Thanos). data-producer-1. Stateless, Secretless Multi-cluster Monitoring in Azure Kubernetes Service with Thanos, Prometheus and Azure Managed Grafana. You can now start seeing monitoring and observability data for your cluster. Everything is curated inside ourterraform-kubernetes-addonsrepository. code of conduct because it is harassing, offensive or spammy. You can think of it as production-ready, but still going through a ton of changes. This stack is often comprise of several components: Prometheus: collect metrics. Learn about Moreover, it manages Prometheus' configuration and lifecycle. We can update the list of stores as well (note that I now have only 2 managed regions because I messed up the Tokyo cluster while testing something else): Change the context to admin and run helm update: If you access Thanos Query, you can now see 2 queries, 1 store and no sidecar: Lets use Thanos to find the amount of memory allocated and still in use by each cluster. Thanos query can dispatch a query to: Thanos query is also responsible for deduplicating the metrics if the same Kubernetes DEV Community 2016 - 2023. your storage needs. Swamynathan Arunachalam on LinkedIn: Multi-Cluster Monitoring with Thanos might still loose 2 hours worth of metrics in case of outage (this is problem on top of each other. With Thanos, yes, you still have to install Prometheus on every cluster. terabyte of data on it. Based on KISS principles and the Unix philosophy, Thanos is divided into components for the following specific functions. For this, we are using the Remote Write option in Prometheus. In this article we are going to see the limitation of a Prometheus only monitoring stack and why moving to a Thanos based stack can improve metrics retention and also reduce overall infrastructure cost. public IP address using a LoadBalancer service. corresponding service port. Remember to change the context and file every time: Verify that all the Prometheus pods are running properly in each region: Next, deploy Thanos in all managed regions. On the Settings page, set the URL for the Prometheus server to In Part 1, we looked at some of the reasons we want to use Thanos, a highly available solution with long term storage capabilities for Prometheus. Thanos is a monitoring system that aggregates data from multiple Prometheus deployments. menu item. }}.monitoring.svc.cluster.local:9000, http://prometheus-operator-alertmanager.monitoring.svc.cluster.local:9093, expr: absent(up{prometheus="monitoring/prometheus-operator"}), Step 1: Install the Prometheus Operator on each cluster, Step 2: Install and configure Thanos on your Kubernetes cluster, Step 3: Install Grafana on the same data aggregator cluster, Step 4: Configure Grafana to use Thanos as a data source, Step 5: Test the multi-cluster monitoring system, deploying a Kubernetes cluster on different cloud platforms, MySQL Overview dashboard in the Percona GitHub repository, Secure Kubernetes Services with Ingress, TLS and Lets Encrypt. Linux is a registered trademark of Linus Torvalds. Create a Multi-Cluster Monitoring Dashboard with Thanos - Bitnami This component acts as a store for Thanos Query. Thanos is running alongside Prometheus. Thanos is an Open source, highly available Prometheus from yesterday. On the "Import" page, paste the JSON model into the "Or paste JSON" field. To do so, we are going to install Prometheus with the Thanos sidecar in each region. Click "Load" to load the data and then "Import" to import the dashboard. deploy a monitoring stack on each cluster. Helm charts: This guide walks you through the process of using these charts to create a We also deployed all the. Only one instance of the Prometheus Operator component should be running in a here and helm upgrade -i thanos -n monitoring --create-namespace --values thanos-values.yaml bitnami/thanos . Click the Kubernetes cluster explorer button. One data aggregator cluster which will host Thanos and aggregate the data The next step is to install Grafana, also on the same "data aggregator" cluster as Thanos. This cluster will also host Grafana for data visualization and reporting. Guide. sounds complex, its actually very easy to achieve with the following Bitnami It is common to start with a Prometheus Thanos query tEKS, our all in one solution to deploy Once deployment in each cluster is complete, note the instructions to connect When deploying Kubernetes infrastructure for our customer, it is standard to "thanos-sidecar.${local.default_domain_suffix}:443", nginx.ingress.kubernetes.io/backend-protocol, nginx.ingress.kubernetes.io/auth-tls-verify-client, nginx.ingress.kubernetes.io/auth-tls-secret, recommendation about cross cluster This article was inspired by several sources, most importantly this two articles: Using Azure Kubernetes Service with Grafana and Prometheus and Store Prometheus Metrics with Thanos, Azure Storage and Azure Kubernetes Service on Microsoft Techcommunity blog. hard-to-guess value and the SIDECAR-SERVICE-IP-ADDRESS-X placeholders with the This allow Prometheus to be almost Scroll down to the Configuration instructions and click the blue Agent configuration instructions button. All of these projects may fit specific use cases, but none of them is a silver-bullet. On the "Settings" page, set the URL for the Prometheus server to. application performance and reliability. Learn about deploying a Kubernetes cluster on different cloud platforms. By using object storage (such as S3), which is offered by almost every cloud Discover how to implement multi-cluster monitoring with Prometheus. Lets check their behavior: So this querier pods can query my other cluster, if we check the webUI, we can You will use this IP address in the next step. The reason is because the dashboard is showing the metrics of the last 30 mins and the data have not been stored to object storage. Use the command below to obtain the public IP address of the sidecar service. Confirm that both In this article we are going to see the limitation of a Prometheus only the number of cluster from which you want to get metrics. Youre sort of stuck (by default) having to install Prometheus and Grafana one by one on each cluster, which results in multiple instances of Prometheus and Grafana to access if you want to set up alerts or check your stack. setup with long term storage capabilities". Add the Bitnami charts repository to Helm: Install the Prometheus Operator in the first data producer cluster using the command below: The prometheus.thanos.create parameter creates a Thanos sidecar container, Next, enter your Kubernetes cluster name and click the Continue button. Next, we enable the ruler and the query components: We also enable autoscaling for the stateless query components (the query and the query-frontend; the latter helps aggregating read queries), and we enable simple authentication for the Query frontend service using ingress-nginx annotations: The annotation references the basic-auth secret we created before from the htpasswd credentials. can inspect them using Grafana. Next, on the Choose data source type page, select Prometheus and set the URL for the Prometheus server with the Thanos service. Once deployment in each cluster is complete, note the instructions to connect to each database service. Cluster, some are better than the other depending on the use cases and we cannot on the scrapping here. Wait for the deployment to complete and note the DNS name and port number for the Thanos Querier service in the deployment output, as shown below: Confirm also that each service displays a unique cluster labelset, as configured in Step 1. metric which is in a Prometheus and also inside an object store, Thanos query Browse to the . Use the command below, replacing GRAFANA-PASSWORD with a password for the Grafana application: Wait for the deployment to complete and obtain the public IP address for the Grafana load balancer service: Confirm that you are able to access Grafana by browsing to the load balancer IP address on port 3000 and logging in with the username admin and the configured password. You just need to implements security on and bitnami thanos chart. Privacy Policy and Terms of Use. that we would like to monitor (node, pod metrics etc.) Operator and Kube All rights reserved. production ready EKS clusters on AWS: Our deployment uses the official scraping Prometheuses from Prometheus, this solution works well when you are not Grafana, is a popular monitoring solution for Kubernetes Thanos query is a UI of Thanos its shows multiple clusters and VMs metrics in one place. Kubernetes Prometheus Stack. which can be used by your Thanos deployment to access cluster metrics. As hinted by its name,Thanos Query Frontendacts a frontend for Thanos Query, its goal is to split large query into multiple smaller queries and also to cache the query result (either in memory or in a memcached). You can view metrics from individual master and slave nodes in each cluster by selecting a different host in the "Host" drop down of the dashboard, as shown below: You can now continue adding more applications to your clusters. MariaDB Helm chart in each data producer cluster and display the metrics Without choosing the right pieces, well end up resigning both databases and Kubernetes to niche roles in our infrastructure, as well as the innovative engineers who have invested so much effort in building out all of these pieces and runbooks. On the "Choose data source type" page, select "Prometheus". there You can also reach us every day on the CNCF/Kubernetes Slack channels. We run a query and then we use the externalLabels we set in each cluster: Lets look at Grafana. This article is from Choerodon Pork-toothed Fish Community*Yidaqiang. here. Storing metrics data for long term use requires it to be stored in a way that is optimized for that use. production configuration with the commands below. Cloud Native Glossary the German Version is Live! Multi-Cluster Monitoring with Prometheus, Thanos & Grafana | VMware Tanzu Developer Center Discover how to implement multi-cluster monitoring with Prometheus. How so ? Today we find Thanos a better and cleaner option. Stores are, as described above, an object store where you can save the metrics. How To: Multi-Cluster Monitoring in Amazon EKS November 17, 2020 Prometheus integrated with Thanos provides a standard monitoring solution to capture metrics and discover any bottlenecks in Amazon EKS Clusters and applications running in and outside the cluster with an exporter. stack, contact us at contact@particule.io :). Note here that although Prometheus is deployed in the same cluster as Thanos for simplicity, it sends the metrics to the ingress FQDN, thus it's trivial to extend this setup to multiple, remote clusters and collect their metrics into a single . It can also cache some information on local storage. Thanos sidecar is available out thanos-syd-storage.yaml, thanos-mum-storage.yaml, thanos-tok-storage.yaml. Visit now http://grafana.example.choerodon.io You can view monitoring information for multiple clusters. Once suspended, thenjdevopsguy will not be able to comment or publish posts until their suspension is removed. Highlight your code snippets using [code lang="language name"] shortcode. space and metric retention time. Multi-cluster monitoring - thanos - Programmer Sought Choose the Kubernetes option. For this section, well use an example of Prometheus and Grafana because its relatable for many engineers and its one of the most popular stacks to use for monitoring and observability in Kubernetes. and that we also installed Thanos in the Singapore cluster. We're a place where coders share, stay up-to-date and grow their careers. to each database service. Note: this deployment model is applicable to single cluster multi-namespace deployments as well. Deduplication also works based on Prometheus replicas and shard in the case of a Prometheus HA setup. Openshift-monitoring: This Is the default cluster monitoring, which will always be installed along with the cluster. On the Choose data source type page, select Prometheus. We will use the Bitnami chart to deploy the Thanos components we need. You're sort of stuck (by default) having to install Prometheus and Grafana one by one on each cluster, which results in multiple instances of Prometheus and Grafana to access if you want to set up alerts or check your stack. Remove Prometheus or Grafana and insert whatever other tool you like to use. deploying a Kubernetes cluster on different cloud platforms. The Prometheus/Grafana combination works well for individual clusters, but as Introducing the Thanos Operator Banzai Cloud Thanos storeacts as a gateway to translate query to remote object storage. The configured password. purposes, this guide will deploy a MariaDB replication cluster using Bitnamis kube-thanos repository and also You can read more here: Multi cluster monitoring with Thanos. Kubernetes Multi-Cluster Monitoring using Prometheus and Thanos Thanos is split into several components, each having one goal (as every service should be ). In production environments, it is preferable to deploy an NGINX Ingress Controller to control access from outside the cluster and further limit access using whitelisting and other security-related configuration. Confirm that both sidecar services are running and registered with Thanos, as shown below: From the Grafana dashboard, click the "Add data source" button. Keep in mind the store may be any other Thanos component that serves labels per Prometheus instance - these labels are useful to differentiate However, this approach is highly To integrate Thanos with Prometheus, install the Prometheus Operator on each cluster, then install and configure Thanos in the data aggregator cluster. the Thanos Querier service in the deployment output, as shown below: Follow the instructions shown in the chart output to connect to the Thanos Monitoring multiple OKE clusters with Prometheus, Thanos and - Medium Thanos sidecaris available out of the box withPrometheus OperatorandKube Prometheus Stackand can be deploy easily. Now, of course, the above relates to any monitoring and observability platform. Keep in mind the store may be any other Thanos component that serves metrics. at the end of Step 2 and PORT is the Deploy MariaDB in each cluster with one master and one slave using the You have the kubectl CLI and the Helm v3.x package manager installed and configured to work with your Kubernetes clusters. Thanks for keeping DEV Community safe. Here we can see all the store that have been added to our central querier: Finally we can head to Grafana and see how the default Kubernetes dashboard have been made compatible with multicluster. Only one instance of the Prometheus Operator component should be running in a cluster. Import it as before and use the Thanos data source and access the dashboard. Effectively, this makes the Singapore cluster our command center: We now want to be to monitor the other clusters too. Thanos main components are:. One "data aggregator" cluster which will host Thanos and aggregate the data from the data producers. Prometheus is an awesome tool to monitor a single cluster. solution (and is also implemented by Thanos receiver), we will not discuss the This makes it easy for Once chosen, run the code on your Kubernetes cluster and click the Continue button. Lets dive into the pricing structure a bit. Ensure you get their values for each region. After waiting a few minutes, youll see a screen similar to the one below. Explore cloud native concepts in clear and simple language no technical knowledge required! Nginx. much time. Also in production environnement Prometheus is often run Required fields are marked *. For example you may want to keep your metrics for 2 or 3 year but you do not need so many data points as your metrics from yesterday. There is no better time than the present for a book such as this, which can surely be seen to be some kind of Skaffold Bible. Thanos is running alongside Prometheus. Next, we need cert-manager to automatically provision SSL certificates from Let's Encrypt; we will just need a valid email address for the ClusterIssuer: Last but not least, we will add a DNS record for our ingress Loadbalancer IP, so it will be seamless to get public FQDNs for our endpoints for Thanos receive and Thanos Query. Note that the same annotations are also under the receive section, as we're using the exact same secret for pushing metrics into Thanos (although with a different hostname). The drawback of this solution is that you cannot make calculation based Built on Forem the open source software that powers DEV and other inclusive communities. Set additional data that you want to gather if the defaults dont work for you and click the Continue button. The command above exposes the Thanos sidecar container in each cluster at a public IP address using a LoadBalancer service. communication, Another Thanos query (they can be stacked), Thanos sidecar that upload to observee specific bucket, this CA will be trusted by the observee clusters ingress sidecar, TLS certs are generated for Thanos querier components that will query the provider. You can also optionally create a MariaDB user account for application use by specifying values for the USER-PASSWORD, USER-NAME and DB-NAME placeholders. Controller to control access from outside the cluster and further limit access Monitoring OpenShift Container Platform 4.6 - Red Hat Customer Portal In One of the main feature of Thanos is to allow for unlimited storage. Step 1: Install the Prometheus Operator on each cluster Bitnami's Prometheus Operator chart provides easy monitoring definitions for Kubernetes services and management of Prometheus instances. github This setup allows for autoscaling of receiver and query frontend as horizontal pod autoscalers are deployed and associated with the Thanos components. clusters. but you can use any Kubernetes provider. Replace the KEY placeholder with a As with all enterprise tools, there is a cost associated. Multi-Cluster Monitoring with Prometheus, Thanos & Grafana - VMware
