Metrics Operators

This guide describes Sumo Logic metrics operators and provides usage examples.

Guide contents​

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.
