Monitoring physical networks

Physical appliances provide the best data capture rates and storage capacity in large organizations with high web traffic environments. The following image shows a typical installation of four appliances: Foglight Server Appliance, Sniffer Appliance, and two Archiver Appliances.

 

NOTE: If you have an existing Foglight installation, you can add Sniffer Appliances and Archiver Appliances to your network. You need to install the Foglight APM cartridge and ensure that the public network switch where your appliances are plugged in also has a connection to the server hosting your Foglight Management Server.

Figure 2. Monitoring physical networks

Each Control Port and DRAC Port needs to be assigned its own public IP address. For more information, see Installing physical appliances.

Monitoring virtual networks

Virtual appliances offer good data capture rates and storage capacity ideal for mid-traffic web environments. In a typical installation scenario, you identify the virtual networks supporting the web sites or applications you want to monitor and deploy a Sniffer to monitor the VMware® ESXi® hosts. You also deploy a Management Server and one or more Archivers on dedicated hosts.

Figure 3. Monitoring virtual networks

For more information about this installation scenario and other variations, see Installing virtual appliances.

Mixing physical and virtual appliances

You may discover uses for both physical and virtual appliances in your environment. For example, you may want to use physical appliances for a large-scale, corporate network and virtual appliances for a single, lower traffic website hosted in another geographic location.

 

IMPORTANT: You can have both physical and virtual Sniffers in the same capture group, but physical and virtual Archivers must be in separate capture groups.

Adding Foglight APM to an existing Foglight installation

Many Foglight customers choose to add application performance monitoring and real end-user monitoring to their existing Foglight installation. In this case, you do not need an appliance-hosted Management Server. Instead you install the Foglight APM cartridge on the existing server-hosted Management Server (64-bit installations only). You can add as many Sniffer and Archiver appliances (virtual or physical) as you need to your network and register the appliances in the server-hosted Management Server.

You can add additional Management Servers to support a federated environment or a high availability cluster, with the following restrictions:

•	Federated Environment — Server-hosted Management Servers can participate in a federated environment as either the Federated Master or as a Federated Child. Appliance-hosted Management Servers can be enabled only as Federated Children.

•	High Availability (HA) Cluster — Server-hosted Management Servers can participate in an HA cluster. Appliance-hosted Management Servers are can not be used because they do not permit access an external database, which is a requirement for all HA clusters.

For instructions on how to install and set up Foglight APM on server-hosted Management Servers, see Setting up server-hosted Management Servers.
