In het volgende codevoorbeeld ziet u een aangepaste implementatie van de CanFire methode.

// Implements the IWebEventCustomEvaluator.CanFire 
// method. It is called by the ASP.NET if this custom
// type is configured in the profile
// element of the healthMonitoring section.
public bool CanFire(
    System.Web.Management.WebBaseEvent e, 
    RuleFiringRecord rule)
{

    bool fireEvent;
    string lastFired = rule.LastFired.ToString();
    string timesRaised = rule.TimesRaised.ToString();

    // Fire every other event raised.
    fireEvent =
        (rule.TimesRaised % 2 == 0) ? true : false;

    if (fireEvent)
    {
        firingRecordInfo =
            string.Format("Event last fired: {0}",
            lastFired) +
            string.Format(". Times raised: {0}",
