Couple ways to log to event log, then we can use simple filtering and alerts in EvtViewer to create a quick and dirty notification sub-system in case we dont have time to
implement notifications in an app or we are using an existing app such as a COTS product,
See here
Log to Event Log using:
CMD
using eventcreate:
eventcreate /ID 755 /L APPLICATION /T INFORMATION /SO BACKUP /D "My first log"
C# System.Diagnostics
System.Diagnostics.EventLog.WriteEntry(source,
message,
ConvertTraceType(type),
eventId);
c# MS App Blocks
Logger.Write(message, LogSources.CheckSource(source), Priority.Normal, eventId, type, title, dictionary);
Logger.Write(ex, LogSources.DefaultSource(), Priority.High,
eventid, TraceEventType.Error, title , dictionary);
PS check source, create
if ([System.Diagnostics.EventLog]::SourceExists($mysource) -eq $false) {
[System.Diagnostics.EventLog]::CreateEventSource($mysource, "Application")
}
PS log
Write-EventLog -LogName "Application" -Source $mysource -EntryType Information -EventID 100 -Message "Start logging!"
Write-EventLog –LogName Application –Source “My Script” –EntryType Information –EventID 1
–Message “This is a test message.”
WMI
strEventDescription = "Payroll application could not be installed on " _
& objNetwork.UserDomain & "\" & objNetwork.ComputerName _
& " by user " & objNetwork.UserName & _
". Free space on each drive is: " & strDriveSpace
objShell.LogEvent EVENT_FAILED, strEventDescription
SQL (T-SQL)
DECLARE @msg VARCHAR(100)
SELECT @msg = ERROR_Message()
RAISERROR(@msg, 11, 1) WITH LOG
-- OR
USE master;
EXEC xp_logevent 60000, @@MESSAGE, informational
C# Ent Logging Detail:
public void EntLoggingTest03()
{
try
{
LogEntry entry = new LogEntry();
//entry.ActivityIdString = "ActivityIdString";
entry.AppDomainName = "AppDomainName";
//entry.Categories.Add("DTech Data Services NOC Services");
entry.Categories.Add(SOURCE);
//entry.ErrorMessages = "ErrorMessages";
entry.EventId = (int)LogEventID.FileRouterEventID.FileRouterError;
Dictionary<string, object> dictionary = new Dictionary<string, object>();
dictionary.Add("ZipFile", "1.zip");
dictionary.Add("ZipURI", @"C:\Tamepo");
entry.ExtendedProperties = dictionary;
//entry.LoggedSeverity = "LoggedSeverity";
entry.MachineName = "Me";
entry.Message = "a msg";
entry.Priority = 1;
entry.ProcessName = "DTech.Util.Data.Test?";
entry.Severity = TraceEventType.Warning;
Logger.Write(entry);
// throw new ArgumentException("InsertEventLogErrorTest00 EXCEPTION");
