Auto update of sensor configuration
Systems, methods, and computer-readable media for updating configurations in sensors deployed in multi-layer virtualized environments. In some examples, a system can track information of sensors and collectors in the network. In response to determining that a specific collector becomes unavailable (e.g., the specific collector is down, offline or becomes unsupported), the system can determine affected sensors corresponding to the specific collector, determine a new collector among active collectors of the network for each of the affected sensors, and dynamically update configuration and settings of the affected sensors to maintain proper collector-to-sensor mappings and other settings on the affected sensors.
1. A method comprising:
determining that a collector from a plurality of collectors is unavailable;
receiving sensor information from a plurality of sensors of a network;
identifying a sensor of the plurality of sensors that corresponds to the collector from the sensor information;
reassigning the sensor to another collector from the plurality of collectors; and
causing the sensor to update a configuration of the sensor based on collector information associated with the another collector.
2. The method of claim 1 , further comprising:
determining loads on the plurality of collectors operating in the network based on network data for the plurality of collectors; and
reassigning the sensor to the another collector of the plurality of collectors based on the loads on the plurality of collectors.
3. The method of claim 1 , further comprising:
identifying a health of the collector with respect to operation of the collector in the network; and
determining that the collector is unavailable based on a comparison of the health of the collector to one or more threshold levels of collector health.
4. The method of claim 1 , further comprising:
identifying that a communication error exists between the collector and one or more sensors associated with the collector; and
determining that the collector is unavailable based on existence of the communication error.
5. The method of claim 1 , wherein the sensor information is received as part of sensor reports generated by the plurality of sensors.
6. The method of claim 1 , wherein collectors of the plurality of collectors are configured to collect flows travelling through corresponding sensors of the plurality of sensors.
7. The method of claim 6 , wherein respective sensor information of the corresponding sensors is gathered by the collectors through the flows.
8. The method of claim 1 , wherein the sensor information of the plurality of sensors comprises location information, characteristic information, and context information of the plurality of sensors.
9. The method of claim 1 , further comprising:
determining that a new collector is added to the network;
accessing collector information of the new collector;
determining that the new collector is active based on the collector information; and
reassigning the sensor to the new collector based on the new collector being active.
10. A system comprising:
one or more processors; and
a computer-readable medium comprising instructions stored therein, which when executed by the one or more processors, cause the one or more processors to:
determine that a collector from a plurality of collectors is unavailable;
receive sensor information from a plurality of sensors of a network;
identify a sensor of the plurality of sensors that corresponds to the collector from the sensor information;
reassign the sensor to another collector from the plurality of collectors; and
cause the sensor to update a configuration of the sensor based on collector information associated with the another collector.
11. The system of claim 10 , wherein the instructions, which when executed by the one or more processors, further cause the one or more processors to:
determine loads on the plurality of collectors operating in the network based on network data for the plurality of collectors; and
reassign the sensor to the another collector of the plurality of collectors based on the loads on the plurality of collectors.
12. The system of claim 10 , wherein the instructions, which when executed by the one or more processors, further cause the one or more processors to:
identify a health of the collector with respect to operation of the collector in the network; and
determine that the collector is unavailable based on a comparison of the health of the collector to one or more threshold levels of collector health.
13. The system of claim 10 , wherein the instructions, which when executed by the one or more processors, further cause the one or more processors to:
identify that a communication error exists between the collector and one or more sensors associated with the collector; and
determine that the collector is unavailable based on existence of the communication error.
14. The system of claim 10 , wherein the sensor information is received as part of sensor reports generated by the plurality of sensors.
15. The system of claim 10 , wherein collectors of the plurality of collectors are configured to collect flows travelling through corresponding sensors of the plurality of sensors.
16. The system of claim 15 , wherein respective sensor information of the corresponding sensors is gathered by the collectors through the flows.
17. The system of claim 10 , wherein the sensor information of the plurality of sensors comprises location information, characteristic information, and context information of the plurality of sensors.
18. The system of claim 10 , wherein the instructions, which when executed by the one or more processors, further cause the one or more processors to:
determine that a new collector is added to the network;
access collector information of the new collector;
determine that the new collector is active based on the collector information; and
reassign the sensor to the new collector based on the new collector being active.
19. A non-transitory computer-readable storage medium comprising instructions stored therein, which when executed by one or more processors, cause the one or more processors to:
determine that a collector from a plurality of collectors is unavailable;
receive sensor information from a plurality of sensors of a network;
identify a sensor of the plurality of sensors that corresponds to the collector from the sensor information;
reassign the sensor to another collector from the plurality of collectors; and
cause the sensor to update a configuration of the sensor based on collector information associated with the another collector.
20. The non-transitory computer-readable storage medium of claim 19 , wherein the instructions, which when executed by the one or more processors, further cause the one or more processors to:
determine that a new collector is added to the network;
access collector information of the new collector;
determine that the new collector is active based on the collector information; and
reassign the sensor to the new collector based on the new collector being active.
