Getting full result in join/append

[nkumar6]

I have a index, where i store values of items and their count (pulled from SQL DB). I run a search to return me items of today and a sub search to return items of last week same day(-7d@d to -6d@d and @d to now).

for example:
Todays data
ITEMS COUNT
a1 2
a2 3
a3 4

LAST week data :
ITEMS COUNT
a1 5
a2 10
a4 8

I also want to run a calculation to calculate difference of both count.
So the expected would be:

ITEMS COUNT_TODAY COUNT_LASTWEEK Difference
a1 2 5 -3
a2 3 10 -7
a3 4 4
a4 8 -8

I have already tried append with stats, appendcols, join, but i always miss-out some data.
In append ans stats i can't do the calculation part, in appendcols lastweekdata merges with wrong set of todays data, and in join i miss out the blank part. Calculation for null values can be ignored, but if done it would be helpful.

Thanks in advance.

Hi , how about it?
When searching, please use first @woodcook 's search text.

[nkumar6]

While executing your suggestion i get error as "Error in 'makeresults' command: This command must be the first command of a search".

Did I miss out something?

[to4kawa]

makeresults

This command must be written at the beginning of the search.

When searching, please use first @woodcook 's search text.

It was a remark when actually applying it to your query ...

[nkumar6]

I don't get any error but nor do I get any result. and eval ITEM="a".(random() % 5 + 1) wouldn't work in my case, as it was just example I used for a1,a2,a3 etc...

 | makeresults count=2
 | streamstats count
 | eval _time = if (count==2,relative_time(_time,"+1d@d"), relative_time(_time,"-8d@d")) 
 | makecontinuous span=5m

 | eval ITEMS="a".(random() % 5 + 1)
 | table _time ITEMS

please paste this query and search, check it.
This query is aim to create sample data.

and

| eval week=case(strftime(_time,"%d")==strftime(now(),"%d"),"COUNT_TODAY",strftime(_time,"%d")==strftime(relative_time(now(),"-7d@d"),"%d"),"COUNT_LASTWEEK")
 | chart count over ITEMS by week
 | eval Difference= COUNT_TODAY - COUNT_LASTWEEK
 | table ITEMS COUNT_TODAY COUNT_LASTWEEK Difference

This query is the logic of calculate what you want .

_time ITEM 

If your log has two fields in this way, my logic should work as well.

Hi @to4kawa ,
can you help me with this, I am still failing to do so, neither I can find any other example like this.

[woodcock]

You need the leading pipe as in | makeresults ...

I did like this
index=abc AND sourcetype=xyz ((earliest=-8d@d latest=-7d@d) OR (earliest=@d latest=now))
| makeresults count=2
| streamstats count
| eval _time = if (count==2,relative_time(_time,"+1d@d"), relative_time(_time,"-8d@d"))
| makecontinuous span=5m
| where strftime(_time,"%d")==strftime(now(),"%d") OR strftime(_time,"%d")==strftime(relative_time(now(),"-7d@d"),"%d")
| eval ITEM="a".(random() % 5 + 1)
| table _time ITEM
| eval week=case(strftime(_time,"%d")==strftime(now(),"%d"),"COUNT_TODAY",strftime(_time,"%d")==strftime(relative_time(now(),"-7d@d"),"%d"),"COUNT_LASTWEEK")
| chart count over ITEM by week
| eval Difference= COUNT_TODAY - COUNT_LASTWEEK
| table ITEM, COUNT_TODAY, COUNT_LASTWEEK, Difference

[woodcock]

Like this:

index="YouShouldAlwaysSpecifyAnIndex" AND sourcetype="AndSourcetypeToo" ((earliest=-8d@d latest=-7d@d) OR (earliest=@d latest=now))
| timechart limit=0 useother=false cont=f span=1d count BY items
| where _time = relative_time(now(), "-8d@d") OR _time = relative_time(now(), "@d")
| untable _time items count
| eval _time = if(_time == relative_time(now(), "-8d@d"), "LASTWEEK", "TODAY")
| xyseries items _time count
| eval DIFFERENCE = TODAY - LASTWEEK

Here is a run-anywhere example:

|tstats count WHERE index="*" AND sourcetype="*" ((earliest=-8d@d latest=-7d@d) OR (earliest=@d latest=now)) BY sourcetype _time span=1h
| timechart limit=0 useother=false cont=f span=1h count BY sourcetype
| where _time = relative_time(now(), "-8d@d") OR _time = relative_time(now(), "@d")
| untable _time sourcetype count
| eval _time = if(_time == relative_time(now(), "-8d@d"), "LASTWEEK", "TODAY")
| xyseries sourcetype _time count
| eval DIFFERENCE = TODAY - LASTWEEK

[woodcock]

Just try my top answer but change YouShouldAlwaysSpecifyAnIndex to your actual index value and AndSourcetypeToo to your actual sourcettype value. You have had working answers for days now.
