Xen users - Feb 2008 - xen tools for checking performance

Hi all



what kind of tools i can use for checking the performance of xen guests. In
terms of memory, cpu and other resources so that i can decide on how many
guest i can run on my server( i can size my server)



thanks

I use traditional SNMP with rrdtools. I create my own scripts in Perl and PHP 
but a good option is Cacti.

I using everything combined. Actually I create a network traffic graphic, CPU 
utilization (With User, Nice, System, I/O Wait, SoftIRQ and IRQ Wait), Memory 
(Process, Buffer, Cached, Swap) and disk space per partition. I need to 
create more two graphs, Disk I/O and Temperature (this last only on dom0). 

SNMP and rrdtool is a nice combination and problably I will find soon more 
details to monitor close. The unique issue I find is graph the hypervisor 
CPU, Xen VPCU dynamic pin do stranges things here.

Ah! And xentop appears to diverge some times.

This list accept attachments? If yes I can send it here.

Unhapinness no, its been used in a internal product of my enterprise but I 
could say to see on RRDs perl manual that comes in the rrdtool, the PHP just 
generate commands from system and capture the PNG on HTML. 

But like I said there are freesoftware solutions, Cacti and MRTG. I do not use 
this because we are creating a entire host/networking monitor system to 
assist my employees, and we are customizing so much that we abandon the idea 
to use some existing solution, our code comes from scratch. :-) Soon we will 
integrate this with IDS and perhaps some IA algorithms to discover flaws. In 
a not fair future (I hope) also will put extreme hardening for secure 
purposes too.

This might be more than what you are looking for, but you may want to
have at

Versiera (https://www.versiera.com/). There is no cost to the hosted
service. 

Register for an account, download and install a host agent in Xen. Quick
and

easy.

 

Agent communications are secured with digital certs. You will be able to
get performance

info, and lots of system information down to the process and
communication levels.

May be overkill for what you want. I should disclose I work for the
company, if you

need more info send me an email.

 

There are lots of other choices out there you may want to consider
including Nagios,

Fiveruns, Spiceworks, Heroix...

 

Frank
