Worker names are used to distinguish miners, thus helping identify problematic devices quickly.
If you are running multiple devices without setting worker names, all your devices can only be displayed as one miner in your pool dashboard. Settings like this will probably increase your time to examine the issue, and it is also not possible to get offline alerts about individual miners from the pool. Thus, if you are running multiple miners, we suggest you set a worker name for each of your devices.
How to set worker names
Most coins that mine with GPU and CPU miners do not have batch management tools. Therefore, you will need to change multiple miner numbers one by one, which could be troublesome. In this situation, similar parameters can be used to generate worker names. Set up a mining command with the worker name %computername%, as shown below:
nbminer -a ethash -o eth.f2pool.com:6688 -u username.%computername%
After the command is set, transfer the mining software to the appropriate mining machine, and your worker names should be generated automatically according to the computer name format.
