storageinfo

the storageinfo object provides information about a storage device connected to the player to retrieve information about the filesystem on the device, use the filesystem object see technical best practices docid\ qceva3ocmvet4jzt5l6pe for more information about device storage paths storageinfo idl \[ constructor(string path, string type) ] interface storageinfo { promise\<number> getdevicesize(); promise\<storagedeviceinfo> getdeviceinfo(); promise\<storagedevicehealth> getdevicehealth(); }; interface storagedeviceinfo { attribute string type; attribute number size; \[type == "sd"] attribute sddeviceinfo sd; \[type == "sata"] attribute satadeviceinfo sata; }; interface sddeviceinfo { attribute string productname; attribute string oemid; attribute string ausize; //@optional attribute string productrev; attribute string mfrdate; //@optional attribute string serial; //@optional attribute string signalvoltage; attribute string uhsmode; attribute number specversion; attribute string speedclass; //@optional attribute number mfrid; }; interface storagedevicehealth { attribute int percentagehealthused; }; interface satadeviceinfo { attribute string satamodel; attribute string satavendor; }; object creation to create an storageinfo object, first load the brightsign/storageinfo module using the require() method then create an instance of the storageinfo class with a string value specifying the storage path var storageinfoclass = require("@brightsign/storageinfo"); var storageinfo = new storageinfoclass("/storage/sd"); use the following string values to specify different storage drives "/storage/usb1" – the drive for usb storage devices connected to the player "/storage/sd" – the primary sd or microsd drive on the player "/storage/sd2" – the internal microsd drive on the player (4kx42, xdx32 models only) "/storage/ssd" – the internal ssd on the player (xtx44, xtx43, xdx34, and xdx33 models only) "/storage/flash" the internal flash storage on the player storageinfo use this interface to retrieve information about the storage device getdevicesize() promise \<number> getdevicesize returns the total size of the storage device (in bytes) the size returned by this method uses a different tool from the size parameter in the storagedeviceinfo interface the values returned using the two processes will be approximately, but not exactly, the same getdeviceinfo() promise \<storagedeviceinfo> getdeviceinfo() returns a storagedeviceinfo interface containing manufacturer information about the storage device getdevicehealth() promise\<storagedevicehealth> getdevicehealth() returns a "card wear" indication in the form of a percentage this value is approximate and is provided to assist in scheduling proactive replacements to avoid in field failures once this value reaches 100, the card is life expired and further attempts to write to the card may fail this feature is only supported on certain industrial type cards such as the micron and sandisk cards supplied by brightsign storagedeviceinfo this interface contains manufacturer information about the storage device any of the below parameters may be absent from the interface depending on the device type and the information returned by the device type string string the type of filesystem used on the specified storage size number number the total size of the storage device (in bytes) sddeviceinfo sd \[type == "sd"] sd \[type == "sd"] returns details about the sd card hardware satadeviceinfo sata\[type == "sata"] sata\[type == "sata"] returns details about the serial ata (sata) interface sddeviceinfo productname string string the product name, as assigned by the device manufacturer (5 bytes for sd, 6 bytes for mmc) oemid string string the two character card oem identifier as assigned by the sd card association ausize number number optional optional the size of the sd au in bytes productrev string string the product revision assigned by the device manufacturer mfrdate string string optional optional the manufacture date reported by the storage device serial string string optional optional the serial number of the storage device signalvoltage string string the signal voltage reported by the sd card uhsmode string string the uhs mode (i e bus speed) reported by the sd card specversion number number the version of sd spec to which the card conforms speedclass string string optional optional the speed class (if any) declared by the sd card mfrid number number the card manufacturer id as assigned by the sd card association storagedevicehealth percentagehealthused int int returns an integer that indicates the "wear percentage" of disk health used, on micron and sandisk storage cards that support this feature satadeviceinfo satamodel string string the sata model reported by the device satavendor string string the sata vendor reported by the device example var storageclass = require("@brightsign/storageinfo"); var storage = new storageclass("/storage/usb1"); storage getdevicesize() then( function(data) { console log(json stringify(data)); }) catch( function(data) { console log(json stringify(data)); }); storage getdeviceinfo() then( function(data) { console log(json stringify(data)); }) catch( function(data) { console log(json stringify(data)); });
