My .NET Core 3 implementation of Quartz.Net is logging the following message approximately twice per minute and I would like to remove it without affecting my applications other logs:
"Batch acquisition of 0 triggers"
2020-06-22 17:42:24.745 +01:00 - [MyApplication] - [Debug] - [Quartz.Core.QuartzSchedulerThread] Batch acquisition of 0 triggers
2020-06-22 17:42:53.689 +01:00 - [MyApplication] - [Debug] - [Quartz.Core.QuartzSchedulerThread] Batch acquisition of 0 triggers
Where [MyApplication]
is populated by the Source
property and [Quartz.Core.QuartzSchedulerThread]
comes from the SourceContext
.
Quartz.net logs this automatically and I seem to have no control over deciding to log it or not. My logs are filling up too quickly.
My Appsettings.json file is as follows:
"Serilog": {
"IncludeScopes": false,
"MinimumLevel": {
"Default": "Debug",
"Override": {
"Microsoft": "Warning",
"System": "Warning"
}
},
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "C:/Logs/my-app.log",
"buffered": "true",
"flushToDiskInterval": "00:00:10",
"rollingInterval": "Infinite",
"rollOnFileSizeLimit": "true",
"fileSizeLimitBytes": 10485760,
"retainedFileCountLimit": 90,
"outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} - {Source} - [{Level}] - [{SourceContext}] {Message}{NewLine}{Exception}"
}
},
{
"Name": "Async",
"Args": {
"restrictedToMinimumLevel": "Information",
"configure": [
{
"Name": "Console",
"Args": {
"outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} - {Source} - [{Level}] - {Message}{NewLine}{Exception}"
}
}
]
}
}
]
}
My Program.cs main
initially configures the logger like this:
Log.Logger = new LoggerConfiguration()
.ReadFrom.Configuration(configuration)
.Enrich.FromLogContext()
// set Source property, which we use in output formatting, to the name of the application
.Enrich.WithProperty("Source", value: "MyApplication")
.CreateLogger();
And later in my Startup.cs, when my services & settings have been registered Serilog is reconfigured as follows:
public void Configure(IApplicationLifetime applicationLifetime)
{
SerilogLogger.Reconfigure(
applicationName: "MyApplication",
toFixedFile: !string.IsNullOrEmpty(_loggerSettings.LogFilePathFixed),
fileName: _loggerSettings.LogFilePathFixed,
fileSizeBytes: configuredLogFileSize * 1024 * 1024,
minimalLevel: "Debug",
outputTemplate: _loggerSettings.LogFormat);
}
Where the Reconfigure
extension method comes from a 3rd party dll built in another development department.
I have tried to add the following after the invocation of Reconfigure
:
SerilogLogger.RefineConfiguration(x => x.MinimumLevel.Override("Quartz", LogEventLevel.Warning));
But it doesn't work because the actual source is MyApplication
, and if I use "MyApplication" instead of "Quartz" I suppress all debug and information logs for the entire application.
Any ideas? With code examples please.
I have implemented a solution for this problem, there were two parts to the solution:
1 - As pointed out to me in the Quartz google groups, I was missing the following Serilog configuration from appsettings.json to define the correct logging level for Quartz:
"MinimumLevel": {
"Default": "Debug",
"Override": {
"Microsoft": "Warning",
"System": "Warning",
"Quartz": "Warning"
}
},
The configuration of "Quartz": "Warning"
suppressed the Debug
"Batch acquisition" messages from being logged.
And
2 - The invocation of both the SerilogLogger.Reconfigure
and SerilogLogger.RefineConfiguration
methods was completely unnecessary. I removed this. It was overwriting the config from point 1) above. All Serilog configuration should take place in my appsettings.
