Startup tracing with memory profiling

  • See this page for general information about memory tracing.
There are two ways to perform memory tracing at startup:

Simple way with default configuration (one memory dump every 250 ms., one detailed memory dump every 2 s.)

$chrome --no-sandbox \
        --trace-startup=-*,disabled-by-default-memory-infra \
        --trace-startup-file=/tmp/trace.json  \
        --trace-startup-duration=7

Then just load /tmp/trace.json in chrome://tracing


Advanced, memory tracing configuration
If you need more advanced configuration (e.g., higher granularity dumps, no need for detailed memory dumps) specify a custom trace config file, as follows:

$ cat > /tmp/trace.config
{
  "startup_duration": 4,
  "result_file": "/tmp/trace.json",
  "trace_config": {
    "included_categories": ["disabled-by-default-memory-infra"],
    "excluded_categories": ["*"],
    "memory_dump_config": {
      "triggers": [
        {"mode":"light", "periodic_interval_ms": 50},
        {"mode":"detailed", "periodic_interval_ms": 1000}
      ]
    }
  }
}


$chrome --no-sandbox --trace-config-file=/tmp/trace.config
