To view the system log, use the
vespa-logfmt utility. This formats and filters the raw log.
The log on admin server(s) includes log lines from all the Vespa nodes in your system.
/opt/vespa/bin/vespa-logfmt -l warning,errordisplays all errors and warnings.
If you run Docker you need to go inside the Docker container to run this, so do
docker exec -it [container-name] bashfirst.
If you encounter something like
INFO: Problem with Handshake localhost:8080 ssl=false: localhost:8080 failed to respondwhen feeding, or
No datawhen querying, it usually means the node is set up with isufficient memory + swap and is too busy swapping data to get anything done. If you are running Docker on your laptop, you need to increase memory for the container under Preferences - Advanced.
