Issue/Introduction
The CABI Group Availability report for VMWARE metrics shows 99% when all samples in the timeframe are 1.
The expectation should be 100% as there has been no downtime.
We have already deployed the fix mentioned in the below KB but the issue is not resolved. it is still showing 99%.
If we capture all the samples from a given machine for the given period, all the samples are all equal to 1 for the QOS_VMWARE_VM_POWER_STATE which feeds this Report.
We have also seen cases where the calculation is completely wrong even showing 30% for 100% uptime periods.
Environment
UIM 20.4 CU4/5 CABI 7.5/8.0
uim_cabi_availability_report_pack 1.11HF1
Cause
Non-recommended VMWARE metrics polling interval can cause this issue. For example. VMware time interval set to 30min (1800) can cause this issue.
The recommendation is 10 minutes:
Resolution
In the VMWARE probe configuration please decrease the interval time from 30min(1800). to: 10 min(600).
After this run a report over the period gathered with 10 minutes interval and check if the result of the report is accurate.
