Carbon Black Cloud Syslog Connector

Brand New CBC Syslog 2.0.3 Released

The Syslog Connector lets administrators forward alerts and audit logs from their Carbon Black Cloud instance to local, on-premise systems, and:

  • Generates customizable templated syslog messages
  • Aggregates data from one or more Carbon Black Cloud organizations into a single syslog stream
  • Can be configured to transport syslog messages using one of the following UDP, TCP, encrypted (TCP over TLS), HTTP(S), or local file

For more information on the Syslog Connector checkout the github README

To update from Syslog 1.x, read the migration guide on GitHub


The Data Forwarder is the recommended export method for reliable and guaranteed delivery of Carbon Black Cloud Alerts. This method works at scale to support any size customer or MSSP by writing jsonl zipped content to an S3 bucket. The Data Forwarder can be configured in the Carbon Black Cloud console under Settings > Data Forwarder or using the Data Forwarder API.

The Alerts API can be used to build a custom integration. Further details on how to consume the Alerts API can be found in the Alert Bulk Export Guide.


  • Any Carbon Black Cloud product
Note: The Syslog Connector is not supported in the AWS GovCloud (US) environment.

The cbc_syslog_forwarder poll command is designed to be executed in a cronjob or scheduled task for continual syslog forwarding

If you are a first time user try the setup command to walkthrough creating a config file. Feel free to update and customize the config file to meet your needs.


Create a file to save the cronjob such as syslog-job.txt. Cronjobs use the UNIX cron format for specifying the schedule for the job to be executed

5  *  *  *  *  cbc_syslog_forwarder --log-file /some/path/cbc-syslog.log poll /some/path/my-config.toml

To start the job once the file is created run the following command

crontab syslog-job.txt
