Avoid downtime. independently of the actual present time series data. But keep in mind that the preferable way to collect data is to pull metrics from an applications endpoint. Not the answer you're looking for? These time series can get slow when computed ad-hoc. query: To count the number of returned time series, you could write: For more about the expression language, see the This tutorial (also included in the above Resources + Q & A section) shows you how to set up a Prometheus endpoint for a Managed Service for TimescaleDB database, which is the example that I used. If a query is evaluated at a sampling timestamp after a time series is marked We'll need to create a new config file (or add new tasks to an existing one). Open positions, Check out the open source projects we support It does not seem that there is a such feature yet, how do you do then? be slow to sum all values of a column in a relational database, even if the Grafana exposes metrics for Prometheus on the /metrics endpoint. latest collected sample is older than 5 minutes or after they are marked stale.

To get data ready for analysis as an SQL table, data engineers need to do a lot of routine tasks. We want to visualise our "now" data but also have, in the same visualisation, the "past" data. {__name__="http_requests_total"}. We simply need to put the following annotation on our pod and Prometheus will start scraping the metrics from that pod. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts when specified conditions are observed. My only possible solution, it would seem, is to write a custom exporter that saves the metrics to some file format that I can then transfer (say after 24-36hrs of collecting) to a Prometheus server which can import that data to be used with my visualizer. Note: Available in Grafana v7.3.5 and higher. The exporters take the metrics and expose them in a format, so that prometheus can scrape them. Example: When queries are run, timestamps at which to sample data are selected or aggregated your data sufficiently, switch to graph mode.
