## What it is
Opserver is Stack Exchange's open-source monitoring dashboard, built as an ASP.NET Core web application. It provides a unified view of servers, SQL Server, Redis, Elasticsearch, HAProxy, exception logs, and other infrastructure systems.

## Use cases
- monitor sql server clusters and instances from a web dashboard
- dashboard for redis and elasticsearch health
- view cpu memory and network stats for all servers
- monitor haproxy and cloudflare dns status
- self-hosted infrastructure monitoring dashboard
- track exception logs from stackexchange.exceptional

## When to choose
- you run a dotnet/aspnet core stack and want a lightweight self-hosted monitoring dashboard
- you need dashboards for sql server, redis, or elasticsearch without a heavy observability platform
- you already use bosun, orion, or signalfx and want a consolidated view

## When to avoid
- you need full metrics collection, storage, and alerting pipelines rather than a dashboard
- you want a plugin ecosystem or active rapid development
- you need monitoring for non-.net-friendly or exotic systems not on its supported list

## Facets
- artifact type: application
- maturity: maintenance
- function: monitoring, alerting
- domain: monitoring, databases, self-hosted
- platform: windows, self-hosted, dotnet
- tags: monitoring-dashboard, sql-server, redis, elasticsearch, haproxy, pagerduty, aspnet-core, stack-exchange, dashboard, devops, macos, linux, docker
