Logrt for monitoring files with data in name

[Konrad_22]

Hi guys,
My problem is that i would like to monitor few files in one directory, <D:\logs>, every name starts with data like <2020-11-19_app.log> and app creates new file everyday.
Im trying to use logrt but i cant solve this problem.

im trying with something like this, i checked regex101 and it should find this file,
logrt["D:/.*.log","error"]

Please help me and thank you

Do you have any idea how i could check logs for errors, warns etc but not with .*.log? any idea how i could connect data with file name?
for example today i would like to scan only files which starts with 2020-11-19

logrt["D:\\\d{4}-\d{2}-\d{2}_app\.log","error"]

I still have problem with that file, the string with localisation looks ok but i get my data only when file localisation is not set as regex

any solutions?

[Konrad_22]

Could someone tell me where the regex should start in the file path? for example file name
logrt["D:\app\zabbix\logs\\\d{4}-\d{2}-\d{2}_app\.log","error"]
is ok? because zabbix cant reach this localisation

I have this version of the expression that works:

logrt["D:\app\zabbix\logs\^\d{4}-\d{2}-\d{2}_app\.log$","error"]

in this expression, the regular expression describes only the file name.

sure but why it cant find any errors? i have same problem zabbix find files .*.log but cant find errors, warnings etc

logrt["D:\\app\\zabbix\\logs\\\d{4}-\d{2}-\d{2}_app\.log","error"] missing couple of \-s, I think.

Just out of curiosity
Added a file to a box, I have here .. C:\apps\logs\2020-11-20_app.log
added an item

logrt["C:\app\logs\^\d{4}-\d{2}-\d{2}_app\.log$","error"]

It became "Not supported": Cannot compile a regular expression describing filename pattern: PCRE does not support \L, \l, \N{name}, \U, or \u
changed to

logrt["C:\\app\\logs\\^\d{4}-\d{2}-\d{2}_app\.log$","error"]

Became supported...
Using 4.4.10 here...

It still fails to find any "error"-s I write in there, but that's another story...

Good question.. I found an aswer from agent logfile
1340:20201120:142105.961 there are no recently modified files matching "app\\logs\\^\d{4}-\d{2}-\d{2}_app\.log$" in "C:"

I had made a mistake.. one missing s in path..
After that also the version what Hamardaban suggested works, with single \-s
EDIT: point being... look int agent logfile, maybe you find something useful there..
