    ping an address, log errors to text file with timestamp
    « on: June 10, 2011, 11:00:11 PM »
    Hi,
    I am aware that this requirement has been answered in a number of different ways, but none of them seemed that elegant to me (by elegant read short & simple).
    I would like to leave a ping running (ping -t) and have any response that is a not a reply be written to a text file along with the time and date.

    It's the time and date thing that's got me stumped.

    First bit working fine for me:

    ping -t 195.40.1.36 | find /v "Reply from 195.40.1.36" >> pinglog.txt

    Could anyone please let me know how to add the time and date to what gets written out.
    Many thanks.

      Not too sure where you're going with that one. Doesn't seem to work for me.
      I get the failed pings written out to a log file but they aren't timestamped.

      I could use the following batch file. Works fine, but it doesn't record the reason for failure, just that it did fail and the time it happened (and there's probably a cleverer way to pause for 1 second.....)

      The reason for failure would be really handy.

      @echo off
      :loop
      ping -n 1 %1 >nul || echo %date% %time% no reply from %1 >> pinglog.txt
      choice /N /T 1 /D Y >nul
      goto loop

        I don't want him to bounce me into posting an untested and incompletely considered reply. Please bear with us a little longer!

        No worries and much appreciated.

        The script below addresses the simplest case I can think of, namely a host which exists and which either is or is not servicing ping requests. If the ping command is "successful" then it looks like this...

        Code: [Select]
        C:\>ping -n 1 192.168.56.129

        Pinging 192.168.56.129 with 32 bytes of data:
        Reply from 192.168.56.129: bytes=32 time<1ms TTL=128

        Ping statistics for 192.168.56.129:
            Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
        Approximate round trip times in milli-seconds:
            Minimum = 0ms, Maximum = 0ms, Average = 0ms

        If not, it looks like this

        Code: [Select]
        C:\>ping -n 1 192.168.56.129

        Pinging 192.168.56.129 with 32 bytes of data:
        Request timed out.

        Ping statistics for 192.168.56.129:
            Packets: Sent = 1, Received = 0, Lost = 1 (100% loss),

        I only send 1 request for the sake of avoiding network congestion

        The IP I am using is a local XP machine whose firewall I turn on and off

        As you will see the meat is in the 2nd non-blank line, and we can examine this and decide whether to write it to a log file, preceded by the date and time. To make a delay I use the free sleep utility which is part of the Windows Server 2003 Resource Kit Tools which you can download here:

        http://www.microsoft.com/downloads/en/confirmation.aspx?familyid=9d467a69-57ff-4ae7-96ee-b18c4790cffd

        There are plenty of others around but not all have the -m (milliseconds) feature.

        Code: [Select]
        @echo off
        setlocal enabledelayedexpansion
        set hostIP=192.168.56.129
        :loop
        set pingline=1
        for /f "delims=" %%A in ('ping -n 1 -w 250 -l 255 %hostIP%') do (
        if !pingline! equ 2 (
        set logline=!date! !time! "%%A"
        echo !logline! | find "TTL=">nul || echo !logline! >> pinglog.txt
        )
        set /a pingline+=1
        )
        sleep -m 5000
        goto loop


        The IP you used as an example resolves to lr-rns.timik.uk.easynet.net on my machine; I wonder if you are wanting to log times and/or periods of bad Internet connection or whether it was just an example?

          Thank you so much. Works perfectly.
          I'll need to substitute my delay
          choice /N /T 1 /D Y >nul
          for your rather neater sleep utility as I don't have the option of installing anything.

          Are you doing a FIND on "TTL" because it is only a healthy reply that would ever have those characters in it?

          The IP I used in the example is just an ISP's nameserver that hasn't changed in 15 years and for some reason I've always defaulted to it.

          I'll be using the script to troubleshoot an intermittent network dropout on some servers at work. I plan on pinging a known good IP (our main data centre router) from multiple servers. By correlating the logs I should be able to determine if the dropouts are due to OS, hypervisor, switch or data centre (at least that's my theory!).

          Thanks again. Love your nic by the way, started reading 'The Salmon of Doubt' by Douglas Adams just yesterday.

          Yup. Note the || operator (execute 2nd command if 1st command returns nonzero errorlevel - the opposite of &&)

          Also note that the message "Request timed out" is quoted because I am echoing %%A, the 2nd nonblank line of the ping output, via a pipe to find, and a healthy response on my system shows the response time field as "time<1mS" and the < symbol in an unquoted literal string or expanded variable breaks script processing because it has a special meaning (redirection).

          If you don't want the quotes to appear in the log see below

          Code: [Select]
          @echo off
          setlocal enabledelayedexpansion
          set hostIP=192.168.56.129
          :loop
          set pingline=1
          for /f "delims=" %%A in ('ping -n 1 -w 250 -l 255 %hostIP%') do (
          if !pingline! equ 2 (
          set logline=!date! !time! "%%A"
          echo !logline! | find "TTL=">nul || (
          set logline=!logline:"=!
          echo !logline! >> pinglog.txt
          )
          )
          set /a pingline+=1
          )
          sleep -m 5000
          goto loop
             

          Before...

          Code: [Select]
          11/06/2011 14:44:42.28 "Request timed out." 
          11/06/2011 14:44:47.78 "Request timed out."

          11/06/2011 14:45:20.78 "Request timed out." 

          After...

          Code: [Select]
          11/06/2011 14:47:11.28 Request timed out. 
          11/06/2011 14:47:16.78 Request timed out.

          11/06/2011 14:47:38.78 Request timed out. 
          11/06/2011 14:47:44.28 Request timed out. 
          11/06/2011 14:47:49.78 Request timed out.

          Alternative method using VBScript - save with .vbs extension and call with cscript.exe supplying IP and log file name. In some ways more "elegant", maybe?

          e.g. cscript mypingscript.vbs 192.168.56.129 logfile.txt

          Code: [Select]
          hostIp      = wscript.arguments(0)
          logfilename = wscript.arguments(1)
          Set fso     = CreateObject("Scripting.FileSystemObject")
          Set Shell   = CreateObject("Wscript.Shell")
          Set logfile = fso.OpenTextFile(logfilename, 8, True)
          shellstring = "%comspec% /c ping -t " & hostIP
          Set oExec   = Shell.Exec(shellstring)
          wscript.echo "Ping Error log With Timestamp - Ctrl + C to halt"
          Do While oExec.StdOut.AtEndOfStream <> True
          pingline = Date & " " & Time & " " & oExec.StdOut.ReadLine
          If Not InStr(pingline, "TTL=") Then
          logfile.WriteLine(pingline)
          End If
          Loop

            The nice thing about that one is that when you exit the script the ping stats get written to the log file.  Unfortunately for me every line is being written to the log file (the "TTL=" isn't working). The original dos script you wrote is perfect though. Thanks again.

              Fantastic. Will implement tonight and let you know how it goes in a couple of days.
              The fact that with the vbscript you get the ping stats for the whole session written to the tail of the log file is very cool.

                Wanted to take the time to register on this forum and congratulate Salmon Trout for providing a 1st class solution.  I have looked far and wide for something elegant, simple, robust that works and was only able to find it in Salmon's solution. 

                I added TRACERT into the single logical operator line to get additional useful information for troubleshooting:

                echo !logline! | find "TTL=">nul || echo !logline! >> NetworkPingErrors.txt && echo Running TraceRT, please wait.... && tracert %hostIP% >> NetworkPingErrors.txt && echo ----------- >> NetworkPingErrors.txt
                 
                Thank you very much sir!  Hats off to you.

                Nice to see after nearly a year that somebody found it useful.

                mmedia man, you are using the double ampersand (&&) as a command separator, I hope you remember it is actually an AND operator - that is:

                command1 && command2     command2 is only executed if command1 returns a zero errorlevel

                The opposite is the double pipe OR operator.

                command1 || command2     command2 is only executed if command1 returns a non-zero errorlevel

                The ordinary command separator is a single ampersand

                command1 & command2 command2 is always executed



                example:

                Code: [Select]
                C:\>dir /b notexist.fil && echo command2
                File Not Found

                C:\>dir /b notexist.fil & echo command2
                File Not Found
                command2

                In most cases it may not matter which one you use, but there may come a situation where a string of commands on one line will halt part way through if you use && when you don't actually intend to test the preceding errorlevel.

                  just registered this forum to thank you for such an excellent script.
                  however, it still does not print
                  "request timed out"
                  in my case..
                  it simply writes
                  "ping request could not find host www.google.com. Please check the name and try again."

                  for my case i need to count how many RTO's occured to measure the bandwidth quality.
                  so is there anyway to make it print the rto's as well?
                  thanks

                  Do you want every line or just "request timed out" or what exactly?

                    Just "request timed out"
                    It would be great if there's a total amount of RTO's at the end, but if not it's ok

                    Try this modified VBS code from above.

                    Save it as pinglog.vbs

                    Code: [Select]
                    hostIp      = wscript.arguments(0)
                    logfilename = wscript.arguments(1)
                    Set fso     = CreateObject("Scripting.FileSystemObject")
                    Set Shell   = CreateObject("Wscript.Shell")
                    ' OpenTextFile Method requires a Const value
                    ' (Over)Write = 2  Append = 8   
                    Set logfile = fso.OpenTextFile(logfilename, 8, True)
                    shellstring = "%comspec% /c ping -t " & hostIP
                    Set oExec   = Shell.Exec(shellstring)
                    wscript.echo "Ping Error log With Timestamp - Ctrl + C to halt"
                    Do While oExec.StdOut.AtEndOfStream <> True
                          pingline = Date & " " & Time & " " & oExec.StdOut.ReadLine
                          If InStr(pingline, "timed out") > 0 Then
                             logfile.WriteLine(pingline)
                          End If
                    Loop


                    And save this as pinglog.bat

                    Code: [Select]
                    @echo off
                    del pinglog.txt 2>nul
                    cscript /nologo pinglog.vbs "%~1" pinglog.txt
                    echo found this many timed out responses
                    find /c /i "timed out" <pinglog.txt
                    pause


                    and execute it like this:  pinglog.bat www.telstra.com


                    Remove this line from the bat file if you want a permanent log, but the count will be of the entire file.

                    del pinglog.txt 2>nul

                      Hello Salmon Trout, its a nice script!!

                      Could you increase a code to add every one (or N) hour(s) in a log-file, a successful ping with address.
                      example:

                      05/01/2013 10:28:07 Reply from 74.125.234.39: bytes=32 time=41ms TTL=55
                      05/01/2013 11:28:07 Reply from 74.125.234.39: bytes=32 time=39ms TTL=55
                      etc...

                      I have a doubt:

                      I have used www.google.com as a reference...

                        lping.vbs www.google.com lping.log

                      If the Google IP change, your script will think that it is off-line?
                      I'm not sure if in your code, gets the Google IP at the start and always keeps the same!
                      It always checks the Google IP inside the loop or not?
                      Sorry-me about this, but Im not very familiar with VBScript!

                      and thank you for the script!!  :)

                      This will use ping for each invocation and it will do a fresh DNS lookup for each ping,
                      and should only write the failed lines,
                      and will write a line to the log like ' DATE TIME - pinging "www.google.com" ' every so often.

                      The frequency of the above log update (when no failure events are present) is determined by the 3600 in the for /L line.
                      On my machine with Windows 8 then the 3600 equates to around 4 minutes.

                      It just occurs to me that although this will flush the local DNS cache, your broadband modem also maintains a DNS cache and it will provide the stale DNS info for the URL.

                      This doesn't work out of the box for XP (you will require skip=3 and the log will double space), and I didn't check vista or Win 7.


                      Code: [Select]
                      @echo off
                      if "%~1"=="" (
                      echo Enter an IP address or domain name
                      echo Example Syntax: %0 www.google.com
                      pause
                      goto :EOF
                      )
                      setlocal enabledelayedexpansion
                      :loop
                      >> pinglog.txt echo !date! !time! - pinging "%~1"
                      for /L %%a in (1,1,3600) do (
                      ipconfig /flushdns >nul
                      for /F "skip=2 delims=" %%b in ('ping -n 1 "%~1"') do (
                      if not defined var (
                      echo "%%b"|find "TTL=">nul ||(>> pinglog.txt echo !date! !time! - %%b)

                        Thank you for posts. Here's a variation of just the ping test.

                        pingtest.vbs
                        Code: [Select]
                        ' Ping once every 5 minutes
                        ' Timeout after 1 second
                        ' Write TTL ping line with timestamp
                        ' Write request timeout with timestamp

                        hostIp      = wscript.arguments(0)
                        logfilename = wscript.arguments(1)

                        Set fso     = CreateObject("Scripting.FileSystemObject")
                        Set Shell   = CreateObject("Wscript.Shell")

                        ' OpenTextFile Method requires a Const value
                        ' (Over)Write = 2  Append = 8   

                        Set logfile = fso.OpenTextFile(logfilename, 8, True)
                        shellstring = "%comspec% /c ping -n 1 -w 1000 " & hostIP

                        wscript.echo "pingtest to logfile - Ctrl + C to halt"

                        Do While True
                            Set oExec   = Shell.Exec(shellstring)
                            Do
                        pingline = Date & " " & Time & " " & oExec.StdOut.ReadLine
                        If InStr(pingline, "TTL=") <> 0 Then
                        logfile.WriteLine(pingline)
                        End If
                        If InStr(pingline, "Request timed out.") <> 0 Then
                        logfile.WriteLine(pingline)
                        End If
                        Loop While Not oExec.Stdout.atEndOfStream
                        ' WScript.Sleep(1000)
                        WScript.Sleep(1000 * 60 * 5)
                        Loop


                        Example run:

                          Hi guys,

                          I'm a total noob when it comes to windows and scripts,
                          Trying to sort a connection issue and would love to simply log changes in the status (either "reply from" or "request timed out") with a timestamp.

                          Can anyone help? (also with what to run / save it as) as I said, widows script noob

                          Thanks in advance.

                          It would help for you to show the sort of thing you need to get in the log file.

                            Just timestamp with ping reply/timeout but only log the first instance of each as it changes. That way I can see and show the connection drops and for how long without a huge log.
                            If it's not easy to do, then I can do it manually. Some advice on the steps to take to save & run whichever script above will simply log with timestamps would be great though.

                            Nope. Nada on scripts in windows ever.

                            I think Foxidrive was asking for a concrete example of the output you want to see in your log file.

                              Request timed out.
                              Etc, with timestamps..

                              ie the changes in status, I don't need every reply, just the first as connection drops and is regained to easily show when each connection issue starts and stops.

                              I think you would be better off with a dedicated program to do this.
                              When I was a Network admin this is just one of the simple tools I would use.
