Monitoring with a CA Virtual Systems Monitor › How a CA Virtual Systems Monitor Works as a Monitoring Device › Port Usage and Firewalls

Port Usage and Firewalls

When you set up the CA Virtual Systems Monitor and prepare to add it as a monitoring device, you need to consider any firewalls that could prevent communications between the CA Virtual Systems Monitor, which resides on a virtual machine, and the management console, which resides on a physical computer. You must determine:

• Which firewall ports are open?
• What types of traffic are allowed on those ports?

The CA Virtual Systems Monitor includes a Web service to communicate with the management console. The management console needs to send monitoring instructions to its monitoring devices periodically, and the CA Virtual Systems Monitor needs to send files that contain 5-minute aggregate data to the management console. Because the 5-minute data files consist of aggregated data, the network bandwidth that is consumed on the uplink port is minimal.

The following table summarizes the firewall ports that must be open to allow communications between the management console and the CA Virtual Systems Monitor:
