Hi Vasiliy,
After a script is executed on the first alert I would follow these steps
to manage the frequency:
- execute the script only after alert's condition goes below set
watermark and then hits the watermark again.
- if the condition is fluctuating (goes up and down over the watermark)
too frequent (couple of times in 2 or so minutes) then I would avoid
calling the script to reduce possible spam generation.

Hello.
I started work on issue "Visor CMD: Add ability to attach custom scripts to
alerts" https://issues.apache.org/jira/browse/IGNITE-29
<https://issues.apache.org/jira/browse/IGNITE-2856>19
and plan to add parameter -s=”script path” to configure path of script to
execute on generation of alert.
I notice that default frequency of alert generation is 15 min. I think that
time period is very large and suggest to change it to 1 min.
Also I faced with choice of alert generation frequency and suggest three
variants:
1. Execute script only once on first generation of alert.
2. Execute script after some cooldown period from previous execution (f.e.
after 5 min from).
3. Execute script after specified count of alert generations from previous
execution (f.e every second or third or ...).
