View/edit binary Protocol Buffers messages
message
tasks.proto:152Used in:
bytes raw_histogram = 1
HdrHistogram.rs `Histogram` serialized to binary in the V2 format
uint64 max_value = 2
The histogram's maximum value.
uint64 high_outliers = 3
The number of outliers which have exceeded the histogram's maximum value.
optional uint64 highest_outlier = 4
The highest recorded outlier. This is only present if `high_outliers` is greater than zero.
message
tasks.proto:120Task performance statistics.
Used in:
optional created_at = 1
Timestamp of when the task was spawned.
optional dropped_at = 2
Timestamp of when the task was dropped.
uint64 wakes = 3
The total number of times this task has been woken over its lifetime.
uint64 waker_clones = 4
The total number of times this task's waker has been cloned.
uint64 waker_drops = 5
The total number of times this task's waker has been dropped.
optional last_wake = 6
The timestamp of the most recent time this task has been woken. If this is `None`, the task has not yet been woken.
optional poll_stats = 7
Contains task poll statistics.
uint64 self_wakes = 8
The total number of times this task has woken itself.
optional scheduled_time = 9
The total duration this task was scheduled prior to being polled, summed across all poll cycles. Note that this includes only polls that have started, and does not reflect any scheduled state where the task hasn't yet been polled. Subtracting both `busy_time` (from the task's `PollStats`) and `scheduled_time` from the total lifetime of the task results in the amount of time it spent unable to progress because it was waiting on some resource.
message
tasks.proto:71Data recorded when a new task is spawned.
Used in:
optional id = 1
The task's ID. This uniquely identifies this task across all *currently live* tasks. When the task's stats change, or when the task completes, it will be identified by this ID; if the client requires additional information included in the `Task` message, it should store that data and access it by ID.
optional metadata = 2
The numeric ID of the task's `Metadata`. This identifies the `Metadata` that describes the `tracing` span corresponding to this task. The metadata for this ID will have been sent in a prior `RegisterMetadata` message.
Task.Kind kind = 3
The category of task this task belongs to.
repeated fields = 4
A list of `Field` objects attached to this task.
repeated parents = 5
An ordered list of span IDs corresponding to the `tracing` span context in which this task was spawned. The first span ID in this list is the immediate parent, followed by that span's parent, and so on. The final ID is the root span of the current trace. If this is empty, there were *no* active spans when the task was spawned. These IDs may correspond to `tracing` spans which are *not* tasks, if additional trace data is being collected.
optional location = 6
The location in code where the task was spawned.
The category of task this task belongs to.
Used in:
SPAWN = 0
A task spawned using a runtime's standard asynchronous task spawning operation (such as `tokio::task::spawn`).
BLOCKING = 1
A task spawned via a runtime's blocking task spawning operation (such as `tokio::task::spawn_blocking`).
message
tasks.proto:43A task details update
Used as response type in: instrument.Instrument.WatchTaskDetails
optional task_id = 1
The task's ID which the details belong to.
optional now = 2
The timestamp for when the update to the task took place.
oneof poll_times_histogram
A histogram of task poll durations. This is either: - the raw binary representation of a HdrHistogram.rs `Histogram` serialized to binary in the V2 format (legacy) - a binary histogram plus details on outliers (current)
bytes legacy_histogram = 3
HdrHistogram.rs `Histogram` serialized to binary in the V2 format
histogram = 4
A histogram plus additional data.
optional scheduled_times_histogram = 5
A histogram of task scheduled durations. The scheduled duration is the time a task spends between being woken and when it is next polled.
message
tasks.proto:15A task state update. Each `TaskUpdate` contains any task data that has changed since the last update. This includes: - any new tasks that were spawned since the last update - the current stats for any task whose stats changed since the last update
Used in:
repeated new_tasks = 1
A list of new tasks that were spawned since the last `TaskUpdate` was sent. If this is empty, no new tasks were spawned.
map<uint64, > stats_update = 3
Any task stats that have changed since the last update. This is a map of task IDs (64-bit unsigned integers) to task stats. If a task's ID is not included in this map, then its stats have *not* changed since the last `TaskUpdate` in which they were present. If a task's ID *is* included in this map, the corresponding value represents a complete snapshot of that task's stats at in the current time window.
uint64 dropped_events = 4
A count of how many task events (e.g. polls, spawns, etc) were not recorded because the application's event buffer was at capacity. If everything is working normally, this should be 0. If it is greater than 0, that may indicate that some data is missing from this update, and it may be necessary to increase the number of events buffered by the application to ensure that data loss is avoided. If the application's instrumentation ensures reliable delivery of events, this will always be 0.
