Structs

All

ComponentSelector

Specifies a pattern of component monikers which identify components being selected for.

Interest

Interest expresses the scope of clients’ desired diagnostics data, e.g. for filtering messages or controlling their generation.

LogInterestSelector

LogSettingsSetComponentInterestRequest

LogSettingsSetInterestRequest

LogStreamOptions

PerformanceConfiguration

Parameters which configure a diagnostics stream’s performance properties.

PropertySelector

A selector defining a set of nodes to match, and on those matched nodes a set of named properties to match.

SampleDatum

SampleParameters

The data for one Sample server.

Selector

Structured selector containing all required information for pattern-matching onto string-named properties owned by nodes in a data hierarchy, where data hierarchies belong to specific components.

StreamParameters

Parameters needed to configure a stream of diagnostics information.

SubtreeSelector

A selector defining a set of nodes to match, for which the entire subtree including those nodes are selected.

Enums

ClientSelectorConfiguration

ConfigurationError

ConfigurationError indicates a bad setting in Sample::Set. This value is returned before the first sample is taken.

DataType

Format

Enum used to specify the output format for Reader results.

ReaderError

Enum describing the potential failure states of the streaming protocol when serving results to the client over the result iterator.

RuntimeError

RuntimeError indicates errors that manifest after the Sample server has begun periodically sampling data. Clients can ignore these errors, though they could potentially indicate that no SampleReady request will ever arrive, or that the batch iterator might behave in unexpected ways, such as hanging.

SampleStrategy

SampleStrategy instructs Archivist on the circumstances under which you want to receive data for the given SampleDatum.

SelectorArgument

Argument used for Archive selectors, can be either the pre-parsed fidl struct or string representation.

Severity

The severity of a given record.

StreamMode

Enum specifying the modes by which a user can connect to and stream diagnostics metrics.

StringSelector

StringSelector is an union defining different ways to describe a pattern to match strings against.

TreeNames

TreeNames are the set of names of fuchsia.inspect.Trees for a component that were parsed out of a selector. The hierarchy and property selector portions will only be applied to trees that match this set.

TreeSelector

TreeSelector represents a selection request on a hierarchy of named nodes, with named properties on those nodes.

Constants

COMPONENT_URL_ARG_NAME

MAXIMUM_ENTRIES_PER_BATCH

The size 64 was chosen because entries in batches are handles to VMOs and there is a limit of 64 handles per fidl message.

MAXIMUM_RAW_SELECTOR_LENGTH

The size bound of 1024 is a reasonably low size restriction that meets most canonical selectors we’ve ecountered.

MAX_DATA_HIERARCHY_DEPTH

MAX_LOG_SELECTORS

Max number of LogInterestSelectors that can be specified via a listener.

MAX_MONIKER_SEGMENTS

MAX_SAMPLE_PARAMETERS_PER_SET

The maximum number of parameters that can be sent in one Set call.

MAX_STRING_SELECTOR_LENGTH

MONIKER_ARG_NAME

ROLLED_OUT_ARG_NAME
