New customer installation

Return to top

Use the Orion Installer, available in the Customer Portal, to install SAM. See the Orion Platform Products Installation and Upgrade Guide for details. After installation, see the SAM Getting Started Guide to learn about configuring and customizing SAM.

Before you upgrade

To prepare for the upgrade:

  1. Read these Release Notes.
  2. Confirm that all servers comply with SAM 2020.2 System Requirements.
  3. (Optional) Back up any custom code, such as modified SolarWinds .css files or added .js files. Click here for tips.

If upgrading from a previous version, note the following details:

  • The Orion Log Viewer (OLV) replaces the legacy Syslog and Trap Viewers.
  • To collect trust data for Global Catalog (GC) servers, AppInsight for Active Directory uses port 3268. If a GC domain controller uses port 3269 instead, update that setting in the application monitor assigned to the node. See Configure AppInsight for Active Directory on nodes.
  • The Application Dependencies feature is disabled during upgrades to prevent performance issues in large environments. To restart polling later, enable the Application Dependencies feature.
  • If you exceed recommended cloud monitoring limits and receive a 503 Service Unavailable error when adding Azure accounts, click here for a workaround.
  • To monitor Exchange Server 2016 and later, install PowerShell 2.0 or later and provide local Administrator rights. See Using PowerShell in SAM.
  • If monitoring containers in your SAM environment:
    • Rebuild containers after upgrading and then add them back. Click here for details.
    • The Kubernetes script included in the Orion Platform was updated for Kubernetes v1.16. If you need a script designed for an earlier Kubernetes version, see this Success Center article.
  • If you upgrade to a localized version of SAM, all templates with new versions that support localization will be replaced. Back up any SAM templates and application monitors modified with custom changes. You cannot roll back to English after installing the Orion Platform in another language.
  • Due to end-of-support by Microsoft for Basic Authentication connections to Exchange Online APIs, the following templates were deprecated in SAM 2020.2. Consider using API poller templates designed for Microsoft 365 instead, as described in the SAM API Poller Template Guide.

    • Microsoft Office 365 Exchange Online
    • Microsoft Office 365 Mobile Device Management
    • Microsoft Office 365 Portal
    • Microsoft Office 365 Subscription
  • The following Citrix templates were deprecated in SAM 2020.2 but are still available in THWACK. Click here for the latest Citrix templates, including the Citrix Hypervisor template that replaces the Citrix XenServer template.
    • Citrix PVS Accelerator for XenServer
    • Citrix XenApp 5.0 Core WMI Counters
    • Citrix XenApp 5.0 ICA Session WMI Counters
    • Citrix XenApp 5.0 Presentation Server WMI Counters
    • Citrix XenApp 5.0 Services
    • Citrix XenServer
  • The following templates were deprecated in SAM 2020.2.1 but are still available in THWACK. Use AppInsight for SQL to monitor the NTA Flow Storage Database instead.
    • SolarWinds NetFlow Traffic Analyzer Database
    • SolarWinds NetFlow Traffic Analyzer
  • The Orion Server 2017.3 and SolarWinds Failover Engine templates were replaced by Orion Server 2020.2 templates. Deprecated templates remain in THWACK and legacy SAM 2017.3 — 2019.4 installations.

SolarWinds recommends checking THWACK periodically for updates to SAM's out-of-the-box (OOTB) templates. Apart from AppInsight templates, SAM doesn't update templates automatically during upgrades to avoid overwriting custom changes you may have made. For details, see Import and export SAM templates.

How to upgrade

Starting with SAM 6.9, you can upgrade SAM directly from the Orion Web Console (Settings > My Orion Deployment). Downloading the Orion Installer is no longer necessary.

Known issues

Return to top

Days Remaining value in SSL Certificate Expiration and IIS SSL Certificate Expiration Report widgets are not updated for AppInsight for IIS.

Issue: Polling only occurs once — when AppInsight for IIS is assigned to a node — but does not continue.

Workaround: Assign the SSL Certificate Expiration Date Monitor template to the IIS node to update the SSL date daily. Click here for details.

Component monitor scripts in the AIX template do not execute if "Inherit credentials from node" is selected.

Issue: Header issues in Perl script output prevent component monitors from inheriting credentials from nodes, so scripts fail. This may impact CPU statistic, Paging statistic/sec, Percentage of using system devices, Disk operations/sec of system devices, and Top 10 active processes metrics.

Workaround: Edit component monitors to provide credentials, or avoid using "Inherit credentials from node" option for affected component monitors. Click here for details.

Application Dependency polling fails; dependencies or connections between nodes for Windows Server and other applications do not appear as expected.

Issue: Rows in the dbo.AgentManagement_Agents table that share the same Node ID may cause exceptions.

Workaround: Uninstall agents from nodes, remove duplicate rows in the database, and then reinstall agents. Click here for details.

Some SAM pages and widgets are not compatible with Internet Explorer (IE) 11.

Issue: Warning messages may appear when using IE 11 with features introduced in SAM 2020.2. SolarWinds recommends using a different browser (such as Chrome, Firefox, or Microsoft Edge) for the best SAM experience.

Inconsistencies in SAM SQL tables

Issue: After upgrading to SAM 6.9 or later, a known Microsoft issue may create inconsistency in SQL tables, as indicated by a Database Integrity Check message.

Workaround: Back up the Orion database and execute a SQL query provided here.

Windows Scheduled Tasks Monitor (WSTM) polling fails for Active Directory nodes with UPN-formatted credentials.

Issue: If you add the Windows Scheduled Tasks Monitor to an Active Directory node with User Principal Name (UPN) credentials (for example, user@domain.tld, instead of domain.tld\user), polling fails, an "Access is denied" error appears in the Windows Scheduled Tasks widget, and errors appear in logs.

Workaround: Use the down-level logon name format (domain\user) instead of UPN format (user@domain). Click here for details.

High memory utilization for SolarWinds.ServiceHost.Process slows Active Directory (AD) servers monitored by Orion agents.

Issue: The ServiceDirectoryClient component leaks Service Directory client connections due to exceptions that occur when opening the channel.

Workaround: Upgrade to the latest release of SAM or switch polling method for AD servers. Click here for details.

Microsoft Windows Server 2008 R2-2012 R2 Failover Cluster (Advanced) template fails with errors and node status switches to Down.

Issue: The 64-bit FailoverClusters module conflicts with PowerShell bitness so polling fails.

Workaround: Modify a script included in the templates; click here for details.

Warranty data does not appear after Asset Inventory polling of HPE Proliant servers.

Issue: API-related changes to HP Warranty servers interrupt periodic polling. No workaround is currently available. Click here for details.

SolarWinds recommends using the Orion agent for Linux to monitor Wildfly (formerly JBoss) systems. However, note that the JMX bridge can be configured to monitor WildFly or JBoss targets, but not both types simultaneously.

Issue: WildFly, formerly known as JBoss, is an application server developed by Red Hat. For details, see Configure JMX monitoring on WildFly servers.

Application dependency polling is not supported on target Linux systems that use GNU C Library (glibc) 2.17 or earlier.

Issue: As described here, SAM deploys agent plug-ins to target systems to monitor application connections. Plug-ins deployed by SAM 2020.2 and 2020.2.1 include an Nping executable binary that doesn't support distributions based on glibc 2.17 or earlier, such as CentOS and Red Hat Enterprise Linux (RHEL) 6. As a workaround, update Linux distributions on target systems. SolarWinds recommends testing in an experimental OS first.

Applications hosted on Windows 2008 R2 servers switch to Unknown state after upgrading to SAM 2020.2.

Issue: This issue occurs if SAM cannot locate a referenced assembly in the Global Assembly Cache (GAC). Click here for workarounds.

AppInsight for Active Directory stops polling after upgrade to SAM 2020.2.

Issue: If AppInsight for Active Directory stops working and an "Unable to start polling" message appears on the AppInsight for Active Directory Details page, make sure the version of .NET Framework on target nodes matches the version on the Orion server. SAM 2020.2 uses .NET 4.8. Click here for details.

AppInsight for IIS polling on Windows Server 2008 nodes may cause WinRMFeatureService errors in logs.

Issue: Starting in SAM 2020.2, WinRM is the default transport method to collect data for WMI-based component monitors. When monitoring Windows Server 2008 nodes with AppInsight for IIS, the following message may appear in application logs:

{{ERROR SolarWinds.APM.Probes.Management.WinRmFeatureService - Windows version 6.1.7601 with SP 1 does not support InvokeMethod }}.

The default log location is C:\ProgramData\SolarWinds\Logs\APM\ApplicationLogs.

This message appears because the WinRM Invoke method is not supported by Windows Server 2008, but fallback should still occur and IIS servers will be polled.

AppInsight for IIS polling on Windows Server 2008 R2 SP1 nodes fails and applications switch to Unknown state.

Issue: Windows Server .NET 4.8 agents expect a later version of PowerShell, resulting SolarWinds.APM.Probes.CustomWmiProbe- and Microsoft.Management.Infrastructure-related errors in logfiles.

Workaround: Install PowerShell 3.0 or later on target servers. Click here for details.
