Metrics and history
Sadapp stores timestamped readings by resource and collection source. Inventory tables show the latest usable reading; detail views show available samples and check history.
Sources
- Agent reports host-level metrics from an installed Agent.
- SNMP reports only the counters exposed by the device and selected MIB/profile.
- Monitoring Workers report scheduled ping, website, TCP, DNS, TLS, and supported SNMP checks.
- Local Network Collector reports bounded LAN tasks and local telemetry.
Source tags identify recorded sources; they are not promises that every metric family is available.
Reading the values
CPU percentages are utilization readings or a supported SNMP idle counter converted to utilization. Memory percentage requires both used and total values, or a supported total/available pair. Disk percentage requires used and total capacity for at least one disk. Missing or invalid inputs display n/a, not zero.
Last seen indicates the latest resource observation, not necessarily the latest sample for every metric. Different counters may update on different schedules. A just-enrolled resource may have no readings until the first successful collection.
Improve coverage
- Confirm the source tag matches the intended collector.
- Confirm the source is online and has completed a recent task/heartbeat.
- Check whether the device exports the requested OID or Agent field.
- For SNMP, verify the profile and credentials on the managed Server.
- For Agent metrics, verify the service is active and reporting.
Do not interpret 0% and n/a as equivalent: zero is a valid measured value; n/a means no valid value was received.
