Get Server UP/Down status in c#

Devendra Kumar

First of all, I appolize, if it was out of topic, but it was important to get resolve. The question is little bit lengthy.

Output of the project should be:

Admin should view which server station is UP or DOWN

Overview of the project:

This project belongs to telecom sector, the thing is they have almost 200 transmission rooms which are inter connected through Optical Fibre Cable and can be accessible though IP address.

Lets take some example

Admin have 5 server station and that 5 servers have further child servers, they all are connected to each other and admin have all access to 5 servers and their child servers indivdually

Router A

|__ Router A1

| |__first

| |_second

|__Router B

|_ RB1

When I ping from their IP address, they are pinging.

Router A1 have 2 child server first and second, if they both are not connected to each other (means having break down), then how do I know that the server between first and second are DOWN.

What I thought to get the server UP and DOWN status is by pinging their IP address but the main problem I found that how can I know if first and second are not connected to each other.

Is their any alternate solution of ths or getting status by pinging the server station will be OK.

Please lookup the attached image and suggest the best possible solution.

Thanks Siva for showing interest in this. Let me try to explain my problem in a much simpler way. Please look at the image

Look at the center (The Main server). All nodes from A to O (routers/servers) are inter connected to main server, which can be accessible through its IP address. Node N has 2 sub nodes (service station) O and P where as K has sub nodes L and M.

L and M are connected (status is connected)

whereas the Orange line O and P, when disconnected from each other or having breakdown in their route, how the main server gets notification of that.

As I saw the current scenario, currently when their is any breakdown between O and P, either the admin has to login to the O server and checks whether the P server status is UP or Down OR the person sitting at the O server notify to the main server through phone call (means mannually).

Now, the owner of this telecom sector wants whenever their any breakdown in any of their servers, they want to get notified automatically on a screen.

NOTE: When connecting to each router, it requires a userid and password to login to their system.

Now, how can I detect that O is not connected to P and show the notification on the screen. which class in c# will help me to accomplish this task. Should any service needs to be installed on each server that notifies its sub nodes connectivity to the main server, there are currently (200 servers) which is not small.

What about the Pathping class, but still not know about knowing the connectivity between O and P.

Please give any idea/suggestion to achieve this. As I don't want to use any third party software to do this. I have to develop of my own, and in this technology there must be modification/enhancement in the application.

Kindly help me any one, any article or thing like that. If someone has code which is payable (I will).

Thanks
Devendra

Hi,

Sorry did not completely understand your problem. But if you are looking for a solution/Tool which can monitor your servers try to setup a Nagios instance. It's free and widely used infrastructure monitoring tool.Apart from just ping test, you can do a lot of checks.

Thanks Nilesh for your valuable reply but there isn't a networking issue.

Please review the snapshot again, client requirement is to view all these network up/down in an electric board (like as we have seen in railways/airlines for arrival and departure). For this I first need to show this in their PC and then interpret this result on the electric board.

As I said, all the stations are inter connected to each other which can be ping from the main center. Currently they are checking the server status by logging with their router IP and find which neighbours are not connected or by a telephone call. Now they want to view all this status all at the single screen.

Hope I had made myself clear, if not please inform and help me to get this solution.

I need to write a program for this or something else ia required.

Thanks
Devendra

Hey there !

This is something like networking problem, from my knowledge of networking, if this is the scenario of your problem I would suggest you to go for the AODV, or DSR algorithm for such problem, as they are the responsible entity that tells or analze which router is not connected or fails due to the reason. You can simulate this whole thing via NS simulator. May be programs are available over internet for AODV or DSR I don't know about that. I had done this thing in NS simulator so if you want it, I can help you with that.

In C# I haven't applied it, as might be the library of C# is not very compatible to resolve the networking issue.

Hope that might help you !
