Is it possible to add fore ground and back ground to any app that is down?

samflex

Greetings again, Sorry that I have to come back for help for this script. Each time this script runs, it sends email notifications to our Executive team advising them of whether any or all of the apps are either down or up. The script works very well thanks entirely to the great Richard Deeming. However, management has asked that I modify the script to add foreground color of red and background color of yellow to any URL of the app that is down along with the text indicating down. For instance, when app sends out email notifications, it lists the apps and their status as follows: Please find the status of the DMZ servers below: https://www.link1: WORKING https://www.link2.com WORKING https://www.link3.com DOWN https://www.link4.com WORKING They would like any app that is down to display as follows: Please find the status of the DMZ servers below: link 1: https://www.link1 WORKING Link 2 https://www.link2.com WORKING Link 3 https://www.link3.com DOWN Link 4 https://www.link4.com WORKING In this example, Link 3 https://www.link3.com DOWN They would like the entire row of the URL that is down to be color coded, background color of yellow and text color of red. Link 1 corresponds to the first URL, Link 2 to second URL, etc. If it is only possible to just color code just the URL and the DOWN text without the link #, that would be fine too. I am not sure if this is possible. I could not figure a way to do this. Any thought on how I could get this to work? I recognize the send mail bit has body (IsBodyHtml) set to false but I can change this to true if I can the color thing to work. Below is the working code.

You would need to format the message body as HTML.

static async Task SendEmailAsync(string subject, string body, bool isBodyHtml = false)
{
using MailMessage mm = new(ConfigurationManager.AppSettings["FromEmail"], "joeblow@gmail.com");
mm.To.Add("janeblow@yahoo.com");
mm.CC.Add("kevin.bruiner@hotmail.com");
mm.Subject = subject;
mm.Body = body;
mm.IsBodyHtml = isBodyHtml;

SmtpClient smtp = new()
{
    Host = ConfigurationManager.AppSettings\["Host"\],
    Port = int.Parse(ConfigurationManager.AppSettings\["Port"\]),
    EnableSsl = true,
    UseDefaultCredentials = false,
    Credentials = new NetworkCredential(ConfigurationManager.AppSettings\["Username"\], ConfigurationManager.AppSettings\["Password"\]),
};

await smtp.SendMailAsync(mm);

}

static async Task Main(string[] args)
{
System.Collections.Concurrent.ConcurrentDictionary urlToStatus = new();

IEnumerable<Task<bool>> tasks = args.Select(async url =>
{
    bool result = await ServerStatusByAsync(url);
    return urlToStatus.TryAdd(url, result);
});

bool\[\] results = await Task.WhenAll(tasks);

StringBuilder body = new("<p>Please find the status of the DMZ servers below:</p>");
body.Append("<ul>");
foreach (var kvp in urlToStatus)
{
    string encodedLink = System.Net.WebUtility.HtmlEncode(kvp.Key);
    
    body.Append(kvp.Value ? "<li>" : "<li style=\\"color:red;background-color:yellow;\\">");
    body.Append(kvp.Value ? "<a href=\\"" : "<a style=\\"color:red;\\" href=\\"");
    body.Append(encodedLink);
    body.Append("\\">");
    body.Append(encodedLink);
    body.Append("</a> - ");
    body.Append(kvp.Value ? "WORKING" : "DOWN");
    body.Append("</li>");
}
body.Append("</ul>");

await SendEmailAsync("DMZ Server Status", body.ToString(), true);
await Task.Delay(3000);

// Return the number of servers which were down:
return results.Count(result => !result);

}

Oh wow, this is so incredible. Just too good. Many, many THANK YOU sir. I truly do appreciate your help. You are the nicest, most generous individual that I never met. Sir, do you know why they keep getting two different emails? Let's say for instance that they just wanted to get the status of one link, https://www.link1.com When they receive email, it displays like this: DMZ Server Status. Please find the status of the DMZ servers below. https://www.link1.com WORKING GET https://www.link1.com" returned OK Is there a way to remove the second email so they always get the bolded one with subject DMZ Server Status and when they open the email, they get details about the link or links? UPDATE: I *THINK* I got it! This is the part of the script that is sending the GET email ( the second email)

    static async Task ServerStatusByAsync(string url)
    {
        HttpClient http = new();
        using (HttpResponseMessage response = await http.GetAsync(url))
        {
            Console.WriteLine("GET {0}: {1}", url, response.StatusCode);

            if (response.IsSuccessStatusCode)
            {
              //  await SendEmailAsync($"{url} WORKING", $"GET {url} returned {response.StatusCode}");
                return true;
            }
           // await SendEmailAsync($"{url} DOWN", $"GET {url} returned {response.StatusCode}");
            return false;
        }
    }

So by commenting out

await SendEmailAsync(...)

for both WORKING and DOWN, allows only one email: DMZ Server Status... to come through. I hope it is correct. If so, all I would need help on now is to create another copy of this same script but this time, to send email to certain group ONLY when any or all of the apps is(are) down and I swear no more changes will be needed.

Richard Deeming

That's the correct change to remove the other email. If you only want to send the main email if any site is down, you'll need to check before sending it:

bool[] results = await Task.WhenAll(tasks);
if (results.Any(up => !up))
{
StringBuilder body = ...
...
await SendEmailAsync("DMZ Server Status", body.ToString(), true);
await Task.Delay(3000);
}

If you only want to send the message if all sites are down, use:

if (results.All(up => !up))
