I am using cloudwatch dashboards to have and aggregated view of various services running for the application. I have number widget for the EnvironmentHealth metrics which displays the enumerated values but not the health codes as OK, WARN .. On the beanstalk monitoring option I can see the service health but want the same on dashboard. Please help.

CloudWatch metrics for ElasticBeanstalk EnvironmentHealth only returns numbers. 0 is OK, 1 is info, 15 warning etc.
Not sure this is the best way but using custom widget with a lambda funcation works fine. The lambda function get the info of EB status and return it to CW dashboards.
Create Lambda function
I used python 3.9. Default setting is ok but note attach lambda IAM policy AWSElasticBeanstalkReadOnly to get EB status.
Lambda python code is below:
- set
EnvironmentNamefor your EB env - font size="56 px" color="#444444" are same as CW dashboard widget
- Create in the same region as EB env.
import boto3
def lambda_handler(event, context):
client = boto3.client("elasticbeanstalk")
response = client.describe_environment_health(
EnvironmentName="<your-env-name>", AttributeNames=["HealthStatus"]
)
output = (
"""<font size="56 px" color="#444444">"""
+ response["HealthStatus"]
+ """</font>"""
)
return output
Create Custom widget on CloudWatch dashboard
Add widget -> Custom widget -> Next -> Select the Lambda function above -> Create widget
This is my dashboard.
