Creating a collector

A collector receives raw events from event sources, performs normalization, and sends processed events to their destinations. The maximum size of an event that can be processed by the KUMA collector is 4 MB.

If you are using the SMB license, and both the hourly average EPS and the daily average EPS allowed by the license is exceeded for a collector, the collector stops receiving events and is displayed with a red status and a notification about the EPS limit being exceeded. The user with the General Administrator role gets a notification about the EPS limit being exceeded and the collector being stopped. Every hour, the hourly average EPS value is recalculated and compared with the EPS limit in the license. If the hourly average is under the limit, the restrictions on the collector are lifted, and the collector resumes receiving and processing events.

Installing a collector involves two steps:

• Create the collector in the KUMA web interface using the Installation Wizard. In this step, you specify the general collector settings to be applied when installing the collector on the server.
• Install the collector on the network infrastructure server on which you want to receive events.

Actions in the KUMA web interface

The creation of a collector in the KUMA web interface is carried out by using the Installation Wizard. This Wizard combines the required resources into a set of resources for a collector. Upon completion of the Wizard, the service itself is automatically created based on this set of resources.

To create a collector in the KUMA web interface,

Start the Collector Installation Wizard:

• In the KUMA web interface, in the Resources section, click Add event source button.
• In the KUMA web interface in the Resources → Collectors section click Add collector button.

As a result of completing the steps of the Wizard, a collector service is created in the KUMA web interface.

A resource set for a collector includes the following resources:

• Connector
• Normalizer (at least one)
• Filters (if required)
• Aggregation rules (if required)
• Enrichment rules (if required)
• Destinations (normally two are defined for sending events to the correlator and storage)

These resources can be prepared in advance, or you can create them while the Installation Wizard is running.

Actions on the KUMA Collector Server

When installing the collector on the server that you intend to use for receiving events, run the command displayed at the last step of the Installation Wizard. When installing, you must specify the identifier automatically assigned to the service in the KUMA web interface, as well as the port used for communication.

Testing the installation

After creating a collector, you are advised to make sure that it is working correctly.
