PROTOCOLS
Collector
Defined in fuchsia.memory.inspection/inspection.fidl
Obtains the memory usage of a fuchsia device.
CollectJsonStats
Writes to socket a JSON capture of the memory usage and the memory
bucket definition, as a well-formed UTF-8 string.
The socket is closed by the server after all the data is written into
it.
TODO(https://fxbug.dev/42073090): Document the schema of the JSON.
Sample output: {"Capture": { "Time":28477260758625, "Kernel":{ "total":1610612736, "free":170565632, "wired":67395584, "total_heap":30904320, "free_heap":1873728, "vmo":1276194816, "mmu":65294336, "ipc":196608, "other":61440 }, "Processes":[ ["koid","name","vmos"], [47325,"fonts.cm",[47353, ...]], ... ], "VmoNames":["scudo:primary", ...], "Vmos":[ ["koid","name","parent_koid","committed_bytes","allocated_bytes"], [47440,38,47437,4096,4096], ... ] } "Buckets": [ { "event_code": 29, "name": "BlobfsInactive", "process": "blobfs\.cm", "vmo": "inactive-blob-.*" }, ... ] }
For size reasons: - Processes and Vmos have an initial entry that contains the names of the the fields in the rest of the entries. - The names of the VMOs are an index into the VMONames array.
