Minimum configuration required for basic pulling

Although this collector supports advanced configuration, the fields required to retrieve data with basic configuration are defined below.

This minimum configuration refers exclusively to those specific parameters of this integration. There are more required parameters related to the generic behavior of the collector. Check setting sections for details.

Setting	Details
`api_key`	The API key for Trellix API.
`username`	The username to generate the auth token for authentication.
`password`	The username to generate the auth token for authentication.

The auth token timeout specified in Trellix DLP official documentation is 300 seconds, but we are using it as 280 seconds as the token expires around that time.

Accepted authentication methods

Authentication method	api_key	username	password
Bearer auth token	REQUIRED	REQUIRED	REQUIRED

Run the collector

Once the data source is configured, you can either send us the required information if you want us to host and manage the collector for you (Cloud collector), or deploy and host the collector in your own machine using a Docker image (On-premise collector).

Collector services detail

This section is intended to explain how to proceed with specific actions for services.

dpim incident

Verify data collection

Once the collector has been launched, it is important to check if the ingestion is performed in a proper way. To do so, go to the collector’s logs console.

This service has the following components:

Component	Description
Setup	The setup module is in charge of authenticating the service and managing the token expiration when needed.
Puller	The setup module is in charge of pulling the data in a organized way and delivering the events via SDK.

Setup output

A successful run has the following output messages for the setup module:

A successful initial run has the following output messages for the puller module:

Note that the PrePull action is executed only one time before the first run of the Pull action.

After a successful collector’s execution (that is, no error logs found), you will see the following log message:

2024-07-12T12:37:41.589    INFO InputProcess::TrellixDLPPuller(trellix_dlp,65768,incidents,predefined) -> (Partial) Statistics for this pull cycle (@devo_pulling_id=1720768050631):Number of requests made: 2; Number of events received: 872; Number of duplicated events filtered out: 0; Number of events generated and sent: 872; Average of events per second: 79.628.

Restart the persistence

This collector uses persistent storage to download events in an orderly fashion and avoid duplicates. In case you want to re-ingest historical data or recreate the persistence, you can restart the persistence of this collector by following these steps:

Edit the configuration file.
Change the value of the initial_start_time_in_utc_value parameter to a different one.
Save the changes.
Restart the collector.

The collector will detect this change and will restart the persistence using the parameters of the configuration file or the default configuration in case it has not been provided.

Note that this action clears the persistence and cannot be recovered in any way. Resetting persistence could result in duplicate or lost events.

Troubleshooting

This collector has different security layers that detect both an invalid configuration and abnormal operation. This table will help you detect and resolve the most common errors.

Error type	Error ID	Error message	Cause	Solution
`InitVariablesError`	`1`	initial_start_time_in_utc is not set as per the datetime_format : {datetime_format}	The date in config is not as per required format	Ensure the date format is correct.
`InitVariablesError`	`2`	Date {initial_start_time_str} is in the future	The date in config is greater than current time	Ensure the datetime is less than current time
`SetupError`	`100`	HTTP Error occurred while generating auth token from trellix server	Wrong credentials	Check the credentials and ensure that the collector has the necessary permissions to access the Trellix API.
`SetupError`	`101`	Some error occurred while generating auth token from trellix server. Error details: {e}	Generate auth token api failed	Contact the developer with exact error message.
`SetupError`	`102`	Unable to generate auth token with status code as {response.status_code}	Generate auth token api failed	Contact the developer with exact error message.
`SetupError`	`103`	HTTP Error occurred while fetching apim incident from trellix server	Trellix API call is failing	Check the credentials and ensure that the collector has the necessary permissions to access the Trellix API.
`PullError`	`300`	HTTP Error occurred while fetching apim incident from trellix server	Trellix API call is failing	Check the credentials and ensure that the collector has the necessary permissions to access the Trellix API.
`PullError`	`301`	Some error occurred while fetching apim incident from trellix server. Error details: {e}	Trellix API call is failing	Contact the developer with exact error message.

Check memory usage

To check the memory usage of this collector, look for the following log records in the collector which are displayed every 5 minutes by default, always after running the memory-free process.

The used memory is displayed by running processes and the sum of both values will give the total used memory for the collector.
The global pressure of the available memory is displayed in the global value.
All metrics (Global, RSS, VMS) include the value before freeing and after previous -> after freeing memory

INFO InputProcess::MainThread -> [GC] global: 20.4% -> 20.4%, process: RSS(34.50MiB -> 34.08MiB), VMS(410.52MiB -> 410.02MiB)
INFO OutputProcess::MainThread -> [GC] global: 20.4% -> 20.4%, process: RSS(28.41MiB -> 28.41MiB), VMS(705.28MiB -> 705.28MiB)

Differences between RSS and VMS memory usage:

RSS is the Resident Set Size, which is the actual physical memory the process is using
VMS is the Virtual Memory Size which is the virtual memory that process is using
