如何在systemd运行的.NET 8.0应用中禁用InfluxDB日志刷屏journalctl

我在.NET 8.0 Worker应用中使用InfluxDB.Client，本地通过dotnet run运行时不会产生下述日志，但编译为自包含程序并通过systemd在控制器上运行时，每次向InfluxDB发送数据都会生成大量重复日志，填满journalctl：

Sep 04 02:52:12 compulab-imx8mp TSLogger[1138]: Flushing batches before shutdown.
Sep 04 02:52:12 compulab-imx8mp TSLogger[1138]: The data was successfully written to InfluxDB 2.
Sep 04 02:52:12 compulab-imx8mp TSLogger[1138]: The batch item: OnNext(RestSharp.RestResponse) was processed successfully.
Sep 04 02:52:12 compulab-imx8mp TSLogger[1138]: The WriteApi was disposed.
Sep 04 02:52:12 compulab-imx8mp TSLogger[1138]: The data was successfully written to InfluxDB 2.
Sep 04 02:52:12 compulab-imx8mp TSLogger[1138]: The batch item: OnNext(RestSharp.RestResponse) was processed successfully.

InfluxDB操作代码（C#） #

string tokenInfluxDb = cabinetConfig.InfluxDb.Token;
string urlInfluxDb = cabinetConfig.InfluxDb.Url;
string org = cabinetConfig.InfluxDb.Org;
string bucket = cabinetConfig.InfluxDb.Bucket;

clientInfluxDb = new InfluxDBClient(urlInfluxDb, tokenInfluxDb);

var point = PointData
    .Measurement(item.Cage)
    .Field(item.MeasurementId, value)
    .Tag("sn", item.SerialNumber)
    .Timestamp(DateTime.UtcNow, WritePrecision.Ns);

LogToDb(point);

async void LogToDb(PointData point)
{
    using (var writeApi = clientInfluxDb.GetWriteApi())
    {
        writeApi.WritePoint(point, bucket, org);
    }
}

Worker.csproj配置 #

<TargetFramework>net8.0</TargetFramework>
<PackageReference Include="InfluxDB.Client" Version="4.14.0" />

systemd服务文件 #

[Unit]
Description=InfluxDBWorker

[Service]
ExecStartPre=/bin/sleep 30
WorkingDirectory=/home/usr/application/InfluxDBWorker

KillSignal=SIGINT
SyslogIdentifier=InfluxDBWorker

已尝试的无效操作 #

• 在环境变量和appsettings.json中设置日志级别为Warning
• 在journald.conf中配置ForwardToConsole=no
• 查阅过InfluxDB.Client相关问题但未解决
