Monitor file creation in Zabbix. How to make it swear that the file is not created?

Question

Monitoring

Good health to all.
I haven’t held Zabbix in my hands for a long time and haven’t set it up like this for 4 years. I don’t remember anything anymore.
The task is this:
There are servers that make backups with scripts.
You need to teach Zabbix to monitor the folder for new files, and if a file is not created, immediately swear with an alarm.

Answer 1

vfs.file.exists must be the exact file name. If it is not known in advance, but it is necessary, for example, to track exactly the frequency of creating new files, then it is easier to monitor the modification time of the parent folder with the vfs.file.time (folder_name) parameter

Answer 2

When something is forgotten, then you need to open and read the documentation:
See the description of vfs.file.exists . It?
