tmartino@chromium.org bling-transactions@google.com Records the specific error encountered when parsing bookmarks. This is independent of other data types; it's possible for this to fail but another data type to subsequently be imported. tmartino@chromium.org bling-transactions@google.com The total time taken for the user data import process to complete, end to end, once the input file(s) have been presented to the importer. Note that this may include time waiting for UI actions in some cases. tmartino@chromium.org bling-transactions@google.com Records the specific error encountered when preparing passwords, generally indicating an issue with parsing. This is independent of other data types; it's possible for this to fail but another data type to subsequently be imported. tmartino@chromium.org bling-transactions@google.com Records the specific error encountered when parsing reading list items. This is independent of other data types; it's possible for this to fail but another data type to subsequently be imported. tmartino@chromium.org bling-transactions@google.com Records the specific error which caused the entire import process to fail, if such an error occurred. An error in this histogram would indicate that no data was successfully imported for any data type. tmartino@chromium.org bling-transactions@google.com The total size of the input file or data package provided for the user data import process, in KB. tmartino@chromium.org bling-transactions@google.com The size of the data to be imported for this data type, in KB. fsenra@google.com treib@chromium.org Records when the import for the data type has started or completed. fsenra@google.com treib@chromium.org The time taken to parse the data and import it into the user's storage for the data type. Recorded once the import for the data type is completed. tmartino@chromium.org bling-transactions@google.com The time taken to import the data into the Chrome backends. Note that other parts of the flow, like UI steps, file IO, parsing, etc. may have occurred before this step, so this is not necessarily a total duration. fsenra@google.com treib@chromium.org The number of items successfully imported for this data type. Recorded once the import for the data type is completed. tmartino@chromium.org bling-transactions@google.com Records the final outcome of attempting to import a given data type. tmartino@chromium.org bling-transactions@google.com The number of items prepared for import for this data type. Note that in certain cases (notably history, which is parsed in a streaming manner) this may be an estimate, with actual parsing to occur later. tmartino@chromium.org bling-transactions@google.com The time taken to prepare the data for import for this data type. Usually this involves parsing, but note that in certain cases (notably history, which is parsed in a streaming manner) this may not encompass all parsing work that is done in the entire pipeline. tmartino@chromium.org bling-transactions@google.com The percentage of prepared items that were successfully imported (ImportedCount / PreparedCount) for this data type. Note that in some cases PreparedCount is an estimate, which means we could get over 100%.
