A Spike alert matches when the volume of events during a given time period is larger or smaller based on
spike_height than during the previous time period
This would allow you to receive alerts in scenarios such as if there is 3 times spike up based on a ratio value
spike_height in the number of events matching the
filter query, when compared to the previous time window for events
timeframe. Here is an example below:
name: "Spike example alert"
query: "router.status: [500 TO 599]"
In addition, you can also provide a
threshold_cur value that allows you to configure the minimum number of events that must exist in the current window for an alert to be fired.
