Abstract

In one embodiment, a computing device determines one or more profiles of respective wireless network issues, each of the one or more profiles having a set of associated parameters. By monitoring wireless conditions in a particular wireless network, the computing device may then detect that the wireless conditions exhibit trigger conditions correlated to a particular set of associated parameters for a particular profile of a particular wireless network issue. In response to detecting that the wireless conditions exhibit trigger conditions, the computing device may then capture and store data regarding the wireless conditions, accordingly.

First claim

What is claimed is:

1. A method, comprising:
determining, by a computing device, one or more profiles of respective wireless network issues that are reported by users of wireless networks, each of the one or more profiles having a) a set of associated parameters are indicative of a particular wireless network issue and b) data capture and storage requirements associated with the particular wireless network issue;
monitoring, by the computing device, wireless conditions in a particular wireless network of the wireless networks;
detecting, by the computing device, that the wireless conditions exhibit trigger conditions are correlated to a particular set of associated parameters of a particular profile of the one or more profiles, wherein the particular profile is associated with a given wireless network issue, further wherein the trigger conditions comprise a probability threshold that conditions of the particular wireless network will result in the given wireless network issue and storage availability of the computing device; and
capturing and storing, by the computing device and according to data capture and storage requirements of the particular profile, data regarding the wireless conditions in response to detecting that the wireless conditions exhibit the trigger conditions, wherein the data regarding the wireless conditions is contextually specific data for the given wireless network issue because of the data capture and storage requirements of the particular profile.

2. The method as in claim 1 , wherein the set of associated parameters for the one or more profiles comprise one or both of issue-specific parameters and general parameters.

3. The method as in claim 1 , wherein the trigger conditions are exhibited based on surpassing the probability threshold that conditions of the wireless network will result in a given wireless network issue.

4. The method as in claim 3 , further comprising:
adjusting the probability threshold based on the storage availability.

5. The method as in claim 1 , further comprising:
storing the data with a decay time specifically associated with the particular wireless network issue.

6. The method as in claim 1 , further comprising:
capturing the data until the wireless conditions no longer exhibit the trigger conditions.

7. The method as in claim 1 , further comprising:
capturing the data for a given time.

8. The method as in claim 1 , further comprising:
weighting individual parameters of the set of associated parameters for the one or more profiles of respective wireless network issues.

9. The method as in claim 8 , wherein weighting is performed by one or both of machine learning weighting and manual weight input.

10. The method as in claim 1 , further comprising:
updating parameters of the set of associated parameters for the one or more profiles of respective wireless network issues in response to one or more changes in the wireless network.

11. The method as in claim 1 , further comprising:
separating the stored data into groups based on the wireless network issue causing the capturing.

12. A tangible, non-transitory, computer-readable medium storing program instructions that cause a computing device to execute a process, comprising:
determining one or more profiles of respective wireless network issues that are reported by users of wireless networks, each of the one or more profiles having a) a set of associated parameters are indicative of a particular wireless network issue and b) data capture and storage requirements associated with the particular wireless network issue;
monitoring wireless conditions in a particular wireless network of the wireless networks;
detecting that the wireless conditions exhibit trigger conditions are correlated to a particular set of associated parameters of a particular profile of the one or more profiles, wherein the particular profile is associated with a given wireless network issue, further wherein the trigger conditions comprise a probability threshold that conditions of the particular wireless network will result in the given wireless network issue and storage availability of the computing device; and
capturing and storing, according to data capture and storage requirements of the particular profile, data regarding the wireless conditions in response to detecting that the wireless conditions exhibit the trigger conditions, wherein the data regarding the wireless conditions is contextually specific data for the given wireless network issue because of the data capture and storage requirements of the particular profile.

13. The computer-readable medium as in claim 12 , wherein the set of associated parameters for the one or more profiles comprise one or both of issue-specific parameters and general parameters.

14. The computer-readable medium as in claim 12 , wherein the trigger conditions are exhibited based on surpassing the probability threshold that conditions of the wireless network will result in a given wireless network issue.

15. An apparatus, comprising:
one or more network interfaces to communicate with a computer network;
a processor coupled to the network interfaces and configured to execute one or more process; and
a memory configured to store a process executable by the processor, the process when executed configured to:
determine one or more profiles of respective wireless network issues that are reported by users of wireless networks, each of the one or more profiles having a) a set of associated parameters are indicative of a particular wireless network issue and b) data capture and storage requirements associated with the particular wireless network issue;
monitor wireless conditions in a particular wireless network of the wireless networks;
detect that the wireless conditions exhibit trigger conditions are correlated to a particular set of associated parameters of a particular profile of the one or more profiles, wherein the particular profile is associated with a given wireless network issue, further wherein the trigger conditions comprise a probability threshold that conditions of the wireless network will result in the given particular wireless network issue and storage availability of the apparatus; and
capture and store, according to data capture and storage requirements of the particular profile, data regarding the wireless conditions in response to detecting that the wireless conditions exhibit the trigger conditions, wherein the data regarding the wireless conditions is contextually specific data for the given wireless network issue because of the data capture and storage requirements of the particular profile.

16. The apparatus as in claim 15 , wherein the set of associated parameters for the one or more profiles comprise one or both of issue-specific parameters and general parameters.

17. The apparatus as in claim 15 , wherein the trigger conditions are exhibited based on surpassing the probability threshold that conditions of the wireless network will result in a given wireless network issue.
