Hi,

I am using flume for transferring logs from 20 agent boxes to 1 collector box. The file size which I am trying to transfer is of about 1 GB per hour. So every hour my agents run to transfer the log file generated during the last hour.
I am using DFO sink for file transfer.

But then I am facing following problems:

1) Some of the agents are not able to transfer the whole file even in one hour and the processes run continuously for hours.
2) Some of the agents stop within 5-6 minutes without sending the file completely.

I want to know

1) if somebody else has faced the same issues?
2) What could be the problem?

Thanks
Chandrashekhar Shaw
 

Hi,

Which one of the sources are you using? Maybe a flume source that
implements something like
http://docs.jboss.org/netty/3.2/xref/org/jboss/netty could be useful.

Harish

I am using Flume - OG   https://github.com/downloads/cloudera/flume/flume-distribution-0.9.4-bin.tar.gz .

It there an available version which implements netty??

Hello,

Not too sure about Flume OG - I barely used it for a week before shifting
to NG. Would there be any particular reason you are using OG?

Yes, you can take a look at SyslogTcpSource (in NG),
https://people.apache.org/~mpercy/flume/flume-1.2.0-incubating-SNAPSHOT/docs/apidocs/org/apache/flume/source/SyslogTcpSource.html

This can be modified according to this Netty example (for asynchronous
large file streaming) :
http://static.netty.io/3.5/xref/org/jboss/netty/example/http/file/package-summary.html
This is pretty much what I did when I needed a Flume HTTP source to match
my requirements.

Hi

I was testing flume for log transfer in DFO mode. I was firing the single shot command as cron every 10th minute from the agent box. So the flume process starts every 10 minutes sends the logs to collector box and ends.

It was pushing the logs very well. To test the reliability I stopped the collector and brought it back after 1 hour, what I see is

* The flume process (started by the agent cron) kept on running in the agent machine and not able to transfer the rest of the file to collector.
* The process did not end even after 5/6 hours. (I had to manually kill it).

As I know flume agent should continue sending the log once the collector is re-started. ???
Is there something I am missing ??

Thanks

Chandrashekhar,  

Is there a specific reason you cannot use Flume NG. I believe that has already been suggested on this thread. Flume OG is no longer actively developed, and it is better to move to Flume NG - which had its second release a few weeks back - Flume v 1.2.0.
Thanks
Hari

Hi Harish,

Thanks for quick response..

No, Actually I did not try flume-ng. Flume-og was working good for me..

Just curious to know does flume-ng supports encrypted  channel ?

Thanks

Not at the moment, but there is already effort to support encryption in file channel:

Or I would rather say "Does flume-ng provide encrypted channel ??"

Hi Chandrashekhar,
When you say encrypted channel, can you be more specific about what you are
referring to? i.e. encrypted on-disk or encrypted on the wire?

Mike

Hi Harish,

I meant encrypted channel.

Thanks

Hi,

I am using flume for transferring logs from 20 agent boxes to 1 collector box. The file size which I am trying to transfer is of about 1 GB per hour. So every hour my agents run to transfer the log file generated during the last hour.
I am using DFO sink for file transfer.

But then I am facing following problems:

1) Some of the agents are not able to transfer the whole file even in one hour and the processes run continuously for hours.
2) Some of the agents stop within 5-6 minutes without sending the file completely.

I want to know

1) if somebody else has faced the same issues?
2) What could be the problem?

Thanks
