Ondat Telemetry

Ondat collects telemetry and error reports from Ondat clusters via two different methods for two different purposes.


  • Telemetry is made up a DNS version check query and a once per day report.
  • Error reporting is the sentry.io crash dump reporting.


Ondat sends crash reports to sentry.io. This information helps our developers monitor and fix crashes. Information is sent to sentry.io when a process inside the Ondat container crashes.

  • The crash report contains the signal that triggered the shutdown (e.g. SIGSEGV), the exit code and whether or not the crash generated a core dump.

All Ondat clusters with a routable connection to the internet will send crash reports to sentry.io over tcp/443. Ondat respects environment variables that ProxyFromEnvironment uses.

An exhaustive list of information included in the crash report is below:

  • Ondat version
  • Crash description string
  • Anonymized Cluster ID
  • Anonymized Node ID

DNS Query

Ondat will perform a “latest version check” using a DNS query in order to inform administrators that a new version is available. Ondat will also send anonymized node IDs, cluster ID and Ondat version information to Ondat using a DNS query. The information that we send in the query is encoded as well as being anonymized. This query allows us to inform Cluster admins when Ondat upgrades are available in the Ondat GUI and in the logs.

The DNS query includes:

  • Anonymized Ondat Cluster ID
  • Anonymized Ondat node ID
  • Ondat version number

Once Per Day Report

The once per day report contains information about the Ondat cluster and Kubernetes versions to help Ondat focus our development efforts on the most popular platforms. The once per day data is encrypted and sent to an Ondat telemetry server so it is never processed outside of Ondat assets.

An exhaustive list of information included in the once per day report is below:

Disable Telemetry

It is possible to disable telemetry using the GUI, CLI, API, environment variables or the Ondat Cluster Spec.

Ondat Cluster Spec

Disable telemetry explicitly through the configurable spec parameters of the StorageOSCluster custom resource.

Environment Variables

You can use the following environmental variables to disable or enable telemetry.

DISABLE_VERSION_CHECK   # Disable the DNS version check
DISABLE_TELEMETRY       # Disable the once per day reporting
DISABLE_ERROR_REPORTING # Disable sentry.io crash reports
