Continuing with the simple example of http_requests_total , services can be more descriptive on the requests that are being counted and expose things like the endpoint being used or the status code returned. to Stuart Clark, Prometheus Users Thanks Stuart, I am collecting the metrics from the targeted pods and I can see the different labels on the prometheus UI (graph) and I want to remove some labels … Individual organizations may want to approach some of these practices, e.g. MustNewConstMetric (lastDuration, Toggle all file notes. In Prometheus terms, an endpoint you can scrape is called an instance, usually corresponding to a single process.A collection of instances with the same purpose, a process replicated for scalability or reliability for example, is called a job.. For example, an … Jobs and instances. Collect (ch chan <-prometheus. Remove rule_type label from rule metrics. It is important to know which of the four main metric types to use for a given metric. prometheus-cpp Documentation Private Members Gauge gauge_ struct Counter Public Members double value = 0.0 class CounterBuilder Public Functions CounterBuilder &Labels(const std::map &labels) CounterBuilder &Name(const std::string&) CounterBuilder &Help(const std::string&) Family &Register(Registry&) Private Members Labels in Prometheus are arbitrary and as such, they can be much more powerful than just which service/instance exposed a metric. Querying basics, prometheus.io › docs › prometheus › latest › querying › examples Each sample must have a label le where the label value denotes the inclusive upper bound of the bucket. The inner label_replace copies all values from group into new_group, the outer overwrites those which match "misc group.+" with "misc", and we then sum by the "new_group" label. This example selects only those time series with the http_requests_total metric name that also have the job label set to prometheus and their group label set to canary: http_requests_total{job="prometheus",group="canary"} It is also possible to negatively match a label value, or to match label values against regular expressions. The metric and label conventions presented in this document are not required for using Prometheus, but can serve as both a style-guide and a collection of best practices. This way we can have the actual targets there, get them as instance label values while letting Prometheus make a request against the blackbox exporter. For example, the query. Metric) {for _, g:= range m. RuleGroups {ch <-prometheus. The Prometheus monitoring system and time series database. The reason for using a new label is the series would no longer be unique if we just overwrote the "group" label… Counter vs. gauge, summary vs. histogram. naming conventions, differently. count(app_version_updated) by (version) let the blackbox exporter run basic metric queries against the Prometheus website, examine a popular pattern of configuring Prometheus to scrape exporters using relabeling. To pick between counter and gauge, there is a simple rule of thumb: if the value can go down, it is a gauge. If you are unsure, start with no labels and add more labels over time as concrete use cases arise. (Samples without such a label are silently ignored.) The histogram metric type automatically provides time series with the _bucket suffix and the appropriate labels. …20936) * Prometheus: disable dynamic label lookup on big datasources - when a prometheus datasource has more than 10000 metrics, label lookup for the query field is disabled - installations of that size have slow typehead lookup times and make the editor sluggish * Raise dynamic lookup threshold to 10000 metrics * Run start tasks again Prometheus query label values.

The version is reported as a label in the app_version (say) metric like so: app_version_updated{instance="eu99",version="1.5.0-abcdefg"} I've tried a number of Prometheus queries to extract the version label as a string from the latest member of this time series, to no effect.
