How can I get this in devstack user interfaces.
Please help..
Thanks in advance
its not available in openstack icehouse/juno version though it can be edited in juno to retrieve in devstack.
I didn't use openstack Kilo. In juno, if your hypervisor is libvirt, Vsphere or XenAPI then you can retrive this statistics in devstack UI. for this you have to do this:
For Libvirt
In this location ceilometer/compute/virt/libvirt/inspector.py, add this:
from oslo.utils import units
from ceilometer.compute.pollsters import util
def inspect_memory_usage(self, instance, duration=None):
instance_name = util.instance_name(instance)
domain = self._lookup_by_name(instance_name)
state = domain.info()[0]
if state == libvirt.VIR_DOMAIN_SHUTOFF:
LOG.warn(_('Failed to inspect memory usage of %(instance_name)s, '
'domain is in state of SHUTOFF'),
{'instance_name': instance_name})
return
try:
memory_stats = domain.memoryStats()
if (memory_stats and
memory_stats.get('available') and
memory_stats.get('unused')):
memory_used = (memory_stats.get('available') -
memory_stats.get('unused'))
# Stat provided from libvirt is in KB, converting it to MB.
memory_used = memory_used / units.Ki
return virt_inspector.MemoryUsageStats(usage=memory_used)
else:
LOG.warn(_('Failed to inspect memory usage of '
'%(instance_name)s, can not get info from libvirt'),
{'instance_name': instance_name})
# memoryStats might launch an exception if the method
# is not supported by the underlying hypervisor being
# used by libvirt
except libvirt.libvirtError as e:
LOG.warn(_('Failed to inspect memory usage of %(instance_name)s, '
'can not get info from libvirt: %(error)s'),
{'instance_name': instance_name, 'error': e})

Evidently the Windows dos cmd "tasklist -v " is truncating lines after so many characters.
My perl program is reading in special command processes to compare against processes stored in my database. I am trying to make sure expected processes are running.
Unfortunately the script fails since one of my 50 or so processes is truncated by "tasklist -v".
Is there an alternative command?
Thanks,
Sammy
Following code demonstrates usage of tasklist /fo table command as a pipe input for further processing
Tip: help tasklist
use strict;
use warnings;
my $regex = qr/^(?<name>.*?)\s+(?<pid>\d+)\s+(?<session_name>\S+)\s+(?<session>\d+)\s+(?<mem>.*)/;
$^ = 'STDOUT_TOP';
open my $pipe, 'tasklist /fo table|';
/$regex/ && write for <$pipe>;
close $pipe;
$~ = 'STDOUT_BOTTOM';
write;
exit 0;
format STDOUT_TOP =
+----------------------------------+------------+----------+---------+-----------+
| Name | PID | SessName | Session | Memory |
+----------------------------------+------------+----------+---------+-----------+
.
format STDOUT =

I can see that it is possible to add metadata to a Rackspace virtual machine instance.
I want to get a list of running instances, filtered by a particular metatag value.
I can't see how to do so in the documentation however.
is it possible?
You should be able to do so using the openstack client... but it depends on which metatag you're interested in.
You can get a list of all servers:
openstack server list

openstack --f json will output the same stuff but in json format that you can more easily manipulate programmatically.

#+TBLFM: $5=vsum($6..$>);NE
As you see ,the formula $5=vsum($6..$>);NE can't be calculated! Here is debug info:
Substitution history of formula
Orig: vsum($6..$>)
$xyz-> vsum($6..$>)
#r$c-> vsum($6..$>)
$1-> vsum((0)..$>)

Error: Expected `)'
But if I replace the formula with $5=vsum($6..$17) and then it works ,I can't figure out where is the problem?
I need some help ,appreciate it!
For some reason, I cannot get HandlerSocket to start listening when I start mariadb (version
10.0.14). I am using Cent OS 6.5.
my.cnf has the following settings:
handlersocket_port = 9998
handlersocket_port_wr = 9999
handlersocket_address = 127.0.0.1
Calling "SHOW GLOBAL VARIABLES LIKE 'handlersocket%'" from the mariaDb prompt shows:
+-------------------------------+-----------+
| Variable_name | Value |
+-------------------------------+-----------+
| handlersocket_accept_balance | 0 |
| handlersocket_address | 127.0.0.1 |
| handlersocket_backlog | 32768 |
| handlersocket_epoll | 1 |
| handlersocket_plain_secret | |
| handlersocket_plain_secret_wr | |
| handlersocket_port | 9998 |
| handlersocket_port_wr | 9999 |
| handlersocket_rcvbuf | 0 |
| handlersocket_readsize | 0 |
| handlersocket_sndbuf | 0 |
| handlersocket_threads | 16 |
| handlersocket_threads_wr | 1 |
| handlersocket_timeout | 300 |
| handlersocket_verbose | 10 |
| handlersocket_wrlock_timeout | 12 |
+-------------------------------+-----------+
I can start mariadb successfully, but when I check to see which ports are actively listening,
neither 9998 nor 9999 show up. I've checked the mysqld.log file, but no errors seem to be occurring.
Answering my own question here -
SELINUX needed to be set to permissive mode to get HandlerSocket started.
Here is my table

What's wrong? Why $Hi was not substituted?
Ah, found it by myself. Here is wrong row, and the fixed row:

| $ | price = 75 | Hi=2.9 | | | | |
