       psensor-server - Temperature and system monitoring Web server


       psensor-server [OPTION]...


       psensor-server is an HTTP server for monitoring hardware sensors remotely.

       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

       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


       -h, --help
              display this help and exit

       -v, --version
              display version information and exit

              webserver port

              directory containing webserver pages

       -d, --debug=LEVEL
              set the debug level, integer between 0 and 3

       -l, --log-file=PATH
              set the log file to PATH

       --sensor-log-file=PATH set the sensor log file to PATH

       --sensor-log-interval=S set the sensor log interval to S (seconds)


       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

       The value is written only if it has changed.

       Example: I,1345974927, 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

       Five seconds after the log starts, the temperature of the second sensor (Core 0) is  still


       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) ).
