Sum over time by label. Apr 20, 2022 · You need to use a function to extract the number of searches in a specific time window. g: This will give you the number of searchTerm grouped by bot_guides_failed_total in a 5 minutes time window. Loki defines Time Durations with the same syntax as Prometheus. The aggregation is applied over a time duration. e. The only way to construct a range vector in PromQL is by appending a bracketed duration to a vector selector. In Grafana Loki, the selected range of samples is a range of selected log or label values. See this issue for details. Log range aggregations Dec 3, 2021 · LogQL allows a query to be wrapped with functions to count and aggregate entries per stream. Preserve the instance and job label dimensions: sum by(job, instance) (node_filesystem_size_bytes) Jun 28, 2021 · It means that the over time part, i. These are called metric queries. If a series contains a mix of float samples and histogram samples within the range, the corresponding result is removed entirely from the output vector. avg_over_time() and sum_over_time() act on histogram samples in a way that corresponds to the respective aggregation operators. I am trying to sum up a counter metric over time and grouped by the label applied. Loki supports two types of range vector aggregations: log range aggregations and unwrapped range aggregations. E. Metric queries can be used to calculate things such as the rate of error messages, or the top N log sources with the most amount of logs over the last 3 hours. . , the duration of the aggregation period, comes from the range vector definition itself. For example, min_over_time (foo) or round (foo) leaves foo metric name in the result. MetricsQL keeps metric names after applying functions, which don’t change the meaning of the original time series. sluun pza qtwig hfhh aitrq ppuy eubzpn uijh fwkwtn rtzn
