Compare the today date with a date inside a txt file (Windows Server)

[GDT]

I need to create a check that compares the today date with a date string inside a txt file for a bunch of Windows Servers, this is an example of the TXT file, I need to compare the date in the line which starts with "Expires" :

[Main]
ComputerID=xxxxx
HardwareID=xxxxx

[Product.Remote]
Edition=xxxxx
Users=xxx

[Support.Remote]
Expires=2023/02/27 00:00:00​

[Other data]

Any idea?

Thank you.

Create an item of the zabbix_agent type and the vfs.file.contents key - gets the contents of the file.
There are two steps in preprocessing:
1) regexp ^Expires=(.*)$ and output /1
2) JavaScript - convert date from string to unixtime (like (new Date("2023/02/27 00:00:00").getTime()/1000) ) and compare with now.

Ok, I grabbed the file with vfs.file.contents key. It's not clear to me how to set up the preprocessing steps: shoud I use "Regular Expression" for first step? And how to set up the javascript?

[GDT]

I did some progress: I was able to estract date with this key expression: vfs.file.regexp["c:\program files (x86)\tsplus\userdesktop\files\license.lic","^Expi res=(.*)",,,,\1]
Now I need to convert to epoch (UnixTime) but I don't know how to do it.

Then I need an alert which triggers warning when the extracted date is under 30 days ad turns critical when 7 days. Do I need a trigger? How can I set it up?

More progress: I got the extrated date in UnixTime format now I need the compare check.
Please help me!

I meant “Regular Expression” https://www.zabbix.com/documentation.../preprocessing But how did you do it is also fine
JavaScript - https://www.zabbix.com/documentation...ing/javascript

The idea was to convert the string to unixtime in the preprocessing step using JS and calculate the difference from now there. Then the item will store exactly the date difference. And based on this difference, you can create simple triggers (with various severity) that respond to raising thresholds.
