Types of Data Included in 15-Minute Data
The types of data that are collected and stored as 15-minute resolution data by default include:
- Total IP, TCP, and UDP traffic in and out of each interface
- Flows and bytes of flow traffic in and out of each interface
- Total flow traffic from each router
- Top 100 protocols in and out of each interface
- Traffic to and from the top 50 IP hosts
- Traffic for the top 50 IP conversations
- Traffic to and from the top 10 hosts for the top 20 protocols
- Traffic for the top 10 conversations for the top 20 protocols
- Total IP traffic in and out of each interface for each ToS value
- Traffic for the top 20 protocols for the top 5 non-zero ToS values
- Traffic for the top 10 hosts for the top 5 non-zero ToS values
- Traffic for the top 10 conversations for the top 5 non-zero ToS values
- Top 100 source and destination AS values
- Top 20 Nexthop addresses for each AS value
Note: When you use Reserved Seating, the top protocols can be collected according to the priorities you establish rather than according to traffic volume.
The collected data is stored as follows:
- Protocol data: 15-minute granularity for the past 13 months
- Host and conversation data: 15-minute granularity for the past 2 months
- Interface summary data: 15-minute granularity for the past 13 months
- ToS summary data: 15-minute granularity for the past 13 months
- Top protocols for the top ToS values: 15-minute granularity for the past 13 months
- Top hosts and conversations for the top ToS values: 15-minute granularity for the past 2 months
Note: While 15-minute data reflect totals for each interface, Enterprise Overview data reflects totals for all interfaces. For example, Enterprise Overview data includes the Top N protocols for all interfaces. The 15-minute data includes the Top N protocols for each interface.
