Some log lines are worth counting but not worth storing. You could already keep the metric and drop the lines through AppSignal MCP, as the MCP log processing workflow shows. The app now does the same with one toggle.x
Turn on Drop log line after metric extraction when you create or edit a log-based metric. AppSignal creates the filter action for you, directly after the metrics action, and keeps it in sync. You keep the metric, and AppSignal stops storing the lines, which reduces log storage costs for high-volume sources. On the Metrics page under Logging, metrics that drop their lines show Drop after match in the Action column.
Log line actions only affect lines that arrive after you save them, and you cannot recover dropped lines. Check that the metric returns the data you expect before you turn the toggle on.
Read the documentation on dropping logs after extracting metrics for how the two actions run. Tell us what you think in our Discord channel.
