Getting Started

In order to insert records into an Azure Log Analytics instance, you can run the plugin from the command line or through the configuration file:

Command Line

The azure plugin, can read the parameters from the command line in two ways, through the -p argument (property), e.g:

$ fluent-bit -i cpu -o azure -p customer_id=abc -p shared_key=def -m '*' -f 1

Configuration File

In your main configuration file append the following Input & Output sections:

[INPUT]
    Name  cpu

[OUTPUT]
    Name        azure
    Match       *
    Customer_ID abc
    Shared_Key  def

Another example using the Log_Type_Key with record-accessor, which will read the table name (or event type) dynamically from kubernetes label app, instead of Log_Type:

[INPUT]
    Name  cpu

[OUTPUT]
    Name        azure
    Match       *
    Log_Type_Key $kubernetes['labels']['app']
    Customer_ID abc
    Shared_Key  def
