logs & stats

app logs

runway app logs displays real-time logs by default. (Mouse)-scroll up to view older logs, scroll to the bottom to see the new log entries as they come in.

The displayed logs are of a couple different categories:

• runtime logs are everything your app writes to stdout or stderr - these are 100% under your control
• build logs, the output of the build stage during runway app deploy
• system logs will usually only come up if your app fails to start or run properly, and may help with debugging

Several options are available:

• --no-build / --no-runtime / --no-system to limit the displayed logs by type
• Use --output quiet/-q (or --noninteractive, or -o json) to switch off real-time updates and just view the last 100 log entries.
• Use --limit [0-1000] to adjust that limit.
• Use the --start and/or --end flags to adjust the time range. By default the whole log retention time span is queried (2 weeks).

app stats

App statistics (CPU, RAM, SSD, network usage) are available via runway app stats.

The displayed range defaults to the last 24h, use --interval 2h to adjust that.

More detailed metrics are available on the web UI.

As with the other runway commands, use --output json to get machine-readable numbers.
