Splunk Search

Regex for changing date

Hi,

I want to check daily if my file generated successfully. The filename is prefixed by date so e.g.

3 march i'll have a filename like: 20160302-myfile
2 march - 20160301-myfile

I retain the files in folder for 3 months so just using *-myfile doesn't work for me.

Can splunk regex autoincrement the date everyday?

Try something like this

sourcetype=xyz "/my folder/ mysubfolder" [| gentimes start=-1 | eval search=strftime(now(),"%Y%m%d') | table search ] 

The subsearch will generate a value in the format %Y%m%d (2010303 for today) and return the text value of it to main search.

So, the data is ingested already and you want to alert OR check if you received file for today (or Yesterday) using Splunk search?

Yes my log does show it. e.g.

today's log will show

/my folder/ mysubfolder 20160302-myfile.zip 20160301-myfile.zip .....

I need the search string to search on:

sourcetype=xyz "/my folder/ mysubfolder" 20160301 (this variable should change automatically everyday)
