round function doesn't work with timechart but does with table

zacksoft — Fri, 11 May 2018 13:25:52 GMT

This following doesn't work. I don't see the decimals limiting to two digits.
| eval n=round(var5,2) | timechart span=1d avg(n) as avg_count by host

But when I do this,
| eval n=round(var5,2) | table var5
It works.

I tested that in timechart command neither round nor ceiling function is working.
Any suggestion on how to make it work?
Or something wrong with my Splunk set up.

That's because you are rounding the value in n, but you're not rounding the result of the avg() function.

So you need to do:

| eval n=round(var5,2) | timechart span=1d eval(round(avg(n),2)) as avg_count by host

Could you help how to use ceiling in the same search.

Have a look at the search reference for how to use the timechart command. Especially on how to use eval functions: http://docs.splunk.com/Documentation/Splunk/7.1.0/SearchReference/Timechart

If you want to apply ceiling(), just put that in instead of round(). For example (leaving the var5 value as is now, although you can already apply ceiling to that as well if you want):

| eval n=var5 | timechart span=1d eval(ceiling(avg(n)) as avg_count by host

I tried it. But ceiling function won't work. It says
| eval n=var5 | timechart span=1d eval(ceiling(avg(n)) as avg_count by host
Mismatched quotes and/or parenthesis.

and with this | eval n=var5 | timechart span=1d eval(ceiling(avg(n))) as avg_count by host
The eval expression has no fields: 'ceiling(avg(n))'

@zacksoft try the following:

<yourBaseSearch>
| timechart span=1d eval(avg(var5)) as avg_count by host
| foreach * [eval "<<FIELD>>"=ceiling('<<FIELD>>')]

PS: I have taken out | eval n=round(var5,2)
