A little Google Search turned up the fact that I needed to install php5-json[/u]

Run:

Code:

sudo apt-get install php5-json
sudo service lighttpd force-reload

Reload http://your.ip.address.here/minera/index.php/app/dashboard, and it loaded. Albeit throwing another error about timezone, but I'll deal with that easily.

EDIT: The timezone issue was fixed!
Here is the output from the logs about the timezone issue:

Im trying to cross compile Redis Server on openwrt now.
Can you tell me where to find the folowing missing packages?
The other needed packages i was able to find.

Thanks.

Code:

WARNING: skipping libssp -- package not selected
WARNING: skipping libgfortran -- package not selected

[dloganbill]

For the speed to gain max hashrate, you can save the frequencies table (when you found the good ones) and restart your miner directly with the tuned devices.

Why don't you add a "automatically save and reuse autotuned frequencies" option in the settings page?  Maybe also include a autotune reset button if someone wanted to restart the autotune after miner restart.

[christian1980]

Everybody who wants to help porting Minera to the Wiibox controller
or other cheap AR71XX router like the TP-Link TL-WR1043ND:
We need a Port of the Package "Redis Server" to Openwrt first.
Please post your ideas or try it out yourself.

This is a Makefile for the cross compiling SDK, described here:

Here are the results from my head-to-head comparison against Hashra.  I have two identical RPI setups with qty ten 5-chip miners each.  Since there is no way to distinguish between rigs on Nicehash's website, I used my BTC address for Hashra Controla and Michelem's donation BTC address for the Minera controller. 

Hashra's Dashboard and Nicehash stats
 

Minera's Dashboard, Settings, and Nicehash stats
   

Looking through the log, it looks like it took about 6 hours for the autotune process to finish.  Minera had FAR fewer rejects and HW.  It's hard to tell from a short run like this which is the ultimate winner, but I think that Minera has a solid edge over Hashra.

oh well, this sounds weird, but probably it is an issue with the php version which is different from the Raspbian one. I should do some tests.

hey thank you very much! Nice comparison, if you run it longer tell us your impressions or did you definitely switch to Minera? (and of course thanks for the kind donations)

Since 0.1.8 a/b i´ve got a problem.

If the miner is stoped, Firefox often hangs on the Dashboard page. Sometimes Firefox crashes then.

The other Pages are fine. It's only the Dashboard in stoped mode.

I also get a message sometimes, that <script src="//cdnjs.cloudflare.com/ajax/libs/raphael/2.1.0/raphael-min.js"></script> is hanging and firefox asks if i want to keep it running or stop it.
This happens also, when the miner is running and the dashboard reloads.

[LexMine]

please try to ssh in and:

cd /var/www/minera
sudo ./upgrade_minera.sh

This should fix the logs problem

For the speed to gain max hashrate, you can save the frequencies table (when you found the good ones) and restart your miner directly with the tuned devices.

PS
Email alerting is on roadmap yet

Upgrade worked. Thanks.

i wasn´t talking about the autotuning at this time. i was talking about the displayed hashrate. But i found out, why this is as it is.
cgminer calcualtes the hasrate directly based on the number of processed calculations.
cpuminer makes the calculation based on the accepted shares and so it takes longer until enough accepted shares are there, to make a precise calculation. so at the beginning cpuminer shows a lower hashrate, then it´s realy doing. thats ok for me.

so now let´s talk about autotuning. i already have some ready tuned grids, but somtimes i add a new device. i tried this today with a combination of fixed frequencies and autotuning on, but cpuminer always crashes after a minute. now i have to start the whole autotuning process again for all devices, if i add a single device.
it would be nice to get a button button on the dashboard for every device, like "lock frequency". then i´m able to lock the already autotuned devices and only the new devices should be autotuned. i think this requires work on the minera and the cpuminer source but it would be very usefull for people who change there grids or add new ones from time to time.

Another cool feature would be a rescan devices button. if i add a device, i have to restart cpuminer. else the new device will not be detected. cgminer detects new device when they are pluged to the maschine and adds them without restart.

Cheers... Alex

While Minera should works fine on Firefox I never tested it intensively on it so please can you check if you can re-produce this issue using Chrome?
Thanks

Michelem,

Thanks for adding the current hashrate in the  HTML page title. Makes for tab identification much easier!

Chrome and IE are fine. It´s only Firefox. I use the new Version 29.

It´seams to me, that it´s always the raphael-min.js wich is hanging.

The debugger tells me that on the dashboard there in an empty string assigned to getElementByID in jquery on line 4 but line 4 is very long in the compressed min.js Version :-)

I didn´t realise this error yesterday. it started after updating to version A or B

[fivejonnyfive]

I'm having bad luck trying to use the "saved frequencies" string with 3 5-chip units.

Basically only one miner hashes.

Not sure if the issue is cpuminer or minera. I'll do some more thorough testing and let you know what I find. I wonder is anyone using it successfully?

[SilentH]

Sounds similar to my issue with the blades.. I issue  freq settings but only one chip per in each array use that speed. the others all fall to the default 600. i was seeing it when running directly from command lien so I dont think its related to Minera.
