Kinesis Log Watcher

Watch Kinesis logs in real time.

Usage

kinesis-log-watcher [options] stream-name

Watch incoming log entries from a Kinesis stream. This is intended to be a companion to kinesis-log-streamer.

Valid durations are a number followed by a unit abbreviation. Examples: 30s, 5m, 3h, 1d.

The format string uses the Go template format. Fields available are:

• {{.HostId}} {{.HostID}} -- The full ARN of the host generating the log.
• {{.ShortHostId}} {{.ShortHostID}} -- Short hostname (just the last part).
• {{.Timestamp}} -- The timestamp when the log was sent to Kinesis.
• {{.LogEntry}} -- The log entry in string format.
• {{.Log}} -- If the log entry could be parsed as JSON, the resulting JSON structure. You can get embedded fields using {{.Log.FieldName}}.

To format the timestamp in different formats (e.g. ISO 8601), you can use either:

• {{.Timestamp Format "2005-01-02T15:04:05Z"}} or
• {{strftime "%Y-%m-%dT%H:%M:%S" .Timestamp}}
