chrome_main_thread_hotspots
Top main-thread tasks by duration with ts, upid/pid, cpupct, and optional page-load/time-window filters
chrome_page_load_resource_hotspots
URL-bearing resource/request slices on thread, process, and async tracks ranked by page-load/window overlap, with process/thread identity where available
chrome_page_load_resource_pipeline
One URL's lifecycle/request spans joined with background parse, script evaluation, and style/layout signals, plus an evidence boundary for DNS/TLS/TTFB/cache/download hypotheses
chrome_page_load_resource_summary
Compact URL-level resource/request summary for page-load windows, ranked by max overlap with normalized origin, navigation/renderer relatedness, and attribution-scope evidence
chrome_page_load_script_hotspots
Renderer main-thread script execution grouped by URL/slice/process within a page-load/window, with style/layout descendant signals
chrome_page_load_summary
Page loads: URL, raw boundary timestamps, FCP, LCP, DCL, load timings (ms)
chrome_scroll_jank_summary
Worst janky frames with cause, sub-cause, delaysincelastframe
chrome_startup_summary
Browser startup events and time-to-first-visible-content
chrome_web_content_interactions
Web content interactions (clicks, taps, INP) ranked by duration
execute_sql
Run a PerfettoSQL query (max 5000 returned rows). Prefer the dedicated chrome / list tools for standard analyses; use this for custom joins or aggregations they don't expose. Output shaping: head/limit, summary, columnsonly, includerowcount, maxstringlen. Sensitive URL/header/cookie/path values reda
list_processes
List processes (pid, name, start/end timestamps)
list_stdlib_modules
List PerfettoSQL stdlib modules, optional domain / query / limit filters (no trace needed)
list_table_structure
Show column names and types for a table
list_tables
List tables/views in the loaded trace, optional GLOB filter
list_threads_in_process
List threads under a process name (up to 2000)
load_trace
Open one trace with path, or several with paths; returns an opaque traceid and lightweight routing summary for each file (type/profile, duration, platform, process/thread counts, capabilities, redaction policy, recommended next tools)
slice_descendants_breakdown
Summarize child slices under a long slice id without hand-writing recursive CTEs
