titleCloud collector

We use a piece of software called Collector Server to host and manage all our available collectors. If you want us to host this collector for you, get in touch with us and we will guide you through the configuration.

titleOn-premise collector

This data collector can be run in any machine that has the Docker service available because it should be executed as a docker container. The following sections explain how to prepare all the required setup for having the data collector running.

Structure

The following directory structure should be created for being used when running the collector:

Code Block
<any_directory>
└── devo-collectors/
    └── <product_name>/
        ├── certs/
        │   ├── chain.crt
        │   ├── <your_domain>.key
        │   └── <your_domain>.crt
        ├── state/
        └── config/ 
            └── config.yaml 
Note

Replace <product_name> with the proper value.

Devo credentials

In Devo, go to Administration → Credentials → X.509 Certificates, download the Certificate, Private key and Chain CA and save them in <product_name>/certs/. Learn more about security credentials in Devo here.

Note

Replace <product_name> with the proper value.

Editing the config.yaml file

Info

All defined service entities will be executed by the collector. If you do not want to run any of them, just remove the entity from the services object.

Download the Docker image

The collector should be deployed as a Docker container. Download the Docker image of the collector as a .tgz file by clicking the link in the following table:

Collector Docker image

SHA-256 hash

collector-cisco_umbrella_if-docker-image-1.4.01

13257df8bb2e516db43aec37a30de33659aab3b21404d39a3aeed24e612c1cbe48c399b7a90795a34b2fb2b674781155ebb3ff92ecb52aa0681190a8b6922acb

Use the following command to add the Docker image to the system:

Code Block
gunzip -c <image_file>-<version>.tgz | docker load
Note

Once the Docker image is imported, it will show the real name of the Docker image (including version info). Replace <image_file> and <version> with a proper value.

The Docker image can be deployed on the following services:

Docker

Execute the following command on the root directory <any_directory>/devo-collectors/<product_name>/

Code Block
docker run 
--name collector-<product_name> 
--volume $PWD/certs:/devo-collector/certs 
--volume $PWD/config:/devo-collector/config 
--volume $PWD/state:/devo-collector/state 
--env CONFIG_FILE=config.yaml 
--rm 
--interactive 
--tty 
<image_name>:<version>
Note

Replace <product_name>, <image_name> and <version> with the proper values.

Docker Compose

The following Docker Compose file can be used to execute the Docker container. It must be created in the <any_directory>/devo-collectors/<product_name>/ directory.

Code Block
version: '3'
services:
  collector-<product_name>:
    image: <image_name>:${IMAGE_VERSION:-latest}
    container_name: collector-<product_name>
    volumes:
      - ./certs:/devo-collector/certs
      - ./config:/devo-collector/config
      - ./credentials:/devo-collector/credentials
      - ./state:/devo-collector/state
    environment:
      - CONFIG_FILE=${CONFIG_FILE:-config.yaml}

To run the container using docker-compose, execute the following command from the <any_directory>/devo-collectors/<product_name>/ directory:

Code Block
IMAGE_VERSION=<version> docker-compose up -d
Note

Replace <product_name>, <image_name> and <version> with the proper values.
