Soooo do I leave it at approx 6 and watch the intermittant spikes come and go? Do I got for 8 or more after it exceeds an effective load

So you might consider making your script email you the output of `top`
when the load gets high. It sounds like you've got some job that's
running every half hour or so that's driving the load up.

Heh. Actually, on Linux, `top` may not be what you want. It appears to
ONLY support an interactive mode (complete with all the terminal-handling metacharacters in its output). On BSD, if you pipe the output of top
into a program, it does one interation and omits the terminal stuff, so
you can pipe it into `mail` or something.

However, on Linux, you can run `ps` in a way that will show you the top consumers of CPU time:

ps -Ao user,uid,comm,pid,pcpu --sort=-pcpu | head -20

If you decide that you want to include that in an email, you can
include some explanatory text via something like:

load=$(awk '{print $1}' /proc/loadavg)
if [ $(expr $load '>' 8) -eq 1 ]; then
(echo "Load average exceeds threshold: $load";
ps -Ao user,uid,comm,pid,pcpu --sort=-pcpu | head -20) |
mail -s "Load average alert" user@where.ever
fi

Note the '()' around `echo` and `ps`; this invokes them in a subshell.
The output of the entire subshell is then piped to `mail`.

Good call on top, never looked at it for that purpose before. Looks like the suspect screen saver is probably the culprit, m6502. Its been modified for screen blanking only we'll see what happens.

It feels like that at times doesn't it. In dem good ol' days I used to read all
smaller boards and TLP backwards, until you got tired of reading... if you're on top of the message reading it works well. But in these days of using "The Reader" or whatever else you're using it seems a lot easier to keep reading it forwards.

You could use `ps` like this;

ps axo pid,%cpu,cmd --sort=%cpu | tail -5 | tac


What does this do?
"ps axo pid,%cpu,cmd --sort=%cpu" just lists all running processes
displaying just the PID, the %CPU usage and the command itself
"| tail -5" takes the output of the above and shows just the last 5
lines of it - anything more would likely be too much...
"| tac" takes the output of the above and reverses it.

This will produce a list of the top 5 processes using the cpu, with the
highest at the top in a descending order.

Hope this helps =)

Using `tac` is a clever trick, but if you prepend a '-' to the sort
character, it'll reverse the sort order so that processes are listed
in descending order. Then you can use `head` (or the more authentic
`sed 10q` and also have the header).

This is true, but I wanted it without the header so leaving it ascending and then grab the last 5 and then reversing them saved a whole bunch of sed/awk/jiggery-pokery imo.

I've heard of OpenNebula - not exactly sure what it does. I know of it because I get spam every now and again.

I'm playing with ansible and OpenShift... My goal is to deploy VMs with ansible, and then automate the install of Openshift in those VMs. (I want to automate it, so when it expires in 60 days, I can rebuild it...)

Hopefully achieving above I'll learn more about both products...

Chuckle, if you take them in the correct order from the start, you can just feed it through tail. The length of the top output is fixed, just tail 20 I think it is off hand and you've got all the results. I actually ended up using tail to remove the header, and then head to limit the result to top 10 :)

OpenNebula is another hypervisor platform like proxmox, opensource. It looks pretty nice, but it's not as easy to do stuff in, but it seems to be more powerful too.

I'm playing with ansible and OpenShift... My goal is to deploy VMs with ansible, and then automate the install of Openshift in those VMs. (I

That sounds like fun, I haven't really done anything in ansible myself much
yet but I use it at work running a bunch of playbooks that someone else made
to build our systems. It's pretty nice.

Hopefully achieving above I'll learn more about both products...
