20.05.2019 · Prometheus provides a query language called PromQLto do this. To query our Counter, we can just enter its name into the expression input field and execute the query. We get one result with the value 0 (ignore the attributes in the curly brackets for the moment, we will get to this later). Figure 1 – query result for our counter metric
Counters can only go up (and be reset), if your use case can go down you should use a Gauge instead. Use the rate () function in Prometheus to calculate the rate of increase of a Counter. By convention, the names of Counters are suffixed by _total . An example Counter:
26.12.2016 · The Prometheus gauge is essentially the same simple idea as gauges in other monitoring systems. Gauges can go up and down over time, and scrapes take a snapshot of the current value. There's no potential for messing around …
Counter vs. gauge, summary vs. histogram. It is important to know which of the four main metric types to use for a given metric. To pick between counter and gauge, there is a simple rule of thumb: if the value can go down, it is a gauge. Counters can only go up (and reset, such as when a process restarts).
04.11.2019 · 19 When deciding between Counter and Gauge, Prometheus documentation states that To pick between counter and gauge, there is a simple rule of thumb: if the value can go down, it is a gauge. Counters can only go up (and reset, such as when a process restarts).
Gauge. Gauge is a single-value visualization that can repeat a gauge for every series, column or row. ... using Grafana 8 and the Grafana 8 user interface while showing how to set up monitoring for a web service that uses Prometheus and Loki to store metrics and logs. :
05.02.2021 · A Prometheus gauge is a specific type of metric used for measurements. That means your service always returns to Prometheus the current value of whatever it is you’re measuring. Prometheus is regularly scraping your service for metrics though, and when your gauge’s current value is returned Prometheus stores this against the current time.
