our assumptions about latency as returned by hystrixCommandCompletion:
# a latency of >= 0 indicates that this the execution occurred.
# a latency of == -1 indicates that the execution didn't occur (default in execution result)
# a latency of < -1 indicates some clock problems.
We will only count executions, and ignore non-executions with a value of -1.
Latencies of < -1 are ignored as they will decrement the counts, and Prometheus will
take this as a reset of the counter, therefore this should be avoided by all means.
