[dev] Deduping Functionality in OTRS

Hi All, We use OTRS and nagios combination in our company. Nagios creates tickets whenever there is an alert. If the issue persists for a longer time, Nagios does a couple of checks after a specific period of time and it creates another ticket. My concern here is, a lot of duplicate tickets(similiar) tickets are getting created and this is happening for multiple issues resulting in huge volume of tickets, further increasing the operational load of closing them manually. I would like to know if there is a way to dedupe/update the first ticket itself after doing a recheck (or) is there a way to check if a ticket already exists, if yes udate the same else create a new ticket. Thanking you in Advance. Sharan
