In this blog post, we will look at how to create Synthetics uptime HTTP test in bulk using a CSV file with Splunk Observability Synthetics terraform provider.
This code requires Terraform version 0.13+.
Create a CSV file with details of uptime tests such as Test name, URL, SSL validation, frequency, locations etc. as following:
name,url,ssl_validation,frequency,scheduling_strategy,active,user_agent,locations
Google test,https://www.google.com,true,5,round_robin,true,Splunk (Default),"aws-us-east-1,aws-us-west-1"
Amazon test,https://www.amazon.com,true,5,concurrent,true,Splunk (Default),"aws-us-east-1"
The above example CSV file has following columns, please update the data in each columns as per your requirements:
Column Name
Description
name
Uptime test name
url
Uptime test URL
ssl_validation
Set to true if you want to enable TLS/SSL validation, otherwise set to false
frequency
Specify test frequency number (in minutes)
scheduling_strategy
Set round_robin if you want to enable Round-robin, otherwise set concurrent
active
Set to true if you want to enable test, otherwise set to false
user_agent
Provide the User agent string you want to use, otherwise set Splunk (Default)
locations
Provide the list of locations in double quotes separated by comma, such as "aws-us-east-1,aws-us-west-1" or "aws-us-east-1". Here's the list of available Splunk Synthetics public locations.
Create main.tf terraform file as following in the same folder where your CSV file is located:
terraform {
required_providers {
synthetics = {
version = "2.0.1"
source = "splunk/synthetics"
}
}
}
provider "synthetics" {
product = "observability"
realm = "REPLACE_REALM"
apikey = "REPLACE_WITH_API_TOKEN"
}
locals {
http_test_data = csvdecode(file("${path.module}/<REPLACE_WITH_CSV_FILE_NAME>.csv"))
}
resource "synthetics_create_http_check_v2" "o11y_http_check" {
for_each = { for test_data in local.http_test_data : test_data.name => test_data }
test {
active = each.value.active
frequency = each.value.frequency
location_ids = split(",",each.value.locations)
name = each.value.name
type = "http"
url = each.value.url
scheduling_strategy = each.value.scheduling_strategy
request_method = "GET"
verify_certificates = each.value.ssl_validation
user_agent = each.value.user_agent
}
}
You can modify the above terraform code as per your requirement, and data provided in CSV file.
Please note that, you will have to replace Splunk Observability realm, Splunk Observability API token and CSV file name.
Once terraform and CSV files are ready, run following commands to create HTTP uptime tests from CSV file:
terraform init - to initialize terraform provider
terraform plan - verify there are no errors
terraform apply - Type yes as confirmation
Voila! You have now created uptime tests using CSV data.
If you want to delete existing uptime tests created using terraform automation, please run the following command:
terraform destroy - Type yes as confirmation
