Answer 1

using DotNetNuke.Common.Utilities;
using DotNetNuke.Services.Log.EventLog;
public static void DnnEventLogMsg(string msg)
{
    EventLogController eventLog = new EventLogController();
    DotNetNuke.Services.Log.EventLog.LogInfo logInfo = new LogInfo();
    PortalSettings ps = PortalController.Instance.GetCurrentPortalSettings();
    UserInfo userInfo = UserController.Instance.GetCurrentUserInfo();
    logInfo.LogUserID = userInfo.UserID;
    logInfo.LogPortalID = ps.PortalId;
    logInfo.LogTypeKey = EventLogController.EventLogType.ADMIN_ALERT.ToString();
    logInfo.AddProperty("Atena3 Message", msg);
    eventLog.AddLog(logInfo);
}

Also, if you want to add more data to the log, you can use LogInfo class to add events to the log.

Dim eventLog As EventLogController
eventLog = New EventLogController()

Dim logInfo As DotNetNuke.Services.Log.EventLog.LogInfo
logInfo = New LogInfo()
logInfo.LogUserID = UserId
logInfo.LogPortalID = PortalSettings.PortalId
logInfo.LogTypeKey = EventLogController.EventLogType.ADMIN_ALERT.ToString()
logInfo.AddProperty("PropertyName1", propertyValue1)
logInfo.AddProperty("PropertyName2", propertyValue2)

eventLog.AddLog(logInfo)

From http://www.ventrian.com/Resources/Articles/tabid/213/articleType/ArticleView/articleId/330/Logging-to-the-EventLog.aspx (just the relevant part of the article):

Using the event log in code is quite simple, the code is as follows:-

First, create an instance of the EventLogViewer...

Dim objEventLog As New DotNetNuke.Services.Log.EventLog.EventLogController

Next, log the event you wish to trap...

objEventLog.AddLog("Sample Message",
    "Something Interesting Happened!",
    PortalSettings,
    -1,
    DotNetNuke.Services.Log.EventLog.EventLogController.EventLogType.ADMIN_ALERT)

Now, when this code is run, the event log entry should appear in admin -> log viewer! You can customise these type of events, whether they be admin, host, item updated, etc.

This is the C# version

using DotNetNuke.Common.Utilities;
using DotNetNuke.Services.Log.EventLog;

EventLogController eventLog = new EventLogController();
DotNetNuke.Services.Log.EventLog.LogInfo logInfo = new LogInfo();
logInfo.LogUserID = UserId;
logInfo.LogPortalID = PortalSettings.PortalId;
logInfo.LogTypeKey=EventLogController.EventLogType.ADMIN_ALERT.ToString();
logInfo.AddProperty("KeyWord=", txtSearch.Text.Trim());
logInfo.AddProperty("KeyWordLike=", myParams);
eventLog.AddLog(logInfo);
