OCI 1Z0-1111-25 glossary of logs, metrics, alarms, tracing, and incident response terms.
On this page
Use this glossary to clean up high-confusion OCI observability terms before you go back into mixed sets. On this exam, vocabulary mistakes usually hide a signal-selection or workflow-stage mistake.
High-value terms
Term
What it means here
Why it matters on the exam
Alert rule
the condition set that decides when an operator should be notified
alert quality is a core tie-break on this exam
APM
application performance monitoring used to inspect application behavior more deeply
it often wins when the issue is request-path latency, not simple health
Log Analytics
OCI service for analyzing logs at scale and extracting patterns
this is different from raw log collection
Metric
a numeric measurement collected over time
metrics are often the best first lane for detection
Notification topic
the routing target used to fan alerts out to subscribers
routing is not the same as diagnosis
Signal quality
how useful a signal stream is for spotting real issues without excess noise
strong answers improve quality, not just quantity
Telemetry
operational data emitted so systems can be observed
telemetry is the raw material, not the final response path
Threshold
the numeric or logical boundary that triggers a response
weak thresholds create noise or blind spots
Trace-style visibility
request-flow insight that helps explain where time or failure occurred
traces help localize path-level bottlenecks
Visibility gap
missing or weak operational coverage that slows diagnosis
many bad answers create or ignore these gaps
Common confusion pairs
Pair
Clean separation
Metric vs log
metrics summarize numeric state over time, logs capture event or message detail
Logging vs Log Analytics
Logging collects and stores events, Log Analytics helps analyze them at scale
Monitoring vs APM
Monitoring tracks broad health, APM goes deeper into application behavior and path performance
Collection vs notification
collection gathers the data, notification routes the alert after conditions are met
