Where are TPM 2.0 selftest messages logged?

Hopefully, this is a simple question regarding hardware I'm just now learning how to use: the TPM. My laptop has a TPM 2.0, and I need to become familiar with some basic functionality offered by the tpm2-tools package. To start, I confirmed that the tpm2-abrmd (the daemon) service is active. Then I ran

sudo tpm2_selftest -V

and was expecting a verbose output in the terminal. However, nothing is output in the terminal when I execute the command. The manual describes the messages sent by the TPM but not *where* they are sent/logged. I checked /var/log/syslog but found nothing. Does anyone know where the messaging data is stored? Or if it *is* stored, for that matter?
