Abstract

Examples disclosed herein relate to a method comprising monitoring a first condition corresponding to a first parameter in a first database. The first database is configured to operate a first switch operating traffic on a network and the first database periodically synching with a second database. The method may also include monitoring a second parameter, corresponding to the first parameter, on the second database. The second database may be configured to operate a second switch on the network and the first switch and the second switch configured to operate traffic on the network. The method may also include determining that there is a deviation between the first and second that exceeds a threshold amount and transmitting an alert containing the deviation.

First claim

The invention claimed is:

1. A method, comprising:
storing, by a first switch, a first set of parameter values in a first time-series database of the first switch, wherein the first switch is configured to operate in a network based on the first set of parameter values;
monitoring the first set of parameter values in the first time-series database based on a set of conditions indicating the operation of the first switch in the network;
receiving, periodically, a second set of parameter values of a second time-series database of a second switch;
synchronizing the first time-series database with the second time-series database based on the second set of parameter values;
determining, based on the synchronization, that a deviation between a first parameter value in the first time-series database and a second parameter value of the second set of parameter values exceeds a threshold, wherein the first and second parameter values indicate a same network configuration; and
generating an alert indicating the deviation.

2. The method of claim 1 , further comprising:
performing an operation to correct the deviation between the first and second parameter values.

3. The method of claim 1 , further comprising:
retrieving, from the first time-series database, respective historical values corresponding to the first and second parameter values;
determining a historical comparison between historical values corresponding the first parameter value and historical values corresponding to the second parameter value; and
comparing the historical comparison to the deviation.

4. The method of claim 1 , wherein the first parameter value indicates a first count of a type of entities in the network, the second parameter value indicates a second count of the type of entities in the network, and the deviation is a difference between the first count and the second count.

5. The method of claim 1 , wherein the first parameter value indicates a first route between a first device and a second device in the network, and the second parameter value indicates a second route between the first and the second devices, and wherein the deviation is a difference in the first route and the second route.

6. The method of claim 1 , further comprising maintaining, for the first switch, a subscription to the second time-series database for receiving data related to the second parameter value.

7. The method of claim 1 , wherein both the first and the second switches are configured, via the first and second time-series databases, respectively, to actively manage the network.

8. The method of claim 1 , wherein the first and the second switches are configured to appear as a virtual switch.

9. The method of claim 1 , comprising:
receiving a user generated script identifying the first parameter value;
determining that the second parameter value corresponds to the first parameter value based on the user generated script; and
executing the user generated script on the first switch.

10. A system, comprising:
a processor,
a memory device;
a storage device configured to store a first set of parameter values in a first time-series database, wherein the system is configured to operate in a network based on the first set of parameter values;
a monitor configured to:
monitor the first set of parameter values in the first time-series database based on a set of conditions indicating the operation of the first switch in the network;
receive, periodically, a second set of parameter values of a second time-series database of a second system; and
synchronizing the first time-series database with the second time-series database based on the second set of parameter values;

a deviation handler configured to determine, based on the synchronization, that a deviation between a first parameter value in the first time-series database and a second parameter value of the second set of parameter values exceeds a threshold, wherein the first and second parameter values indicate a same network configuration; and
an alert module configured to generate an alert indicating the deviation.

11. The system of claim 10 , further comprising:
an operation module configured to perform an operation to correct the deviation between the first and second parameter values.

12. The system of claim 10 , further comprising:
an historical value handler to:
retrieve, from the first time-series database, respective historical values corresponding to the first and second parameter values;
determine a historical comparison between historical values corresponding to the first parameter value and historical values corresponding to the second parameter value; and
compare the historical comparison to the deviation.

13. The system of claim 10 , further comprising:
a script handler configured to:
receive a user generated script identifying the first parameter value;
determine that the second parameter value corresponds to the first parameter value based on the user generated script; and
execute the user generated script on the system.

14. The system of claim 10 , wherein the first parameter value indicates a first count of a type of entities in the network, the second parameter value indicates a second count of the type of entities in the network, and the deviation is a difference between the first count and the second count.

15. The system of claim 10 wherein the first parameter value indicates a first route between a first device and a second device in the network, the second parameter value indicates a second route between the first and the second devices, and wherein the deviation is a difference in the first route and the second route.

16. A non-transitory machine-readable storage medium encoded with instructions, the instructions executable by a processor of a network system to cause the network system to:
store a first set of parameter values in a first time-series database of the network system, wherein the network system is configured to operate in a network based on the first set of parameter values;
monitor the first set of parameter values in the first time-series database based on a set of conditions indicating the operation of the first switch in the network;
receive, periodically, a second set of parameter values of a second time-series database of a second network system;
synchronize the first time-series database with the second time-series database based on the second set of parameter values;
determine, based on the synchronization, that a deviation between a first parameter value in the first time-series database and a second parameter value of the second set of parameter values exceeds a threshold, wherein the first and second parameter values indicate a same network configuration; and
generate an alert indicating the deviation.

17. The non-transitory machine-readable storage medium of claim 16 , wherein the instructions executable by the processor of the network system to cause the network system to maintain a subscription to the second time-series database for receiving data related to the second parameter value.

18. The non-transitory machine-readable storage medium of claim 16 , wherein both the first and the second switches are configured, via the first and second time-series databases, respectively, to actively manage the network.

19. The non-transitory machine-readable storage medium of claim 16 , wherein the first and the second switches are configured to appear as a virtual switch.

20. The non-transitory machine-readable storage medium of cla
