Threshold configuration for Route 53 Health Check
Add a new threshold configuration for Route 53 Health Check monitor.
When a new Health Check monitor is added, it is associated with a default threshold profile. This profile doesn’t contain any pre populated thresholds attached with it. You can either edit the default threshold profile or create yourself a new one.
To create a new threshold profile for your Route 53 Health Check monitor follow the below mentioned steps. To add users and to customize alert settings visit our User and Alert management page.
- Configuration Profiles > Threshold and Availability.
- Click Add Threshold and Availability in Threshold and Availability screen.
- Specify the following details:
- Monitor Type: Select Route 53 Health Check from the drop down list.
- Display Name: Provide a label for identification purpose.
The performance counters supported for the monitor will be shown below. Configure values in the fields provided, these values will act as your thresholds. When a threshold gets breached, your monitor status will change and alerts will be triggered out via the configured notification channel.
Once you are done configuring threshold values, you can go ahead and save the profile. Once done, the newly created threshold profile will be listed in the Threshold and Availability screen.
Advanced threshold settings (Strategy)
You can also validate the threshold breach, by selecting relevant strategies and applying various conditions for any performance counter. For example, let's take a scenario where you require the Child Healthy Healthy Count to stay above 85%. However, there might be instances where an end-point is not healthy due to a network latency. In such cases, you need not be alerted immediately and you can set up a threshold strategy where you will only be alerted when there is a failure for more than two or three continuos checks.
Poll count serves as the default strategy to validate the threshold breach. You can validate threshold breach by applying multiple conditions (=,>, <, >=, <=) on your specified threshold strategy. The monitor’s status changes to ”Trouble” when the condition applied to any of the below threshold strategies hold true:
- Threshold condition validated during the poll count (number of polls): Monitor’s status changes to trouble when the condition applied to the threshold value is continuously validated for the specified “Poll count”.
- Average value during poll count (number of polls): Monitor’s status changes to trouble, when the average of the attribute values, for the number of polls configured, continuously justifies the condition applied on the threshold value.
- Condition validated during time duration (in minutes): When the specified condition applied on the threshold value is continuously validated, for all the polls, during the time duration configured, monitor’s status changes to trouble.
- Average value during time duration (in minutes): Monitor’s status changes to trouble, when the average of the attribute values, for the time duration configured, continuously justifies the condition applied on the threshold value.
Multiple poll check strategy will not be applied by default. During the conditions where no strategy could be applied, the threshold breach will be validated for a single poll alone.
To make sure the condition applied on the strategy “Strategy-3: Time duration or Strategy-4: Average value during time duration” for threshold breach detection works as intended, you must ensure that you specify a time duration which is at least twice the applied check frequency for that monitor.
