To uninstall the collector for your Prometheus agent, simply remove the following in your Prometheus configuration YAML file. To uninstall the Node Exporter app from your Observe workspace, follow the instructions located at Apps page.ĭelete the associated Observe token as well. Uninstalling Node Exporter ¶ Uninstalling the Node Exporter App ¶ Name Format - The default value of prometheus/%s places your Node Exporter resources within the prometheus folder, but you may want to place them in a different folder. But your node exporter job(s) differ, you can overwrite this list with the values appropriate for your environment. Jobs - By default, the installation includes both “node” and “integrations/node_exporter”, because Prometheus and Grafana set their node exporter job values by default. The default configuration settings of the app may be sufficient for your team needs, but you should consider overwriting the defaults for the following options:ĭatastream - select the datastream receiving your Node Exporter metrics Install the Node Exporter App for Observe using the App section under Workspace Setting. If you have already created a data connection in the app, you do not need to perform these steps again. This setup follows the same procedure as creating a data connection in the Node Exporter app. Whether you use the Prometheus or the Grafana agent, configure your remote-write to point to your Observe instance with the following configurations: prometheus.yml ¶ The –collector.systemd and –collector.processes collectors are optional, but recommended, since a few graphs also use their metrics. The Observe app uses many of the metrics generated by the Node Exporter default collector configurations. Use either the Prometheus Node Exporter or the Grafana Node Exporter integration to generate your Node Exporter metrics. View an aggregation of this data across many nodes, or more detailed views when you filter to an individual node.įigure 2 - Node Exporter System Overview dashboard Setup ¶ Configuring Node Exporter ¶ The System Overview dashboard visualizes several groups of system-related metrics, including the following types:Ĭount of system processes by state, thread-count, etc. When you filter to a specific node, the graphs provide more detailed information specific to the selected node.įigure 1 - Node Exporter CPU / Mem / Net / Disk Overview dashboard System Overview ¶ While you can select more than one node, each graph provides an aggregation of the nodes’ data. The CPU / Mem / Net / Disk Overview dashboard displays a high-level summary of the fundamental resources of your nodes, followed by two tiers of more detailed information. From this resource, you can filter to any number of node instances and use the following dashboards to get insight into their health and status. This dataset models the nodes that are running the Node exporter in your environment, whether in a Kubernetes cluster or as a service on a standalone host. To see the health and performance of your nodes, after installing the app, go to the Instance dataset in Observe. What is the network performance for my nodes? Which nodes have usage spikes in the CPU?Īre some of my nodes running out of memory or disk space? With this app, you can answer questions such as the following: Use the Observe Node Exporter App to gain insight into your node health through those metrics. The Prometheus Node Exporter exposes a wide variety of hardware and kernel-related metrics that give visibility into important health and performance metrics related to CPU, Memory, Network, Disk Space, System Load, and more.
