What type of monitoring do you do for your VPS?
Hello.
I'm using a LEB to store all my backups from a larger ManagedVPS. I am not proficient with sysadmin tasks and this LEB helped me to learn stuff. I wrote a simple bash script to delete files older than 14 days. May I know what type of monitoring do you do on your machines to keep it healthy and secure? What important logs do I need to look at? What commands should I use?
I have another LEB I don't still use for production, I'm just using it to learn things as well. I might be able to apply your suggestions on this box.
Any help is appreciated.

Linux isn't like Windows.
In the sense that you don't need any clean/maintenance generally.
Commonly, the only things increasing are the stuff at /var/log and sometimes /tmp
Sometimes another cache folders depending on your applications.
Anyway, you can have all this garbage and most likely everything will work as always.
Is better if you focus on keeping your web applications clean of useless files if the disk space can become an issue AND your databases optimized.
If you use duplicity for backups, you can instruct duplicity to delete old backups with an option.
munin is the shit.
+1, duplicity is awesome!
I have made the experience that uninstalling apps often still leaves the config files or so on the harddisk.
I use logcheck to keep an eye on log files. It runs hourly and compares the log files to a list of regular expressions. Anything that does/doesn't match is sent to you in an email. It comes with a bunch of files that weed out most of the mundane stuff and I added a few files of my own.
Well, this might be a little over the top, but here we go.
I'm currently using a combination of services.
For monitoring PHP/MySQL performance, I use NewRelic. I'm using a paid version for free, because GNAX are awesome, although the Free version should be fine anyway.
Loads of graphs, and 'just works'. No fiddling to get things up and running. Also, incredibly detailed.
For uptime monitoring, I use UptimeRobot.
Not the most glamorous service, but it certainly gets the job done.
For monitoring multiple VPS' disk space and bandwidth, I use this extension for Google Chrome.
The 'disable monitoring' feature works wonders, especially when you have an AlienVPS box. I've set it to check ever 5 minutes, and it seems to be relatively accurate.
Edit: Oh, keeping it secure? apt-get upgrade works for me.
I'm using it to. It's great. Recommended++
Yes, but that doesn't affect performance
Btw, according to the text of the first post, he isn't asking for uptime monitoring, but performance monitoring, I think
munin+a ping script I found on LET.
@gsrdgrdghd
apt-get purge packageand manually remove the config files, if any.Sadly for me it's only pingdom.
@Taylor why pay for pingdom when you can have something more awesome like munin for free?
monitor.us is good for VPS monitoring too and its free!

Thank you everyone for your input. I'll look at each one of them and see how I can use them.
If you were confused with my first post, I was actually asking for any security measures you perform on a regular basis (daily, weekly or monthly) for your VPS. e.g. checking for malicious files or attacks
Multiple instances of OpenStatus, along with a small handful of custom notification scripts.
Pingdom, @NickM 's www.checkmyservers.com and OpenStatus, plus munin.
