ms|). If = 0, will be set to |proc_stats_poll_ms|. Non-multiples will be rounded down to the nearest multiple.

resolve_process_fds: Option<bool>

If true this will resolve filedescriptors for each process so these can be mapped to their actual device or file. Requires raw_syscalls/sys_exit ftrace events to be enabled or new fds opened after initially scanning a process will not be recognized.

scan_smaps_rollup: Option<bool>

If enabled memory stats from /proc/pid/smaps_rollup will be included in process stats.

Implementations

impl ProcessStatsConfig

pub fn quirks( &self, ) -> FilterMap<Cloned<Iter<'_, i32>>, fn(i32) -> Option<Quirks>>

Returns an iterator which yields the valid enum values contained in quirks.

pub fn push_quirks(&mut self, value: Quirks)

Appends the provided enum value to quirks.

pub fn scan_all_processes_on_start(&self) -> bool

Returns the value of scan_all_processes_on_start, or the default value if scan_all_processes_on_start is unset.

pub fn record_thread_names(&self) -> bool

Returns the value of record_thread_names, or the default value if record_thread_names is unset.

pub fn proc_stats_poll_ms(&self) -> u32

Returns the value of proc_stats_poll_ms, or the default value if proc_stats_poll_ms is unset.

pub fn proc_stats_cache_ttl_ms(&self) -> u32

Returns the value of proc_stats_cache_ttl_ms, or the default value if proc_stats_cache_ttl_ms is unset.

pub fn resolve_process_fds(&self) -> bool

Returns the value of resolve_process_fds, or the default value if resolve_process_fds is unset.

pub fn scan_smaps_rollup(&self) -> bool

Returns the value of scan_smaps_rollup, or the default value if scan_smaps_rollup is unset.

Trait Implementations

impl Clone for ProcessStatsConfig

fn clone(&self) -> ProcessStatsConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProcessStatsConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ProcessStatsConfig

fn default() -> Self

Returns the “default value” for a type.

impl Message for ProcessStatsConfig

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

impl PartialEq for ProcessStatsConfig

fn eq(&self, other: &ProcessStatsConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
