Observability options using Red Hat OpenShift with VMware vSphere concepts

5 mins

When your infrastructure is finally up and running with a new tool, it’s time to keep it running smoothly. In this resource we will learn how to access common observability features in Red Hat® OpenShift®, and what each of the Red Hat® OpenShift® Virtualization observability menu options mean for VMware vSphere admins.

What will you learn?

  • How OpenShift menu and features map to ones you may know from VMware

What do you need before starting?

  • VMware vSphere 8.0 or higher (as referenced in this path)
  • Red Hat OpenShift (as referenced in this path)

Observability feature mapping chart

This section addresses commonly used observability features in VMware and how they map to deploying, managing, and maintaining virtual machines in OpenShift.

Notification/Alarm on Triggers

Custom alarm provides rules definition on events, condition or state triggers, severity levels can be set
OpenShift Observability provides rules definition. Severity levels can be set and have discrete actions for each level.
Variety of Notifications Targets Custom Alarm provides for emails and SNMP traps configuration as well as script execution Alertmanager provides default handlers for email, webhook, and several 3rd party apps including Slack, PagerDuty, and MSTeams (See Notes for full list)
Event logging Provides a per-VM advanced option to Enable logging to a log file called vmware-n.log Vector/Loki/Logging Console plugin has replaced the traditional Elasticsearch/Fluentd/Kibana stack to provide greater insights and better observability
Log Shipping Host logs can be shipped from vCenter to alternate locations/3rd party logging apps Vector multi log forwarder feature supports multiple Red Hat and 3rd party logging applications

Menu mapping chart

This section addresses what the OpenShift Virtualization observability menu selection items mean from a VMware vSphere perspective. As noted in previous resources, OpenShift is conceptually different in select areas from VMware to achieve the same or similar items.These instances will be marked as "N/A" in the list below.

OpenShift Virtualization menu item VMware comparable Explanation
Alerting Task and Events Shows list of events
Metrics Task and Events Show performance data for VMI/pods
Dashboards Performance > Overview/Advance Performance dashboards
Target Integration Access with account/passwords List of services that can be monitored
