----------------------------------
Summary: channelCounter of SpillableMemoryChannel not register
Key: FLUME-2634
URL: https://issues.apache.org/jira/browse/FLUME-2634
Project: Flume
Issue Type: Bug
Affects Versions: v1.5.2
Reporter: liu xiaofei
when i use SpillableMemoryChannel , the monitor is JSON Report. I saw like this:
"CHANNEL.dmChannel": {
"EventPutSuccessCount": "0",
"ChannelFillPercentage": "0.0",
"Type": "CHANNEL",
"EventPutAttemptCount": "0",
"ChannelSize": "0",
"StopTime": "0",
"StartTime": "1425018740384",
"EventTakeSuccessCount": "0",
"ChannelCapacity": "100000000",
"EventTakeAttemptCount": "0"
}
but my memoryCapacity is 1000000, and overflowCapacity is the default value
100000000. when i refrsh flume's http monitor metrics , this channel's counters
are no change and i'm sure there has data through..
i saw the SpillableMemoryChannel source code and find in function start():
@Override
public synchronized void start() {
super.start();
int overFlowCount = super.getDepth();
if (drainOrder.isEmpty()) {
drainOrder.putOverflow(overFlowCount);
totalStored.release(overFlowCount);
}
int totalCount = overFlowCount + memQueue.size();
channelCounter.setChannelCapacity(memoryCapacity + getOverflowCapacity());
channelCounter.setChannelSize(totalCount);
}
there is no "channelCounter.start()"... so the counter is not registered in
MBeanServer.. and only if the channel overflow the counter will change..
am i correct？
if i am correct, please fix!
ths!
