executed after the selected metrics and
the metrics output is suppressed.
-D, --httpd Enables the HTTP RPC server.
--http-port PORT Specify what port to run HTTP RPC server.
--stdiod Enables the stdio RPC server.
-i, --interactive Starts interactive mode even after a query
file is specified with -q or
--run-metrics.
-e, --export FILE Export the contents of trace processor
into an SQLite database after running any
metrics or queries specified.
Feature flags:
--full-sort Forces the trace processor into performing
a full sort ignoring any windowing
logic.
--no-ftrace-raw Prevents ingestion of typed ftrace events
into the raw table. This significantly
reduces the memory usage of trace
processor when loading traces containing
ftrace events.
--analyze-trace-proto-content Enables trace proto content analysis in
trace processor.
--crop-track-events Ignores track event outside of the
range of interest in trace processor.
--dev Enables features which are reserved for
local development use only and
*should not* be enabled on production
builds. The features behind this flag can
break at any time without any warning.
--dev-flag KEY=VALUE Set a development flag to the given value.
Does not have any affect unless --dev is
specified.
--extra-checks Enables additional checks which can catch
more SQL errors, but which incur
additional runtime overhead.
Standard library:
--add-sql-module MODULE_PATH Files from the directory will be treated
as a new SQL module and can be used for
IMPORT. The name of the directory is the
module name.
--override-sql-module MODULE_PATH Will override trace processor module with
passed contents. The outer directory will
specify the module name.
--override-stdlib=[path_to_stdlib] Will override trace_processor/stdlib with
passed contents. The outer directory will
be ignored. Only allowed when --dev is
specified.
Metrics:
--run-metrics x,y,z Runs a comma separated list of metrics and
prints the result as a TraceMetrics proto
to stdout. The specified can either be
in-built metrics or SQL/proto files of
extension metrics.
--pre-metrics FILE Read and execute an SQL query from a file.
This query is executed before the selected
metrics and can't output any results.
--metrics-output=[binary|text|json] Allows the output of --run-metrics to be
specified in either proto binary, proto
text format or JSON format (default: proto
text).
--metric-extension DISK_PATH@VIRTUAL_PATH
Loads metric proto and sql files from
DISK_PATH/protos and DISK_PATH/sql
respectively, and mounts them onto
VIRTUAL_PATH.
Metatracing:
-m, --metatrace FILE Enables metatracing of trace processor
writing the resulting trace into FILE.
--metatrace-buffer-capacity N Sets metatrace event buffer to capture
last N events.
--metatrace-categories CATEGORIES A comma-separated list of metatrace
categories to enable.)",
