Changelog

Major (breaking) Changes - Version 3

• works only with node.js v4.0.0 and above (using now internal ES6 promise function, arrow functions, ...)
• Promises. As you can see in the documentation, you can now also use it in a promise oriented way. But callbacks are still supported.
• Async/Await. Due to the promises support, systeminformation also works perfectly with the async/await pattern (available in node.js v7.6.0 and above). See example in the docs.
• cpuCurrentspeed: now returns an object with current minimal, maximal and average CPU frequencies of all cores.
• mem: now supports also newer versions of free (Version 3.3.10 and above); extended information avaliable (potentially available memory)
• fsStats: added information sum bytes read + write (tx) and sum transfer rate/sec (tx_sec)
• networkInterfaces: now providing one more detail: internal - true if this is an internal interface like "lo"
• networkConnections: instead of only counting sockets, you now get an array of objects with connection details for each socket (protocol, local and peer address, state)
• users: now provides an array of objects with users online including detailed session information (login date/time, ip address, terminal, command)
• inetLatency: now you can provide a host against which you want to test latency (default is 8.8.8.8)
• getDynamicData: changed order of parameters (callback - if provided - is now the last one): getDynamicData(srv, network, callback)
• getAllData: changed order of parameters (callback - if provided - is now the last one): getAllData(srv, network, callback)

• FreeBSD support: for some basic functions (new in version 3.34 ff)
• diskLayout: returns hard disk layout (new in version 3.23)
• memLayout: returns memory chip layout (new in version 3.23)
• Windows support: for some basic functions (new in version 3.17 ff)
• cpuCache: returns CPU cache (L1, L2, L3) sizes (new in version 3.14)
• cpuFlags: returns CPU flags (new in version 3.14)
• currentLoad.cpus: returns current load per cpu/core in an array (new in version 3.14)
• shell: returns standard shell e.g. /bin/bash (new in version 3.13)
• blockDevices: returns array of block devices like disks, partitions, raids, roms (new in version 3.10)
• dockerContainerProcesses: returns processes for a specific docker container (new in version 3.8)
• versions: returns object of versions - kernel, ssl, node, npm, ...(new in version 3.6)
• graphics: returns arrays of graphics controllers and displays (new in version 3.5)
• networkInterfaceDefault: returns default network interface (new in version 3.4)
• processes: now returns also a process list with all process details (new in version 3.3)
• battery: retrieves battery status and charging level (new in version 3.2)
• dockerContainers: returns a list of all docker containers (new in version 3.1)
• dockerContainerStats: returns statistics for a specific docker container (new in version 3.1)
• dockerAll: returns a list of all docker containers including their stats (new in version 3.1)
• disksIO: returns overall diskIO and IOPS values for all mounted volumes (new in version 3.0)

Bug Fixes / improvements

• improvement cpuTemperature - works now also on Raspberry Pi
• bugfix disksIO - on OSX read and write got mixed up
• several bug fixes (like assess errors in cpuCurrentspeed, potentially incorrect results in users, ...)
• testet on even more platforms and linux distributions

Be aware, that the new version 3.x is NOT fully backward compatible to version 2.x ...

Major (breaking) Changes - Version 2

There had been a lot of changes in version 2 of systeminformation! Here is a quick overview (for those who come from version 1):

New Functions

• version: returns systeminformation version (semver) of this library
• system: hardware info (manufacturer, product/model name, version, serial, uuid)
• networkConnections: number of active connections
• inetLatency: latency in ms to external resource (internet)
• getStaticData: returns on json object with static data at once (OS, CPU, Network Interfaces - they should not change until restarted)
• getDynamicData: returns on json object with all dynamic data at once (e.g. for monitoring agents)
• getAllData: returns on json object with all data (static and dynamic) at once

Renamed Functions (now all camelCase)

• osinfo: renamed to osInfo
• cpu_currentspeed: renamed to cpuCurrentspeed
• cpu_temperature: renamed to cpuTemperature
• fs_size: renamed to fsSize
• fs_speed: renamed to fsStats
• network_interfaces: renamed to networkInterfaces
• network_speed: renamed to networkStats
• network_connections: renamed to networkConnections
• currentload: renamed to currentLoad
• fullload: renamed to fullLoad
• processload: renamed to processLoad
• checksite: renamed to inetChecksite

Function Changes

• cpu_temperature/cpuTemperature: -1 is new default (and indicates that non sensors are installed)
• cpu_temperature/cpuTemperature: new result max which returns max temperature of all cores
• cpu_currentspeed/cpuCurrentspeed: now in GHz
• cpu: splitted manufacturer (e.g. Intel) and brand (e.g. Core 2 Duo)
• network_speed/networkStats: now better support for OS X (also support for operstate)
• network_speed/networkStats: overall received and transferred bytes (rx, tx)
• mem: now better support for OS X (also support for swaptotal, swapused, swapfree)
• fs_size/fsSize: use-values now in % (0 - 100% instead of 0 - 1)
• fs_speed/fsStats: now also full support for OS X
• checksite/inetChecksite: new result structure - see command reference
• checksite/inetChecksite: ms (former response_ms): -1 if not ok

Other changes

• osx-temperature-sensor: now added as an optional dependency
• no more external dependencies: request is not longer needed
• where possible results are now integer or float values (instead of strings) because it is easier to calculate with numbers ;-)
