Understanding the Security Director Log Collector Deployment Modes

You can set up log collector(s) in both the VM and JA2500 appliance. You can configure log collector as an All-in-One node for small-scale deployments. For easy scaling, begin with a single Log Receiver node and Log Storage node, and incrementally add Log Storage nodes as your needs expand. You can add a maximum of one Log Receiver node and three Log Storage nodes.

For a VM environment, a single OVA image is used to deploy the All-in-One, Log Receiver, and Log Storage nodes. The image presents a configuration script after you log in. At deployment, you must select the memory and CPU configuration values, as is appropriate for the role of the VM.

For JA2500 deployments, a single ISO image is used to install the All-in-One, Log Receiver, and Log Storage nodes. The image presents a configuration script after you log in.

Requirements

To use the Junos Space Security Director Logging and Reporting module, your system must meet the following prerequisites:

Specifications for Deploying a Log Collector Virtual Machine on an ESX Server

You can use Table 231 and Table 232 to decide if you require a single Log Collector or multiple Log Collectors.

Table 231 and Table 232 provide the VM configuration recommended for the log collection to work effectively. It lists the required specifications for deploying a Log Collector VM on an ESX server for various sustained events-per-second (eps) rates. The eps rates shown in table were achieved in a testing environment. Your results might differ, depending on your configuration and network environment.

Log Collector Deployment Nodes

Table 233 shows different node types in which the Log Collector can be deployed.

Table 233: Log Collector Deployment Nodes

Node Type

Description

All-in-One Node (Combined deployment)

  • Both log receiver and log storage nodes run on the same VM or JA2500 appliance.
  • Supports eps of up to 3,000 with spinning disks and 4,000 with SSD drives.
  • Suitable for demos and small-scale deployments.

Log Receiver Node (Distributed deployment)

This node receives system logs from SRX devices. SRX devices must be configured with the log receiver node IP to send system logs. Upon configuration this node parses and forwards logs to log storage node. You must provide the IP address of the log storage node while configuring this node.

Log Storage Node (Distributed deployment)

This node analyzes, indexes, and stores the system logs. It receives the system logs from log receiver node.

Integrated

It is installed on Space node itself and it works as both the Log Receiver node and Log Storage node, similar to an All-in-one node.

Note: Using vSphere Client version 5.5 and previous versions, you cannot edit the settings of virtual machines of version 10 or later versions. For more details, see VMware Knowledge Base.

Note: You can only configure the IP address of all Log Collector nodes by using the configuration script. If an IP address is configured manually, the Log Collector node cannot be added to Security Director.

Storage Requirements

The total storage required for retaining X number of days at a given eps rate is:

eps * 0.155 * X = (in GB)

For example, the storage requirement for 7 days at 500 eps is 500 * 0.155 * 7 = 542 GB, with a +20% margin. The storage space is allocated and equally distributed to the log storage nodes.

Note: The logs get rolled over under the following scenarios:

  • Time-based rollover—Logs that are older than 45 days are automatically rolled over, even if the disk space is available.
  • Disk size-based rollover—Older logs get rolled over when the disk size reaches 400GB.

Deploying Log Collector as an All-in-One Node

An All-in-One node acts both as a Log Receiver and Log Storage node. For a VM environment, a single OVA image is used to deploy the All-in-One, Log Receiver, and Log Storage nodes. The image presents a configuration script after you log in and you must select All-in-One to configure the node. For JA2500 deployments, a single ISO image is used to install the All-in-One, Log Receiver, and Log Storage nodes. During setup, you can configure the node as an All-in-One node.

Figure 42 shows the deployment example using an All-in-One node.

Figure 42: Using an All-in-One Node

Using an All-in-One Node

Deploying Multiple Log Collectors

If you have a scenario where you require more log reception capacity or eps, you can add multiple logging nodes. Multiple logging nodes provide higher rates of logging and better query performance. You can add a maximum of one Log Receiver node and three Log Storage nodes.

For a VM environment, a single OVA image is used to deploy a Log Receiver node and a Log Storage node. The image presents a configuration script after you log in. During setup, you can configure the node as either a Log Receiver or Log Storage. At deployment, the user must select the memory and CPU configuration values, as is appropriate for the role of the VM or appliance.

For JA2500 deployments, a single ISO image is used to install the Log Receiver and Log Storage nodes. During setup, you can configure the node as either a Log Receiver or a Log Storage node.

The use of multiple logging nodes provide the following benefits:

Figure 43 shows the deployment example using multiple node for up to 10K eps.
