As mentioned in #2605, There are cases when latency may spike due to low iops. Harvest has a parameter latency_io_reqd to handle this but this may need to be tuned further. Below are the steps to modify this in NABox. In below example, we'll change latency_io_reqd to 50. Default value is 10.

⚠️ Note:
Below steps are applicable for NABox and ZapiPerf Collector.

Step 1: Create custom_latency_io_reqd.yaml

Navigate to the zapiperf directory:

cd /opt/harvest2-conf/conf/zapiperf

Create custom_latency_io_reqd.yaml:

vi custom_latency_io_reqd.yaml

Update the file with the following content:

latency_io_reqd: 50

Step 2: Restart NABox containers

dc restart
