I'm pretty new to Linux and I'm looking for a monitoring tool that has a web front end. Specifically looking for stats on the following:

  • Storage space, Used/Free
  • CPU Activity
  • CPU Temps
  • RAM Usage

Everything I would expect from server monitoring software, having the ability to send emails based on things like high CPU temps would be a bonus.

Ideally I'd like to find something free & open source but will pay if something is worth it.

Does anyone have any recommendations?

Thanks

Steve

I like munin - pretty much with just installation (munin-node on each host and munin "master" on the collecting and graphing server), and pointing to the hosts, I got full detail on hardware sensors, cpu, disks, memory, interrupts, lots more. It has a web interface for viewing but not as far as I know for configuring.

Cacti is a well-established monitoring tool with a full web ui for configuration and management. It is good at ping and snmp for network management of hosts; I have not found it as easy to get the kind of info you are asking for from it.

If you want to do a full evaluation, Nagios is another widely used package with a free option, but I have no info on it.

You can use Monitorix , the list of feature can be found here.

Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible. It has been created to be used under production Linux/UNIX servers, but due to its simplicity and small size can be used on embedded devices as well.

To install it on Ubuntu , add the following line to your sources.list:

deb http://apt.izzysoft.de/ubuntu generic universe

Add the gpg key:

wget http://apt.izzysoft.de/izzysoft.asc
apt-key add izzysoft.asc

Install it:

apt-get update
apt-get install monitorix

Open this url: http://localhost:8080/monitorix/ on your browser.

To get alerted through sms or mails you can use nagios

https://www.icinga.com/, along with deployment via Chef or Puppet. FYI, there is no "best". But Icinga is very good. You can find more on Wikipedia.

You do need to have someone to catch the alerts and interpret the output.
