Trigger a windows txt file which within its content will have a value of 1 or 0

[beluwi23]

I have been working to create a trigger that will be capable to check the value inside of a windows server file.txt which within its content will have a value of 1 or 0.

Zabbix will read the file and if the read value is = 1, it will do nothing. If not (0) , it will sent an alert and restart the service.

{server.com:vfs.file.regexp[D:\path.txt].last(#3,"0",eq)}> 1

but I when I try to update it says

• Incorrect trigger function "last(#3,"0",eq)" provided in expression. Invalid number of parameters.

Zabbix 4.4.4 version

Any ideas?

Thanks

Hey there

I dont really understand why the "0" and eq in your parameters

Try this

Trigger expression > {host:item.last(#3)}=0 (if last 3 checks = 0 , alert)
Recovery expression > {host:item.last(#3)}>=1

Thanks Guys for your response, I already created the trigger with some Zabbix suggestions and finally it worked for me, just adding those values count(#15,"0",eq)}> 1 and use the vfs.file.contents as expression also the file must be in UTF-8 ANSI.

Wrong... last() works differently with #x. last(#3) is not "last three values" but it is 3rd value from the list...
so if you want to trigger after value has been 0 for 3 times in a row. then use sum(#3)=0 for example.
