Linux & Unix host monitoring

The SSH sensor logs into Linux/Unix hosts (password or private key, stored encrypted) and reads host health — from any probe, Windows or Linux.

Host health

• CPU, memory, per-mount disk usage, uptime
• systemd service watchdog: alert when a required service is not active
• Warn/critical thresholds with automatic recovery alerts

Custom command checks

Run any command and assert on its exit code and/or output — works for anything with an SSH interface, including network appliances.

raid status   →  expect "clean" in output
cert expiry   →  expect exit code 0
queue depth   →  expect output < 1000

Security

• Credentials are encrypted at rest and never shown back in full (masked fields)
• A read-only/limited account on the monitored host is all the sensor needs
