/**
|
||
|
|
* Re-key open automated network tickets after #116.
|
||
|
|
*
|
||
|
|
* Network tickets used to hash on host alone, so every network alert for a
|
||
|
|
* host shared one ticket. They now hash on host + the problem's heading (see
|
||
|
|
* helpers/TicketHash.php). Without this script, each open network ticket
|
||
|
|
* keeps its old hash and its next alert opens a duplicate instead of
|
||
|
|
* updating it. Run once after deploying #116:
|
||
|
|
*
|
||
|
|
* php scripts/rehash_network_tickets.php --dry-run # report only
|
||
|
|
* php scripts/rehash_network_tickets.php
|
||
|
|
*
|
||
|
|
* Closed tickets keep their old hash on purpose: they stop catching
|
||
|
|
* unrelated alerts. A ticket whose new hash already belongs to another ticket
|
||
|
|
* is skipped and reported (resolve it by hand). Safe to re-run.
