Summary: [IGNITE-3769] Visor CMD: improve script execution in
alert command
Key: IGNITE-3785
URL: https://issues.apache.org/jira/browse/IGNITE-3785
Project: Ignite
Issue Type: Task
Components: visor
Reporter: Alexey Kuznetsov
Current logic of executing custom scripts from alert command is not very usable
and need to be improved.
Suppose alert could be in two states: "red" (alert conditions evaluated as
true) and "green".
1) Alert checks condition each t milliseconds (already implemented).
2) If alert detected "red" state then custom script should be executed. If
script is not available - retry with specified rate.
3) After alert detected "red" state it should continue to check condition each
t milliseconds and execute script no more than throttling timeout "-i",
this timeout could be "zero" that means that throttling disabled.
4) After alert detected "green" state then custom scrip executed with special
"green state" flag.
5) When alert executed script it should pass to it how many times it was
evaluated as "red state".
Looks good?
