Description

Server for collecting autoscale plot data from autoscale leader(s).

{autoscale_server, true} in the config will enable this service. The autoscale processes from which data is collected assume that this server runs in the same VM as mgmt_server (needs to be set in config).

{autoscale_server_plot_path, PATH} needs to be set in order to write the collected data to the file system (see on({write_to_file})).

Data Types

message()

message() = 
    {collect,
     PlotKey :: atom(),
     Timestamp :: pos_integer(),
     Value :: number()} |
    {reset} |
    {write_to_file}

state()

state() = 
    {PlotData ::
         dict:dict(PlotKey :: atom(),
                   {Timestamp :: pos_integer(), Value :: number()})} |
    unknown_event
