Hi Splunk support,

I have a set of log file which name as below: (today is 20170723)
application_20170721.log
application_20170722.log
application_20170723.log

In unix, it should be like application_date +%Y%m%d.log

in order to search the latest log file, what should the search command.

so that sth can be like source="application_date +%Y%m%d.log"

How is this search sentence?

(your search)  [| tstats max(_time) as wk_time where sourcetype=(your sourcetype)|eval source="application_"+strftime(wk_time,"%Y%m%d")+".log"| fields source]

OR
where sourcetype=(your sourcetype)→where source="application_*.log"

Hi oolongcat,
you could use

[monitor://your_path/application_*.log]
index = your_index
sourcetype = your_sourcetype
disabled = 0
ignoreOlderThan = 2d

In this way you have all events of last two days (or a different time range) and not older.

Bye.

Hi Cusello,

Thanks for you reply.

your way seems will ignore all the log file which older than 2 days, but this is not what I want.

Is there any way like as below:

[search source="application_" +strftime(time(),"%Y%m%d") + ".log"]
