- To setup datadog monitoring via cloudformation
It setups a lambda function that communicate with the monitors and timeboard resource on the datadog api
https://docs.datadoghq.com/api/#monitors https://docs.datadoghq.com/api/#timeboards
The lambda is invoked via cloudformation custom resource. This repo supplies custom resource classes for all the 4 Monitor types. Custom resources have the same exact data structure as the DD api
It uses https://github.com/nordcloud/cfn-encrypt to securely store datadog api credentials
This repository makes use of Troposphere
- clone this repo
git clone [email protected]:nordcloud/cfn-datadog.git
- Build the lambda package
chmod +x create_zip.sh && ./create_zip.sh
- upload
datadog_lambda.zip
to an s3 bucket - get your api and application keys from Datadog
- generate the lambda template
python lambda-template.py > /tmp/lambda.template
- If you have not already set up your encrypt stack do that now ( https://github.com/nordcloud/cfn-encrypt )
- create a stack from your
lambda.template
file - The lambda is now set up and ready to use.
Install the cfn_datadog library
pip install cfn-encrypt
Import the custom resource classes you want to use
from cfn_datadog import (
MetricAlert, MetricAlertOptions, Composite, CompositeOptions,
EventAlert, EvenAlertOptions, ServiceCheck, ServiceCheckOptions,
Timeboard
)
Add a parameter so that you can reference your lambda stack
datadog_lambda_stackname = t.add_parameter(Parameter(
"DatadogLambdaStackname",
Type="String",
Description="Datadog lambda stackname",
))
Add the custom resource to the template: For documentation see datadog api
t.add_resource(MetricAlert(
'Alert2',
query=Join("",["avg(last_1h):avg:system.net.bytes_rcvd{host:",Ref(my_instance),"} < 40"]),
ServiceToken=ImportValue(
Sub("${DatadogLambdaStackname}-LambdaArn")),
name="Bytes received on mytesthost",
message="Some Message @MyDDHandle",
tags=["tag1", "tag2"],
options=MetricAlertOptions(
notify_no_data= True,
no_data_timeframe=50
)
))
t.add_resource(Timeboard(
'ExampleTimeBoard',
ServiceToken=ImportValue(Sub("${DatadogLambdaStackname}-TimeboardLambdaArn")),
TimeboardTitle="testboard",
description="Sample testboard",
