Study Notes
- SPLK-4001 Dumps relate to the Splunk 011y Cloud Certified Metrics User certification
- Further details available at: https://www.certleader.com/SPLK-4001-dumps.html
Analytic Functions
- The maximum function, when used as a transformation over 24 hours, identifies peak page visits
maximum(24h, counters ("page.visits"))
OpenTelemetry Collector Ports
- gRPC uses port 4317
- SignalFx uses port 9080
- Fluentd uses port 8006
Configuration Files Location
- Splunk's OpenTelemetry Collector stores configuration files in
/etc/otel/collector/
on Linux
Saving Charts in Chart Builder
- To save a chart, select a dashboard
- Dashboards can be new or existing
Ephemeral Infrastructure Alerting
- Configure Auto-Clear Alerts with an appropriate time period in Alert Settings
Troubleshooting OpenTelemetry Collector
- Add "logging" to the metrics receiver pipeline's exporters section
Detector Notification Issues
- If a detector isn't sending email notifications but generating alerts in the UI, It's likely due to a muting rule
Subscribing to Built-in Detectors
- Outbound notifications can be configured
Dashboard Group Permissions
- Write access should be restricted during dashboard group creation. i.e. "Only me"
Detector Resolution
- Detectors operate at native resolution which can be determined from the data source
Alert Subscriptions
- The reason to subscribe to an alert is to receive email notifications when a detector is triggered
Smoothing Spiky Metrics
- To smooth spiky
cpu.utilization
, useMean (Transformation)
Reducing Detector Flapping
- Configure a duration or percent of duration for alerts
- Apply Smoothing e.g, rolling mean to the input data for the detector instead
Reducing MTS Count in Plots
- Add a filter to narrow the scope of the measurement
Event Feed Chart Key points
- Should include custom events from external sources
- Should include events created when a detector clears an alert
- Should include events created when a detector triggers an alert
Refining Metric Searches
- Searching for
host: test-*
returns metrics with ahost
dimension starting withtest-
Handling Delayed Data Points
- Modify the
Max Delay
setting in a detector
Kubernetes Navigator Features
- It includes features like Map, Nodes, Workloads, Node Detail, Workload Detail, Pod Detail, Container Detail.
Local Data Links
- Anyone with write permission for a dashboard can add local data links that appear on that dashboard
- Local data links are available on only one dashboard
Common OpenTelemetry Errors
- A
401 (UNAUTHORIZED)
error indicates a misconfigured realm or access token
Identifying Server Utilization Increases
- Timeshift analytics function is needed
Best Practices for Creating Detectors
- View data at the highest resolution.
- Have a consistent value.
- View the detector in a chart.
- Have a consistent type of measurement.
Organization Metrics
- Organization metrics provide insights into system usage, limits, data ingestion, and token quotas
- Organization metrics are included for free
- A user can plot organization metrics and set up alerts like other metrics.
Time Delta Rollups
Lag
will display the time delta between a datapoint being sent and a datapoint being received
OpenTelemetry Components
- Processors allow modification of metadata
Cloning Detectors
- New signals added to a cloned detector don't reflect in the original detector or chart
