AWS - DynamoDB CloudWatch Opspack

Amazon DynamoDB is a fast and flexible NoSQL database service for all applications that need consistent, single-digit millisecond latency at any scale. It is a fully managed cloud database and supports both document and key-value store models. Its flexible data model and reliable performance make it a great fit for mobile, web, gaming, ad tech, IoT, and many other applications. This is just part of Opsview Monitor's AWS Monitoring capabilities.

What Can You Monitor

Opsview Monitor's AWS DynamoDB Opspack provides the most up-to-date metrics for your database needs. DynamoDB is built for high performance with seamless scalability and lets our Opspack track all the important metrics to keep your database up and running. The DynamDB Opspack can be used with many different AWS Opspacks to paint a larger picture of your AWS environment. AWS Service Statuses help you track the availability of your DynamoDB instances in various regions.

Note: This Opspack knows when it was last run, so when testing the results in the troubleshoot section, you will need to wait a couple minutes each time you recheck the results. The time frame that is searched for is based around the last time the Opspack ran, so running it too quickly will result in no data being found and the service check going into an unknown

Notes

This Opspack knows when it was last run, so when testing the results in the troubleshoot section, you will need to wait a couple minutes each time you recheck the results. The time frame that is searched for is based around the last time the Opspack ran, so running it too quickly will result in no data being found and the service check going into an unknown.

Prerequisites

There are two ways of adding your authentication credentials to the host. We recommend adding the access key and secret key directly using the variable 'AWS_CLOUDWATCH_AUTHENTICATION'. You can also add the access key and secret key to a file (default /usr/local/nagios/etc/aws_credentials.cfg) in the following format:

[default]
aws_access_key_id = "Your Access Key Id"
aws_secret_access_key = "Your Secret Key Id"

Setup and Configuration

Step 1: Add the host template and add the 'Cloud - AWS - DynamoDB CloudWatch' Opspack to the host running the DynamoDB software.

Add host template

Step 2: Add and configure the host Variables tab, add in AWS_CLOUDWATCH_AUTHENTICATION with either the file location or the access key and secret key depending on your preferred way of supplying the access credential. Add the region you hosted in. Then add and configure the 'AWS_DYNAMODB_TABLE_NAME' by adding the instance name.

Add variable

Step 3: Reload and view the DynamoDB statistics

Prerequisites

To be able to monitor AWS CloudWatch services you need to add your AWS credentials to your Opsview Monitor server.

We recommend adding your AWS Access Key ID and AWS Secret Key ID to the default location:

/opt/opsview/monitoringscripts/etc/plugins/cloud-aws/aws_credentials.cfg

This credentials file should be in the following format:

[default]
aws_access_key_id = "Your Access Key Id"
aws_secret_access_key = "Your Secret Key Id"

If you are not using the default path, you will then need to assign your path to the variable: AWS_CLOUDWATCH_AUTHENTICATION.

Setup and Configuration

To configure and utilize this Opspack, you need to add the 'Cloud - AWS - DynamoDB CloudWatch' Opspack to your Opsview Monitor system

Step 1: Add the Host Template

Add the Cloud - AWS - DynamoDB CloudWatch Host Template to your Opsview Monitor host. Add the Primary Hostname/IP. This can be the Public DNS (IPV4) or IPV4 Public IP from the Description tab of an EC2 instance in the EC2 Console in AWS.

For more information, refer to Opsview Knowledge Center - Adding Host Templates to Hosts.

Step 2: Add and configure variables required for this host

Variable Description
AWS_CLOUDWATCH_AUTHENTICATION Authentication details for CloudWatch. The Value is not used and therefore can be set to anything. Either override the File Path with the location of your credentials file, or override the Access Key and Secret Key arguments (this approach is recommended as the values will be encrypted). Optionally, override the Region (default: eu-west-1) with the location of your instance if you are not using the default region.
AWS_DYNAMODB_TABLE_NAME The name of the database you want to monitor in AWS

For more information, refer to Opsview Knowledge Center - Adding Variables to Hosts.

Step 3: Apply changes and the system will now be monitored
