combining the one or more logs or log-related information obtained from the logging systems with one or more additional logs or additional log-related information obtained from the cache system.

9 . The method of claim 1 , wherein:

the user query is received using a specified query syntax; and

the method further comprises converting the specified query syntax into multiple query syntaxes used by two or more of the logging systems.

different ones of the responses from the logging systems are received in different syntaxes; and

the method further comprises converting the different responses into a specified response syntax.

11 . The method of claim 1 , further comprising:

authenticating the user; and

sending at least one authentication token to at least one of the logging systems to enable retrieval of information from the at least one of the logging systems.

12 . The method of claim 1 , wherein pre-populating the cache system comprises:

executing a background task; and

using the background task:

periodically querying the multiple logging systems for newer logs or log-related information within the most-recent specified time period; and

pre-populating the first cache with the newer logs or log-related information; and

wherein the most-recent specified time period includes one or more hours or one or more days.

13 . A system comprising:

at least one processing device configured to:

pre-populate a cache system using a subset of logs or log-related information from multiple logging systems associated with different computing or networking systems, wherein the cache system includes a first cache and a second cache;

receive a user query identifying one or more criteria associated with the logs or log-related information;

determine whether one or more logs or log-related information satisfying the one or more criteria is contained in the cache system;

in response to determining that the one or more logs or log-related information satisfying the one or more criteria is not contained in the cache system, send queries identifying the one or more criteria to the multiple logging systems;

obtain responses from the logging systems, at least some of the responses containing one or more logs or log-related information satisfying the one or more criteria;

present the one or more logs or log-related information satisfying the one or more criteria to a user; and

move at least some of the subset of logs or log-related information from the first cache to the second cache based on age of the subset of logs or log-related information;

wherein the at least one processing device is configured to pre-populate the cache system prior to receiving the user query; and

wherein the at least one processing device is configured to pre-populate the cache system periodically over time at a specified time interval in order to include, in the cache system, logs or log-related information from the multiple logging systems within a most-recent specified time period.

14 . The system of claim 13 , wherein the at least one processing device is configured to obtain at least a portion of the one or more logs or log-related information from the cache system in response to determining that the one or more logs or log-related information satisfying the one or more criteria is contained in the cache system.

15 . The system of claim 13 , wherein the at least one processing device is configured to pre-populate the cache system by obtaining the logs or log-related information from the logging systems within the most-recent specified time period and storing the obtained logs or log-related information in the first cache of the cache system.

16 . The system of claim 13 , wherein the at least one processing device is configured to pre-populate the cache system by executing a background task without user interaction.

17 . The system of claim 13 , wherein:

the first and second caches include different storage locations;

to pre-populate the cache system, the at least one processing device is configured to store different data in the different storage locations; and

the different storage locations are associated with at least one of: different query capabilities and different costs.

18 . The system of claim 13 , wherein the at least one processing device is further configured to combine the one or more logs or log-related information obtained from the logging systems with one or more additional logs or additional log-related information obtained from the cache system.

19 . The system of claim 13 , wherein the at least one processing device is configured to at least one of:

receive the user query using a specified query syntax and convert the specified query syntax into multiple query syntaxes used by two or more of the logging systems; and
