.net health monitoring

This is a little blurb I use almost everywhere for almost everything that will log all sorts of useful info about a .net app in the application log. It will grab unhandled exceptions as well as application lifetime events (app pool or domain restarts, etc.) This is a really good one to use when your devs won’t add this to the code themselves! It will work (or has for me) straight up in any .net code. All you do is place this in the web.config.

<healthMonitoring enabled="true">

      <eventMappings>

        <clear />

        <!– Log ALL error events –>

        <add name="All Errors" type="System.Web.Management.WebBaseErrorEvent" startEventCode="0" endEventCode="2147483647" />

        <!– Log application startup/shutdown events –>

        <add name="Application Lifetime Events" type="System.Web.Management.WebApplicationLifetimeEvent" startEventCode="0" endEventCode="2147483647"/>

      </eventMappings>

      <rules>

        <clear />

        <add name="Application Events" eventName="Application Lifetime Events" provider="EventLogProvider" profile="Default" minInstances="1" maxLimit="Infinite" minInterval="00:01:00" custom="" />

        <add name="All Errors Default" eventName="All Errors" provider="EventLogProvider" profile="Default" minInstances="1" maxLimit="Infinite" minInterval="00:00:00" />

      </rules>

    </healthMonitoring>
