Know what a server is doing—and whether its agent is still alive.
Sentinely Pulse is Linux server monitoring: a lightweight agent reports CPU, memory, disk, network, services and ports, and Sentinely alerts you when a threshold is crossed or the agent goes quiet.
Move between a plain-language health view and the technical evidence needed to investigate.
What does Pulse track?
Core system metrics
Collect CPU, memory, disk, network, load, uptime, and process-count metrics on a regular interval.
Services and ports
Inspect reported services, top processes, and listening ports when the selected agent supports them.
Agent freshness
Distinguish a stale monitoring agent from a healthy server instead of treating old data as current.
Threshold incidents
Create alert rules for infrastructure metrics and follow incidents through acknowledgement and resolution.
Clarity Mode
Translate technical conditions into a simpler operating summary for founders and client stakeholders.
Controlled agent releases
Distribute private, checksummed agent builds through authenticated download routes.
Register, verify, and report with scoped credentials.
The installation flow creates an account-scoped API key, returns an authenticated agent download, and validates every metrics payload before it reaches time-series storage.
How do I set up server monitoring with Pulse?
Connect the first server during the trial and confirm the first report and alert.
Add a server
Create a server in Sentinely. It generates an account-scoped API key and a one-line install command for that server.
Run the install command
Run the command with sudo on the server. It needs curl and outbound HTTPS on port 443, and downloads a private, checksummed agent build.
Set a threshold and test it
The server appears once the agent reports. Add an alert rule for CPU, memory or disk and send a test notification.
Pulse questions
What does Pulse monitor on a server?
CPU, memory, disk, network, load, uptime and process count, plus reported services, top processes and listening ports where the agent supports them.
How do I install the Pulse agent?
Add a server in Sentinely, copy the one-line install command and run it with sudo. The server needs curl and outbound HTTPS on port 443.
What happens if the agent stops reporting?
Pulse marks the agent as stale, so old data is never shown as the current state of a healthy server.
Is Pulse an APM or log search tool?
No. Pulse is host-level server monitoring. It does not trace requests, profile code or search logs.
How many servers can I monitor?
Indie includes 1 server, Agency 5 and Scale 50. Every plan starts with a 14-day trial.
What is Clarity Mode?
A plain-English view that explains what a server problem means, for founders and clients, next to the technical metrics your team needs.
