Amazon CloudWatch monitors your Amazon Web Services (AWS) resources and applications you run on AWS in real time. Use the Coralogix destination to easily forward metrics for your AWS resources to Coralogix using Telegraf.
This guide demonstrates how to:
Use CloudWatch to collect and track metrics and send them to Coralogix using Telegraf
Visualize metrics in your Coralogix dashboard
Import pre-built dashboards and set up alerts in your Coralogix account
Metrics Collection
There are two ways of sending AWS service metrics to Coralogix:
Poll CloudWatch metrics using Telegraf. Opt for this if you are already using this shipper or seeking to reduce costs. The instructions below guide you through this option.
1. Create a configuration file. The example below reads and sends RDS and ElastiCache metrics to Coralogix in 5-minute intervals.
# Global tags can be specified here in key="value" format.
[global_tags]
dc = "us-east-2"
user = "$USER"
env = "CoE"
# Configuration for telegraf agent
[agent]
interval = "10s"
round_interval = true
metric_batch_size = 1000
metric_buffer_limit = 10000
collection_jitter = "0s"
flush_interval = "10s"
flush_jitter = "0s"
precision = "0s"
hostname = ""
omit_hostname = false

# ## The minimum period for Cloudwatch metrics is 1 minute (60s). However not
# ## all metrics are made available to the 1 minute period. Some are collected
# ## at 3 minute, 5 minute, or larger intervals.
# ## See https://aws.amazon.com/cloudwatch/faqs/#monitoring.
# ## Note that if a period is configured that is smaller than the minimum for a
# ## particular metric, that metric will not be returned by the Cloudwatch API
# ## and will not be collected by Telegraf.
# #
# ## Requested CloudWatch aggregation Period (required)
# ## Must be a multiple of 60s.
period = "5m"
#
# ## Collection Delay (required)
# ## Must account for metrics availability via CloudWatch API

#
# ## Recommended: use metric 'interval' that is a multiple of 'period' to avoid
# ## gaps or overlap in pulled data
interval = "5m"
# Case sensitive check https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/aws-services-cloudwatch-metrics.html

In order to send your data to Coralogix, you are required to declare the following variables in your configuration:
service_address: In order to send metrics to Coralogix, you will need to include your account’s specific domain in the Coralogix endpoint: otel-metrics.<domain>:443.
For example, if you are located in Region US1, your service_address should appear as: otel-metrics.coralogix.us:443.
private_key: Access your Coralogix private key. Your key is recorded in the override file as a secret in order to ensure that this sensitive information remains protected and unexposed.
application & subsystem: Customize and organize your data in your Coralogix dashboard using application and subsystem names.
Note: Find out more about different attributes available for the CloudWatch statistics input plugin here.
2. If you would like to add additional dimensions to your CloudWatch metrics, add them in the global_tags section of your configuration, as in the example below.
[global_tags]
dc = "us-east-2"
user = "$USER"
env = "CoE"
3. Save the configuration file and restart Telegraf. You should now see your metrics on your Coralogix dashboard.
Dashboard
1. Download and import the Telegraf version of your RDS dashboard.
To validate your configuration, access your Coralogix – Grafana dashboard.
On the right-hand corner of your dashboard, click on the Grafana drop-down tab.
2. Once you’ve accessed your Coralogix-Grafana dashboard, click on Explore tab in the left-hand browser.
3. Click on the drop-down arrow of the Metrics browser and input rds (RDS metrics) and elasti_cache (ElastiCache metrics) in the “Select a Metric” column.
Oh no!We didn’t find anything for “”,
