bug in vfs.dir.count?

[rsokoll]

Hi,

I want to monitor the number of entries (files and folders) in /etc. To do so, I have an item with that key: vfs.dir.count[/etc,,^\..+\.sw?$,,,0,,,,] The regex ^\..+\.sw?$ should prevent swap files generated by vim from getting counted.
However:

root@zabbix-server:/etc# zabbix_get -s localhost -k 'vfs.dir.count[/etc,,^\..+\.sw?$,,,0,,,,]'
250
root@zabbix-server:/etc# ls -A1 | wc -l
250
root@zabbix-server:/etc# touch .test.swp
root@zabbix-server:/etc# ls -A1 | wc -l
251
root@zabbix-server:/etc# zabbix_get -s localhost -k 'vfs.dir.count[/etc,,^\..+\.sw?$,,,0,,,,]'
251

Do I misunderstand the documentation at https://www.zabbix.com/documentation...#vfs.dir.count - or is it really a bug?
Both server and agent2 have version 7.0.16

Your regex (part of it) is invalid for your purpose: "sw?$" matches strings that end with "s" or "sw" (does not match "swp"). Question mark means "zero or one of the previous character".

I'm not familiar with vi swap file possible namings, but you maybe meant "sw.?$" (matches sw, swp, swa, ...)

Oh my. Yes, you are correct. It was the missing "." in the regex.
