Passive Checks check interval

Hello,

I’m putting data from NAgios into MySQL database, The proble is that database grows 168000 records per day.
Is there any way to change frequency of this? Now I have 140 passive checks every minute. Can I change this time?
Or maybe put data into database only if they change.
I think there is a way to check if data in output are changed but I don’t remember how it works.

Any suggestions?

Try disabling volatile optin in service definitions

I have no ‘is_volatile’ option enabled at all.

Then check the script or program that sends passive checks, and configure it not to send if there is no state change.
