Use the built-in problem and alert signatures in vRealize Log Insight for vRealize Operations Manager. You create one instance of each alert in Region A and in Region B because the vRealize Operations Manager instance in the SDDC works in the context of both management and compute resources in each region. The SDDC also contains one analytics cluster that is failed over to Region B and you receive alerts only about it.

About this task

For monitoring the vRealize Operations Manager deployment in the Software-Defined Data Center, you can use the following alerts in vRealize Log Insight:

Table 1. vRealize Operations Manager Alerts in vRealize Log Insight

Alert Name

Purpose

Severity

vRops: VC stats query timed out occurred

The purpose of this alert is to notify when vROPs instance is not able to get the data back from vCenter instance within the 5 minute interval and the metrics back up and get dropped with the error: Communication Error: com.integrien.adapter.vmware.VcCollector.collectMetrics - Vc stats query timed out (ms): 300377. This is usually due to intermittent connection issues with the vCenter and hosts or down to the network not able to handle the request and timing out.

Critical

vRops: Out of Memory errors occurred

This alert gets generated when OutOfMemoryError: Java heap space occurs. This could indicate memory issues and could lead to degradation in performance.
