Opservo
Opservo monitors Linux servers for teams without a dedicated SRE. One command installs a lightweight agent (under 10 MB, open source, Apache-2.0) that needs no inbound ports and is read-only by default. Within minutes it inventories everything running on the server (systemd services, Docker containers, PM2 apps, databases, nginx/Apache sites, SSL certificates and logs) and gives each server a 0–100 health score.
Instead of more graphs, Opservo explains problems in plain English: why a server is slow, what changed before an incident, and the exact command that fixes it. An AI chat answers questions like "why is my API server slow?" from that server's live data. On paid plans you can turn on remote fixes per server; every command is signed, approved by you and logged.
Also included: uptime and SSL monitoring, on-call rotations, incident tracking, public status pages and security findings. Free for 2 servers, with paid plans priced per server.
