Hi!

I did some changes because there was an issue when gelf4net couldn't reach graylog server....

Can you post your configuration

• bufferSize
• retryAfterMilliseconds
• httpClientTimeoutMilliseconds

Thanks

My AsyncGelfHttpAppender:

    <appender name="AsyncGelfHttpAppender" type="Gelf4Net.Appender.AsyncGelfHttpAppender, Gelf4Net">
        <url value="server" />
        <!-- Number of log lines to buffer for async send. Defaults to 10-->
        <bufferSize value="20" />
        <!-- Number of tasks to use for the async appender. 0 or fewer indicates one task per processor-->
        <threads value="2" />
        <layout type="Gelf4Net.Layout.GelfLayout, Gelf4Net">
            <param name="AdditionalFields" value="Application:AsyncHttpAppender,version:${version},envName:${cliente}, stringLevel:%level" />
            <param name="Facility" value="Solver-API" />
            <param name="IncludeLocationInformation" value="true" />
            <param name="SendTimeStampAsString" value="false" />
            <!--Sets the full_message and short_message to the specified pattern-->
            <!--<param name="ConversionPattern" value="[%t] %c{1} - %m" />-->
        </layout>
    </appender>

Hi,

Can you tell me more about the environment so I can reproduce it. The tests I did was to run the SimpleWebApplication and used NBomber and it didn't peak....

I'll try during the week with the settings

<bufferSize value="20" />
<threads value="2" />

thanks

LEt me try with your application and will return to you.

I've used your project and reproduced the error:

I've just used my log4net.config and problem appeared

Oki

I'll look into it during the week...

I really think is the <bufferSize value="20" />

Thanks :)

[thiagoloureiro]

Thank you! What value do you recommend using there? Somethiny bigger?
