show tcp statistics

Hi,

There is a command "show tcp statistics" to get tcp statistics.

whether this tcp statistics are of VSM or it includes tcp statistics of VSM+VMs on ESX.

Thanks,

These are the TCP statistics of the VSM only and does not include the stats for the VEM or VMs on the ESX

Hi,

How can I get TCP statistics for VMs on VEM?

Should I use Netflow or ERSPAN? or

Is there any other way to get the same?

Thanks,

Following configuration can be used to get tcp statistics for VMs:

flow record protocol-stats

match ip protocol

collect counter bytes

collect counter packets

flow exporter exp
  destination <collector-ip>

flow monitor protocol-stats
  record protocol-stats
  exporter exp

By using above config you should be able to collect protocol-wise stats for all the interfaces on a VM. You can put following config in a port profile or directly on the interface which you want to monitor:

ip flow monitor protocol-stats input

ip flow monitor protocol-stats output

This would monitor traffic in both egress and ingress with respect to VM.

The "show tcp statistics" command typically provides TCP stats for the VSM only, not including VMs on an ESX server. For VM statistics, you'll need to run commands directly within each VM or use a comprehensive monitoring tool.

These statistics help in diagnosing issues like congestion, connection drops, or suboptimal configurations, enabling targeted interventions to enhance network efficiency.

The command "show tcp statistics" provides TCP statistics that are generally related to the entire ESX host, which includes both the VSM (Virtual Supervisor Module) and the VMs running on the ESX host. This means the statistics cover TCP connections and performance metrics for all traffic passing through the ESX host, encompassing both the VSM and any virtual machines.

If you need statistics specific to only the VSM or individual VMs, additional commands or filters might be required, depending on the management tools and interfaces you are using. Receiptify spotify

I hope this helps! Let me know if you need further clarification.

There's a command called "show tcp statistics" for retrieving TCP statistics. Could you clarify if these statistics pertain only to VSM or if they include TCP statistics for both VSM and VMs on ESX?

Thanks

The command "show tcp statistics" displays TCP metrics for the entire ESX host, covering both the Virtual Supervisor Module (VSM) and any virtual machines (VMs) on that host. This output includes TCP connection details and performance metrics for all traffic flowing through the ESX host, spanning both the VSM and the VMs.

For statistics limited to just the VSM or individual VMs, you may need additional commands or filters, depending on the management tools and interfaces available. cost of golden corral buffet
