Logging

For detailed information and analysis on obtaining logs for other system components, see the documentation for the kata-log-parser tool.

For runtime logs, see the following sections for the CRI-O and containerd shimv2 based runtimes.

Kata OCI

The Kata OCI runtime (including when used with CRI-O), provides --log= and --log-format= options. However, the runtime also always logs to the system log (syslog or journald).

To view runtime log output:

$ sudo journalctl -t kata-runtime

Kata containerd shimv2

The Kata containerd shimv2 runtime logs through containerd, and its logs will be sent to wherever the containerd logs are directed. However, the shimv2 runtime also always logs to the system log (syslog or journald) under the identifier name of kata.

To view the shimv2 runtime log output:

$ sudo journalctl -t kata
