RAID configuration

A multi-disk RAID configuration is strongly recommended (RAID 10 recommended).

Network information for virtual appliances

You need the following information ready when deploying virtual appliances to hosts.

 
* 
IMPORTANT: You must assign dedicated IP addresses to appliances. DHCP and dynamically-assigned IP addresses are not supported.
 
Table 9. Network information for virtual appliances
Network Information
Description
IP Address
•
Enables communication among the Server, Archivers, and Sniffers
•
Each appliance needs a unique and dedicated IP address that belongs to the same intranet subnet
•
Corresponds to the VM Network port group
Subnet Mask

Mask corresponding to the IP Address and subnet

Hostname

Optional—Domain name of the IP Address

Auxiliary IP Address
•
Enables data transfer from Sniffers to Archivers on different hosts
•
Each Sniffer appliance and Archiver appliance needs a unique Auxiliary IP Address that belongs to the same capture subnet
•
Corresponds to the Capture Network port group
Subnet Mask

Mask corresponding to the Auxiliary IP Address and capture subnet

Gateway IP Address
•
IP address of your network’s gateway
•
Same for every appliance on this network
Preferred DNS IP Address
•
Optional—IP address of the primary DNS server (supports DNS lookups)
•
Same for every appliance on this network
Alternate DNS IP Address
•
Optional—IP address of a secondary DNS server
•
Same for every appliance on this network

Creating port groups on virtual switches

We recommend that you create the port groups before deploying Foglight APM virtual appliance templates. This enables you to map the appliance’s network adapters to the port groups while deploying the template, rather than editing the installed VMs afterward. For an explanation of the port groups, see Required port groups.

Follow the procedure for the type of virtual switches used with the selected installation scenario:

•
Monitoring Multiple Hosts — Configuring port groups on a distributed switch
•
Monitoring a Single Host — Configuring port groups on a standard switch

Configuring port groups on a distributed switch

The following procedures assume that your environment already has a distributed switch with a port group that connects to the intranet. This existing port group corresponds to the VM Network described in Required port groups. If you do not have a distributed switch, see the VMware® documentation for instructions on how to create one and configure a VM Network port group.

The default name of the distributed switch is dvSwitch. Your switch name may be different. If so, substitute that name in this procedure.

 
* 
NOTE: Port mirroring is not recommended because configuring RSPAN VLAN on the physical switch that connects ESXi® hosts generates a substantial amount of additional (and essentially duplicated) network traffic. For information about port mirroring, see the VMware® documentation.

For more information, see the following topics:

•
Creating a Monitoring Network port group required by Sniffers
•
Creating the Capture Network port group required by Sniffers and Archivers
•
