监控，为服务保驾护航，也为业务量化提供有力支持，当然在SemanticKernel中的监控也不例外，同时还能为真金白银的Token提供量化监控。
下面是项目中使用的Nuget包：
<ItemGroup> <PackageReference Include="Microsoft.SemanticKernel" Version="1.7.1" /> <PackageReference Include="NAudio" Version="2.2.1" /> <PackageReference Include="OpenTelemetry" Version="1.8.1" /> <PackageReference Include="OpenTelemetry.Exporter.Prometheus.HttpListener" Version="1.8.0-rc.1" /> <PackageReference Include="OpenTelemetry.Instrumentation.AspNetCore" Version="1.8.1" /></ItemGroup>
添加PrometheusHttpListener监控插件：
var meterProvider = Sdk.CreateMeterProviderBuilder() .AddMeter("Microsoft.SemanticKernel*") .AddPrometheusHttpListener(options => options.UriPrefixes = new string[] { "http://localhost:9465/" }) .Build();
接下来就是下载Prometheus，修改prometheus.yml配置如下：
scrape_configs: - job_name: "prometheus" static_configs: - targets: ["localhost:9090"] - job_name: "AI" scrape_interval: 1s # poll very quickly for a more responsive demo static_configs: - targets: ["localhost:9465"]
然后再下载Grafana，配置数据源为Prometheus，然后分别配置展示：
