count(app_version_updated) by (version) Now, the metrics for the EKS add-ons have the priority_class label with values of system-cluster-critical or system-node-critical whereas the prometheus pod metrics do not contain this label at all… . Use the rate() function to specify the time window for the quantile calculation. prometheus. The KSM collects all the metrics from all the pods across all the namespaces in the cluster. Prometheus endpoint of all available metrics… (Samples without such a label are silently ignored.) Prometheus monitors Pod status via kube_pod_status_phase metric. It has a phase label and if the Pod is in that given phase, the call returns a value of 1, otherwise it returns 0. Sometimes it is needed to remove certain labels before storing metrics in Prometheus or VictoriaMetrics. You can extract a sample’s metric name using the __name__ meta-label. After scraping these endpoints, Prometheus applies the metric_relabel_configs section, which drops all metrics whose metric name matches the specified regex. This means that all our labels are always listed but the query returns a different result depending on whether that label is the actual status of the pod. 4. There are two fields that factor into discovery: seriesQuery and seriesFilters. When pods are deployed, their deployment has certain pod-related labels as shown below. Here the count would be 3 for a = "1", "2", "3". Our Prometheus instance stores some interesting metrics, where the relevant information saved as labels and not as metric value: cadvisor_version… Hi guys, I’ve already spent a lot of time , but still have no solution. metric_a and count_values without() ("some_label", metric_b) The count_values function is going to essentially add a some_label label to your metric_b, equal to metric_b's value. To do that, let’s create a prometheus.yml file with the following content. Each sample must have a label le where the label value denotes the inclusive upper bound of the bucket. What I ultimately want is a list of all available metrics. .). Discovery. At this time, we’re using Prometheus with a default configuration. But we need to tell Prometheus to pull metrics from the /metrics endpoint from the Go application. They have two important labels: APP and TEAM: The actual value is going to be 1, but you're not interested in that, just in constructing the right labelset to filter your metric_a by. Kind of like . This can be done with action: labeldrop. Prometheus simply scrapes the metrics from KSM - this way Prometheus doesn't need to scrape the individual pods. Looking at the metrics, I can see that some of them have dynamic names, most probably delivered by dropwizard metrics. I want to count number of unique label values. seriesQuery specifies Prometheus series query (as passed to the /api/v1/series endpoint in Prometheus) to use to find some set of Prometheus series. (Make sure to replace 192.168.1.61 with your application IP—don’t use localhost if using Docker.) The histogram metric type automatically provides time series with the _bucket suffix and the appropriate labels. For example, the query. share | improve this question ... How to get a pod's labels in Prometheus when pulling the metrics from Kube State Metrics. I have also tried to use wildcard in the metric name, prometheus is complaining about that. 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. I want to select all metrics that don't have label "container". The name of the label to drop must be specified as a regular expression in regex. Is there any possibility to do that with prometheus query? Okay you go into Prometheus and you query a single metric in my case kube_node_info. 1. Configure Prometheus. select count (distinct a) from hello_info For example if my metric 'hello_info' has labels a and b. I want to count number of unique a's. Discovery governs the process of finding the metrics that you want to expose in the custom metrics API. In this case Prometheus would drop a metric like container_network_tcp_usage_total(.
