Setting Up KloudMate Alarms

kloudmate lets users create and configure alarms for events that are critical to their application by setting up alarms on kloudmate, users can keep abreast of times when certain metrics are above or below a set of pre defined thresholds and take necessary actions as soon as possible these alarms are entirely customizable and can be configured for any aws service available in kloudmate inventory, using metrics associated with them for example, the following are some of the lambda function metrics for which users can set up alarms memory used coldstart count coldstart duration getting started users can create, delete, and edit their alarms in the alarms section click on the bell icon and navigate to the alarms section from home the alarms section will display a list of existing alarms (if any) you can view, pause, delete, or edit any of these alarms using their corresponding more options icon to learn about the key concepts of kloudmate alarms, see understanding kloudmate alarms creating a new alarm to create a new alarm, click on the create alarm button located at the top right corner of the alarms screen it will open the create alarm page which lets you add queries and expressions you can create and set multiple queries and expressions using the add query and add expression buttons you can also replicate a query or expression by clicking on the copy icon available at the top right corner of each query or expression for each query and expression, there will be a unique alphabetical notation associated with it, such as a, b, c, and so on step 1 setup query conditions and evaluation expressions choose opentelemetry or kloudmate as the data source in the first dropdown menu 1 1 setting up query conditions for aws set a time duration for which you want the data to be fetched, either use the dropdown menu or use the custom field (in case of custom time, enter the time duration in seconds) select the region from its corresponding dropdown menu it specifies the aws region of the service you want to create an alarm for select the namespace from its corresponding dropdown menu the namespace is the service you want to create an alarm for select the metric from its corresponding dropdown menu it specifies the metric associated with the selected namespace that you want to monitor select the statistic from its corresponding dropdown menu it is the statistical function you want to use to calculate data points you can use dimensions to configure the alarm for group resources of the selected namespace for example, for ec2, you can choose an autoscaling group name, image id, instance type, and more in the dimensions dropdown menu to configure the alarm for all the instances in the same dimension click on the run query button 1 2 setting up query conditions for opentelemetry select the data set that you want to retrieve and work with, from your opentelemetry data source under the metric to aggregate option , select the metric it specifies the metric associated with the selected data set that you want to monitor for the group by option, enter the attributes to group the data points you can add filters to narrow down the retrieved data points opentelemetry users can use prometheus query language to retrieve data and use it to set alarms 1 3 use time range expressions for custom time alarm query time ranges support the following operators (subtract time) same units and keywords as dashboards refer to time range expressions and settings examples now , now 5m 1 4 setting up evaluation expressions in evaluating expressions, the value of a query condition or an expression that has already been configured can be passed as parameters using their alphabetical notation such as a, b, c, and so on note that an expression can be passed as a parameter only in case of multiple expressions for expression, choose from math expression, reduce, or condition expression options in the case of math expression, enter the expression that you want to apply to the value of a query/expression in the given text field for example $a+1, $a<$b, $a && $c for more information, see writing expressions for kloudmate alarms in the case of reduce expression , use the first dropdown menu to choose the function you want to use to aggregate the values of a query/expression into a single value and select the desired query/expression from the input dropdown menu note the following are some of the available functions to choose from mean() get average value max() get maximum value min() get minimum value sum() get the sum of all value last() get the last value count() get the total number of value in the case of condition expression, select the function and a query/expression from their respective dropdown menus select the desired condition from its corresponding dropdown menu and provide a value against which the condition will be evaluated you can add multiple conditions in a condition expression and choose how they work together using logical operators such as or & and click on the run queries button to avoid the 'nodata' issue when using multiple queries in a single alarm, use the operator 'ifnull' to assign a default value read more in writing expressions for kloudmate alarms step 2 configure the alarm evaluation settings for alarm condition, select the query or the expression to trigger the alarm in the evaluate every (seconds) field , define how frequently the alarm condition should be evaluated in the evaluate for (seconds) field , define how long the alarm condition should be evaluated and found to be true before the alarm gets triggered in the alert state dropdown menus , select the alarm behavior if the query results in no data or in an error click on the preview alarms button to run the query instantaneously and check the result step 3 add alarm details enter the alarm name and a description of the alarm step 4 add notification tags add tags to the alarm you can configure a notification policy to send notifications to a particular channel when the alarm is triggered with matching tags step 5 save the alarm click on the save button to save the alarm, or click on the save & close button to save the alarm and go back to the alarms section related resources understanding kloudmate alarms writing expressions for kloudmate alarms
