Issue/Introduction

We are receiving huge no of CPU alerts with sample 1 when we have set the no of samples to 3 in the CDM cfg file and on checking this is only happening after the server gets reboot.

Environment

• Release: 20.3 or higher
• Component: UIM - CDM WITH IOSTAT
• cdm v6.60

Cause

• Send alarm on each sample: allows you to generate an alarm on each sample, if selected.
• If not selected, the probe waits for the number of samples (specified in the Samples field of the Control properties tab) before sending the alarm.
• For example, if the Interval value is 1 minute and the Samples value is 2 under the Control Properties tab, and if this option is:
  • Unchecked: the probe generates the first alarm in 2 minutes and respective alarm at 1 minute interval.
  • Checked: the probe generates the first alarm in 1 minute and each respective alarm at 1 minute interval.

Resolution

Unchecking the following option ''Send alarm on each sample'' solves the issue.
