Bosun lsstat The average value of a field over time


lsstat returns various summary stats per bucket for the specified field. The field must be numeric in elastic.

rStat can be one of avg, min, max, sum, sum_of_squares, variance, std_deviation.

The rest of the fields behave the same as lscount, except that there is no division based on bucketDuration (since these are summary stats)

$max_querytime_by_minute = lsstat("logstash", "", "env:prod", "querytime", "max", "1m", "1h", "")

The lsstat in this queries the logstash indexes, filters on a field env with the value prod, and gives the max value of querytime for the last hour, in one minute buckets.
