Sitecore Managed Cloud Standard (MCS) – PaaS 1.0 Monitoring Metrics


Overview

This article provides a detailed list of default metrics monitored by the Sitecore Cloud Operations team for all Managed Cloud customers. More metrics might be included in future releases.

For more information about the Managed Cloud Standard monitoring description, refer to the service aspects article.

Description

Azure Monitoring and Alerts are based on a tier system. The tiers range from Tier 1, (which has the highest frequency of alerts and cost per alert), through to Tier 3, (which is queried every 15 minutes for alerts). Tier 3 alert is triggered if the condition matches the alert threshold. Tier 3 also has the lowest cost per alert. Sitecore also offers free Tier 4 ping test alerts. They are metric alert and activity log alert. Currently, metric alert is free if the subscription only has equal to or fewer than 10 units, and the activity log alert is free.

Note: Further pricing details are available via your aligned Account Executive or Customer Success Manager.

Importance of Monitoring and Customer Technical Contacts in Sitecore Managed Cloud Standard

The Sitecore Managed Cloud team communicates with the designated Customer Technical Contact on all matters related to alerts, availability, and maintenance. By default, this is defined in the Sitecore Customer Order section of the Managed Cloud contract:

Customer Technical Contact Name:[name of contact]
Customer Technical Contact Email:[email of contact]

This contact list can be one or more recipients and is managed through the Sitecore account team. Customers are discouraged from fully delegating this Technical Contact responsibility to a partner, or third party, because it can limit visibility to important system-wide notifications.

Important Note: The monitoring package does not yet support the following deployment types: Sitecore Single topologies: XP0, XM0, XDB0.

Monitoring rules are set up for all Sitecore Managed Cloud Standard environments. For production environments, the Sitecore Managed Cloud team actively triages each alert and escalates incidents as appropriate. For non-production environments, customers can choose to respond as they prefer, but the Sitecore Managed Cloud team does not actively triage.
