[DESCRIPTION] /psensor-server is a/ It provides a JSON Web service which can be used by psensor(1) to monitor remotely the hardware sensors of a computer. It can provide information about: * the temperature of the motherboard and CPU sensors (using lm\-sensors). * the temperature of the Hard Disk Drives (using hddtemp). * the rotation speed of the fans (using lm\-sensors). It is also possible to connect to the psensor\-server with a browser, a simple Web page is displaying the sensors information and the CPU usage. The URL http://hostname:3131/api/1.0/sensors/[id] returns a JSON object containing all information about a sensor. [id] is the uniq identifier of the sensor. Here is an example of the JSON object of type 'sensor': { "id": "lmsensor acpitz\-virtual\-0 temp1", "name": "temp1", "type": 257, "min": 47.800000, "max": 60.800000, "measures": [ { "value": 47.800000, "time": 1311374873 }, { "value": 49.800000, "time": 1311374878 }, { "value": 49.800000, "time": 1311374883 } ], "last_measure": { "value": 49.800000, "time": 1311374883 } } Fields of the type 'sensor': * id: the uniq identifier of the sensor. * name: a humean readable name of the sensor (might not be uniq). * type: the type of sensor. Look at src/lib/psensor.h for the different types. * min: the minimal value of the sensor. * max: the maximal value of the sensor. * measures: all measures of the sensor. * last_measure: the last value of the sensor. * time: the time of a measure as the number of seconds since 1970/01/01. The URL http://hostname:3131/api/1.0/sensors returns a JSON array containing all JSON objects of type 'sensor'. psensor\-server can be stopped by sending an HTTP request with the URL 'http://hostname:port/api/1.0/server/stop'. [SENSOR LOG FILE] Sensors can be logged using the \-\-sensor-log-file option. It is using a text format, each line is terminated with a NEWLINE char. The first line is: I,%D,%V %D is the starting time of the log expressed as the number of seconds since EPOC. %V is the version of psensor-server. Following lines gives the ordered list of sensors: S,%I,%T %I is the uniq identifier of the sensor. %T is the hexadecimal representation of the sensor type. Then, the values of all sensors are written: %D,%V... %D is the number of seconds elapsed since the starting time of the log. %V... is the list separated by a comma of the current value of all sensors. The ordering is the same than the list of sensor identifiers. The value is expressed as a float with one digit precision. Temperatures are using Celsius unit. The value is written only if it has changed. Example: I,1345974927,0.7.0.4 S,lmsensor coretemp-isa-0000 Physical id 0,101 S,lmsensor coretemp-isa-0000 Core 0,101 S,lmsensor coretemp-isa-0000 Core 1,101 0,37.0,37.0,36.0 5,36.0,,36.0 Five seconds after the log starts, the temperature of the second sensor (Core 0) is still 37C. [WARNING] psensor\-server does not provide any way to restrict the connection to the HTTP server, worst, no effort has been made against malicious HTTP attacks. You should make the psensor\-server port available only to a network or computer you trust by using the usual network security tools of the system (for example, iptables(8) ).
