# Infrastructure metrics

### AWS 

If you are running on AWS we recommend setting up Cloudwatch alarms for the following metrics

- AWS Aurora
  
  - Alert when `CPUUtilization` is above 80% utilization. Reference [here](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.AuroraMonitoring.Metrics.html).
  - Alert when `FreeableMemory` is below 80% utilization of the total memory. Reference [here](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Aurora.AuroraMonitoring.Metrics.html).
- AWS Elasticache
  
  - Alert when `DatabaseMemoryUsagePercentage` is above 80%. Reference [here](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/CacheMetrics.Redis.html).
  - Alert when `EngineCPUUtilization` is above 80%. Reference [here](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/CacheMetrics.Redis.html).
- AWS ALB
  
  - Alert when `UnHealthyHostCount` is above 50% of the desired host count for over 2 mins. For example: If you have set desired task count for `tines-app` to be `2`, then your set the threshold for `UnHealthyHostCount` to be `1`. Reference [here](https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/elb-cloudwatch-metrics.html).
  - Alert when `HTTPCode_ELB_502_Count` is above 5 requests. This metric indicates that your load balancer cannot successfully route requests to its backends and you traffic has been dropped. Reference [here](https://repost.aws/knowledge-center/elb-alb-troubleshoot-502-errors).
    
    - If you see frequent occurrences of this alert then increase your desired tasks count.
- AWS ECS Fargate
  
  - Alert when `CPUUtilization` is consistently (5 minutes or more) above 80%. Note: this could also be a sign that you may need to increase the number of tasks on the service. In other words, scale horizontally. Reference [here](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Best_Practice_Recommended_Alarms_AWS_Services.html#ECS).

If you find that the alert is frequent and any of the metrics are consistently above the mentioned thresholds then its best to scale up the instance type. For example: If you are on `db.r7g.large` , you should upgrade the Aurora cluster to `db.r7g.xlarge`.

### Non-AWS setup 

For now AWS setups our recommendations are similar to AWS setups. For example

- You should setup monitoring for your storage system if it is occupying more than 80% of total storage.
- You should setup monitoring if the CPU utilization of your compute systems is consistently above 80%.
