What are tools you would recommend for analyzing VPS performance? Specifically I run several WordPress blogs on a VPS and would like to find some tools to help me find issues worth looking into (so I can address them).
I use New Relic for getting some data on where to focus some attention on our Rails applications and find it very useful.
I have a feeling there might be issues with memory use. I would love to see something that showed memory use over time so I could see what my memory use looks like. I am considering upgrading the VPS and this would be one useful piece of data.
“top” is always a good place to start in the terminal.
but http://scoutapp.com/ is a really good monitoring app, and easy to implement on vps servers
Try Munin, is a great monitoring app with a web interface, http://munin-monitoring.org/
cloudstats.me
works free for three VPS
New Relic has a free server monitoring service that will show you CPU, memory, network I/O, disk I/O, and disk capacity, as well as a process list a la
top.
