A fast Graphite relay

graphite-relay's Issues

Add a license?

I would like to use some of your code to implement some load tests against Graphite using Iago (https://github.com/twitter/iago) but wont be able to publish them unless you declare a license. Without specifying, the copyright defaults to 'all rights reserved'.

Can you take a moment to drop a LICENSE file you like in the repo? It'd be much appreciated :)

Too many CLOSE_WAIT connections

After some running (20 minutes) on our test environment I fount that relay open tons of connections to client:
root@graph:/# netstat -apn | grep 25782 | grep ESTA | wc -l
1297
root@graph:/# netstat -apn | grep 25782 | grep CLOS | wc -l
2669
As far as I understand these connections are holded by Netty. How can I mitigate this?

Thanks!

Startup errors

Hello,

I would like to use this graphite-relay app with one of my projects, but the issue is that I have not been able to lunch the relay server (graphite-relay-0.2.7.jar).

Is it necessary to have any additional jar in the classpath?

java -version

java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)

java -jar graphite-relay-0.2.7.jar -c graphite-relay.properties

Working with Graphite 0.9.11 ?

Hi Mark,

Trying to test your relay against our installation of Graphite 0.9.11 - relay and 4 caches with consistent hashing.
Found everything "working" but graphs on Graphite-web looks totally wrong - like we loosing all caches but one:

Checked that's not true - all 4 caches got updates, and all updates went to disk.
So, my idea was that hashing algorithm in your implementation differs than what Graphite use, and I found that you use just simple CRC32:
https://github.com/markchadwick/graphite-relay/blob/master/src/main/scala/backend/strategy/ConsistentHash.scala#L39-43
but Graphite use int( md5hex() [:4])
https://github.com/graphite-project/carbon/blob/master/lib/carbon/hashing.py#L16-19
https://github.com/graphite-project/graphite-web/blob/master/webapp/graphite/render/hashing.py#L66-69
Could you please tell me if I'm right and providing proper hashing will help? ('cause I'm not very good at scala and I want to spend my time on this patch only if I'm thinking right)

Thanks!

Compiling the graphite-relay

Hi Mark,

Sorry for the dumb question. If I have to compile the source code, do I need to compile it in openjdk-7? Can you point me to some documentation for the same for me to do the same?

If the documentation is in progress, is there a jar file uploaded somewhere that I can use? I would be happy to help you with the documentation.
