This topic gives you broad guidelines to determine the size of your platform.

Architecture

First, use the guildelines described on the Architectures page to determine the type of architecture you need.

Characteristics of the servers

• The more services you monitor, the more CPU you need.

• The space used to store collected performance data depends on several criteria:

  • Frequency of checks
  • Number of checks
  • Retention time
  • Average number of metrics per service

• The number of users simultaneously connected to the interface of the central/remote server has an impact on performance. If a lot of users will have to log in to the Sipmon interface at the same time, you will need more CPU.

The following data is meant for:

• An average of 10 services per host.
• Data is collected every 5 minutes.
• The retention period is 12 months.
• Each service has on average 8 metrics.

You need to adapt the following figures to your actual values. Bear in mind that you may need to adjust the size of your platform as you add more hosts over time.

Network flows

If you have firewalls or security equipments in place, check the table of network flows.
