A DevOps engineer wants to determine if the latency their application experiences is growing fester after a new software release a week ago. They have already created two plot lines, A and B, that represent the current latency and the latency a week ago, respectively. How can the engineer use these two plot lines to determine the rate of change in latency?

Correct Answer:C
The correct answer is C. Create a plot C using the formula (A/B-l) and add a scale: 100 function to express the rate of change as a percentage.
To calculate the rate of change in latency, you need to compare the current latency (plot A) with the latency a week ago (plot B). One way to do this is to use the formula (A/B-l), which gives you the ratio of the current latency to the previous latency minus one. This ratio represents how much the current latency has increased or decreased relative to the previous latency. For example, if the current latency is 200 ms and the previous latency is 100 ms, then the ratio is (200/100-l) = 1, which means the current latency is 100% higher than the previous latency1
To express the rate of change as a percentage, you need to multiply the ratio by 100. You can do this by adding a scale: 100 function to the formula. This function scales the values of the plot by a factor of 100. For example, if the ratio is 1, then the scaled value is 100%2 To create a plot C using the formula (A/B-l) and add a scale: 100 function, you need to follow these steps:
✑ Select plot A and plot B from the Metric Finder.
✑ Click on Add Analytics and choose Formula from the list of functions.
✑ In the Formula window, enter (A/B-l) as the formula and click Apply.
✑ Click on Add Analytics again and choose Scale from the list of functions.
✑ In the Scale window, enter 100 as the factor and click Apply.
✑ You should see a new plot C that shows the rate of change in latency as a percentage.

Which of the following chart visualization types are unaffected by changing the time picker on a dashboard? (select all that apply)

Correct Answer:AD
The chart visualization types that are unaffected by changing the time picker on a dashboard are:
✑ Single Value: A single value chart shows the current value of a metric or an expression. It does not depend on the time range of the dashboard, but only on the data resolution and rollup function of the chart1
✑ List: A list chart shows the values of a metric or an expression for each dimension value in a table format. It does not depend on the time range of the dashboard, but only on the data resolution and rollup function of the chart2
Therefore, the correct answer is A and D.
To learn more about how to use different chart visualization types in Splunk Observability Cloud, you can refer to this documentation3.

How is it possible to create a dashboard group that no one else can edit?

Correct Answer:B
According to the web search results, dashboard groups are a feature of Splunk Observability Cloud that allows you to organize and share dashboards with other users in your organization1. You can set permissions for each dashboard group, such as who can view, edit, or manage the dashboards in the group1. To create a dashboard group that no one else can edit, you need to do the following steps:
✑ Create a dashboard group as usual, by selecting Dashboard Group from the
Create menu on the navigation bar, entering a name and description, and adding dashboards to the group1.
✑ Select Alert settings from the Dashboard actions menu () on the top right corner of the dashboard group. This will open a dialog box where you can configure the permissions for the dashboard group1.
✑ Under Write access, select Only me. This will restrict the write access to the
dashboard group to yourself only. No one else will be able to edit or delete the dashboards in the group1.
✑ Click Save. This will create a dashboard group that no one else can edit.

Which of the following are correct ports for the specified components in the OpenTelemetry Collector?

Correct Answer:D
The correct answer is D. gRPC (4317), SignalFx (9080), Fluentd (8006). According to the web search results, these are the default ports for the corresponding components in the OpenTelemetry Collector. You can verify this by looking at the table of
exposed ports and endpoints in the first result1. You can also see the agent and gateway configuration files in the same result for more details.

What information is needed to create a detector?

Correct Answer:C
According to the Splunk Observability Cloud documentation1, to create a detector, you need the following information:
✑ Alert Signal: This is the metric or dimension that you want to monitor and alert on.
You can select a signal from a chart or a dashboard, or enter a SignalFlow query to define the signal.
✑ Alert Condition: This is the criteria that determines when an alert is triggered or cleared. You can choose from various built-in alert conditions, such as static threshold, dynamic threshold, outlier, missing data, and so on. You can also specify the severity level and the trigger sensitivity for each alert condition.
✑ Alert Settings: This is the configuration that determines how the detector behaves
and interacts with other detectors. You can set the detector name, description, resolution, run lag, max delay, and detector rules. You can also enable or disable the detector, and mute or unmute the alerts.
✑ Alert Message: This is the text that appears in the alert notification and event feed.
You can customize the alert message with variables, such as signal name, value, condition, severity, and so on. You can also use markdown formatting to enhance the message appearance.
✑ Alert Recipients: This is the list of destinations where you want to send the alert
notifications. You can choose from various channels, such as email, Slack, PagerDuty, webhook, and so on. You can also specify the notification frequency and suppression settings.
