Study Notes

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.
