A heartbeat-registered site that has never sent a full report now has
LastReportReceivedAt = null instead of the year-0001 sentinel. TimestampDisplay
accepts DateTimeOffset? and renders null as a placeholder ('awaiting first
report') rather than a ~2000-year-stale date. Cross-module: HealthMonitoring +
CentralUI.
The Test Run sandbox and Monaco analysis modelled a script API that had
drifted from the site runtime's ScriptGlobals, so real scripts failed to
compile in Test Run. Realign both to the runtime surface
(Instance/Scripts/ExternalSystem/Attributes/Children/Parent) and drop the
duplicate ScriptHost stub so the two cannot diverge again.
- Script calls (Scripts.CallShared, Instance.CallScript, Route.To().Call)
accept an anonymous object instead of a hand-built dictionary, via a
shared ScriptArgs normalizer; existing dictionary calls still compile.
- Test Run can optionally bind to a deployed instance, so Instance/
Attributes/CallScript route to it cross-site; adds site-side
RouteToGetAttributes/RouteToSetAttributes handlers.
- Adds Test Run panels to the API method and template script editors.
- Fixes the TestDatabaseQuery seed script, which queried a table that
never existed.
Also commits unrelated in-progress work already in the tree: the health
monitoring report loop, site streaming changes, and the Admin/Design
data-connection and SMTP page reorganization.
Dashboard: user-info card demoted; 4 KPI cards (Sites, Data
connections, Templates, API keys) sourced from existing repositories;
3 Quick-action link cards (Health, Audit Log, Templates). Inline
max-width style replaced with Bootstrap utilities.
Health: KPI row condensed to Online / Offline / Sites with active
errors (Total Sites and Total Script Errors dropped). Per-site cards
re-laid out 2-column with each subsection (Data Connections,
Instances & Queues, Errors & Parked Messages) inside Bootstrap
collapse panels collapsed by default. Online / Offline / Primary /
Standby badges paired with shape glyphs (o / * / triangle) plus
aria-label.
EventLogs: filter row wrapped in a Bootstrap collapse toggled by
"Filter options (n active)"; per-row View toggle reveals the full
message in a collapse row; "Keyword" relabeled "Message contains";
all filter inputs gain id+label-for+aria-label; severity badges paired
with a leading glyph; explicit "End of results" terminator on
Load more.
ParkedMessages: Message ID rendered as <code>{first 12}...</code>
plus a clipboard button; per-row View toggle reveals full error;
action buttons get aria-label="{Retry|Discard} message {id}";
in-flight spinner inside the active button.
AuditLog: pagination Next-disabled now uses
_page * _pageSize >= _totalCount via HasMore helper (fixes the
exactly-page-size edge case). Clear filters button added. Entity ID
rendered as code + clipboard button. View/Hide buttons gain
aria-label referencing the entry id. State JSON larger than 1 KB
renders a "View in modal" button instead of the inline overflow.
Add NodeStatus record, IClusterNodeProvider interface, and AkkaClusterNodeProvider
that queries Akka cluster membership for all site-role nodes. HealthReportSender
populates ClusterNodes before each report. UI shows a row per node with
hostname, Online/Offline badge, and Primary/Standby badge. Falls back to
single-node display if ClusterNodes is not populated.
New fields in SiteHealthReport: NodeHostname, DataConnectionEndpoints
(primary/secondary), DataConnectionTagQuality (good/bad/uncertain),
ParkedMessageCount. New collector methods to populate them.
Health dashboard redesigned to match mockup: Nodes | Data Connections
(with per-connection tag quality) | Instances + S&F Buffers | Error
Counts + Parked Messages. Site names resolved from repository.
- Add JoeAppEngine folder to OPC UA nodes.json (BTCS, AlarmCntsBySeverity, Scheduler/ScanTime)
- Fix DataConnectionActor: capture Self in PreStart for use from non-actor threads,
preventing Self.Tell failure in Disconnected event handler
- Implement InstanceActor.HandleConnectionQualityChanged to mark attributes Bad on disconnect
- Fix LmxFakeProxy TagMapper to serialize arrays as JSON instead of "System.Int32[]"
- Allow DataType and DataSourceReference updates in TemplateService.UpdateAttributeAsync
- Update test_infra_opcua.md with JoeAppEngine documentation
Wired ISiteHealthCollector calls for script errors (ScriptExecutionActor),
alarm eval errors (AlarmActor), dead letters (DeadLetterMonitorActor), and
S&F buffer depth placeholder. Added instance count tracking (deployed/
enabled/disabled) to SiteHealthReport via DeploymentManagerActor. Updated
Health Dashboard UI to show instance counts per site. All metrics flow
through the existing health report pipeline via ClusterClient.
