How do I check my mining hashrate?
I've wrangled an old altcoin mining machine into an ethereum mining rig, it has two Radeon 280X cards in it.
I'm running geth, with two instances of ethminer, one per card. However the output of ethminer is nothing like what I'm used to with the bitcoin equivalent miners. It is very minimal.... it just continually prints:
i <timestamp>|gpuminer0 WorkLoop 1 #1250db29... #1250db29...
over and over.
I've seen posts saying you can benchmark your cards with
ethminer -M -Gbut that just crashes my rig.
Is there any way to get some kind of additional output that could show hashrate?
Make sure your use the latest ethminer and pass a high verbosity flag. I'm using
-v 9. This allows you to follow the hashrate.
ethminer -v 9 -G -F http://ethpool.org/miner/0x00000000000000...
I'm using the version from the Ubuntu repositories:
~ $ ethminer --version ethminer version 1.1.4 Build: Linux/g++/int/Release
Here is the result with hashrate:

Thanks for the reply. It seems I had ethminer version 1.1.3. Using the `-v 9` flag with 1.1.3 did not help. When I followed the instructions on https://github.com/ethereum/webthree-umbrella/wiki/Building-on-Ubuntu it updated it to 1.1.4, and the `-v 9` flag now gives way more output!
