I am using Zabbix 2.2.
I have a very specific environment, where I have to generate desired data to file via script, then upload that file to ftp from host and download it to Zabbix server from ftp.
After file is downloaded, I check it with log and vfs.file.regexp items.
I use these items as below:
The line I am parsing looks like below:
C: 8195Mb 5879Mb 2316Mb 28.2
The value I want to extract is 28.2 at the end of file.
The problem I am currently trying to solve is that when I update the file (upload from host to ftp, then download from ftp to Zabbix server), the value does not update.
I was trying only log at start, but I suspect, that log treat the file as real log file and doesn't check the same lines (althought, following the documentation, it should with "all" value), so I added vfs.file.regexp item too.
The log has received a value in past, but it doesn't update.
The vfs.file.regexp hasn't received any value so far.
file.txt has got reuploaded and redownloaded several times and situation doesn't change.
It seems that log reads only new lines in the file, it doesn't check lines already caught if there are any changes.
The zabbix_agentd.log file doesn't report any problem with access to file, nor with regexp construction (it did report "unsupported" for log key, when I had something set up wrong).
I use debug logging level for agent - I haven't found any interesting info about that problem.
I have no idea what I might be doing wrong or what I do not know about how Zabbix is performing these checks.
I see 2 solutions for that: adding more lines to the file instead of making new one or making new files and check them with logrt, but those doesn't satisfy my desires.
Any help is greatly appreciated.
Of course I will provide additional information, if requested - for now I don't know what else might be useful.
