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.
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
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
See the debugging section of the developer guide.
