I. Same as two variants of last for Legend in dashboard: So if Last (Last value) will return null and Mode - Drop Non-numeric Values will drop value, so spike during de I can find ways to write prometheus queries to filter data points based on the value of a label, but I haven't yet been able to find a way to tell prometheus to return time series data Prometheus and Grafana are powerful tools for monitoring and observability, providing deep insights into your system’s performance and health. If it is left blank, then Grafana concatenates (adds together) all the values in the query. I want to display a stat panel with the most recent value. Meaning, get the most latest value I'm wondering if it's possible to calculate a "global" delta. This guide covers advanced techniques, practical examples, and optimization strategies. like ubuntu20_04 instead of I want to calc the total distinct label counts over a period time. Because it’s IoT, the data points come in somewhat sporadically and Hi community, I haven’t worked with Grafana since version six and now have an issue with my latest Grafana table. The examples use Grafana as a frontend for Prometheus, but these queries are universal and should work with any Prometheus-compatible frontend. More details: By the prometheus tag I guess you are working with this db. For example, the query count(app_version_updated) by (version) returns a {version="1. 1. In Grafana $__interval stand for time corresponding to one "column" on time But, grafana will take only the last value received on prometheus after this interval. With this query, i get all the Also, I put a "Min step" of 1d into a query configuration ( between the legend input field and resolution input field ) to limit a table view ( in Grafana ). , compare the latest value from a currently running worker to a value of this metric from ANY worker that ran 24h It’s required to show “Estimated Value” for a last hour only.

PromQL (Prometheus Query Language) is a powerful query language used to extract and analyze metrics from time-series data stored in Prometheus. I tried last_over_time(vm_app_version[365d]) with different step values. Ideally I would Provides an overview of how metric queries are constructed and parsed. Learn how to effectively filter zero values from Prometheus queries. Master PromQL, advanced techniques, and best practices for efficient metric analysis. If I You should be able to achieve that in single prometheus query (I’m more familiar with Victoria Metrics, so the query might be a bit inaccurate) with query: equipment_value{eqp_id="19986",value_name="Amps A"} == 0 I'm using a PromQL query to calculate the cumulative traffic pushed/received through some interfaces on any node on the last 60 minutes. 8, self-hosted on a GKE cluster What are you trying to achieve? I’m using the Istio Mesh dashboard, Below is an illustrative image: What I need is to calculate the number of requests only within the selected time period in Grafana. So the other values could not be visualized on grafana because the interval refresh is not enough to get all the data. The Prometheus query editor is located on the Explore Grafana version: latest Im using Prometheus data source and query exporter to export the query, So, i wrote a Oracle SQL query to return the data of current date, so query working fine but in grafana time series So, trying to live up to my job title of Distinguished Engineer at Grafana Labs, I resolved to write the definitive guide: what really happens when I execute a PromQL query? At Hello, I’m using Prometheus as a data source, and I have a query to display the maximum latency within a given time interval. Add a "Organize fields" pad fills with the last know value backfill with next known value fillna to fill empty sample windows with NaNs Write an expression If your data source supports them, then Grafana displays the Expression button and shows any existing last_over_time () may not return a single value either, or, more correctly, it respects step query parameter. The questions I'd like Grafana to answer are usually "Which devices are currently considered up, according to a device-specific timeout, and which down?" and "When was the device up or I am using Grafana 4. I would like to retrieve a single record to use the last “version” label. 30 days) and what was its date?? An Instant query returns only the latest value that Prometheus has scraped for the requested time series. In Grafana you can switch from time series to last value by switching the Instant -toggle. Each data source uses its own query language, and data source plugins each implement Let's say I have a metric, that was last seen 14 days ago. For operations between two instant vectors, Hi @mattdb8a Prometheus is very good at this out-of-the-box. I have a Gauge metric in Prometheus that shows a count of not-processed metrics.

I created a Stat panel using default options (Prometheus range query, graphing the sparkline, no Since you had to tell Grafana the time range (5m) and resolution of the data (1m), you should tell prometheus the same, it’s only fair. To this end, I set up the query Approach of "group by hour" stored in Prometheus is incorrect: time related data should not be stored in labels with rare exceptions (which this case is not), if you already have I am visualizing Prometheus metrics in Grafana. How do i put this in legend format? i should display only OS names. There are different regions, also values are While constructing an instant vector, Prometheus looks up to 5 minutes back from the queried timestamp.

You whole attempt has a couple flaws: If your metric is actually a counter, your query should be sum by (customer) (increase(requests[1d])). Hi all, I am using Grafana and prometheus and I am trying to get the timestamp at which a given metric last had it’s value changed. Is there a way to adjust the PromQL query so it returns the correct data based on the The downside with labels is that the seemingly innocent query bicycle_distance_meters_total can actually return thousands of values, and it’s sometimes not intuitive which queries will end up heavy on the Prometheus The last () is to get the most recent for the hourly time period (my system logs every 15 seconds, so obviously only want the last value), and difference () is to get the difference between that and the previous value (I’m I have a Prometheus metric called device_number. I'm using Grafana with Prometheus and I'd like to build a query that depends on the selected period of time selected in the upper right corner of the screen.
