Network Traffic Appliance for Triggering Augmented Data Collection on a Network Based on Traffic Patterns
A method and system for increasing the collection of network traffic data in a network based on the occurrence of predetermined criteria. A network appliance manages network traffic in the network and passes data traffic on the network. Network traffic data is collected based on the data traffic passing through the network appliance at a normal level. It is determined whether the network traffic data indicates an abnormal condition. The collection of network traffic data is increased through the network traffic appliance when an abnormal condition is detected. The network traffic data from the increased collection is stored in a memory device.
1 . A method of adjusting network data management in a network appliance coupled to devices in a network, the network appliance passing data traffic on the network, the method comprising:
collecting network traffic data based on the data traffic passing through the network appliance at a normal level;
determining whether the network traffic data indicates an abnormal condition;
increasing the collection of network traffic data through the network appliance when an abnormal condition is detected; and
storing the network traffic data from the increased collection in a memory device.
2 . The method of claim 1 , further comprising:
sending the network traffic data from the increased collection to a central management device;
analyzing the network traffic data via the central management device to determine the abnormal condition.
3 . The method of claim 1 , further comprising monitoring the increased collection of network traffic data to determine the cessation of the abnormal condition.
4 . The method of claim 3 , further comprising returning the collection of network traffic data to the normal level when the abnormal condition has ceased.
5 . The method of claim 3 , further comprising returning the collection of network traffic data to the normal level after a predetermined time.
6 . The method of claim 1 , wherein the network traffic data from the increased collection is removed from the memory device after the abnormal condition ceases.
7 . The method of claim 1 , wherein the increased data collection includes network traffic data collected under the Netflow protocol.
8 . The method of claim 1 , wherein the increased data collection includes at least one of network traffic data from a router, a network device or SNMP data.
9 . The method of claim 2 , wherein the central management device controls a second network traffic appliance monitoring traffic on a second network, the increased data collection coming exclusively from the first network traffic appliance.
10 . A traffic management system for regulating network traffic between computing devices in a network, the system comprising:
a collection module for collecting network traffic data;
a storage device storing network traffic data; and
a data analysis module coupled to the data collector module, the data analysis module monitoring the network traffic data from the collection module; and
wherein the collection module increases collection of network traffic data when an abnormal condition is detected by the data analysis module.
11 . The system of claim 10 , wherein the collection module and the data analysis module are in a network traffic appliance coupled to the network.
12 . The system of claim 10 , further comprising:
a network traffic appliance for managing network traffic data on a another network; and
wherein the collection module and the data analysis module are in a central management device coupled to the network traffic appliance.
13 . The system of claim 12 , wherein the central management device analyzes the network traffic data to determine the abnormal condition.
14 . The system of claim 10 , wherein the collection module monitors the increased collection of network traffic data to determine the cessation of the abnormal condition.
15 . The system of claim 14 , wherein collection of network traffic data is returned to the normal level when the abnormal condition has ceased.
16 . The system of claim 14 , further comprising returning the collection of network traffic data to the normal level after a predetermined time.
17 . The system of claim 10 , wherein the network traffic data from the increased collection is removed from the memory device after the abnormal condition ceases.
18 . The system of claim 10 , wherein the increased data collection includes network traffic data collected under the Netflow protocol.
19 . The system of claim 10 , wherein the increased data collection includes at least one of network traffic data from a router, a network device or SNMP data.
