Synopsis

dotnet-monitor [-h|--help] [--version] <command>

Description

The dotnet-monitor global tool is a way to monitor .NET applications in production environments and to collect diagnostic artifacts (for example, dumps, traces, logs, and metrics) on-demand or using automated rules for collecting under specified conditions.

Options

  • --version

    Displays the version of the dotnet-monitor utility.

  • -h|--help

    Shows command-line help.

Commands

Command
dotnet monitor collect
dotnet monitor config show
dotnet monitor generatekey

dotnet-monitor collect

Monitor .NET applications, allow collecting diagnostic artifacts, and send the results to a chosen destination.

Synopsis

dotnet-monitor collect [-h|--help] [-u|--urls] [-m|--metrics] [--metricUrls] [--diagnostic-port] [--no-auth] [--temp-apikey] [--no-http-egress]

Options

  • -h|--help

    Shows command-line help.

  • -u|--urls <urls>

    Bindings for the HTTP api. Default is https://localhost:52323.

  • -m|--metrics [true|false]

    Enable publishing of metrics to /metrics route. Default is true

  • --metricUrls <urls>

    Bindings for the metrics HTTP api. Default is http://localhost:52325.

  • --diagnostic-port <path>

    The fully qualified path and filename of the diagnostic port to which runtime instances can connect. Specifying this option places dotnet-monitor into 'listen' mode. When not specified, dotnet-monitor is in 'connect' mode.

    On Windows, this must be a valid named pipe name. On Linux and macOS, this must be a valid Unix Domain Socket path.

  • --no-auth

    Disables API key authentication. Default is false.

    It is strongly recommended that this option is not used in production environments.

  • --temp-apikey

    Generates a temporary API key for the dotnet-monitor instance.

  • --no-http-egress

    Disables egress of diagnostic artifacts via the HTTP response. When specified, artifacts must be egressed using an egress provider.

dotnet-monitor config show

Shows configuration, as if dotnet-monitor collect was executed with these parameters.

Synopsis

dotnet-monitor config show [-h|--help] [-u|--urls] [-m|--metrics] [--metricUrls] [--diagnostic-port] [--no-auth] [--temp-apikey] [--no-http-egress] [--level] [--show-sources]

Options

  • -h|--help

    Shows command-line help.

  • -u|--urls <urls>

    Bindings for the HTTP api. Default is https://localhost:52323.

    This value is mapped into configuration as the urls key.

  • -m|--metrics [true|false]

    Enable publishing of metrics to /metrics route. Default is true.

    This value is mapped into configuration as the Metrics:Enabled key.

  • --metricUrls <urls>

    Bindings for the metrics HTTP api. Default is http://localhost:52325.

    This value is mapped into configuration as the Metrics:Endpoints key.

  • --diagnostic-port <path>

    The fully qualified path and filename of the diagnostic port to which runtime instances can connect. Specifying this option places dotnet-monitor into 'listen' mode. When not specified, dotnet-monitor is in 'connect' mode.

    On Windows, this must be a valid named pipe name. On Linux and macOS, this must be a valid Unix Domain Socket path.

    This value is mapped into configuration as the DiagnosticPort:EndpointName key.

  • --no-auth

    Disables API key authentication. Default is false.

    It is strongly recommended that this option is not used in production environments.

    This value is not mapped into configuration.

  • --temp-apikey

    Generates a temporary API key for the dotnet-monitor instance.

    This value is mapped into configuration as the Authentication:MonitorApiKey key.

  • --no-http-egress

    Disables egress of diagnostic artifacts via the HTTP response. When specified, artifacts must be egressed using an egress provider.

    This value is not mapped into configuration.

  • --level

    Configuration level. Full configuration can show sensitive information. There are two levels:

    • Full - The full configuration without any redaction of any values.
    • Redacted - The full configuration but sensitive information, such as known secrets, is redacted.

  • --show-sources

    Identifies from which configuration source each effective configuration value is provided.

dotnet-monitor generatekey

Generate an API key and hash for HTTP authentication.

Synopsis

dotnet-monitor generatekey [-h|--help] [-o|--output]

Options

  • -h|--help

    Shows command-line help.

  • -o|--output <Cmd|Json|MachineJson|PowerShell|Shell|Text>

    The output format in which the API key information is written to standard output.

    The allowable values are:

    • Cmd - Outputs in a format usable in Windows Command Prompt or batch files.
    • Json - Outputs in a format of a JSON object.
    • MachineJson - Outputs in a format of a JSON object without comments and explanation. Useful for automation scenarios.
    • PowerShell - Outputs in a format usable in PowerShell prompts and scripts.
    • Shell - Outputs in a format usable in Linux shells such as Bash.
    • Text - Outputs in a format that is plain text.
