.NET agent release notesRSS

Notice: For the new application logging features, if you install using the MSI, please update to version 9.7.1 or later.

Notice: If using Microsoft.Extensions.Logging as your logging framework of choice, please use .NET agent version 10.1.0 or newer. We encourage you to adopt the newer version due to bug #1230, which we fixed in #1237, that was resolved in .NET agent version 10.1.0.

New Features

• Adds support for logging metrics which shows the rate of log message by severity in the Logs chart in the APM Summary view for Log4net, Serilog, and Microsoft.Extensions.Logging. This is enabled by default in this release. (#1034)
• Adds support for forwarding application logs to New Relic. This automatically sends enriched application logs for Log4net, Serilog, and Microsoft.Extensions.Logging. This is disabled by default in this release. (#1034)
• Adds support for enriching application logs written to disk or standard out for Log4net, Serilog, Microsoft.Extensions.Logging. This can be used with another log forwarder if in-agent log forwarding is not desired. We recommend enabling either log forwarding or local log decorating, but not both features. This is disabled by default in this release. To learn more about APM logs in context and the configuration options, please see the documentation here. (#1034)
• Adds flexibility to what is accepted to enable/disable boolean environment variables per FR #1008. "0"/"1", and case insensitive "true"/"false" are now accepted. (#1033)

Fixes

• Adds a new environment variable NEW_RELIC_DISABLE_APPDOMAIN_CACHING for customers to try when experiencing #533 high lock contention related to AppDomain.GetData() usage by the agent when profiling .NET Framework applications. (#1033)

• The scriptable installers are now deprecated and will be removed from the download site in a future major release. (Issue: #571)
