How can get current date to check file exist or not by zabbix

[bab]

I have a job on my server that can create dump files everyday with current date of day such as follow name in /home path
dump-20230212.tar.gz
It will create this dump file every day . Now I want to create an item that can check the file has created or not . in some forums they said at the first step we need to create a discovery rule type script that returns [{"{#DATE}":"YYMMDD"}] (with YYYY,MM,DD calculated in javascript from the current date) . Would you please help me how can do it ?

I know first step we have to get current date and in the next step I think have to use vfs.dir.count

Just use <max_age> prarmeter of vfs.dir.count

Thanks. But for example today 20230215 it generates dump-20200215.tar.gz and now it should checks dump-20200215.tar.gz exist or not
for tmorrow 20230216 it should checks dump-20200215.tar.gz exist or not actually at the first step I want to get current date . If we can get current date with that method also we can use it for other things.

You can check once a day, on a schedule, if there is a fresh file with a name that fits a regular expression. If the file is yesterday, it will not be counted due to age.

As my filename is like dump20230215.tar.gz in /home directory
Does it correct :

vfs.dir.count[/home,dump,,,,,1000000000,,,86400,]

[Semiadmin]

maybe vfs.dir.count[/home,"dump\d+\.tar\.gz",,,,,,,,1d]

maybe vfs.dir.count[/home,"dump\d+\.tar\.gz",,,,,,,,1d]

Does \d in dump\d relates to 1d ?

Does \d in dump\d relates to 1d ?

no \d in regex means "any digit" and + after that means "one or more of previous"... making it "dump followed by as many digits as there is"
