Need help downloading large firewall logs (around 8GB)

[eduardodextil]

I am currently running on OPNsense 22.7.11. My OPNsense box is connected to a high traffic network and generates log files worth 300MB daily. I am trying to retrieve this log files and the end of the month.

When I attempt to download the log files, it downloads an empty blank file.

I have tried editing the php.ini file in the /usr/local/opnsense/service/templates/OPNsense/WebGui directory increasing the memory limit, upload max_size, post_max_size and changing the execution time as indefinite but I have had no luck so far.

Any Ideas on what parameters I could tune to successfully download large files from OPNsense. ?

I have 16GB memory
115GB disk space.

Thank you.

Enable SSH and use scp or sftp.

Also, with that much log traffic being generated, you're probably best off having OPNSense send everything to a remote log server instead of trying to manually download the logs occasionally.

Remote logging might not be an option in this scenario.

Do you have an idea of what might be preventing this download from working ? Is there an hard coded limit set for firewall download apart from those parameters on the php.ini file ?, Are some design constraint or parameter that can be adjusted ?

After removing some of the firewall log files via STFP,  and increasing the limit of the php.ini file the largest size of firewall log files I was able to download was around 600MB.

I also experienced a behavior where the log files are displayed on the web interface instead of a exported log file. This occurrence happened once and I have not been able to reproduce it since.
