View Log discovery because a colleague added a malformed buried point data, resulting in a lot of error.It is inferred that because the use of MEM channel is full, the message is too late to process, resulting in the loss of new data.Modify flume to use the f
For the log, I think the monitoring is not very meaningful, because the speed of writing is generally not particularly fast, but if it is spooldir source, inside a few grams into the data let Flume parse, especially in the combination of Kafka or other framework, monitoring is important, Can analyze the bottleneck of the entire architecture
