Launching the Console Program remotely with DRAC

This is the only method for remotely launching the appliance’s Console Program until (unless) you enable SSH access for an appliance. For more information, see Setting up appliances.
When connecting remotely, you use the DRAC browser interface to select the appliance and open a console window in which you can launch the Console Program. The following procedure tells you how to access Foglight APM Appliances from a DRAC version 6 web interface. For general instructions on setting up and using the DRAC web interface, see the Dell Remote Access Controller documentation that comes with the appliance.
To launch an appliance’s Console Program remotely:
1
Launch the DRAC web interface. In Microsoft® Internet Explorer®, type the DRAC IP Address in the navigation bar.
2
First time only—Open the Internet Explorer Trusted Sites tool (in version 8.0, this is under Tools > Internet Options > Security), and add the Control Port IP Address for each of your appliances. Internet Explorer can now download and install signed ActiveX controls for your appliances.
3
Log in to the DRAC web interface with your DRAC user credentials. The default login name is root and the password is calvin.
4
To connect to an appliance, complete the following steps.
a
Click the Console/Media tab.
b
Select the appliance you want to set up, and click Launch Viewer.
c
If you are prompted to install the Java Runtime Environment, follow the online instructions and accept the default settings.
A console window opens for the appliance. You should see the login prompt.
d
If the appliance is in saver mode, press any key to continue.
5
To log in and continue the setup process, go to Setting up appliances.

Installing virtual appliances

The installation workflow depends on whether you are monitoring more than one host:
•
Monitoring multiple ESXi hosts — best approach for a large, scalable monitoring solution
•
Monitoring a single ESXi host — used for localized monitoring or proof of concept
 
* 
NOTE: For production environments, if you have not yet sized your web traffic environment with a Dell Sales representative, you should do so now to ensure you have the right number of Sniffers and Archivers to capture all monitored traffic.
This section begins with an overview of these scenarios and a summary of the installation workflows. The remaining sections provide detailed instructions for each step in the workflows:
•
Before you begin
•
Creating port groups on virtual switches
•
Deploying Foglight virtual templates
•
Deploying the Foglight virtual Sniffer template
•
Connecting virtual appliances on different servers
•
Powering on virtual appliances

Monitoring multiple ESXi hosts

These installation scenarios assume that you manage your virtual environment with vCenter® Server, distributed virtual switches, and port groups. You have a choice of two scenarios:
•
Monitoring multiple hosts through a centralized Sniffer (preferred)
•
Monitoring multiple hosts using local Sniffers (alternative)
The diagrams in each of these sections show the Foglight APM virtual machines in dark blue boxes. For more information about these components, see Software components.
For convenience, the following table summarizes support for key VMware® vCenter® features.

Monitoring multiple hosts through a centralized Sniffer

This is the preferred installation scenario because it is easy to deploy (fewer appliances), easy to scale, and easy to maintain. VMware® vMotion® is fully supported in this configuration, assuming that VMs move to hosts that are connected to the monitored network tap.
In this scenario, all the software components are on dedicated hosts: Management Server, Archiver, and Sniffer. You add a full-duplex network tap between the firewall and the server farm, and connect a virtual Sniffer to the tap. For high-traffic environments, you may prefer to connect physical Sniffers to handle the load more efficiently.
 
* 
NOTE: Because the network tap is external to the hosts, if applications interact with one another on the same host, this inter-application traffic is not captured. If you need to monitor this traffic, use the alternative configuration described in Monitoring multiple hosts using local Sniffers.
Figure 10. Monitoring multiple hosts through a centralized Sniffer
To connect a virtual Sniffer to a network tap, you create two Monitoring Network port groups (for example, Monitoring Network A and Monitoring Network B) and connect the NIC adapters to the monitoring ports on the full-duplex network tap. This enables the virtual Sniffer to capture the separate ingress and egress traffic flows in the same way a physical Sniffer captures it (see Connecting Sniffers to network taps).
Monitoring a physical network
You can monitor a physical network with virtual appliances. Install the network tap in the physical network as you normally would and set up the virtual appliances as shown. For more information, see Network taps.
