Description: Performs on the search results, a mathematical expression that the user formulates using the Execute execute search syntax (see http://www.japisoft.com/formula/doc/index.html).

Optional Arguments

result1, result2

...

Computes the total of the bytes sent column of the events in log access per status, and displays the total of each status in descending order of the total value. 

Example 2: 

* in log.application_log  | count, sum col_name| interval 1 hour | execute result = column.count * 100 / column.sum ; result | interval 1 hour

Computes the sum of a value in the field col_name in an hourly basis, and computes the percentage of that value out of the total number of events during that time.

Example 3:

* in log.iis log | avg time-taken | group by cs-uristem | execute if (count1 == NULL) THEN (count1 = 0);if (count2 == NULL) THEN (count2 = 0);if (count3 == NULL) THEN (count3 = 0);timetaken = column.avg; if (timetaken > 100 && timetaken < 300) THEN (count1 = count1 + 1);if (timetaken >= 300 && timetaken < 400) THEN (count2 = count2 + 1);if (timetaken >= 400 && timetaken < 500) THEN (count3 = count3 + 1);map = mapput(map,"100",count1);map = mapput(map,"300",count2);map = mapput(map,"400",count3);map as type,value | order by type

Computes the different type of URLs that their average time took between 100-300, 300-400 and 400-500 milliseconds based on the time-taken log field.

Example 4:

* in log.process | avg memory | interval 10 minutes | execute MB = column.Avg; if (result == NULL) then (result=""); diff=0; if (previous != NULL && (MB - previous) > 100) then (diff = MB - previous); key=""; if (diff > 0) then (key = previousTime + ";" + column.time + ";" + format(previous) + ";" + format(MB)); if (diff > 0) then (result = mapput(result, key, format(diff))); previous = MB; previousTime= column.time; result as Start of Time Slot, End of Time Slot , Min Memory, Max Memory, Memory Difference

Computes the difference of an average value in more than 100 units in a 10 minutes time slot - for example increase of more than 100 MB in memory in less than 10 minutes based on performance log.

Example 5:

* in log.LOG_NAME | execute if (total == NULL) then (total = 0); if (count == NULL) then (count = 0);if (column.COLUMN_NAME == COLUMN_VALUE) then (count = count + 1); total = total + 1;(count/total)*100

 Computes the percentages of the value COLUMN_VALUE in the log column COLUMN_NAME out of all events in the log LOG_NAME

• Same query with 10% (for example) threshold for monitoring. I.E. if the value COLUMN_VALUE in the log column COLUMN_NAME out of all events in the log LOG_NAME is greater than 10% it will return a result:

* in log.LOG_NAME | execute if (total == NULL) then (total = 0); if (count == NULL) then (count = 0);if (column.COLUMN_NAME == COLUMN_VALUE) then (count = count + 1); total = total + 1;(count/total)*100 | where value > 10
