Hello people,
Good night!
In this post I will demonstrate how to validate by SQL Server if a server is responding to the network using CLR (C #) and the PING class, which simulates a ping request that you make at the DOS prompt in Windows or in the Unix Shell.
In everyday life, I use this function a lot to check if a file-sharing server, for example, is available to write database routine files. Otherwise, I can have my routine trigger an email or even write these files to another directory. We can use this function to create server monitoring as well. Anyway, the possibilities are many, and vary according to your need and creativity.
CLR Function Source Code (C #):

using System; using System.Data.SqlTypes; using System.Net.NetworkInformation; public partial class UserDefinedFunctions { [Microsoft.SqlServer.Server.SqlFunction] public static SqlBoolean fncMaquina_Ligada(SqlString Ds_Hostname) { try { var ping = new Ping(); var reply = ping.Send(Ds_Hostname.Value, 5); //timeout em segundos return (reply != null) && (reply.Status == IPStatus.Success); } catch (Exception e) { return false; } } } |
Once compiled into the database, we can use the function like this:
And that's it folks!
Big hug and until the next post.
