Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : Multiple Webservers creating one logfile

[DaiTengu]

I have a dillema. I've got 2 webservers serving the same content (a redundant load balancing system for a high traffic website. One of the coders has mentioned that he'd like to write some logs to a file (hits to a certain page, and some other information) via a PHP script.

The problem is I don't want two seperate log files. I'm thinking of using a NFS Share for the logfile, but I'm worried about slowdowns & possible data loss.

Has anyone had any experience with anything like this? are there better systems out there? I'm not above paying for a solution to help me manage log files either.

Thanks in advance.

If you are using Apache take a look at 'mod_log_sql'.

I have used it in the past and it was very easy to use and will provide you a SQL based logging backend for one or many hosts to share.

It's actually output from a PHP script, I'm trying to stay away from logging it into MySQL as that's even _More_ server intensive than simply writing it to a file.

pardon me while I *bumpity* a bit, I'm still looking for a good solution to this

You can use syslog to log remotely. However, you might need to install a seperate log server on the logging server - I am not sure if you can actually install two syslog servers in a system.

The other option would be to use a distributed filesystem to log the information. As for NFS, you might actually run into issues if you've got a popular site in terms of hits as you might generate write failures on the log and crashing the software writing to the system. I do not know if that was our particular system though, as we've never tried to log things at the same time from application servers.

Take a look for a program called spread. Its used to merge log files.
