Before you begin

After you select a monitoring solution, review the following topics to prepare for your installation:

•	Software environment

•	Foglight APM OVF templates

•	Required port groups

•	RAID configuration

•	Network information for virtual appliances

Software environment

Foglight APM templates require VMware® vSphere® running on the ESXi® hypervisor architecture. For supported VMware versions, see the Foglight APM Release Notes.

 

NOTE: VMware Workstation and VMware Player are not supported at this time.

The procedures in this section assume that you are managing your environment using vCenter® Server.

Foglight APM OVF templates

Foglight APM templates create a virtual device running under Suse Linux® Enterprise 11 (64-bit). The following templates are available, where x.x.x is the version number. For details about the virtual devices created by the templates, such as number of vCPUs and amount of RAM, see the Foglight APM Release Notes.

 

Table 7. Foglight APM templates

Template File Name	Deployed Software Components
Foglight-VirtualAPM-x.x.x	On separate virtual disks: • Management Server and APM cartridges • Archiver
Foglight-VirtualServer-x.x.x	Management Server and APM cartridges
Foglight-VirtualSniffer-x.x.x	Sniffer
Foglight-VirtualArchiver-x.x.x	Archiver

Each virtual appliance is built for a very specific purpose. There is no way to reconfigure a Sniffer virtual machine into an Archiver virtual machine. Delete any virtual machines you no longer need.

Required port groups

The installation diagrams showed port groups configured on the virtual switch that connects to the virtual network. The following table summarizes the required port groups and tells you whether you need to create the port group before you map to it. The purpose for each port group is elaborated below the table. For instructions on how to create these port groups, see Creating port groups on virtual switches.

 

NOTE: While the names provided are recommended for technical support purposes, you can use different names if you prefer.

 

Table 8. required port groups

Port Groups	Purpose	Required for	Create/Map	Map to
VM Network	Connects existing VMs and the appliances your intranet.	All appliances	Map	Network 1
Capture Network	Isolates the data being sent from Sniffers to Archiver.	Sniffers and Archivers located on different hosts	Create and map	Network 2
Monitoring Network	Connects Sniffers to monitor live web traffic occurring on your virtual network.	Sniffers only	Create and map	Network 3 and/or Network 4

VM network

A virtual switch includes a default VM Network port group, which is used to connect all virtual machines to the intranet. You use this same port group to connect the virtual appliances to the intranet. If your administrator changed the default port group name, substitute that name for VM Network in all relevant procedures. Once connected, the appliances can communicate with one another for administrative purposes. The Management Server also uses this connection to query the Archiver database and to transfer data from the Archiver database to the Foglight database. (The Foglight database collects data from multiple sources to display in the top-level APM dashboards.) Foglight users connect to the browser interface through this connection.

Capture network

Sniffers capture and decrypt web traffic and send the data in packets to Archivers for further analysis and storage. You need to isolate this transfer process from the rest of your traffic, both to maintain a high-level of component performance and to avoid monitoring the sent packets. When Sniffers and Archivers are on different hosts, you create and map a Capture Network port group for this purpose. For more information about how Sniffers and Archivers work, see Software components.

Monitoring network

Sniffers need access to the web traffic flowing to and from the web servers and application servers in your virtual network. Create and map a Monitoring Network port group on the virtual switch that connects to your live web traffic. The Monitoring Network port group must have its promiscuous mode set to Accept so that the Sniffer Appliance has access to the live web traffic passing through the virtual switch. You can have up to two Monitoring Network port groups per Sniffer, with the first mapped to Network 3 and the second to Network 4. When monitoring through a network tap, you use both Monitoring Network port groups to monitor the same traffic—one port for ingress traffic and the other for egress traffic.
