How to create a trigger for numeric float date in a file

[vershooter]

Hi,

I am a newbie in zabbix,

I created a script in linux and it will create a file that has a value on it. The data in a file has only one value / number .


For example.

/home/testuser/textfile.txt

If you cat the textfle.txt the output is 50

the data in textfile.txt is 50.

Then I want to create a zabbix alert if the data in that text file will be greater than 100 , zabbix will give me alert.

Is this possible?

Create Zabbix agent item.
Use fs.file.contents[/home/testuser/textfile.txt,] as key.
Type could be Numeric float or unsigned.


Then create trigger with this expression ("Test" is hostname in my case):
{Test:vfs.file.contents[/home/testuser/textfile.txt,].last()}>100

Which user has been used to run zabbix agent?
Does that user has permission to read the file?

[vershooter]

zabbix iser, as checked on ps -ef | grep zabbix

Yes I change the the owner to zabbix and I also change the permission to rwx in user, group others

Hi All,

Can anyone help me. Thanks

[tikkami]

Must be still some issue with file/folder permissions. Try e.g. /tmp.

Still same,

I tried to put the file in /tmp


-rwxrwxrwx this is the permission of the file.

Are you using SELinux, AppArmor, or some other security mechanism on the client where the agent is running?

What version of Zabbix agent are you using? Are you using a version of the agent that supports vfs.file.contents[]?
