 As described in the [Azure TLS 1.2 migration announcement](https://azure.microsoft.com/updates/azuretls12/), Live Metrics now only supports TLS 1.2. If you are using an older version of TLS, Live Metrics will not display any data. For applications based on .NET Framework 4.5.1, refer to [How to enable Transport Layer Security (TLS) 1.2 on clients - Configuration Manager](/mem/configmgr/core/plan-design/security/enable-tls-1-2-client#bkmk_net) to support newer TLS version.
