fio_benchmark_exporter's Issues

custom benchmark trigger a latency benchmark

Hello,
First of all, thank you for this great job, this exporter is exactly what we are looking for.

We want to run some custom benchmark, but it looks like actually it is running a latency benchmark.
Here is the args set in my deployment :

args: ['-benchmark=custom -customBenchmarkFioFlags="--name=toto --status-interval=30 --numjobs=1 --ioengine=libaio --direct=1 --bs=4k --iodepth=1 --readwrite=randrw --directory=/tmp --size=1G --runtime=60 --time_based --lat_percentiles=1 --clat_percentiles=0 --group_reporting"']

Here is the log of the pod :

2022/06/02 14:47:25 Listening on :9996 2022/06/02 14:47:25 Configured schedule: 0 */6 * * * 2022/06/02 14:47:25 Running fio: fio --name=latency --numjobs=1 --ioengine=libaio --direct=1 --bs=4k --iodepth=1 --readwrite=randrw --directory=/tmp --size=1G --runtime=60 --time_based --output-format=terse --terse-version=5 --lat_percentiles=1 --clat_percentiles=0 --group_reporting 2022/06/02 14:48:30 Fio update: [5 fio-3.12 latency 0 0 ...] 2022/06/02 14:48:30 Benchmark complete

When I hit "ps auxf" inside the pod during the benchmark, I can see that :

Is there something I'm not doing correctly ?
