Testing out the new Influx DB Line Protocol Data Source

  • Hello,

    While testing the data source, the help section indicates the following -

    There are 2 env properties that configure how the Line Protocol endpoint behaves.

    lineProtocol.task.queueWarningSize - Size of line queue at to which raise an event warning of queue growth
    lineProtocol.pointValidation.cacheExpirySeconds - When creating data points Mango will cache the existing points on this data source for performance during validation, this is how long they should live in the cache

    These 2 lines do not exist in the file. Could you provide an example of what the recommended defaults should be?

    Thank you.

  • The defaults that will be used if no property exists are:

    lineProtocol.task.queueWarningSize: 10000
    lineProtocol.pointValidation.cacheExpirySeconds: 5000

    Basically you will have to experiment with your setup and these would only need to be adjusted when you see performance degradation.

  • Thank you, Terry.

    While testing, I am using the following input

    # Processor usage, alternative to native, reports on a per core.
    ObjectName = "Processor"
    Instances = [""]
    Counters = [
    "% Idle Time",
    "% Interrupt Time",
    "% Privileged Time",
    "% User Time",
    "% Processor Time",
    "% DPC Time",
    Measurement = "win_cpu"
    # Set to true to include _Total instance when querying for all (

    The message to be sent is the following

    win_cpu,host=LAPTOP,instance=2,objectname=Processor,source=telegraf Percent_DPC_Time=0,Percent_Idle_Time=89.79866790771484,Percent_Interrupt_Time=0,Percent_Privileged_Time=0,Percent_Processor_Time=3.9585533142089844,Percent_User_Time=3.098111152648926 1604960081000000000

    What is making it to Mango ends up looking like this

    Along with some additional errors for points that failed to be created.

    I do have Treat integers as Numeric types checked but seem to keep getting NumberFormatExceptions and Invalid Line Length errors. Can Mango only handle a single value being sent at a time?

    Thank you.
