-----------------------------------
Summary: Create a new alert type that is based on timeseries
metrics
Key: AMBARI-15766
URL: https://issues.apache.org/jira/browse/AMBARI-15766
Project: Ambari
Issue Type: Task
Components: alerts, ambari-metrics
Affects Versions: 2.4.0
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Priority: Critical
Fix For: 2.4.0
There are a few requirements around creating alerts based on the time-series
data stored in AMS. They fall in the the general category of:
identify a metrics (name of the metrics, app name)
identify a window (e.g. last 10 minutes, last 1 day)
get the data points
add them up, or
compute average, or
compute standard deviations, or
...
compare the value to a threshold
emit an alert if needed (WARN, CRITICAL, etc)
We should also allow for alerts based on multiple metrics but there is no ask
for such a capability. Just something to keep in mind while designing.
It seems general enough that we should define an alert type that can be
instantiated by services to define specific alerts. Users can add additional
alerts if they so choose.
