Steps to reproduce:
- Create a trigger prototype based on 2 discovered values
- The trigger get triggered
- Leave the problem as is for a few months
- The value cache gets full because ALL the values since the trigger is triggered are kept in the value cache
Trigger
Name: Free disk space is less than 2GiB and 20% on volume {#FSNAME}
Expression: {Template OS Linux:vfs.fs.size[{#FSNAME},free].last(0)}<2147483648 and {Template OS Linux:vfs.fs.size[{#FSNAME},pfree].last(0)}<20
Expected:
Value cache does not get full.
