I think it would be cool if the high-cpu utilization notification emails (configured within the linode manager) included the top 10 processes consuming resources. That way I'd have a rough guess of the root cause (lots of web users, maintenance cronjobs, etc).

Are there any good third-party tools for doing this kinda thing? I reviewed the feature list for Munin, Cacti, and Nagios, but I couldn't tell if any of these support something like this.

Thanks!

Linode doesn't have access to that information, without breaking into your system, so it can't be included in those e-mails. You could probably make Nagios do it, however.

I use monit for this, when something weird happens I get it to dump out ps aux --sort '-rss' and ps aux --sort '-pcpu' so I can at a glance see what's using the most ram and the most cpu.

Wow, monit looks really cool! Seems like a fairly lightweight option with plenty of configuration power. Thanks!

hello,

can you detail the setup you use to get the notification?

thanks.

I use mont's exec option to run basically

ps aux --sort '-rss' | mail root
