01
Host identity
Reads hostname, OS, kernel, CPU architecture, IP addresses, and agent version.
Agent security
What the Fivenines agent does on your servers.
The Fivenines agent is an open-source Linux monitoring agent. It collects infrastructure telemetry locally, then pushes metrics to Fivenines over HTTPS. It is not a remote shell, not an inbound daemon, and not a command-and-control channel.

Agent model
The agent runs locally and talks out to Fivenines. Your server does not need to expose an agent port to the internet.
1
Install
Install
Creates the agent service, local config, and host token.
2
Collect
Collect
Reads metrics and enabled module data from the local host.
3
Push
Push
Sends telemetry to Fivenines API endpoints over HTTPS.
4
Config
Receive config
Gets module settings and intervals back from Fivenines.
Access boundary
What the agent can and cannot do
The agent sends operational telemetry out to Fivenines. It does not open a control path back into your server.

What the agent does
Agent reads and sends
02
Resource metrics
Collects CPU, load, memory, swap, disk I/O, partitions, network counters, and temperatures.
03
Process visibility
Reports top process names by CPU and memory usage for troubleshooting.
04
Optional inventory
Can send open ports, package names and versions when those modules are enabled.
05
Optional modules
Can collect Docker, QEMU, Proxmox, PostgreSQL, Redis, NGINX, Caddy, SNMP, RAID, S.M.A.R.T., Fail2ban, and NVIDIA GPU stats when configured.
06
Scoped permissions
Supports user-level install; deeper modules use explicit local access such as Docker socket, read-oriented API tokens, database monitoring views, or constrained sudoers commands.
Frequently Asked Questions
Does the Fivenines agent give Fivenines shell access? +
No. The agent pushes metrics to Fivenines over HTTPS. It does not accept inbound connections, expose SSH access, or run commands sent from the Fivenines dashboard.
Does the agent need sudo? +
The standard installer uses sudo to install a system service. A user-level installer is available without sudo, with reduced coverage for modules that require elevated local read permissions such as S.M.A.R.T. and RAID health.
What data does the agent send? +
It sends host identity, operating system metadata, resource metrics, disk and network counters, top process names by resource use, and optional module metrics you enable such as Docker, Proxmox, PostgreSQL, SNMP, package versions, S.M.A.R.T., RAID, Fail2ban, and GPU metrics.
Can optional integrations be restricted? +
Yes. Optional modules are explicit. For example, Proxmox should use a read-oriented API token, PostgreSQL should use read access to monitoring views, and S.M.A.R.T. or RAID modules can be limited to specific sudoers commands.
Inspect the agent, then install it when you are ready.
The agent is open source, the install path is documented, and the permission model is explicit. Start with the live demo or create a trial when you want to test it on a real server.
