Foxglove agent option to ignore bags actively recording

[tonynajjar]

Foxglove agent currently only allows to ignore file based on their name, however rosbag2 currently does not offer a way to mark active bag files with e.g. a suffix. When foxglove agent tries to ingest a bag being recorded it throws the error:

{"message":"Failed to ingest rosbag2_2024_04_11-10_17_14/rosbag2_2024_04_11-10_17_14_0.mcap: failed to summarize input rosbag2_2024_04_11-10_17_14/rosbag2_2024_04_11-10_17_14_0.mcap: failed to read magic: EOF"

It would be nice if Foxglove agent had an extra option to ignore bags being recorded, in other words "open files" (e.g. with lsof)

FYI with agent v1.1.4 we've added new logic that will ignore incomplete mcap files in the watched directory: https://docs.foxglove.dev/changelog/agent/v1.1.4

This should reduce the error spam you are seeing.

Yeah thanks for that. "Reduce" is the keyword though. It still produces continuous logs that it's skipping the files though. It would have been nice to even skip these logs.
