User Guide 19.11 documentation
SkyLIGHT PVX in stand-alone mode is a single unit which analyzes the traffic, stores the statistics, and presents the data through an interface.
SkyLIGHT PVX in a distributed mode will capture and analyze traffic in several physical locations through distinct appliances called “Captures”. They can be either physical or virtual appliances, which send their statistics to a central SkyLIGHT PVX unit called the “DataStore”. All of the data is aggregated into a single database and accessed through a single Graphical User Interface.
Whether you have one local Capture or several remote ones, what is taken into account for the sizing is the amount of data processed by the central datastore.
Therefore, the licensing model has only one and simple criterion: the central database capacity in terms of number of flow analysis. There are different versions in the SkyLIGHT PVX product range with the following capacity levels.
This product line is based on hardware appliances specifically tuned for high performance rates. The range of appliances available makes it possible to provide an adequate solution for all sizes of situations.
The hardware appliances only come in two versions:
This product line is designed for virtualization servers in VMware systems. The range of appliances available makes it possible to provide an adequate solution for all sizes of situations, depending on the resources (CPU, memory and disks) allocated to the virtual instances.
The SkyLIGHT PVX virtual appliances come in several versions in order to accommodate different customer needs.
The simplest way is to deploy the Evaluation version. You will find a dedicated widget called Integrated and Truncated Rows located in the Flows dashboard. It displays the number of different flow analyzes integrated in the database over the time. You will then be able to determine, at a glance, what version best fits your for your specific traffic.
Each SkyLIGHT PVX version supports a given number of flow analyzes. One flow analysis is either a set of exchanges between one client and one server for one application, or a layer 7 transaction.
If the data processed by the central datastore reaches the license limit, the system will still continue to work smoothly. An email alert will be sent to the administrator to make him/her aware that the limit has been reached.
A moving average over a period of one hour is used to determine if the licence limit is reached. This allows punctual, short data bursts. When the limit is exceeded, all flow analyzes will be ignored and will not be processed. In such a case, the result is that only a part of the total traffic will be analyzed. Flow analyzes start again once the hourly average goes back below the limit.
Apart from the Evaluation version, virtual and physical appliances are not provided with a license key. The license key will be sent to you by email.
Each PV entity, whether virtual, Capture and DataStore (see Distributed Architecture) needs a specific license. The licenses are specific to a given hardware serial number (the device id), so that each device must be sent its own license package.
Note
With this system, you can transform an APS
into an
APP
or an APS Free
into an APS express
for
example. However, when you transform any APP
probe into a
non-APP
, you must do a format_data_disk command
after installation to be able to save captured data. (See
Pulsar)
The same procedure must be performed for all the entities either for license or upgrades. Please follow the steps below:
user: ftp password: S3c7r!
put
) your license or upgrade file.Wait a few minutes and it’s done! The installation is complete when the license key is no longer available anymore when you refresh the destination folder lists.
Check your license or new version with the status
or capture
commands. For upgrades, please redo the same procedure on all the
entities.
Warning
To complete the upgrade, a reboot of all the probes is
mandatory (use the reboot
command in Pulsar or the
button in the GUI).
Note
Security
The FTP access is writable only (no read). It only allows to put a SkyLIGHT PVX signed and encrypted file. This file will be automatically moved, checked and executed by an internal process.
The upgrade packages can now also be uploaded on the Nodes Management page. Once uploaded (using the Upgrade Package button), you may push this installation package to each registered node directly via the web interface.
The status of the license can be validated in Pulsar with the “capture” command.
You can also check these informations through the web interface,
in the Nodes Management page of the Configuration section. The
page displays the PV version
and License
status of each
capture. See if your upgrade or license was correctly installed.
