Interactive trace processor shell.
Usage: %s [OPTIONS] trace_file.pb
Options:
-h, --help Prints this guide.
-v, --version Prints the version of trace processor.
-d, --debug Enable virtual table debugging.
-W, --wide Prints interactive output with double
column width.
-p, --perf-file FILE Writes the time taken to ingest the trace
and execute the queries to the given file.
Only valid with -q or --run-metrics and
the file will only be written if the
execution is successful.
-q, --query-file FILE Read and execute an SQL query from a file.
If used with --run-metrics, the query is
executed after the selected metrics and
the metrics output is suppressed.
--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.
-D, --httpd Enables the HTTP RPC server.
--http-port PORT Specify what port to run HTTP 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.
--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.
--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).
-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.
--full-sort Forces the trace processor into performing
a full sort ignoring any windowing
logic.
--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.
--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.
--override-stdlib=[path_to_stdlib] Will override trace_processor/stdlib with
passed contents. The outer directory will
be ignored. Only allowed when --dev is
