Any chance of adding memory utilization to this?

When I use the snmpwalk command I got the following message.

[root]# snmpwalk -v2c -c public x1.x2.x3.x4 NET-SNMP-EXTEND-MIB::nsExtendOutputFull.\”xen-stats\”
NET-SNMP-EXTEND-MIB::nsExtendOutputFull.”xen-stats” = No more variables left in this MIB View (It is past the end of the MIB tree)

Thanks for your help

Hi Ian.

I’m using Xen 3.1 on FC8 and I can’t do your template works for my Cacti.

Could you help me?

I’ve done everything you said here on Dom0. That’s right?
Do I have to do something on DomUs?

I would be very grateful if you could help me by mail. I’ll use it in my Graduation Project.

Thanks!

if you’re trying to use PHP4, that would probably explain it. I’m not sure I do anything that’s specifically PHP4, but I WILL NEVER write PHP4 compatable code ever again

I’ve no idea what the hash problem is about, if you can’t get it working drop me a mail for my consultancy rates. Good luck!

Hello,

I have installed cacti to make use of your work here. When i try to import the template ‘cacti_data_query_xen_cloud.xml’ file into cacti i get an error: “Error: XML: Hash version does not exist.”

Also if i run the command from the previos posts: ‘/usr/bin/php /usr/share/cacti/site/scripts/xen_cloud_stats.php query xen_name’

i get the error: “Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /usr/share/cacti/site/scripts/xen_cload_stats.php on line 27″

am i missing something?

I am trying to gauge how stressed the physical CPU is on any one dom0.

If I were to add a TOTAL cdef on the cpu_sec, would it all add up to 1 second on average – for a single core system? and 4 seconds for a quad core?

I have the graph – but I can’t share it with you here..

Your PHP install doesn’t have SNMP support. Install the module, or recompile, or whatever you need to do for your chosen distro
