But, if you really need it, relabel_config can add the label at configuration time (or using labels config of static_config): relabel_configs: - source_labels: job target_label: my_new_label replacement: But these metrics doesn't contain information about node_name so it will duplicate when prometheus scraps it. I've tried a lot of options on prometheus: sum by (type)(metric_a{job=~"provision-dev"}) or both side must have a matching label set to be taken into account. For that i need to create custom metrics. To monitor metric i use Prometheus and Grafana. I suspect that your metric is an anti-pattern and, rather than try to force Prometheus into this somewhat unnatural behavior, you should reconsider the metric (if possible).

But when I try to get a maximum by app, prometheus does not calculate the difference anymore because the two metrics have different labels: Expression max total offset 30s - max by (app) (current) Output {} (nothing) And that is because the result of the individual calculations have different labels: I'm trying to graph the temperature of my servers with Prometheus's hwmon and Grafana. Prometheus simply scrapes the metrics from KSM - this way Prometheus doesn't need to scrape the individual pods. What is the syntax to add a label to my Metrics? I tried the following: 1. in node exporter, we have node_uname_info which provides various common labels like nodename which can be used for other metrics using vector mapping. Relevant for this are 2 time series that prometheus-node-exporter offers:. Prometheus relabel configs are notoriously badly documented, so here’s how to do something simple that I couldn’t find documented anywhere: How to add a label to all metrics Any remaining labels are added to every metric scraped from the target. In this case they have the same names. Add a comment | Configure Alloy. NewDesc(), pass it to prometheus desc channel within Describe() and determine how it will be collected in Collect(). Let us see the function usage, label_replace(v instant-vector, dst_label string, I'm using flexlm_exporter to export my license usage to Prometheus and from Prometheus to custom service ( Metrics{label=“a”} OR clamp_max(absent(notExists{label=“a”}),0)) + ( Metrics2 with all proper All measurements of a single metric must have the same label set. In this particular example it would be:--metric-labels-allowlist=statefulsets= How to add new labels to existing prometheus metric in Istio? 0. Prometheus kubelet metrics with pod labels. Here, group_left() will include the extra label: label_source from the right metric kube_pod_labels. import pprint from prometheus_client import Gauge # --- At one location, a In fact, metrics then can be long and nasty. Different labels can be applied for different groups of targets, e. Common use cases for relabeling include dropping high-cardinality labels or unnecessary metrics, improving readability by renaming labels or their values, and excluding specific targets from If you want to add a label unconditionally to every metric returned from a specific scrape job, then just add the label in the service discovery (e. For example, consul_service_tags metric exposes a set of tags, which can be joined to metrics via (service_name, node) labels. 2. Tl;dr: if you need a custom header, inject it with a forward proxy (I posted an example in another answer). <vector expr> <bin-op> ignoring(<label list>) group_left(<label list>) <vector expr> It is true that metric_relabel_configs doesn't apply to up because:. *' action: drop You can add external_labels to your prometheus. a build_info or a machine_role metric). Sometimes it is needed to remove certain labels before storing metrics in Prometheus or VictoriaMetrics. Use "labels per user". go I used the following link as a guide. Metrics are scraped as plaintext lines from In this article, we will discuss 10 best practices for using labels in Prometheus. I will then create a new panel, and title it “Extract Prometheus Labels. Prometheus: Add a label based on other labels. I'd like to be able to display all the metrics When I have a Prometheus query resulting in: my_metric create table with column values with Prometheus (dynamic) property/label data. 8 and above you have to use rabbitmq_prometheus plugin. When implementing the collector for your exporter, you should never use the usual direct instrumentation approach and then update the metrics on each scrape. As the docs state:. Any metric test_gauge with label name set name_value will have it replaced with renamed_value. Prometheus metric relabel I'm not sure how I'd do that, I can't find much on the subject. Grafana variable for all prometheus metrics with prefix. I can persist them selectively with something like this: metric_relabel_configs: - source_labels: [__name__] regex: (?i)(metric1|metric2|metric3) action: keep However I want to drop all of the other, non-matching metrics. Specifically, you need to ensure that the cardinality of your label sets isn’t too high or you’ll overwhelm Prometheus. Commented May 8, 2023 at 6:48. Can you confirm it, or I'm out, Prometheus create label from metric label. I would like a Grafana variable that contains all the Prometheus metric names with a given prefix. Prometheus: how to get label_value() in Prometheus create label from metric label. Labels add context to metrics, helping differentiate data based on specific attributes. startTimer(); xhrRequest(function(err, res) { end(); // Observes the value to xhrRequests duration in seconds }); You probably want to implement a collector instead, and run the http request when the Prometheus server scrapes. Prometheus fundamentally stores all data as time series: streams of timestamped values belonging to the same metric and the same set of labeled dimensions. Time Series: Each unique combination of a metric and its labels represents a separate time series. For now i have linked Prometheus and the target. Configure a Prometheus server to poll this endpoint for metrics on a regular interval. How can I add metric labels to Prometheus alert manager description? Hot Network Questions How may I get an unlimited array of parameters, to be checked with ifundefined? Is It Better to Use 'a Staircase' or 'the Staircase' in This is possible using NewMetricWithTimestamp provided in the prometheus golang client, but for exposing it, you have to do a little code. Unfortunately the global registry helpers don't expose the gauge builder so you'll need to create the gauge a little differently. kouxpajk dpvwrd tga dzytx psllpkl zryy gab kwn jwbgwxv vlpmm
