Create a metric alert

Metric monitors analyze continuous streams of data. When collecting metrics through Kloudfuse or APIs, you can configure alerts to trigger on specified conditions.

To create a metric alert, complete these tasks:

• Begin defining a metric alert
• Choose the detection method
• Pick metric
• Set condition
• Add details
• Add contacts
• Create rule

Start defining a metric alert

1. In the Alerts interface, click .
2. In the initial interface for creating alerts, Kloudfuse guides you to select the appropriate alert type.

Choose Metric.

3. The Create Metric Alert interface appears.

Choose the detection method

Metric alerts have these detection options:

• Threshold alert select
• Change alert select
• Outliers alert select
• Anomaly detection select
• Forecast Alert select

Pick metric

1. Next to the first query, marked by , click the text field to select a metric from the drop-down.

2. The chart of the metric over the time period appears.

You can proceed with these optional configurations:

• Work with filters
• Work with aggregations
• Work with functions
• Work with queries
• Work with formulas
• Change step size

Work with filters

1. To add a new filter, select a label and add it to the metric view.

Next to the tag, click the (Add) icon.

2. In the expanded view, click the first (Select) option, and choose the new label from the drop-down.
3. Choose the comparison operator:

• =~ Regex expression equal
  • !~ Regex expression not equal
  • != Not equal
  • = Equal (default)

4. Finally, click the second (Select) option, and choose the label value from the drop-down.

5. To add another filter, click the (Add) icon, and specify the new label.

6. To remove a filter, click the (Delete) icon that corresponds to the label/value pair that you plan to remove.

7. The filter no longer appears on the page.

Work with aggregations

1. In the aggregation section, click avg, and select another aggregation calculation from the drop-down.
2. The chart changes to show the newly selected aggregation of results.
3. To aggregate over another dimension, in the metrics selector specify the aggregation by clicking Select, and choosing another metric option from the drop-down.
4. To remove the aggregation, in the aggregation section click the (Remove) icon.

Work with functions

1. To add a new function to the graph, click the (Sigma) icon at the end of the query specification.
2. In the drop-down, either search for a function name, or select an existing function category, and then pick the function name.
3. Configure the parameters of the function, if any.
4. To remove a function, click (Remove function) icon, next to the function you want to drop.

Work with queries

1. To add a query, click (Add Query).
2. Notice that a new query (B) appears under query (A), and it is a duplicate.
3. Change the selected filter in query (B).
4. To remove one of the queries, click the (Remove) icon that corresponds to the query you plan to remove.

Work with formulas

Add formula

You can combine metrics over facets or labels into formulas, to get additional insights.

1. To add a formula, click (Add Formula).
2. The empty formula option appears in interface.
3. Type the formula in the text box next to the label.
4. To remove a formula, click the (Delete) icon that corresponds to the formula you plan to remove.
5. The formula is no longer in the interface.

Change step size

1. Click the Steps option of the metric.
2. Notice the default step size, and change it to what you require.
3. Observe how the graph for the metric changes with new step size.
4. If you click the (Delete) icon, the step size reverts to the default.

Set condition

There are some differences in the process of setting the alerting condition, depending on the detection method.

1. Define the condition.

  • Anomaly Detection Alert
  • Forecast alert

1. From the first drop-down, select the condition function: Mean, Min, Max, Sum, Count, or Last (default).

2. From the second drop-down, select the evaluated query ( Query (a), Query (b), and so on) or formula ( Formula (1), Formula (2), and so on).

3. From the third drop-down, select the comparison operator: above (default), below, equal to, not equal to, above or equal to, or below or equal to.

4. [Optional] In the text box, specify the unit of the measurement.

5. In the fourth (last) drop-down, specify the time interval: 5 minutes, 10 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, 1 day, 2 days, 1 week, or 1 month.

6. Expand the Configure no data and error handling option.

No data What to do when data is missing.

In the first drop-down, select one of the options: Alerting, No data, or OK (default).

Error handling What to do when there is an execution error, or a timeout.

In the second drop-down, select one of the options: Alerting, OK, or Error (default).
