How to collect native PostgreSQL metrics from RDS The next part of this series will explore how you can set up Datadog to automatically collect, visualize, and alert on RDS PostgreSQL data alongside metrics from more thanĦ00 technologies. If you use a monitoring tool that integrates with the CloudWatch API as well as the other technologies in your stack, you will be able to gain a comprehensive overview of health and performance across all of your services and applications, as well as their underlying infrastructure. You can also use another monitoring tool to regularly query metrics from CloudWatch, and compare and correlate them with metrics from other parts of your infrastructure, including application-specific metrics from the applications that query your database. Setting up an RDS PostgreSQL monitoring tool that integrates with CloudWatch unit: the units you want the metric to be supplied in if the metric is only available in one unit, specifying this parameter won’t do anythingįor example, here’s how you would query the minimum value of FreeStorageSpace at a 60-second granularity over a period of two minutes (yielding the minimum data point in each one-minute bucket), filtered by the name of our database instance identifier (in this case, my-db-identifier):Ĭonsult the AWS documentation for more specific information about structuring your metric queries.Use extended-statistics if you want to query a percentile value between p0.0 and p100 statistics (or extended-statistics): the type of statistic you want to query ( SampleCount, Average, Sum, Minimum, or Maximum).dimensions: The dimensions used to filter this metric, formatted as Name:x,Value:y.period: the period over which all data points during the designated time window should be aggregated (granularity).start-time and end-time: timestamp (in ISO 8601 UTC format) of the first and last data point you want to query.metric-name: the CloudWatch metric name (e.g., FreeStorageSpace).namespace: For RDS, this will be AWS/RDS.You’ll need to supply the following parameters: The AWS CLI’s get-metric-statistics command provides data for the specified metric. Before proceeding, you’ll need to install and configure the AWS CLI by following the instructions here. The AWS command line interface (AWS CLI) provides a quick and easy way to query any particular CloudWatch metric from your RDS database instances, scoped to one or more dimensions. To access metrics from your database instances, visit the AWS CloudWatch console, click on “Metrics” in the sidebar, and select “RDS” under “AWS Namespaces.” Using a CloudWatch-compatible monitoring toolĪccessing RDS metrics from the AWS Management Console.How to collect RDS metrics from CloudWatchĪWS enables RDS PostgreSQL users to access CloudWatch metrics from their database instances in a few different ways: In this post, we will show you how to collect metrics from both of these sources, so you can keep a handle on RDS PostgreSQL database health and performance. In order to gain comprehensive insights into PostgreSQL performance, you will need to collect RDS metrics from Amazon CloudWatch, but you will also need to query PostgreSQL metrics directly from each database instance. I have little understanding of RDS or security groups, i just followed internet tutorials, but seemingly couldnt make much sense out of it.If you read Part 1 of this series, you’ve gotten an overview of the types of metrics that can help you track the health and performance of PostgreSQL on RDS. It then throws the same error i get when trying to connect from my computer. This seemingly has to do with the 2nd security group, as when i remove it, i can no longer connect from my ec2 instances either. I can connect to the DB from my ec2 instances, running the same python script as above. Now i tried to make a security group which allows my computer IP to access the DB. My security groups assigned to the RDS database: Is the server running on host ********* and accepting I get the following error: psycopg2.OperationalError: could not connect to server: Operation timed out I am trying to connect to my RDS database from my computer with a python script using psycopg2.Ĭonn = nnect(dbname=DB_NAME, user=DB_USER, password=DB_PASS, host=DB_HOST)
