InfluxData offers a set of tools that are well-purposed for load testing:
InfluxDB is a time series database that is very good for storing measurements generated during load testing
Telegraf is a client that can report performance-related OS measurements to InfluxDB (CPU%, Memory%, bandwidth, network and disk I/O, etc). Useful for monitoring both the load generators and the servers.
Chronograf is a visualization tool for time-series databases – very handy for visualizing and analyzing load test measurements.
