Sla Definitions

    • Description: A short description can help with administration.
    • Type: SLA definitions can be made for gateways or gateway server as a whole. When the Gateway SLA option is chosen, the SLA will have rules that apply to that gateway. When Gateway Server SLA is chosen, it will watch the cpu, disk and memory use on that server.
    • General: This option appears when Gateway SLA type is chosen. When the option is chosen, the created SLA will be applied to all gateways.
    • Control Frequency: How often the rules in this SLA will be checked.
