Collector

Image

Started from version 5.2 we build our docker.io image from scratch (0 size image). Collector image contains a binary (collectord), the set of root certificates and timezone database. Our collector is a statically compiled binary. We use a Go language to produce this binary. We do not use dynamic runtime. Our binary only can do what we programmed it to do.

Alternatively, we provide a certified image hosted on RedHat registry. This image is based on RHEL image. We keep it up to date and track vulnerabilities in the base image.

Container configuration

To be able to collect logs and metrics from the Cluster, the collector needs to have access to the host filesystem. Because of that, our container requires privileged access. Collectord treats the host as read-only, the only information it writes to the host is the acknowledgement information in the form of the database. By default, it writes it under /var/lib/colllectorforopenshift, and if a volume database is requested, it writes it under in the volume root.

If you don't use the volume database, you can change the permission for the host filesystem to read-only, but you need to provide a write access to the Collectord primary database directory (data folder).

Collectord also requires Read-Only access to the API Server. We limit the access to the API Server with RBAC to be able to read data from the API Server.

Using secrets to manage configurations

Please follow our instructions to learn how to use secrets to manage Token and License Key.

Internet access

Default license requires internet access for the license verification. We can offer a license, that does not require internet access.

Collector forwards telemetry to our license server. You can turn off telemetry with our configuration.

Connection to Splunk HTTP Event Collector

We recommend using SSL for connection to Splunk HEC. Please follow our manual on how to configure secure SSL connection between the collector and Splunk HEC.
