![]() The number of open TCP connections, grouped by node. The same as the Network graph, but values are not grouped by service node. The number of inbound and outbound bytes per second for a node. This gives you an opportunity to respond quickly when the database starts to slow down from too many read and write operations. The percentage of CPU time spent waiting for the disk to become available for read and write operationsĪiven suggest to create an alert that is triggered when iowait goes beyond a certain threshold for an extended time. The amount of disk space that is in use on the service’s data disk. The number of bytes read and written per second on each of the nodes. The database will stop working correctly if it runs out of disk space. The current amount of remaining disk space.Īiven suggest to actively monitor this value and associate it with an alert. Processes that are mostly idle are not included. The number of processes that are actively doing something. The number of switches from one process or thread to another. The amount of memory not allocated by running processes or used for buffer caches. The amount of memory not allocated by running processes. The Load average figure is higher than the number of CPUs on the nodes, the service might be under-provisioned. The number of processes that would want to run. ![]() System, user, iowait, and interrupt request (IRQ) CPU usage.Ī high iowait is an indication that the system is writing or reading too much data to or from disk. The default dashboard can be used as a template to make the process easier. ![]() New dashboards can be created to show any metrics or use any filtering criteria. Some metrics are gathered but not shown in the default dashboard, you can access all available metrics by creating new dashboards. The PostgreSQL dashboards show all tables and indexes for all logical databases since Aiven cannot determine tables or indexes relevance. General info about default dashboards #Ī few key points about the default dashboards pre-created by Aiven in Grafana: This article describes the default dashboard created in Grafana for any PostgreSQL instance. For more information on enabling the integration, see Monitor PostgreSQL® metrics with Grafana®. The metrics/dashboard integration in the Aiven console enables you to push PostgreSQL® metrics to an external endpoint like Datadog or to create an integration and a prebuilt dashboard in Aiven for Grafana®. PostgreSQL® metrics exposed in Grafana® #
