IIS Event Monitoring

[aspdaddy]

I have written this code below to trap application errors in IIS, (EntryWrittenEventHandler sends me email for certain types of errors etc) problem is its a form app & it needs re-writing as a service which is quite complex.

Does anyone know an easier way to be sent emails on certain events

InitializeComponent();
EventLog log = new EventLog("Application");
log.EntryWritten += new EntryWrittenEventHandler(log_EntryWritten);
log.EnableRaisingEvents = true;

You could do something similar with Global.asax and the following event global handler for the application. (the one I listed saves to a file not to email, but should give you enough of an idea to make it work).

 protected void Application_Error(object sender, EventArgs e)
 {
  System.Exception lastError = this.Server.GetLastError().GetBaseException();

  string filepath = this.Context.Request.MapPath("/App_Data/Error-") + System.IO.Path.GetRandomFileName() + ".txt";

  //Just dumping the Error to a attachment.
  System.IO.StreamWriter writer = new System.IO.StreamWriter(filepath);
  writer.WriteLine(System.DateTime.Now.ToLongDateString());
  writer.WriteLine();
  writer.Write(lastError.ToString());
  writer.WriteLine();
  writer.WriteLine(this.Request.Url.ToString());
  writer.WriteLine("UserAgent = {0}{1}", this.Context.Request.UserAgent, System.Environment.NewLine);
  writer.WriteLine("UserHostAddress = {0}{1}", this.Context.Request.UserHostAddress, System.Environment.NewLine);

  if (this.Context.Request.ServerVariables.Count > 0)
  {
  writer.WriteLine("{0}{0}ServerVariables Collection{0}", System.Environment.NewLine);
  for (int i = 0;i <= this.Context.Request.ServerVariables.Count - 1;i++)
  {
   writer.WriteLine("{0} = {1}{2}", this.Context.Request.ServerVariables.GetKey(i), this.Context.Request.ServerVariables[i], System.Environment.NewLine);
  }
  }

  if (this.Context.Request.Headers.Count > 0)
  {
  writer.WriteLine("{0}{0}Headers Collection{0}", System.Environment.NewLine);
  for (int i = 0;i <= this.Context.Request.Headers.Count - 1;i++)
  {
   writer.WriteLine("{0} = {1}{2}", this.Context.Request.Headers.GetKey(i), this.Context.Request.Headers[i], System.Environment.NewLine);
  }
  }

  if (this.Context.Request.QueryString.Count > 0)
  {
  writer.WriteLine("{0}{0}QueryString Collection{0}", System.Environment.NewLine);
  for (int i = 0;i <= this.Context.Request.QueryString.Count - 1;i++)
  {
   writer.WriteLine("{0} = {1}{2}", this.Context.Request.QueryString.GetKey(i), this.Context.Request.QueryString[i], System.Environment.NewLine);
  }
  }

  if (this.Context.Request.Form.Count > 0)
  {
  writer.WriteLine("{0}Form Collection{0}", System.Environment.NewLine);
  foreach (string Key in this.Request.Form.Keys)
  {
   writer.WriteLine("{0} = {1}{2}", Key, this.Request.Form[Key], System.Environment.NewLine);
  }
  }
  if (this.Context.Request.Cookies.Count > 0)
  {
  writer.WriteLine("{0}Cookies Collection{0}", System.Environment.NewLine);
  foreach (string Key in this.Request.Cookies.Keys)
  {
   writer.WriteLine("{0} = {1}{2}", Key, this.Request.Cookies[Key].Values, System.Environment.NewLine);
  }
  }
  writer.Flush();
  writer.Close();
 }
