OS Load | Redis Documentation
OS Load is the average number of processes using or waiting for the CPU on your node over a period of time.
Average OS load larger than the number of cores indicates that the CPU was temporarily overloaded and reached the limits of its processing capacity. If you are experiencing consistently high OS load and not reaching the desired throughput on your cluster, you may need to tune your data model or add nodes to your cluster to increase processing capacity. Contact Instaclustr Support if you need further assistance in dealing with OS load issues.
