in a Splunk Dashboard, how do you calculate the time difference between now and start time ?

Hi all,

I have a Splunk dashboard in which I have to divide my total by seconds (Please refer below 3600). Instead of hard coding, I have to do a divide by difference between start time and now .

| eval TPS=Round((Total/**3600**),2) 

I.e., if I select and search for time range between 03/05/2019 04:00:00 AM to 03/05/2019 06:00:00 AM , it should return a value which i can substitute using a variable in the below eval function.

| eval TPS=Round((Total/**some_variable**),2) 

Any help is much appreciated .!!!!

thanks in advance.

@jagadeeshvenkatesh1,

now() - $your_time_token.earliest$

updated:

|eval starttime=if(match("$field1.earliest$","^(\d+)"),"$field1.earliest$",relative_time(now(),"$field1.earliest$"))
|eval TPS=Round((Total/(now() - starttime)),2)

okie, thats because you might be using relative time (-1d,-1m etc).

Try this then

|eval starttime=if(match("$field1.earliest$","^(\d+)"),"$field1.earliest$",relative_time(now(),"$field1.earliest$"))
| eval TPS=Round((Total/(now() - starttime)),2)
