* cmd/trace: fix the broken link in region pages and improve UXRohith Ravi2020-04-211-3/+13
| | | | | | | | | | | | | | | | | | | | The trace tool had a broken link due to a parameter encoding error, which has been corrected. In addition: - the user regions page has been enhanced to include links to pprof style profiles for region specific io, block, syscall and schedwait profiles. - sortable table headers have a pointer cursor to indicate they're clickable.

* cmd/trace: revert internal/traceparserHana Kim2018-11-221-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | The performance improvement is not as big as we hoped. Until the API is feature complete, we postpone the release and avoid added complexity. This change was prepared by reverting all the changes affected src/cmd/trace and src/internal/traceparser packages after golang.org/cl/137635, and then bringing back MMU computation APIs (originally in src/internal/traceparser) to the src/internal/trace package. Revert "cmd/trace: use new traceparser to parse the raw trace files" This reverts https://golang.org/cl/145457 (commit 08816cb8d7ed16b9c804587ff02c1ad1c3af6cd5). Revert "internal/traceparser: provide parser that uses less space and parses segments of runtime trace files" This reverts https://golang.org/cl/137635 (commit daaf361f74c3665bcb364356c5a9dd9f536c78c3).

* cmd/trace: beautify goroutine pageHana (Hyang-Ah) Kim2018-03-261-59/+175
| | | | | | | | | | | | | | | | | | - Summary: also includes links to pprof data. - Sortable table: sorting is done on server-side. The intention is that later, I want to add pagination feature and limit the page size the browser has to handle. - Stacked horizontal bar graph to present total time breakdown. - Human-friendly time representation. - No dependency on external fancy javascript libraries to allow it to function without an internet connection.

* cmd/trace: compute pprof-style output per goroutine typeHana (Hyang-Ah) Kim2017-11-301-7/+10
| | | | | | | | | | | | | | | | | | | The trace command computes IO, Schedule, Block, and Syscall profiles by following the unblocking links in the execution trace and summing up the duration. This change offers variations of those profiles that include only selected goroutine types. The id parameter takes the goroutine type - i.e. pc of the goroutine. The output is available from the /goroutine view. So, users can see where the goroutines of interest typically block. Also, these profiles are available for download so users can use pprof or other tools to interpret the output. This change adds links for download of global profile in the main page.

* cmd/trace: add new commandDmitry Vyukov2015-02-201-0/+328
Trace command allows to visualize and analyze traces. Run as: $ go tool trace binary trace.file The commands opens web browser with the main page, which contains links for trace visualization, blocking profiler, network IO profiler and per-goroutine traces. Also move trace parser from runtime/pprof/trace_parser_test.go to internal/trace/parser.go, so that it can be shared between tests and the command.
