How to search dynamic field in Splunk?

Hi,

I have a lookup table where column names are with weekdays (like monday, tuesday, wednesday,...) and have possible values as 1 and 0 only.

What I want to achieve..

...some query | eval day=strftime(now(),"%A") | where 'day'=1

but this doesn't seems to be working. Any idea how to search dynamic fields.

 

Thanks

Hi @sbhatnagar88,

which are the lookup fields?

if they are:

  • day (like monday, tuesday, wednesday,...)
  • value (0 or 1)

your search must be different:

...some query 
| eval day=strftime(now(),"%A") 
| search [ | inputlookup your_lookup.csv WHERE value="1" | fields day ]
| ...

put attention that the "day" values from the main search and from the lookup are the same.

Ciao.

Hi  @gcusello ,

My search itself begins with searching from KV lookup.  and that kv lookup have column name with day name something like

host    Type  monday  tuesday  wednesday  thursday   friday   saturday  sunday

ABC      X         1                 1                  1                     1                   1                 0              0

DEF       Y          0                0                  0                     0                    0                  1              1

I am using below query..

| inputlookup test | search type="ABC"  | eval day=strftime(now(),"%A")   | where 'day'=1

Basically I want to search dynamic day from my lookup.

Hi @sbhatnagar88,

I don't thing that's possible to have what you would, I think that you should think to a different structure for your lookup, e.g.:

  • host,
  • day,
  • value,

then you could run something like this:

| inputlookup test 
| search host="ABC"  
| search day=strftime(now(),"%A") AND value=1

Ciao.
