Thanos will work in cloud native environments as well as more traditional ones. pushing metrics As an additional step, install and configure Grafana to use Thanos as a data source and start deploying applications into your data producer clusters and collating the metrics in Thanos and Grafana. Please note that at this time Thanos is a CNCF Incubator project. Remember when we said the querier can stack on top of each other. of the box with Prometheus A multi-cluster Prometheus environment is created when an instance of Prometheus is installed (as required) in each of the many Kubernetes clusters under operational management. 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. Yes, with the Prometheus/Grafana combination, you can monitor multiple Kubernetes clusters and multiple providers. Here is what you should see: At this point, you can start deploying applications into your "data producer" clusters and collating the metrics in Thanos and Grafana. Now that youve looked at the pricing model, lets dive into the installation. Thanos store acts as a gateway to cluster. Posted by KoshNaranek on Fri, 20 Mar 2020 01:16:48 -0700, Introduction to Prometheus-operator and Configuration Resolution, http://choerodon.io/zh/docs/installation-configuration/steps/, http://choerodon.io/zh/docs/installation-configuration/update/0.20-to-0.21/. 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. 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. Click Save & Test to save and test the configuration. 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 It allows SRE teams and developers to capture metrics and telemetry data for applications running in a cluster, allowing deeper insights into application performance and reliability. After you select 1 cluster, you should see the values in the various panels change: Now, we can monitor the performance of various resources in OCI across many regions, VCNs and even tenancies simultaneously. Youll now see that the monitoring and observability information is being consumed by Grafana. This component act as a store for Thanos Query. deploying a Kubernetes cluster on different cloud platforms. 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 But if you want to query multiple clusters, you need the help of other tools. Its just with a different tool. The directory structure is the following inside thethanosdemo folder: This allow for DRY(Dont Repeat Yourself) infrastructure and to easily scale the number of AWS accounts, regions and clusters. Querier receives HTTP's PROMQL query, the component is responsible for data query aggregation, the query process is as follows: In short, it is to collect the data required to evaluate the query from the base StoreApi, evaluate the query and return the result. MariaDB Helm chart in each data producer cluster and display the metrics For even greater scalability and metrics isolation, Thanos can be deployed multiple times (each associated with different storage accounts as needed) each with a different ingress to separate at the source the metrics (thus appearing as separate sources in Grafana, which can then be displayed in the same dashboard, selecting the appropriate source for each graph and query). object store for metrics. The observer cluster is our primary cluster from which we are going to query the other clusters: A CA is generated for the observer cluster: Observee clusters are Kubernetes clusters with minimal Prometheus/Thanos installation that are going to be queried by the Observer cluster. Welcome to the Choerodon Pork*Tooth Community to create an open ecological platform for enterprise digital services. It gives you a declarative way to manage Kubernetes resources and confirms that the current state is the desired state. 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. Always remember to apply the principles of least privileges!). Thanos is a powerful tool that allows you to build highly available, multi-cluster monitoring systems. Browse to the Thanos Query is the main component AlertManager: send alerts to various provider based on metrics query. 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. Thanos is split into several components, each having one goal (as every service Theres a big chance that throughout your Kubernetes journey, youll have to manage multiple Kubernetes clusters. 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, while the prometheus.thanos.service.type parameter makes the sidecar service available at a public load balancer IP address. Stateless, Secretless Multi-cluster Monitoring in Azure Kubernetes Service with Thanos, Prometheus and Azure Managed Grafana. It is common to start with a Prometheus only setup and to upgrade to a Thanos one. 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. and can be deploy easily. new dashboard should appear in Grafana, as shown below: Connect to the MariaDB service in the first data producer cluster and There are a lot of enterprise options that are available, but in this section, youll dive into New Relic. In this setup each cluster has its own Grafana with its own set of dashboards configured correctly, you should see a success message like the one below. Thanos is a really complex system with a lot of moving parts, we did not deep dive on the specific custom configuration involved here as it would take too much time. Each variation has its advantages and disadvantages with possible regulatory implications (if you need to conform to these) necessitating infrastructural, architectural and financial tradeoffs. Thanos is an Open source, highly available Prometheus You can now start seeing monitoring and observability data for your cluster. Repeat the steps shown above for the second "data producer" cluster. data for applications running in a cluster, allowing deeper insights into Querier is the key to multi-cluster monitoring and global views of ThanOS. Choerodon Porcine Tooth* As an agile full-link technology platform for open-source multi-cloud applications, it is based on open-source technologies such as Kubernetes, Istio, knative, Gitlab, Spring Cloud to achieve the integration of local and cloud environments, and to achieve the consistency of enterprise multi-cloud/hybrid Cloud Application environments.Platforms help organize teams to complete software life cycle management by providing capabilities such as lean agility, continuous delivery, container environments, micro services, DevOps, and so on, to deliver more stable software faster and more frequently. You have the kubectl CLI and the Helm v3.x package manager installed and configured to work with your Kubernetes clusters. For each of the managed clusters, repeat the following: Next, we will deploy Prometheus with the sidecar in each region. It is also a part of the CNCF incubating Once complete, wait a minute or two, refresh your page, and click on the Kubernetes Monitoring option again. This stack is often comprise of several components: The simplify architecture is the following: This architecture has some caveats and does not scale out well when increasing the number of cluster from which you want to get metrics. It not only installs Prometheus and Grafana, but best practice dashboards and other configurations like Alert Manager. If you want to store data for a long time and running on a Cloud Provider, block storage can be expensive if you store terabyte of data on it. the number of cluster from which you want to get metrics. Multi-Cluster Monitoring with Thanos By Kevin Lefevre at February 23, 2021 Introduction 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. Grafana, is a popular monitoring solution for Kubernetes You can read about the pros and cons of cluster or tenant (for example when building a Prometheus as a service Thanos is a monitoring system that aggregates data from multiple Prometheus deployments. solution (and is also implemented by Thanos receiver), we will not discuss the while the prometheus.thanos.service.type parameter makes the sidecar service On the Settings page, set the URL for the Prometheus server to Cloud Native Glossary the German Version is Live! You'll need a strong password stored into a file called pass locally: We now have the secrets in place for the ingresses and for deploying Prometheus. thanos-syd-storage.yaml, thanos-mum-storage.yaml, thanos-tok-storage.yaml. As with all enterprise tools, there is a cost associated. Basically this is the component that allows you to query an object store for metrics. Save my name, email, and website in this browser for the next time I comment. Thanos deployment that aggregates data from Prometheus Operators in multiple In this article, we will look at how we can monitor multiple clusters. 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. Rinse and repeat for any other Kubernetes clusters you have. Everything is curated inside ourterraform-kubernetes-addonsrepository. Write Minio parameter configuration file minio.yaml: Log in to minio to create a thanos bucket. metric which is in a Prometheus and also inside an object store, Thanos query If you want to dive deeper into Thanos you can check their officialkube-thanosrepository and also theirrecommendation about cross cluster communication, And of course, we are happy to help you setup your cloud native monitoring stack, contact us atcontact@particule.io. On the Choose data source type page, select Prometheus. How so ? One of the main feature of Thanos is to allow for unlimited storage. available at a public load balancer IP address. Prometheus is a very flexible monitoring solution wherein each Prometheus server is able to act as a target for another Prometheus server in a highly-available, secure way. Thanos is a monitoring system that aggregates data from If running on premises, object storage can be offered with solution We also deployed all the components of Thanos in our admin Verrazzano cluster. To do so, we are going to install Prometheus with the Thanos sidecar in each region. different stores or data sources in Thanos. You will use this IP address in the next step. granularity on your metrics over time. Let's look at how we can set it up for multi-cluster monitoring in AWS. Thanos query special firewall or routing configuration. Thanos compactor is a singleton How does this work? scraping a lot of metrics. 1.1. On the "Settings" page, set the URL for the Prometheus server to. As such, monitoring, feature-rich metrics, alerting tools, and data visualization frameworks are a key element of . them as Datasource in a single Grafana. Thanos can be deployed multiple times (each associated with different storage accounts as needed) each with a different ingress to separate at the source the metrics . Only one instance of the Prometheus Operator component should be running in a terabyte of data on it. Lets check what is running on our clusters. Thanos Queryis the main component of Thanos, it is the central point where you send promQL query to. to each database service. been made compatible with multicluster. It allows SRE teams and developers to capture metrics and telemetry Querier Web interface and navigate to the Stores tab. Overview chart in Grafana, as shown below: You can view metrics from individual master and slave nodes in each cluster by Cluster A, Cluster B etc.) This allow Prometheus to bealmoststateless. It also includes an optional Thanos sidecar container, Nov 29, 2021 -- 1 In a previous article, we deployed multiple OKE clusters for Verrazzano in different OCI regions. It allows for ephemeral clusters to still have updated metrics without the 2-hours local storage of metrics in the classic deployment of Thanos sidecar to Prometheus. This stack is often comprise of several components: Prometheus: collect metrics. replicas and shard in the case of a Prometheus HA setup. We will use the Bitnami chart to deploy the Thanos components we need. At this point, you can start deploying applications into your data producer Content used for this demo is available Then it dispatches query to all of it stores. In the following sections, youll learn about three tools/platforms that you can use which make centralizing your configurations a bit more straightforward. series comparisons across and within clusters and high availability is essential Content used for this demo is availablehereandthereand are submit to their respective licenses. There are multiple way to deploy these components into multiple Kubernetes Then it dispatches query to all of it If thenjdevopsguy is not suspended, they can still re-publish their posts from their dashboard. You can also learn about the latest developments, product characteristics, and community contributions of pork toothfish through the following community*. Thanos is running alongside Prometheus (with a sidecar) and export Prometheus metrics every 2h to an object storage. On theobserverwe have: Our TLS querier are supposed to be able to query the observee cluster for metrics. From the Grafana dashboard, click the "Import -> Dashboard" menu item. Thanos is based on Prometheus.Prometheus is more or less used when we use Thanos in different ways, but Prometheus is always the basis for the early warning function to target collection and use local data. Choose the Kubernetes option. Downsampling is the action of loosing Next, on the Choose data source type page, select Prometheus and set the URL for the Prometheus server with the Thanos service. For a list of trademarks of The Linux Foundation, please see our Trademark Usage page. exposes a Prometheus compatible endpoints. We will use the same credentials (but feel free to generate a different one) to push metrics from Prometheus to Thanos using remote-write via the ingress controller. Discover how to implement multi-cluster monitoring with Prometheus. translate query to remote object storage. perform some actions, such as creating a database, adding records to a table Highlight your code snippets using [code lang="language name"] shortcode. Accessibility Statement Sidecar: Connect Prometheus and expose Prometheus to Querier/Query for real-time query, and upload Prometheus data to cloud storage for long-term storage; Querier/Query: Implements the Prometheus API and aggregates data from underlying components such as Sidecar, or Store Gateway, which stores gateways; Store Gateway: Expose data content from cloud storage; Compactor: Compress and downsample data from cloud storage; Receiver: Get data from Prometheus'remote-write WAL (Prometheus remote pre-write log) and expose it or upload it to cloud storage. However, there are several difficulties that naturally arise when creating a production-ready version of such a system: be exhaustive here. By submitting this form, you acknowledge that your information is subject to The Linux Foundation's Privacy Policy. Prometheus is still keeping 2 hours worth of metrics in memory so you might still loose 2 hours worth of metrics in case of outage (this is problem which should be handle by your Prometheus setup, with HA/Sharding, and not by Thanos). When deploying Kubernetes infrastructure for our customer, it is standard to deploy a monitoring stack on each cluster. specifying values for the USER-PASSWORD, USER-NAME and DB-NAME placeholders. The configuration file thanos-storage-minio.yaml. Kubernetes Prometheus Stack. monitoring, a single pane of glass with centralized real-time monitoring, time Privacy Policy and Terms of Use. The relationship between components is illustrated in the following figure: The easiest way to deploy Prometheus in a K8S cluster is to install it using helm prometheus-operator .Read more about Prometheus-operator Introduction to Prometheus-operator and Configuration Resolution .Prometheus-Operator provides highly available support, the injection of Thanos Sidecar components, as well as monitoring servers and Kubernetes infrastructure components, to monitor pre-built alerts required by applications.
