Hi guys, I am running some sites on a VPS, and I have been having compaints that people have been unable to access my site, and just get page not found. Is there any way that I check to see if my site was actually down, or if it may have been an issue their end? I haven't had any problems at all with it. I've got WHM and VZPP. Thanks in advance!
First of all, check the uptime of your VPS. If it is less (like a couple of hours or days), that means the VPS has recently rebooted and it may be a frequent occurrence. In that case, check with your hosting provider about the issue. Next, check your system logs for clues. The dmesg command, /var/log/messages log file and other logs specific to your web server or application should give you some useful details. Maybe you're getting so much traffic that the server stops responding. Maybe you're under some sort of attack. And maybe, it's just a wrong configuration. Install sysstat. This allows you to check the recent history of system load, memory and cpu usage etc.
