    lic-agent-sdk&gt; Agent SDK.

METHODS

 new

    Instantiates a new NewRelic::Agent client object.

        my $agent = NewRelic::Agent-&gt;new(
            license_key          =&gt; $license_key,
            app_name             =&gt; $app_name,

        );

    Parameters

    - license_key

      A valid NewRelic license key for your account.

      This value is also automatically sourced from the
      NEWRELIC_LICENSE_KEY environment variable.

    - app_name

      The name of your application.

      This value is also automatically sourced from the NEWRELIC_APP_NAME
      environment variable.

    - app_language

      The language that your application is written in.

      This value defaults to perl, and can also be automatically sourced
      from the NEWRELIC_APP_LANGUAGE environment variable.

    - app_language_version

      The version of the language that your application is written in.

      This value defaults to your perl version, and can also be
      automatically sourced from the NEWRELIC_APP_LANGUAGE_VERSION
      environment variable.

 embed_collector

    Embeds the collector agent for harvesting NewRelic data. This should be
    called before init, if the agent is being used in Embedded mode and not
    Daemon mode.

    Example:

        $agent-&gt;embed_collector;

 init

    Initialize the connection to NewRelic.

    Example:

        $agent-&gt;init;

 begin_transaction

    Identifies the beginning of a transaction, which is a timed operation
    consisting of multiple segments. By default, transaction type is set to
    WebTransaction and transaction category is set to Uri.

    Returns the transaction's ID on success, else negative warning code or
    error code.

    Example:

        my $txn_id = $agent-&gt;begin_transaction;

 set_transaction_name

    Sets the transaction's name.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;set_transaction_name($txn_id, 'Create Account');

 set_transaction_request_url

    Sets the transaction's request url. The query part of the url is
    automatically stripped from the url.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;set_transaction_request_url($txn_id, 'api.myapp.com/users/123');

 set_transaction_max_trace_segments

    Sets the maximum number of trace segments allowed in a transaction
    trace. By default, the maximum is set to 2000, which means the first
    2000 segments in a transaction will create trace segments if the
    transaction exceeds the trace theshold (4 x apdex_t).

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;set_transaction_max_trace_segments($txn_id, 5000);

 set_transaction_category

    Sets the transaction's category name (.e.g Uri in
    "WebTransaction/Uri/&lt;txn_name&gt;").

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;set_transaction_category($txn_id, 'Custom');

 set_transaction_type_web

    Sets the transaction type to WebTransaction. This will automatically
    change the category to Uri.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;set_transaction_type_web($txn_id);

 set_transaction_type_other

    Sets the transaction type to OtherTransaction. This will automatically
    change the category to Custom.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;set_transaction_type_other($txn_id);

 add_transaction_attribute

    Sets a transaction attribute. Up to the first 50 attributes added are
    sent with each transaction.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;add_transaction_attribute($txn_id, 'User-Agent', 'Mozilla/5.0 ...');

 notice_transaction_error

    Identify an error that occurred during the transaction. The first
    identified error is sent with each transaction.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;notice_transaction_error(
            $txn_id,
            'Runtime error',
            'Illegal division by zero',
            "Illegal division by zero at div0.pl line 4.\nmain::run() called at div0.pl line7",
            "\n",
        );

 end_transaction

    Identify the end of a transaction.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;end_transaction($txn_id);

 record_metric

    Record a custom metric.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;record_metric('cache_miss_timing', 0.333333);

 record_cpu_usage

    Record CPU user time in seconds and as a percentage of CPU capacity.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;record_cpu_usage(2.1, 0.85);

 record_memory_usage

    Record the current amount of memory (in megabytes) being used.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;record_memory_usage(745);

 begin_generic_segment

    Identify the beginning of a segment that performs a generic operation.
    This type of segment does not create metrics, but can show up in a
    transaction trace if a transaction is slow enough.

    Returns the segment's ID on success, else negative warning code or
    error code.

    Example:

        my $seg_id = $agent-&gt;begin_generic_segment($txn_id, undef, 'Parse zip codes');

 begin_datastore_segment

    Identify the beginning of a segment that performs a database operation.
    This uses the default sql_obfuscator that strips the SQL string
    literals and numeric sequences, replacing them with the ? character.

    Returns the segment's ID on success, else negative warning code or
    error code.

    Example:

        my $seg_id = $agent-&gt;begin_datastore_segment(
            $txn_id,
            undef,
            'users',
            'selecting user',
            'SELECT * FROM users WHERE id=?',
            'get_user_account',
        );

 begin_external_segment

    Identify the beginning of a segment that performs an external service.

    Returns the segment's ID on success, else negative warning code or
    error code.

    Example:

        my $seg_id = $agent-&gt;begin_external_segment(
            $txn_id,
            undef,
            'http://api.stripe.com/v1',
            'tokenize credit card',
        );

 end_segment

    Identify the end of a segment.

    Returns 0 on success, else negative warning code or error code.

    Example:

        my $err_id = $agent-&gt;end_segment($txn_id, $seg_id);

 get_license_key

    Returns the license key that the agent has loaded. This is useful for
    diagnostic purposes.

    Example:

        my $license_key = $agent-&gt;get_license_key;

 get_app_name

    Returns the application name that the agent has loaded. This is useful
    for diagnostic purposes.

    Example:

        my $app_name = $agent-&gt;get_app_name;

 get_app_language

    Returns the application language that the agent has loaded. This is
    useful for diagnostic purposes.

    Example:

        my $app_language = $agent-&gt;get_app_language;

 get_app_language_version

    Returns the application language's version that the agent has loaded.
    This is useful for diagnostic purposes.

    Example:

        my $app_language_version = $agent-&gt;get_app_language_version;
