Alerts > History is where an operator looks back at what happened, and its
table hid the answer. At a 1024px window the card is 600px wide and the Message
column got about 110px, so rows read "Docker servi…" and "Last reading…". Three
action buttons stacked on three lines made every row 75-105px tall, while
Duration, Status and Actions held wide, mostly empty tracks. The row has no
disclosure of its own, so the only way to read the message was to hover.
- Resource and Message now wrap inside a line-clamp-2 wrapper below an 80rem
card (the wrapper sets whitespace-normal itself, because .table-fixed td
forces nowrap) and return to a one-line clamp from 80rem, where the message
track is wide enough and the old 39px row is kept.
- The four density blocks are re-derived from measured natural widths
("08:27 AM" in a 14px monospace, the Resource/Severity/Duration headers, a
119px "acknowledged" badge, three one-line actions at 177px, Type and Node)
at the narrowest card each density serves. The time column is headed "Time",
as on the phone card, because "Timestamp" needed 93px.
- Message keeps a two-line minimum height. The windowing hook sizes its
spacers from one measured row; scrolling a 600-row history in 60px wheel
steps moved a tracked row exactly the scroll distance with uniform 49px rows
and showed 46 jumps up to 20px once rows were 39px and 49px.
Measured in a real browser against an unpatched build of the same tree, at nine
windows from 1024px to 2000px with a 12-hour locale: messages ending in an
ellipsis fell from 82 of 88 rows to 24 of 90 at 1024px, 54 to 17 at 1280px, 24
to 8 at 1440px and 32 to 4 at 1700px; the median row fell from 75px to 49px
from 1280px to 1700px; no time cell or header ended in an ellipsis at any
width. The phone card list is untouched, and Timeline and Resource open and
close as before. Cards under 600px stay cramped; a container-driven switch to
the card list is the remaining fix.
Proofs: the row test pins the wrapper classes, Alerts.helpers pins the header
and class constants, App.architecture asserts the pixel minimums per density,
the 18% Message floor and that each block sits inside its 50rem, 64rem or
80rem container query. Putting the base row markup, header, widths or 50rem
switch point back fails the matching proof.
Pulse
Real-time Proxmox, Docker and Kubernetes monitoring that finds what needs attention.
Pulse is a self-hosted monitoring workspace for Proxmox, Docker, Kubernetes, TrueNAS, physical and virtual machines, and early-access VMware vSphere environments. It combines live infrastructure state, history, alerts, recovery visibility, and scheduled health checks without requiring a conventional enterprise monitoring stack.
Why Pulse
- It watches between visits. Alerts and Pulse Patrol find failed backups, capacity pressure, restart loops, unhealthy containers, clock drift, and other problems that dashboards cannot surface when nobody is looking.
- It keeps each platform familiar. Proxmox, Docker, Kubernetes, TrueNAS, vSphere, and machines have dedicated views, backed by one shared resource model for search, alerts, history, and investigation.
- It stays operator-controlled. Credentials are encrypted at rest, API tokens are scoped, agent commands are disabled by default, and governed fixes require the configured policy and approval path.
Platform coverage
| Platform | Coverage |
|---|---|
| Proxmox VE, PBS, and PMG | Nodes, guests, storage, backups, replication, Ceph, mail gateways, and alerts |
| Docker and Podman | Hosts, containers, Compose projects, Swarm services, health, images, and updates |
| Kubernetes | Clusters, nodes, workloads, pods, services, storage, and events through the unified agent |
| TrueNAS SCALE and CORE | Pools, datasets, disks, snapshots, replication tasks, apps, VMs, and alerts |
| Linux, Windows, and macOS machines | Host health, filesystems, networking, temperatures, RAID, and availability through the unified agent |
| VMware vSphere | Early-access inventory, hosts, clusters, VMs, datastores, networks, snapshots, and recovery context; validate against your own vCenter before production use |
Platform pages keep storage and recovery information beside the infrastructure it belongs to. Alerts, Actions, and Patrol remain cross-platform views.
Patrol: monitoring that does rounds
Pulse Patrol runs scheduled checks across the current state and recent history of your infrastructure. Community installations can use a local model or their own AI provider for watch-only analysis. Pulse Pro adds investigation and policy-bound fixes with approval, verification, and an audit trail.
Pulse also includes an interactive Assistant and an MCP adapter for external clients such as Claude Code and OpenCode. Both sit on top of the same scoped inventory, metrics, alert, storage, and governed-action contracts.
Quick start
Choose an exact version from the latest release and keep that version pinned during installation.
Docker
docker run -d \
--name pulse \
-p 7655:7655 \
-v pulse_data:/data \
-e PULSE_DEPLOYMENT_METHOD=docker_run \
--restart unless-stopped \
rcourtman/pulse:vX.Y.Z
Open http://<your-ip>:7655 and follow the bootstrap-token setup. Docker host
monitoring is provided by the unified agent; the Pulse server container does
not need the Docker socket.
Proxmox LXC, Linux, and Kubernetes
The installer is signed. Verify install.sh against the pinned
pulse-installer key before running it:
export PULSE_VERSION=vX.Y.Z
curl -fsSLO "https://github.com/rcourtman/Pulse/releases/download/${PULSE_VERSION}/install.sh" &&
curl -fsSLO "https://github.com/rcourtman/Pulse/releases/download/${PULSE_VERSION}/install.sh.sshsig" &&
ssh-keygen -Y verify \
-f <(printf '%s\n' 'pulse-installer namespaces="pulse-install" ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIMZd/DaH+BldzOkq1A8KVTcFk73nAyrE8aJOyf7i00jm pulse-installer') \
-I pulse-installer \
-n pulse-install \
-s install.sh.sshsig < install.sh &&
bash install.sh --version "${PULSE_VERSION}"
Paste the whole block: installation stops if either download or signature verification fails. Do not run the final command separately to bypass a failure.
The GitHub installer installs the Pulse server. Install and upgrade agents (including v5-to-v6 agent upgrades) with the per-host command generated under Settings → Infrastructure → Install on a host.
Do you need an agent?
Often not. Proxmox VE, PBS, and PMG are monitored through the Proxmox API with a read-only token, so no Pulse host agent is required. The generated setup script creates a privilege-separated monitoring user. Install the unified agent only where you want data the platform API cannot provide, such as host SMART health, temperatures, Docker hosts, or standalone machines.
API-only does not mean guest-agent-free. VM filesystem and memory requests through QEMU Guest Agent can share the channel used by freeze-enabled backups. Read-only permissions do not prove backup safety. Do not add permissions, enable or restart an agent, or send manual guest-agent probes during a backup, freeze or thaw. Use the existing backup safety precaution. Stopping Pulse also stops its monitoring and alerts. An OK backup task does not prove successful thaw.
The agent is operator-controlled by design. Command execution is off by
default, the local listener binds to localhost, and generated systemd units
ship hardened. On Linux, the installer's --least-privilege profile runs the
service as a dedicated non-root user, with optional scoped sudo grants for
the few collectors that need elevation. The
agent security model documents exactly what the
agent can and cannot do at each privilege level.
Important
GitHub release assets and
rcourtman/pulseimages are Community builds. Relay, Pro, and eligible legacy customers should use the private image or Linux archive provided by the Pulse download portal. Replacing a private Pro runtime with a public Community build removes its private runtime hooks.
Editions
- Community — self-hosted monitoring, seven days of metric history, core SSO, update alerts, and Patrol with your own provider or local model.
- Pro — Community plus Patrol investigation, governed fixes, ninety days of history, centralized agent profiles, RBAC, audit logging, and reporting.
- MSP — for managed service providers: one Pulse Account running many client workspaces, each with an isolated Pulse runtime — separate dashboards, alerts, users, audit history, and reports. Free sixty-day two-client evaluation at Pulse for MSPs.
Relay is no longer sold. Existing Relay subscribers receive Pro features at their current price for as long as their subscription continues. Existing paired phones keep working until 31 March 2027. Relay connects the app, not the web UI. Use your own VPN or tunnel for remote web access. For phone alerts, add an ntfy, Gotify or Pushover destination and open Pulse in your phone's browser.
Core self-hosted monitoring is not gated by monitored-system or child-resource volume. See the runtime-aligned capability reference and current plans for details.
