Usage

Firstly u need ensure working influx database.

Initialization

PViewer.init(
     {
         driver: 'influx',
         time_precision: 'u',
         database: 'db_name',
         measurement: 'ms_name'

First hash is for database configuration, all options at influxdb-ruby. Passing second hash allows to set up GUI.

Collectors

PViewer allows to collect data details in three defined ways:

• duration,
• amount (counter),
• values.

PViewer.durations
PViewer.counters
PViewer.values

collector.write(tags: {}, values: {}, time: Time.now.to_i)

Data fetching

Mentioned above collectors allows also to read data with the possibility of setting filters and reductions of complex data.

    counter = PViewer.counters(measurement: 'cities')
    counter.read(tags: { city: 'New York' }, reduce: :sum)

GUI is disabled by default, to run it:

    PViewer.run_gui
