Hi Paul, That looks really helpful. However, I'm missing a bit of context - what is generating those metrics? i.e., is there a utility class/program in the Flume jar I run to obtain it? That looks like JSON - what generates it?

It’s one of the main metrics we alert on (well ChannelFillPercentage, actually). Snippet from one of my nodes: "CHANNEL.fc_WebLogs": { "EventPutSuccessCount": "1285941800", "ChannelFillPercentage": "1.8881", "Type": "CHANNEL", "EventPutAttemptCount": "1285941800", "ChannelSize": "18881", "StopTime": "0", "StartTime": "1387357632600", "EventTakeSuccessCount": "1285944090", "ChannelCapacity": "1000000", "EventTakeAttemptCount": "1287200957" }, Hope that helps, Paul Chavez From:Andy Yang [mailto:[email protected]] Sent: Thursday, January 02, 2014 2:07 PM To: [email protected] Subject: File Channel Contents Hi Are there any utils out there that will analyze a file channel and return information about it? I've found the blog article here: https://blogs.apache.org/flume/entry/apache_flume_filechannel which is very useful and seems to suggest that I could whip up some code using FileChannel and LogFile classes. However, it seems like this would be something that people previously might have had a need for. While browsing individual events would be nice, even just a reliable count of the number of events in the queue would be hugely useful. Thanks
