# System Metrics and Alarms

For managed environments (cloud and managed on-premise), Grafana, Prometheus, and several exporters are deployed to the environment to aggregate system metrics, render them in custom dashboards and send alerts when deviations or dangerous values are detected.

Some of the systems that are monitored include:

* Load balancer
* Redis
* Postgres
* Postgres worker queue
* Redis worker queue
* Workflow executions
* Connect Proxy Requests
* Microservices

### Load balancer

Metrics and alarms include:

* Request count / response time
* HTTP response codes
* Connection count
* Bytes processed
* TLS errors

### Redis

Metrics and alarms include:

* Uptime
* Clients
* Memory usage
* Commands executed/second
* Hits/misses per second
* Total items per database
* Network I/O
* Expiring vs non-expiring keys
* Expired/evicted
* Command calls/second
