2.3 Recommended Collector Manager Limits

The limits mentioned in this section are recommendations based on the performance testing done at Novell or at customer sites. They are not hard-limits. The recommendations are approximations. In highly dynamic systems, it is a good practice to build in buffers and allow room for growth.

Unless otherwise specified, Collector Manager limits assume 4 CPU cores at 2.2 GHz each, 4 GB of RAM, running on SLES 11.

Maximum number of Collector Managers

20

This limit assumes each Collector Manager is running at low EPS (e.g, less than 100 EPS). The limit decreases as the events per second increase.

Maximum number of Connectors (fully utilized) on a single Collector Manager

1 per CPU core, with at least 1 CPU core reserved for the operating system and other processing

A fully utilized Connector is one that is running at the highest EPS possible for that type of Connector.

Maximum number of Collectors (fully utilized) on a single Collector Manager

1 per CPU core, with at least 1 CPU core reserved for the operating system and other processing

A fully utilized Collector is one that is running at the highest EPS possible for that type of Collector.

Maximum number of event sources on a single Collector Manager

2000

The limit of the Sentinel server is also 2000, so if 2000 event sources are on a single Collector Manager, then the limit of event sources for the overall Sentinel system has been reached with that single Collector Manager.
