AWS RDSAuthor: Outlyer | Version: 1.0.0 | License: MIT | Categories:
This integration monitors the Relational Database Service (RDS) on AWS. Amazon RDS provides a managed relational database service with a choice of six popular database engines: Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server.
This integration provides two plugins for monitoring your RDS instances:
- A discovery plugin that will list all of your RDS instances in Outlyer for monitoring
- A check that uses the Cloudwatch APIs to monitor each RDS instance in Outlyer
Once enabled you will see your RDS instances with all their metadata and labels in the host map in Outlyer, and a dashboard of all the key metrics across your RDS instances in your AWS account.
A full list of available Cloudwatch metrics for the RDS is available here.
|aws.rds_burstbalance_max||Gauge||region, engine||Percentage||The percent of General Purpose SSD (gp2) burst-bucket I/O credits available.|

|aws.rds_cpucreditbalance_max||Gauge||region, engine||Count||The number of earned CPU credits that an instance has accrued since it was launched or started.|
|aws.rds_binlogdiskusage_max||Gauge||region, engine||Bytes||The amount of disk space occupied by binary logs on the master.|
In order for this integration to run, you must create an IAM role and access keys for the plugin to connect to your AWS RDS APIs and AWS Cloudwatch metrics:
- To get started, open the AWS Management Console
- Click the IAM tab.
- Click the Create a New Group of Users button.
- Enter a Group Name called Outlyer.
- Select the Read Only Access Policy Template then click Continue.
- Click the Create New Users tab.
- Enter a new User Name called Outlyer and click Continue and then Finish.
- Click Show User Security Credentials.
- Copy and paste your Access Key Id and the Secret Access Key somewhere safe.
There are two plugins:
rds-discovery.pyuses the Outlyer agent’s instance discovery mechanism to automatically discover all the RDS instances in a specified region
aws-rds.pyis deployed as a standard check runs against each RDS instance discovered in the discovery plugin
The discovery plugin must be currently deployed manually to disk on an agent. The plugin must be put in the agent’s
plugins folder and
a discovery check YAML file must be configured in the agent’s
conf.d folder. An example of the YAML configuration file is shown below:
discovers: rds-discovery: command: '/opt/outlyer/embedded/bin/python3 /etc/outlyer/plugins/rds-discovery.py' interval: 300 disabled: false timeout: 120 #labels: # environment: 'prod' #metric_labels: # - 'environment' #check_command: check_interval: 30 env: AWS_ACCESS_KEY_ID: <AWS_ACCESS_KEY_ID> AWS_SECRET_ACCESS_KEY: <AWS_SECRET_ACCESS_KEY> AWS_REGION: <AWS_REGION>
Once running you should see almost immediately all your RDS instances in the host view of the Outlyer UI. After that you can then deploy the
aws-rds.py monitoring check to monitor all of the instances via Cloudwatch. It is recommended that you use the check selector
to ensure the check runs against all your RDS instances.
It is recommended that both plugins run at 5 minute intervals to avoid significant charges on your AWS account bills
Both plugins must set the following variables to run:
AWS_ACCESS_KEY_ID: The AWS Access Key copied above
AWS_SECRET_ACCESS_KEY: The AWS Secret Key copied above
AWS_REGION: The AWS Region your RDS instnces are running in
In addition the following variables can be set to override the default values:
time_range: The time range in minutes to query your metrics over. By default this is set to the last 10 minutes but if you run your functions rarely this can be set to longer for testing purposes.
