Is there anything that I can use to monitor the overall systems of my Linux site? I'm looking for an app of some kind that I can run on my win7 desktop and check on processes, memory, mysql, disk space, etc.

I have a site that keeps crashing and I suspect the php code. I'd like to be able to monitor the site services, etc.

Thanks

Hi Ralph,

You might want to try Cacti (http://www.cacti.net). It's an Open Source Web-based monitoring tool based on RRD. So that you may to access it through the web browser regardless the Operating System.

Thanks for that link. I have to say after reading how to install it I was completely lost. Looks like a nice package but I'm not an Linux Admin and I can see there is a lot going on just to install it and then a lot to figure out to configure it. I think it would be perfect for a Linux geek but that's not me.

Ah, I am sorry to hear that. I haven't found any monitoring tool for Linux that can be installed in few click as it is for Windows. I used some of monitoring tools for Linux, and they were typically installed in the same way. FYI, as alternatives to Cacti, you might want to review:

- Zabbix (http://www.zabbix.com/)
- Nagios (http://www.nagios.org/)
- Zenoss (http://www.zenoss.com/)
- OpenNMS (http://www.opennms.org/)
- Ganglia (http://ganglia.sourceforge.net/)
- GroundWork Open Source (http://www.groundworkopensource.com/)

Anyway, good luck for you Ralph!

I ended up going with a few website monitoring services that can monitor HTTP, DNS, Ping, MySQL, POP3 and SMTP. There are called external monitoring. One of them also provides for internal monitoring which is really what I was looking for: CPU usage, RAM usage, etc.

I'm wondering if I need to monitor all three of HTTP, DNS and Ping? I'm not sure I know what the difference is in regards to pinging my site vs checking its HTTP vs doing a DNS check. Do I need all three monitored? My goal is two fold: (1) provide a history of up time and (2) monitor the internals to make sure the Linux server isn't being over loaded or running out of ram, etc.

Thanks

All goes well with the applications manager. Has a simple user interface that offers the best visibility of how well the servers and applications running. E-mail alerts and notifications have been very useful.
