Ping With Timestamp In powershell
Eliora Shopbell
There isn't one unfortunately. As others have mentioned it can be done with a powershell script. Ping monitor is my go to for this stuff as I can ping multiple IPs for as long as I want and it logs events. Free for up to 5 IPs at a time which for me fits almost every use case. Any more than that and I'm looking at PRTG.
Quick Note: Your Transcript stops either when you close your powershell window, or you run 'Stop-Transcript' - Keep this in mind and don't accidentally make yourself an 80000 line text file with weeks worth of powershell work.
the timeout switch is not the same as what you are looking for as a 'wait' switch. The timeout switch with Windows ping command simply tells the command window how long to wait before RECEIVING the reply, not how long to wait before sending the NEXT reply.
Test-Connection uses the TargetName parameter to specify Server01. The Count parameterspecifies three pings are sent to the Server01 computer with a Delay of 2-second intervals.
The Test-Connection cmdlet pings the Server01 computer, with the Quiet parameter provided.The resulting value is $True if any of the four pings succeed. If none of the pings succeed,the value is $False.
Causes the cmdlet to send ping requests continuously. When the value of TargetName is an arrayof targets, the cmdlet repeats the ping requests for the first target only. It ignores theremaining targets. This parameter can't be used with the Count parameter.
Ping is the most basic and the most oldest built-in tool, that every system/network administrator cannot live without when troubleshooting network connection at TCP/IP Layer-3. I sometimes had to make long time ping test for network latency issues.
Above script will keep on looping until the system comes up, and returns the value $tnc. it will have the time when the ping succeeded. So you can add a check if it failed and save it in a variable, the return it along with $tnc using calculated property.
Pardon me if I missed you already doing this, but I suggest running more scripts at the same time you run a PowerShell loop recording results and timestamp while pinging 8.8.8.8 and 8.8.4.4. Run one to ping the LAN IP of the 330, one to ping the WAN IP, one to ping the ISP's gateway, and one to ping the ISP's DNS servers (which should be closer to your 330 than Google's DNS).
update: On a computer installed on the secure (trusted) network of the xtm330 I'm running a powershell loop logging (ping of an external site results, timestamp, and nmap -sp scan of the local network) results. lately the ping results fail at 10:51am and are back up by 10:53am. I notice when the nmap scan and pings run, nmap usually logs 15 devices. when the ping fails, the nmap scan displays 2 devices (itself, and one other computer) ...until the network comes back. I now believe this outage, is on my network, not the ISP. I'm running wire shark, logging, where I'm seeing packets during the outage time originating only from the machine running the network ping loops. I'm not sure if this is an xtm330 problem or what is happening at this point.... continuing to dig.
The only method that should be used from a user is the ping method. This method is called without any additional parameters, as everything should be set and saved in class variables.
As I like the linux style syntax ping, we will create a $startMessage as it would appear at every start of a ping in Ubuntu for example.
After writing out that message, we have to create an instance of System.Net.NetworkInformation.Ping and System.Net.NetworkInformation.PingOptions. We need the PingOptions instance to be able to define ttl and dontFragment options.
In line 47 the $buffer variable of type byte array will be initialized with the length of $this._bytes.
So every instance of the above line is a ping failure and all successful pings will NOT be recorded to the file. This allows me to open a small text file and at a glance see the specific times a particular IP address was inaccessible. The hope is to be able to line up ping failures with backup failures. But this could be used in troubleshooting many random timeout errors in applications, etc.
Sometimes it is handy to run ping on the background to monitor network connectivity. Combine Microsoft PowerShell and the PsPing utility from Microsoft and you get a nice logging solution with shows on each line a timestamp and the results from the ping.
The script is already commented out to explain things step by step but essentially, for each site in sites.txt, powershell will Test-Connection once for each role in roles.txt and output the result complete with Up/Down status, a timestamp and the hostname.
I'm try to monitoring my VPNs status with splunk, unfortunately my firewall does not log vpn up or down.
So I made a powershell script that makes every 4 minutes a set of pings to an IP on the destination site of each VPN.
Each ping gets exported to a csv file, automatically renamed with timestamp to a new source file name from each vpn.
This command attempts to ping each IP address in the loop in sequence. It filters out IPs which do not respond with the Select-String cmdlet thereby only displaying lines that include the text "TTL".
Second, I collected evidence about the network disconnection between PN1 and PN2 around 5:18 PM on 10/13/2021. I used a tool, named hrping ( ), to help with my diagnosis. This is a very useful free tool. Please refer to this tool's guide about using the tool to log the "time out" to the text files.
Pester, along with native PowerShell applets, can be used to create a variety of scripts to test network functions and security with. For example, Pester could be used to create a test to ping every IP address on a specific subnet to see if any IP addresses are responding that shouldn't be.
Though pinging equipment on a network with PowerShell is as straightforward as pinging a device with Command Prompt, it's not hard. I'd wager to say that the only thing more difficult about using PowerShell is the number of characters you need to type to send a ping.
The first is the '-TargetName' command. Target name takes its parameters in the form of a string value. So, when you use this command, the IP address you are trying to ping will be read as a string in the 'Test-Connection' applet and not four different octet values. You can also pass an array of IP addresses with '-TargetName' if you want to send a ping to more than one device.
In this video, Trevor Sullivan covers how to write a simple ping test with the open-source Pester test framework. You will learn how to use the Pester PowerShell module, how to write a practical test within PowerShell, and how to complete a basic ping using the test connection command in PowerShell.
