App Management and Dashboard Creation

App and Dashboard Management

• Different application attributes include Owner, Priority, and Status.
• Severity and Type categorize the performance of apps.
• Time Windows, Type, and Severity are essential for understanding data presentation.

Line Charts in Search Results

• Line charts are optimal for multiple series with three or more columns.
• They can also be effective for single series in Fast mode.

Collection of Items

• A collection containing data inputs, UI elements, and knowledge objects is referred to as an app.

Event Indexing

• The 'source' field is stored with events in the index, which helps categorize where data originates.

Creating Dashboards

• It is best to save a search as a report to allow multiple dashboards to reference the same data.

Lookup Tables in Splunk

• To use a lookup table, it must be uploaded to Splunk, and a lookup definition must be created.

Naming Reports

• Reports should be named uniquely and consistently to avoid confusion and overlap.

Unique Value Counting

• The dc(field) stats command function counts the unique values for a specified field.

Time Selection Component

• The time range picker enables users to select specific time frames when performing data searches.

Alert Script Configuration

• Splunk searches for alert scripts in the $SPLUNK_HOME/bin/scripts directory.

Dashboard Editing Options

• Dashboards can be edited by modifying chart types and rearranging dashboard panels.

Efficient Search Performance

• Using the syntax (index=web OR index=sales) offers the most efficient search performance.

Timestamp Storage

• Splunk stores the timestamp value in the field _time during indexing.

Top Command Functionality

• The top command returns the top 10 results, displays output in table format, and includes count and percent columns.

Scheduled Report Data Scope

• Scheduled report data visibility depends on permissions accessible to the report owner.

Specifying Time Range

• To specify a time range in a search, 'earliest=' and 'latest=' are used.

Time Unit Abbreviations

• Acceptable time unit abbreviations include: 'h' (hours), 'day', 'mon' (months), 'yr', 'y' (years), 'w' (weeks), 'd' (days), 's' (seconds), 'm' (minutes).

Interesting Fields Definition

• Interesting fields have at least 20% presence in the resulting fields of a query.

Field Selection in Splunk

• To make an interesting field a selected field, it can be clicked in the sidebar, and approval must be confirmed in a pop-up.

Field Names Sensitivity

• Field names in Splunk are case sensitive, whereas field values are not.

Argument Differences

• The arguments != and NOT are not the same; they operate differently in queries.

Search Query Behavior

• The query status != 100 returns events where the 'status' field exists but is not equal to 100.
• The query NOT status = 100 retrieves events where the status field does not exist or does not equal 100.

Query Result Comparisons

• The two queries using != and NOT will yield different results.

Search Best Practices

• A good practice recommendation for searches in Splunk is consistent and clear naming conventions.

Default Selected Fields

• In the Search and Reporting app, _time is a default selected field along with 'host', 'source', and 'sourcetype'.

Fields Definition in Splunk

• Fields in Splunk are defined as searchable key/value pairs within event data.

Lookup Types

• Splunk provides four lookup types: file-based, external, KV Store, and geospatial.

Search Result Exclusions

• The search query index=myindex source=c: \mydata.txt NOT error=* returns events where the error field does not exist at all.

Alerts in Splunk

• Splunk alerts are fundamentally based on scheduled or real-time searches.
