These adjustments should be an integral part of your applications. At the moment we don’t have access to Prometheus, since it’s running in a cluster. No credit card required. Once this is applied we can view the available namespaces with the command: The next step is to setup the configuration map. We can bring up all the metrics for that job by searching for the label “job” with the value “prometheus”. It should give you a good start however, if you want to do further research. To view prometheus metrics scraped by Azure Monitor and any configuration/scraping errors reported by the agent, review Query Prometheus metrics data and Query config or scraping errors. prometheus.io/port: Scrape the pod on the indicated port instead of the pod’s declared ports (default is a port-free target if none are declared). In this file we can see the apiversion, which is v1 again, the kind which is now ConfigMap, and in the metadata we can see the name, “prometheus-config”, and the namespace “monitoring”, which will place this ConfigMap into the monitoring namespace. The restart is a rolling restart for all omsagent pods, not all restart at the same time. kubernetes, All resources in Kubernetes are launched in a namespace, and if no namespace is specified, then the ‘default’ namespace is used. Prometheus is a popular open source metric monitoring solution and is a part of the Cloud Native Compute Foundation. A Label is required as per the selector rules, above, and will be used by any Services we launch to find the pod to apply to. To verify your agent version, from the Node tab select a node, and in the properties pane note value of the Agent Image Tag property. Creating Scraping Configs for Kubernetes Resources in Prometheus. To configure scraping of Prometheus metrics from an agent's DaemonSet for every individual node in the cluster, configure the following in the ConfigMap: $NODE_IP is a specific Azure Monitor for containers parameter and can be used instead of node IP address. The Template section is the pod template, which is applied to each pod in the set. Prometheus is an open source application monitoring system that offers a simple, text-based metrics format to give you an efficient way to handle a large amount of metrics data. This command is not applicable to Azure Red Hat OpenShift v3.x cluster. For example, monitor_kubernetes_pods_namespaces = ["default1", "default2", "default3"]. Run the command oc edit configmaps container-azm-ms-agentconfig -n openshift-azure-logging to open the file in a text editor. Typically, to use Prometheus, you need to set up and manage a Prometheus server with a store. We're creating all three of these in one file, and you could bundled them in with the deployment as well if you like. Perform the following steps to configure your ConfigMap configuration file for the following clusters: Download the template ConfigMap yaml file and save it as container-azm-ms-agentconfig.yaml. From Live Data (preview). we're going to use an application called Node Exporter to get metrics about the cluster node, and then change the Prometheus configmap to include jobs for the nodes and pods in the cluster. In Spring Boot 2.x, any monitoring endpoint under the context path /actuator and the port do not meet the expectation from Prometheus. People who use kubernetes_sd are probably already familiar with the prometheus.io/scrape annotation that can be set on pod specs, as explained here. We have a namespace to put everything in, we have the configuration, and we have a default service account with a cluster role bound to it. This tutorial takes a short excursion into IBM Cloud Monitoring with Sysdig. That’s how node-exporter accesses metric values. If you have already deployed a ConfigMap to your cluster and you want to update it with a newer configuration, you can edit the ConfigMap file you've previously used, and then apply using the same commands as before. You can find versions of the files here with space for your own details: https://github.com/shevyf/prom_on_k8s_howto. There’s no number of replicas however, since that’s fixed by the DaemonSet, but there is a PodTemplate as before, including metadata with annotations, and the spec for the container. Collect the information you need: Right click and select Display key. Scrape system components: API server, kubelet and cAdvisor. ConfigMaps is a global list and there can be only one ConfigMap applied to the agent. For example, k8s services such as kube-dns and kube-state-metrics, and pod annotations specific to an application. In OpenShift, this can be advantageously inferred from a template parameter. We won’t use this immediately, but we can see that we’ve annotated a port as 9090, which we can also view farther down. To configure scraping of Prometheus metrics by specifying a pod annotation, perform the following steps: Specify the following configuration for pod annotations: If you want to restrict monitoring to specific namespaces for pods that have annotations, for example only include pods dedicated for production workloads, set the monitor_kubernetes_pod to true in ConfigMap, and add the namespace filter monitor_kubernetes_pods_namespaces specifying the namespaces to scrape from. To identify the ingestion volume of each metrics size in GB per day to understand if it is high, the following query is provided. Prometheus will periodically check the REST … This is a very simple command to run manually, but we’ll stick with using the files instead for speed, accuracy, and accurate reproduction later. The tags allow multiple views per dimension on the same metric. The collection interval default is one minute (60 seconds). With minimal effort, you can achieve more transparency and insight into your own application. The following code listing displays the counter integration for a Spring Boot REST endpoint. They are converted into labels which can be used to set values for a job before it runs, for example an alternative port to use or a value to filter metrics by.
