Linux – How to view the TCP Send and Receive Queue sizes on Windows

linuxnetworkingtcpipwindows

Linux netstat shows send and receive queue sizes.

How do I get this info under Windows, specifically Server 2003?

This question is old but I wanted to add some information. It's a fairly high search result on Google.

As far as I can tell there is not a way to do this, but if anyone can do more digging and figure out a valid alternative that would be much appreciated!

As @Fencepost pointed out in his answer, you can try to query NDIS OIDs. The most relevant NDIS OID I found is OID_GEN_TRANSMIT_QUEUE_LENGTH

Most of the NDIS OIDs are mapped to WMI classes, you can list them in powershell with

Get-WmiObject -Namespace root\wmi -List  | Where-Object {$_.name -Match "MSNdis" } | Sort-Object

but there doesn't seem to be one for Transmit Queue Length.

@Chris J mentioned Network Interface\Output Queue Length. You can get this value on the command line with typeperf.

typeperf "\Network Interface(*)\Output Queue Length" -sc 1

But the value is always 0: http://support.microsoft.com/kb/822226

Windows only keeps track of this information in the NIC driver software, and it's only packets queued per NIC, and doesn't distinguish between what's queued per socket.

If you do want to do network debugging on the command line, any counters you find in perfmon can be queried using typeperf or logman.

For Git Bash

If you are running msysgit (I am assuming you are) and are looking to run Git Bash (I recommend it over TortoiseGit, but I lean to the CLI more than GUI now), you need to figure out what your home directory is for Git Bash by starting it then type pwd (On Windows 7, it will be something like C:\Users\phsr I think). While you're in Git Bash, you should mkdir .ssh.

After you have the home directory, and a .ssh folder under that, you want to open PuTTYgen and open the key (.ppk file) you have previously created. Once your key is open, you want to select Conversions -> Export OpenSSH key and save it to HOME\.ssh\id_rsa. After you have the key at that location, Git Bash will recognize the key and use it.

Note: Comments indicate that this doesn't work in all cases. You may need to copy the OpenSSH key to Program Files\Git\.ssh\id_rsa (or Program Files (x86)\Git\.ssh\id_rsa).

For TortoiseGit

When using TortoiseGit, you need to set the SSH key via pacey's directions. You need to do that for every repository you are using TortoiseGit with.

Linux – How to monitor current output/receive queue length in Linux

It is available in IF-MIB. I'm assuming you already have an snmpd running that supports IF-MIB, if not you'll need to install something like net-snmp. After that walk the box and look for:

http://www.oidview.com/mibs/0/IF-MIB.html

IF-MIB::ifOutErrors.4 = Counter32: 0
IF-MIB::ifOutQLen.1 = Gauge32: 0

From the MIB definition:

The length of the output packet queue (in packets).
