Zerto

Application Version and Upgrade Details

Introduction

In a virtual environment, Zerto, a Hewlett Packard Enterprise company is a ransomware resilience, disaster recovery (DR), and multi-cloud mobility solution that offers write-order fidelity near-synchronous replication with no impact on product workloads. Workloads may be secured, moved, and recovered either inside the same hypervisor environment, across hypervisor environments, and/ or to and from public cloud sites like Azure. Both the protected and the recovery locations have Zerto installed. A browser-based user interface controls the catastrophe recovery across various sites. Zerto may also be managed programmatically through a Swagger (REST API) interface.

Built for enterprise scale, Zerto’s simple, software only solution uses continuous data protection (CDP) to eliminate the risks and complexity of modernization and cloud adoption by empowering companies to run an always-on business by simplifying the protection, recovery, and mobility of on-premises and cloud applications.

Except for the actual replication of data, Zerto Virtual Manager Appliance (ZMVA) is a Linux-based service that controls everything needed for replication across protection and recovery locations. The Zerto User Interface maintains this protection once the ZVMA communicates with the hypervisor administration user interface, such as vCenter Server or Microsoft SCVMM, to obtain the inventory of VMs, discs, networks, hosts, etc. Moreover, the ZVMA keeps track of modifications to the hypervisor environment and reacts appropriately.

Prerequisites

• OpsRamp Classic Gateway 14.0.0 and above.
• OpsRamp NextGen Gateway 14.0.0 and above.
  Note: OpsRamp recommends using the latest Gateway version for full coverage of recent bug fixes, enhancements, etc.

Supported Metrics

Default Monitoring Configurations

Zerto has default Global Device Management Policies, Global Templates, Global Monitors and Global Metrics in OpsRamp. You can customize these default monitoring configurations as per your business use cases by cloning respective Global Templates and Global Device Management Policies. We recommend doing this activity before installing the application to avoid noise alerts and data.

1. Default Global Device Management Policies

   You can find the Device Management Policy for each Native Type at Setup > Resources > Device Management Policies. Search with suggested name in global scope. Each Device Management Policy follows below naming convention:

   {appName nativeType - version}

   Ex: zerto Zerto Virtual Manager Local Site - 1 (i.e, appName = zerto, nativeType = Zerto Virtual Manager Local Site, version = 1)

2. Default Global Templates

   You can find the Global Templates for each Native Type at Setup > Monitoring > Templates. Search with suggested names in global scope. Each template follows below naming convention:

   {appName nativeType 'Template' - version}

   Ex: zerto Zerto Virtual Manager Local Site Template - 1 (i.e, appName = zerto, nativeType = Zerto Virtual Manager Local Site, version = 1)

3. Default Global Monitors

   You can find the Global Monitors for each Native Type at Setup > Monitoring > Monitors. Search with suggested name in global scope. Each Monitors follows below naming convention:

   {monitorKey appName nativeType - version}

   Ex: Zerto Virtual Manager Local Site Monitor zerto Zerto Virtual Manager Local Site 1 (i.e, monitorKey = Zerto Virtual Manager Local Site Monitor, appName = zerto, nativeType = Zerto Virtual Manager Local Site, version = 1)

Risks, Limitations & Assumptions

• Application can handle Critical/Recovery failure notifications for below two cases when user enables App Failure Notifications in configuration
  • Connectivity Exception
  • Authentication Exception
• The application will send duplicate/repeat failure alert notifications for every 6 hours.
• Application cannot control monitoring pause/resume actions based on above alerts Metrics can be used to monitor Zerto resources and can generate alerts based on the threshold values.
• We have provided 443 as default Port value for processing ZVM Rest APIs. Users can modify this value from the application configuration page at any point of time if required.
• Zerto Event/Alert polling will start only if the user enables Event/Alert Polling in configuration.
• Possible values of Alert Severity Filter configuration are Error, Warning.
• Default values of Help Identifier Filter configuration are ZVM0001, ZVM0002, ZVM0003, ZVM0004, etc.
• We have provided default mappings to map Zerto Severity with OpsRamp Severities as part of Alert Severity Mapping configuration. Users can modify them as per their use-case at any point of time from the application configuration page. Possible Severities are Critical, Warning, Ok, Info.
• We use GET /v1/alerts API for alerts polling functionality and below is the flow of execution:
  • For the first poll request, we consider the alerts which have is_dismissed=false and Alert Severity Filter, Help Identifier Filter and Alert Severity Mapping configuration details to parse and publish the critical/warning alerts and store those alert unique identifiers at app level to use them in further monitoring request processings.
  • From second polling onwards, application checks whether previously polled alerts are healed (i., is_dismissed=true) or not using current poll requests API response and create OK alerts for them accordingly.
  • The application checks whether any new alerts with is_dismissed=false are present in the current poll request’s API response and poll those critical/warning alerts and store the unique identifiers accordingly for further processings.
• No support of showing activity logs.
• The Template Applied Time will only be displayed if the collector profile (Classic and NextGen Gateway) is version 18.1.0 or higher.
• The minimum supported version for the option to get Latest snapshot metric is nextgen-14.0.0.
• Full discovery support requires gateway version 15.0.0 or above.
• Application is not compatible with Cluster Gateway.
