Configure the Datadog Webhook LAM

The Datadog Webhook LAM receives and processes Datadog events forwarded to Moogsoft Onprem. The LAM parses the data into Moogsoft Onprem events.

You can install a basic Datadog Webhook integration in the UI. See Datadog Webhook for integration steps.

Configure the Datadog Webhook LAM if you want to configure custom properties, set up high availability or configure advanced options that are not available in the UI integration.

Before You Begin

Before you configure the Datadog Webhook LAM, ensure you have met the following requirements:

You have an active Datadog account.
You have the necessary permissions to create a webhook in Datadog.
Datadog can make requests to external endpoints over port 443. This is the default.

If you are configuring a distributed deployment refer to High Availability Overview first. You will need the details of the server configuration you are going to use for HA.

Configure the LAM

Edit the configuration file to control the behavior of the Datadog Webhook LAM. You can find the file at $MOOGSOFT_HOME/config/datadog_lam.conf

The Datadog Webhook LAM is a REST-based LAM as it provides an HTTP endpoint for data ingestion. Note that only the generic REST LAM properties in datadog_lam.conf apply to the Datadog Webhook LAM; see the LAM and Integration Reference for a full description of all properties.

Some properties in the file are commented out by default. Uncomment properties to enable them.

Configure the connection properties for the REST connection:
- address: Address on the Moogsoft Onprem server that listens for REST messages. Defaults to all interfaces.
- port: Port on the Moogsoft Onprem server that listens for REST messages. Defaults to 48007.
Configure authentication:
- authentication_type: Type of authentication used by the LAM. Defaults to none.
- authentication_cache: Whether to cache the username and password for the current connection when the authentication type is Basic.
Configure the LAM behavior:
- accept_all_json: Allows the LAM to read and process all forms of JSON.
- lists_contain_multiple_events: Whether Moogsoft Onprem interprets a JSON list as multiple events.
- num_threads:Number of worker threads to use.
- rest_response_mode: When to send a REST response. See the LAM and Integration Reference for the options.
- rpc_response_timeout: Number of seconds to wait for a REST response.
- event_ack_mode: When Moogfarmd acknowledges events from the Datadog Webhook LAM during the event processing pipeline.
Configure the SSL properties if you want to encrypt communications between the LAM and the REST connection:
- use_ssl: Whether to use SSL certification.
- path_to_ssl_files: Path to the directory that contains the SSL certificates.
- ssl_key_filename: The SSL server key file.
- ssl_cert_filename: The SSL root CA file.
- use_client_certificates: Whether to use SSL client certification.
- client_ca_filename: The SSL client CA file.
- auth_token or encrypted_auth_token: Authentication token in the request body.
- header_auth_token or encrypted_header_auth_token: Authentication token in the request header.
- ssl_protocols:Sets the allowed SSL protocols.
Optionally configure the LAM identification and capture logging details:
- name: Maps to $Laminstancename, so that the agent field indicates events Moogsoft Onprem ingests from this LAM.
- capture_log: Name and location of the LAM's capture log file, which it writes to for debugging purposes.
Optionally configure severity conversion. See Severity Reference for further information and "Conversion Rules" in Tokenize Source Event Data for details on conversions in general.
Optionally configure the process logging details:
- configuration_file: Name and location of the LAM's process log configuration file. See Configure Logging for more information.Configure Logging

Example

An example Datadog Webhook LAM configuration is as follows.

monitor:
{
    name                          : "Datadog Lam",
    class                         : "CRestMonitor",
    port                          : 48007,
    address                       : "0.0.0.0",
    use_ssl                       : false,
    #path_to_ssl_files            : "config",
    #ssl_key_filename             : "server.key",
    #ssl_cert_filename            : "server.pem",
    #use_client_certificates      : false,
    #client_ca_filename           : "ca.crt",
    #auth_token                   : "my_secret",
    #encrypted_auth_token         : "dfJtTQMGiFHfiq7sCmxguBt6Jv+eytkoiKCquSB/7iWxpgGsG2aez3z2j7SuBtKj",
    #header_auth_token            : "my_secret",
    #encrypted_header_auth_token  : "dfJtTQMGiFHfiq7sCmxguBt6Jv+eytkoiKCquSB/7iWxpgGsG2aez3z2j7SuBtKj",
    #ssl_protocols                : [ "TLSv1.2" ],
    authentication_type           : "none",
    authentication_cache          : true,
    accept_all_json               : true,
    lists_contain_multiple_events : true,
    num_threads                   : 5,
    rest_response_mode            : "on_receipt",
    rpc_response_timeout          : 20,
    event_ack_mode                : "queued_for_processing"
},
agent:
{
    name                          : "DataDog",
    capture_log                   : "$MOOGSOFT_HOME/log/data-capture/datadog_lam.log"
},
log_config:
{
     configuration_file           : "$MOOGSOFT_HOME/config/logging/datadog_lam_log.json"
{,

Configure for High Availability

Configure the Datadog Webhook LAM for high availability if required. See High Availability Overview for details.

Configure LAMbot Processing

The Datadog Webhook LAMbot processes and filters events before sending them to the Message Bus. You can customize or bypass this processing if required. You can also load JavaScript files into the LAMbot and execute them.

See LAMbot Configuration for more information. An example Datadog Webhook LAM filter configuration is shown below.

filter:
{
    presend: "DatadogLam-SolutionPak.js",
    modules: [ "CommonUtils.js" ]
}

Start and Stop the LAM

Restart the Datadog Webhook LAM to activate any changes you make to the configuration file or LAMbot.

The LAM service name is datadoglamd.

See Control Moogsoft Onprem Processes for the commands to start, stop and restart the LAM.

You can use a GET request to check the status of the Datadog Webhook LAM. See "Check the LAM Status" in Configure the REST LAM for further information and examples.

Configure Datadog

After you have the Datadog Webhook LAM running and listening for incoming requests, you can configure Datadog. See "Configure Datadog" in Datadog Webhook.
