Is it possible to run a search on a log file that would pull the log lines above and below the returned result? I want to look in the Directory for people called Alex, plus 100 names above them and 100 names below them in the alphabetical list.
Splunk works on time series data. If your log files are time series based, you can do a temporal filter for events within + or - X time of the core event your are looking for.
There is no baseline show me "+/-100 events from this time, in alphabetical order" type of command.
Depending on what you are wanting to do, you could find your person Named alex, sort 201 names between that event and filter alphabetically. But again, this is not time series based data, and doesnt fit a Splunk use case very well.
