Description of messages in the FearMiner window

How to read FearMiner's cockpit — the header, the hashrate block, the per-card rows and the log underneath.

What can you see in the miner window?

The header

FEAR MINER 1.1.0  stratum+tcp://qtc.kryptex.network:7049  connected 41 ms  qzoy…H2oa  up 1m11s  fee 2.00%

Version, the pool in use, the round-trip time to it, the wallet shortened, uptime and the dev fee. A wallet is shown only after its checksum has been verified.

Hashrate and totals

The big figure is the local hashrate — what the cards compute. Beside it a ten-minute chart with min, avg and max.

The row under it: shares accepted and rejected, current diff, the best share found, luck, eff, kH/W and the current streak of accepted shares. eff is the effective hashrate — what the pool actually credits over the last fifteen minutes. It stays - until ten shares have been accepted, because below that the figure means nothing.

The per-card rows

GPU0  NVIDIA CMP 50HX                                            348.22 MH/s
  temp 82°C  fan 60%  power 0/225 W  clock 1725 MHz  eff 30644164.99 kH/W
  shares 3  acc/rej 3/0  last 4 s ago

Each card carries its own hashrate, telemetry and share counters. acc/rej is the pool's verdict on that card's shares; stale ones are shown in parentheses and mean latency, not a faulty card. A card with rejects that are not stale is the one to look at. power cap next to the power bar means the card is sitting at its limit.

The log

The start block states what the miner is about to do: wallet with (checksum ok), worker, pool, custody, algo, the driver it found, one gpu #N line per card with its compute capability and free memory, the stats and api addresses, the fee rate, the build with the SHA-256 of the running binary, and egress — every host the miner will talk to.

Then the working lines: each job from the pool with its difficulty, and each share as accepted/total, the card that found it, its difficulty and the time the pool took to answer.

Error lines carry a stable code — E1xx network, E2xx configuration, E3xx hardware, E4xx wallet, E5xx kernel. fearminer explain E302 prints the cause and what to do about it.
