Using ASP & SQL To Ping A Remote Server - Analyzing the ping attempts

(Page 5 of 6 )

The data returned from the sp_PingServer will contain the details of the four ping attempts in rows 4 to 7, as shown below:



The GetPingStats() function will break each line down to extract two things: the number of bytes sent per ping, and the time it took to reach its destination:

if Instr(1, rsObject.Fields(0).value, "timed out") = 0 then 'successful

'Get the number of bytes sent

intNumBytes = Mid(rsObject.Fields(0).value, Instr(1, rsObject.Fields(0).value, "bytes=") + 6, Instr(1, rsObject.Fields(0).value, "time<") - (Instr(1, rsObject.Fields(0).value, "bytes=") +6)-1)

intTime = Mid(rsObject.Fields(0).value, Instr(1, rsObject.Fields(0).value, "time<") + 5, Instr(1, rsObject.Fields(0).value, "TTL=") - (Instr(1, rsObject.Fields(0).value, "time<") +5)-3)

intTotalTime = intTotalTime + intTime

GetPingStats = GetPingStats & "Sent " & intNumBytes & " bytes, "

GetPingStats = GetPingStats & "which took " & intTime & " milliseconds: "

GetPingStats = GetPingStats & "<b>SUCCESS</b>"

intNumSuccess = intNumSuccess + 1

else 'The ping failed

GetPingStats = GetPingStats & " Couldn't Connect: "

GetPingStats = GetPingStats & "<b>FAILED</b>"

end if

Lastly, we create a summary of the ping attempts:

'Add a final stats line to the return value

GetPingStats = GetPingStats & "<br><b><u>Summary:</u></b><br>"

GetPingStats = GetPingStats & intNumSuccess & " out of 4 pings successful<br>"

GetPingStats = GetPingStats & "Took an average of " & intTotalTime / 4 & " milliseconds per ping<br><br>"

GetPingStats = GetPingStats & "<hr>"

When the function ends, the GetPingStats variable is automatically returned to the calling script, which simply outputs the value to the browser:

if getIP = "true" then

Response.Write DoPing(strHost)

end if

Calling the function with host I.P. 192.168.0.200, looks like this:
