days information

roopeshetty — Tue, 21 Jan 2020 09:51:59 GMT

Hi Guys,

We have a field by name “Validity” which shows the validity date as below for different products;

Validity : Dec 19, 2021

Validity : Dec 11, 2022

Validity : Mar 14, 2023

Validity : Aug 24, 2021

Here we need to create a field by name “DaysRemaining” which will have the values as number of days left from today by deducting the current date (of host running splunk ) with that Validity date. We will run that query once in every day so that the Days remaining will change every day.

Can someone please help us with the splunk query?

Finding the difference between timestamps requires first converting them to epoch (integer) form. Try this:

... | eval DaysRemaining = (now() - strptime(Validity, "%b %d, %Y")) / 86400

Hi @roopeshetty,
you have to convert dates in epochtime and then use eval to subtract:

your_search
| eval diff_days=(strptime(Validity,"%b %d,%Y")-now())/3600/24
| table Validity diff_days

Eventually, you can round.

Ciao.

Add this to the bottom of existing search:

... | eval Validity = strptime(Validity, "%b %d, %Y")
| fieldformat Validity = strftime(Validity, "%b %d, %Y")
| eval DaysRemaining = now() - Validity
| fieldformat DaysRemaining = tostring(DaysRemaining, "duration")
