- ServerMonitoringService keeps the SQL Server hosts in step with the monitored
instances (SQLInsight:Servers:IncludeSqlHosts), picks up servers added, paused or
changed in SQLInsight Web within a minute, and runs each server's due areas with
a limit on parallelism. Default intervals: 1 min CPU/memory, 15 min disks and
tasks, 5 min services and events (SQLInsight:Servers:Intervals).
- ServerMonitor: one CIM session per cycle; per-minute samples, disk samples and
the "fuld om ca. N dage" forecast from the stored history, grouped events (read
from where the last read stopped), services and tasks. A missing right makes
only that area "ikke målbar" with the exact reason, logged once per change; a
server that does not answer is notified once, and again when it answers.
Survives an agent restart (samples, boot time, event position).
- SyntheticCheckService runs checks on their interval, opens a SQL login password
sealed for the agent (AgentCredentialKey.OpenContext), looks up the linked
Windows service when a check fails, stores results and findings, notifies with
links to /servere/fund/{id}.
- AgentRequestService hands ServerTest and SyntheticCheckRun to ServerRequestHandler.
- appsettings.json: SQLInsight:Servers and SQLInsight:SyntheticChecks with every
threshold, interval and retention.
