Prometheus Not Null. Unary operator The only unary operator in PromQL is - (unary
Unary operator The only unary operator in PromQL is - (unary minus). This is not considered an efficient way of ingesting samples. Discover methods to set nulls as zero, improve data visualization, Using time series graph, I'm plotting a Prometheus Counter source (that has one label) as a time series (by label), and need to fill all null/missing values as zeros. Luckily, there's a nice way of defaulting to 0 instead of null! In order to do that, you can use OR on() vector(0) after the possibly null-ish part of the query. Learn how to handle null values in Prometheus time series data. What's the best way to do this? ORing with My data has tons of null values where no metrics were sent. Explanation: Prometheus uses label matching in expressions. Is there any possibility to do that with prometheus query? This query is not only verbose and hard to write, it might also run into an “identity crisis”: If any of the data labels of target_info changes, Prometheus sees that as a change of series (as up{client=“clientC”, job=“admin”} up{client=“clientD”, job=“admin”} These metrics are from different jobs. By default, prometheus-net will create an exemplar with the trace_id and span_id labels based on the current distributed tracing context . I want to fill in the gaps in this metric with a default value (say 0). As you know Prometheus hides missing values.

Because of this, when I create a table, it’s full of meaningless null Note: This is not an exhaustive list of common Prometheus issues, but rather a selection of examples to demonstrate common pitfalls.
