New stratum/getwork proxy with Web-based GUI and pools management

[Pfool]

What are this lines and how can i optimize them?

  "poolHashrateSamplingPeriod" : 600,
  "userHashrateSamplingPeriod" : 600,
  "connectionHashrateSamplingPeriod" : 600,
  "hashrateDatabaseSamplingPeriod": 60,
  "hashrateDatabaseHistoryDepth": 7,

  "poolHashrateSamplingPeriod" : 600,
  "userHashrateSamplingPeriod" : 600,
  "connectionHashrateSamplingPeriod" : 600,

These lines control the time of share capture to estimate the pools, users and connections hashrate. The default value (600 seconds) keep all shares for 10 minutes and estimate the hashrate based on these shares.

  "hashrateDatabaseSamplingPeriod": 60,

This line control the time between hashrate estimation snapshots. With the default value (60 seconds), the hashrate of pools, users and connections are saved in database each minute. (on the hashrate charts, you will have a sample every minutes)

  "hashrateDatabaseHistoryDepth": 7,

This line control the history depth of the hashrate data kept in database. With the default value (7 days), all data that are older than 7 days will be discarded.

Can someone please post a working config file for nicehash sha-256 config please, I would like to point several S3 Antminers to my box thats running this program and then point the box at nicehash.. Any help would be much appreciated.

This basic configuration file should work (just replace the "user" value with your BTC address) :

Code:

{
  "pools" : [ {
    "name" : "Nicehash SHA-256",
    "host" : "stratum.nicehash.com:3334",
    "user" : "19wv8FQKv3NkwTdzBCQn1AGsb9ghqBPWXi",
    "password" : "d=2048",
    "enableExtranonceSubscribe" : true,
  }  ]
}

This configuration file is the minimal configuration with default values for all other parameters.

If you want to use Stratum, just point your miner to stratum+tcp://proxyIp:3333. Else, to use Getwork, point your miner to http://proxyIp:8332. The username and password configured in your miner can be anything.

Hello, is there a way to optimize the ram usage?
I made it run on rasp pi(using the precompiled .zip) and i noticed that it starts with 10.1% of ram usage and then it slowly grow up to 18.8%(84148Kb) up to now( after near 10 hours ).
The proxy is set to only show error log.
It would be nice if it can be optimized for devices like rasp pi(not so ram equipped).

Another thing is "weightedRoundRobinRoundDuration", i set it to "5" but it's not really mining 5 minutes then switch to other pool, but it switch much early, like 1 minute or so. Or could be i'm wrong with what that "5" means lol.
My config is:

Code:

"poolConnectionRetryDelay" : 5,
  "poolReconnectStabilityPeriod" : 5,
  "poolNoNotifyTimeout" : 240,
  "rejectReconnectOnDifferentHost" : false,
  "poolHashrateSamplingPeriod" : 600,
  "userHashrateSamplingPeriod" : 600,
  "connectionHashrateSamplingPeriod" : 600,
  "isScrypt" : true,
  "databaseDirectory": "",
  "hashrateDatabaseSamplingPeriod": 60,
  "hashrateDatabaseHistoryDepth": 7,
  "noMidstate": false,
  "apiLogLevel": "INFO",
  "validateSha26GetworkShares": true,
  "poolSwitchingStrategy": "weightedRoundRobin",
  "weightedRoundRobinRoundDuration": 5,

and every pool has "weight" : 1 . The pool is the same, just with 4 different accounts and it's a scrypt pool( doge ).
It's not that problem, mining seems to works good anyway, just to talk if the round of "X minutes" is really as expected.
Thanks for the proxy!  

For the memory consumption, you can try to add the following parameters on your command line:
-Xms:32M -Xmx:32M

These parameters tells the JVM to only allocate 32 MB of memory for the Heap (by the real memory consumption can be greater since the JVM itself need memory). With this parameters, you should see a lower memory footprint of the proxy, but you will surely see a higher CPU consumption. You can try to tweak the value (always the same value for both parameters). If you get a OutOfMemoryError at some point, the parameters is to low. (With only 2 miners, I have succeeded to run the proxy with 16M for several hours).


For the WeightedRoundRobin, the round duration is the value of a total round. For example, if the round duration is 5 minute and you have 5 pools with weight 1, each pool will mine for 1 minute before switching (at the end of the round, all counters are reset).
You can calcul the pool mining duration with the following formula (when no pool is down):

poolMiningDuration = poolWeight * (roundDuration / sumOfWeights)

[Goldenboyz]

Thanks!
That explain really good what i was missing about the round duration  
And for the ram usage, i was starting with -Xmx100m, after your words i'm trying with -Xmx64m and -Xms64m(as u said 32 seems to be good to stay near 72Mb of ram usage, with no impact in cpu usage) see if i can mitigate a bit.
For ram reduction, does the parameter "hashrateDatabaseHistoryDepth" affect the ram usage by any means? I set it from 7 to 1 hoping it can save cpu and/or ram  

p.s. i sent you a little donation for a couple of beers  , thanks for the software and for the support!

Thank you for the donation 

The hashrateDatabaseHistoryDepth will not impact memory consumption since the records are stored on-disk. To lower the memory cunsomption, you could try to disable the getwork protocol if you do not need it:
"disableGetwork" : true,

And lower a bit the Xmx value

[Goldenboyz]

i think that 73-78Mb(with "32" ) is the minimum amount to have everything fine with decent cpu usage, i tried "16" and the amount of ram was 58Mb but i had sporadic spikes in cpu usage.
i disabled getwork, i'll check how it goes, thanks.

Do i need to install java in the server to use the web-based client?

[Pfool]

You need java on the server to run the proxy (the whole proxy, including the API server which is used by the client).

The web-client is available through your prefered browser on http://proxyIp:8888 (by default). The browser only need Javascript to be enabled. (No need for java on the client side)

I don't know what is wrong with the installation,I have followed the steps below,kindly see below :
I have brand new server with IP : xxx:xxx:yyy:yy
1.I installed LAMP. http://IP is working....
2. I git cloned : https://github.com/Stratehm/stratum-proxy.git
3.I installed java.
4.I verified java.
5.I checked : http://IP:8888 not working..

Any thing to add on the above lines?

On another note, I have installed the proxy on a windows box, athlon dual core. the cpu load is fine, one user works with miningrigrentals, two and it's choking, hashrate is all over the place, stop/start.

You just made a typo error. replace .jar by -jar on the command line

java -jar stratum-proxy.jar --help, not java .jar stratum-proxy.jar --help

I don't know what is wrong with the installation,I have followed the steps below,kindly see below :
I have brand new server with IP : xxx:xxx:yyy:yy
1.I installed LAMP. http://IP is working....
2. I git cloned : https://github.com/Stratehm/stratum-proxy.git
3.I installed java.
4.I verified java.
5.I checked : http://IP:8888 not working..

Any thing to add on the above lines?

After the git clone, do you have followed the packaging steps of the README file ? To package the proxy from the git repo, you will need the JDK version of java (not only the JRE) and you will need to have maven installed.

It is easier to download a release package and unzip it in a folder. Then, edit the configuration file and launch the proxy with the following command line:
java -jar stratum-proxy.jar -f /path/to/config/file.conf

use this: https://github.com/Stratehm/stratum-proxy/releases/download/0.5.1/stratum-proxy-0.5.1.zip
If you git clone, you need maven to compile the project 

[Goldenboyz]

Do i need to install java in the server to use the web-based client?

you need java for everything of this project.

By the way, is there a a way to connect to the proxy with a fixed user/pass?
I mean, now everyone could connect with an arbitrary user/pass, i there a way to make it "private" so only me, or who knows user/pass, can connect it?
I don't mean the web part.

No, there is no such feature in this proxy since this proxy was primarily developped for use in a private network.

As far as I am concerned, I would be very happy if some unknown guys want to connect on my proxy instance and give me their hashing power, I would not try to restrict them the access

LOL 
that is just to be sure that someone can't do something wrong at the proxy, like flooding or anything else.
I'm a bit paranoid, i know

It makes sense, but I think the probabilities are so low that this feature will be with a low priority on the TODO list.

[Goldenboyz]

better than nothing  
if i have time i'll look into it.
