Installation overview

Before installing appliances, you should familiarize yourself with the monitoring architecture and consider how the software components fit into your existing network.


	NOTE: Unless otherwise specified, appliances refers to both physical appliances (Dell PowerEdge™ series hardware) and virtual appliances (deployed on VMware® vSphere® Server).

Introducing the monitoring architecture

A typical monitoring implementation consists of several software components hosted on one or more appliances. For example, the simplest installation on a physical appliance consists of one All-In-One Appliance that contains Foglight Management Server, a Sniffer, and an Archiver as shown in the following diagram.

Software components

Foglight APM Appliances may host some or all of the following software components:

•

Foglight Management Server

•

•

In addition to the three primary software components, appliances with a Sniffer or Archiver include a Relayer component that handles communication between Sniffers and Archivers. Appliances with Archivers also include integrated Archiver databases. Finally, you may want to add Browser Instrumentation to your solution to capture client-side metrics.

The following sections describe each of the software components.

Foglight Management Server

For real user monitoring, the Foglight Management Server communicates with Sniffers and Archivers, queries the Archiver databases, stores Foglight-generated metrics, and performs some administrative tasks.

The Foglight browser interface contains dashboards for real user monitoring—organized under the APM menu—where you can:

•

configure traffic capture options (such as capture groups and sessionizing policies)

•

configure traffic analysis options (such as applications and analyzers)

•

search for and display details and metrics associated with hits, sequences, and sessions

•

review transactions and explore sequences

•

view geographical data on a map

•

replay end-user sessions

•

create and distribute reports

•

check the health of your appliances

You can use the Foglight Administration dashboards to perform various administrative tasks, such as assigning user roles and groups.
