Novij Monitoring Agent Patch Notes

Changes

• Removed the single-Relay dependency from Telegram payments and NTP defaults:

the agent now uses C++ SDK multi-seed discovery, Network Registry, compatibility/health checks, a 48-hour local checkpoint, and safe failover across active Relays. The legacy relay_url remains an optional compatible seed override.

• Fixed fragmented Storage WebSocket text responses: the C++ SDK now waits for

the final continuation frame, preserves fragment order, and builds without the false GCC uninitialized-opcode warning.

• Removed the modern CMake warning from vendored yaml-cpp 0.8.0: a

reproducible patch step raises the dependency policy minimum to 3.5 without disabling diagnostics.

• Telegram daily reports are now sent only within the configured reports.daily.send_window_minutes; stale pending daily reports expire instead of being delivered later in the day.
• The daily report no longer marks the server as Needs attention for a single 24h CPU peak when average CPU usage is healthy and there are no active incidents.
• Healthy daily reports now use a Summary section instead of What needs attention.
• Fixed agent crashes during Telegram daily report payment errors: pending notifications with null payment fields now stay queued, write the failure to the journal, and the service keeps running.
• The service loop now survives an unexpected single monitoring iteration failure instead of falling into a systemd restart loop.
• Improved doctor: it now checks whether the systemd service is active and surfaces the latest Telegram payment failure instead of reporting a misleading OK.
• Strengthened service-key validation: the delegate secret is now checked against the DSR delegate_pubkey, and unusual service metadata is surfaced by doctor as a warning without blocking payments.
• Added update channel selection: latest and stable.
• Added --channel stable support to novij-monitoring-agent update.
• Added updates.channel to the configuration; the default value is latest.
• Reduced novij-monitoring-agent update network usage: checks download only the small VERSION file, and installing a new version no longer downloads install.sh or runs apt-get update.
• The package-site installer now skips apt-get update by default when upgrading an already installed agent; first installs keep the previous behavior.
• Split recent and stable builds on the package site:
• latest/ and releases/
• stable/ and stable-releases/
• Added stable promotion: a build from the last three releases becomes stable after 7 days without a newer publication.
• Added Russian and English patch note links to package pages.
• Added shared Codex AI instructions for releases, stable/latest channels, auto-updates, and patch notes.

Update

• No action is required to keep the previous behavior: the default channel is latest.
• To keep auto-updates on stable builds only, set:

updates:
  channel: "stable"

• One-off update from the stable channel:

sudo novij-monitoring-agent update --channel stable

• Check for an available update without downloading the .deb:

novij-monitoring-agent update --check

• To control apt index refresh manually when installing from package-site:

curl -fsSL https://packages.novij.tech/agents/monitoring/install.sh | sudo env NOVIJ_APT_UPDATE=always bash
curl -fsSL https://packages.novij.tech/agents/monitoring/install.sh | sudo env NOVIJ_APT_UPDATE=never bash

Compatibility

• Existing relay_url and storage_ws_url values remain supported; empty

values enable automatic Network Registry selection.

• A service-key without relay_url is now valid; a legacy relay_url is

still accepted as a bootstrap override.

• Existing configs without updates.channel continue to work and are treated as latest.
• Existing installer usage without NOVIJ_PACKAGE_CHANNEL continues to install latest.
• The stable channel requires a package-site publication in stable/.
• The first update from an older build may still use the previous installer path; new builds use the lighter self-update flow.
• NOVIJ_APT_UPDATE defaults to auto: first installs refresh apt indexes, upgrades of an installed agent do not.
