In this section, we'll introduce the following concepts:
accum
Learn how to create a series of running totals for each metric time series.
along
Learn how to control what results are joined based on the value of one or more result fields.
avg
Learn how to calculate the average of all matching time series.
bottomk
Learn how to apply a specified aggregation function to the time series that match the query selector.
count
Learn how to count the total number of time series that match the query.
delta
Learn how to compute the backward difference at each data point in the time series.
eval
Learn how to evaluate a time series based on a user-specified arithmetic or mathematical function.
ewma
Learn how to compute an EWMA on the data points returned by the query for the selected time range.
fillmissing
Learn how to fill empty time slices in metric query results with a derived data point.
filter
Learn how to limit the results returned by a metric query.
histogram_quantile
Learn how to calculate the φ-quantile from the buckets of a histogram.
in
Learn how to use this operator in a metrics query selector as shorthand for multiple OR conditions.
max
Learn how to calculate the maximum value of the time series that match the query.
min
Learn how to calculate the minimum value of the time series that match the query.
outlier
Learn how to identify metrics data points that are outside the range of expected values.
parse
Learn how to parse the specified field to create new fields to use in the metrics query.
predict
Learn how to take a single time series metric to predict future values.
pct
Learn how to calculate the nth percentile of values of the input series for each time interval.
quantize
Learn how to use this operator to control Sumo’s quantization behavior.
rate
Learn how to calculate the per-second rate of change between consecutive data points.
stddev
Learn how to measure the magnitude of deviations between the values in a time series.
sum
Learn how to calculate the sum of the metrics values that match the query.
timeshift
Learn how to shift the time series from your metrics query by a specified period of time.
topk
Learn to apply a specified aggregation function to the time series that match the query selector.
where
Learn how to filter out entire time series, or individual data points within a time series.
