Port Mirroring scenario understanding

Hi,

Hope you are doing fine.

We require port mirroring for traffic duplication, we have one vm in DMZ on different (ESXI) and the probe vm is on a different (ESXI), how port mirroring should be done in that scenario? Our vms are on different ESXIs.

waiting for  your kind response.

Hello,

in order to Collect RUM Data from a Virtual environment, you must Place the RUM Sniffer and monitored server on the Same ESXi, and same Virtual Switch. 

Also if VMotion is Enabled, there is an option in vCenter to create a link between two VMs and to
configure them to move together between ESXi.

Hi Saad,

Thank you so much for your response.

Do you have an idea of below mentioned configuration?

Hello Mike, 

Configure the RUM Probe to run on the same ESX as the monitored application. There is an option in
VMware to keep two VMs together on the same ESX to improve efficiency. This option can also be used
for keeping the probe and monitored application on the same ESX.

To keep two VMs together:
a. Right-click the DRS cluster that contains the VMs you want to keep together.
b. Select Edit Settings.
c. Under VMware DRS click Rules.
d. To create a rule click Add.
e. In the dialog box that opens, enter a name for the rule.
f. Select the rule type Separate virtual machines/Keep virtual machines together.

g. Click Add to select the virtual machines to which the rule applies. Accept the selection by clicking
OK twice.
h. Click OK to save and exit the settings.

For further details, see http://www.vmware.com/pdf/vmware_drs_wp.pdf.  check Page 19

Hello Mike,

if you are going to Monitor 2 VMs  in 2 different ESXi, you should have 2 Probes, one on each ESXi,

 

otherwise, you can use RUM Server Collector Agent.  But be aware of the Agent impact of the network.

For example, you can use the RUM Server Collector if the network traffic is not high (150 Mbps for windows and 250 Mbps for Linux) and if you are aware of the implications.
