VizQL logs are structured in JSON format, making them easy to search and visualize using a log management solution.
Following are the keys found in a standard VizQL log:
| “ts”: the timestamp for this record | “sess”: the session id |
| “pid”: the process id for this record | “site”: the site name for this record |
| “tid”: the thread id for this record | “user”: the user name |
| “sev”: the severity | “k”: the type (“key”) of the record |
| “req”: the http request id |
I feel Tableau is the most useful and informative tool through which one can solve a lot of complex IT problems.
