Agentless Mode - Monitor Disk Space

Hi guys, I have 100 VMs running Windows 7. All I wish to do is monitor the free space on them so I installed the agent on a server VMand I'm trying to use it as a proxy to agentless monitor disk space on them. I can't figure out though how to get the disk
space monitor to fire against them agentless. It doesn't seem to discover the disk instances against them. Is there a guide for this somewhere?

I should have been more specific.
There are no internal firewalls software or hardware based
Remote registry is ruing on all machines.
The SCOM action account is a full admin on al client machines
The issue is that the logical disk are simply not being discovered agentlessly. How to troubleshoot this? I see messages like this on my Proxy agent:
The Registry Probe could not collect the following attributes from the registry of the computer 'myvm.mydomain.com'.
AdvisorConnectorActivated: 0x80070005 (Access is denied.
Version: 0x80070005 (Access is denied.

Archivelog mode ans disk space

Hi,
when we are in archive log mode, how disk space would be occupied ? Where the archive files would be put ? How the disk space can be controlled and managed ?
many thanks before.

1. how disk space would be occupied ?
It depends, mostly of your redo log size and amount of transactions you are going to have.
Where the archive files would be put
I assume you are not going to transfer these archive logs to a standby database.
If you don't use flash recovery area for this purpose then you have to specify location in log_archive_dest_n parameters.
If you use flash recovery area, then by default archive logs will be saved at destination specified in db_recovery_file_dest parameter.
How the disk space can be controlled and managed ?
Can you be more specific on this one?

SCOM only monitoring disk space of a group of servers

I have been looking for a way to setup SCOM to ONLY monitor the disk space on a specific group of servers.
We have a sandbox environment that consists of approximately 100 servers. The only responsibility we have is to make sure these machines are patched. Everything else related to the OS and Software is handled by the developers who own the sandbox,
so no other monitors are needed. Microsoft patches are failing because some of the C drives do not have enough disk space. Is there a way to discover these servers and only have the disk monitored? All other monitors in SCOM can be ignored on these
servers.
Thanks for any assistance that can be provided.

Without knowing what else you have in your SCOM environment, it could be a lot of work to start excluding this group of servers from all the other monitoring you have.
Other options you could consider are to allow the servers to be monitored, but somehow exclude those alerts from being sent in any subscriptions, or putting the components of those servers into Maintenance Mode other than the C: drives, but both of these
options will still collect information on these 100 servers and take space in your SCOM DBs.
You can refer to this page for how to use the free space monitor and override it for a group that will target your 100 servers. http://blogs.technet.com/b/jonathanalmquist/archive/2009/04/04/logical-disk-free-space-monitor.aspx

Monitor disk space using alerts

I need to receive an email when a disk space on a given drive (which has SQL DB files) falls below 3 GB:
- I need to use alerts (I don't want to use a SQL job to run some SP every x mins).
- SQL Server performance condition alert cannot be used, because SQL cannot access non-SQL performance counters
- if you use WMI event alert, please provide a query
- registry cannot be modified (I know what you were thinking)
Seems like a rather common DBA need, and I can't find a solution. Thanks in advance.

Try this SQL Server alert .You need to use database mail and then the operator to send the mail ..Modify it as I have kept the > 800 value and you need to use < sign ...

Conky to monitor disk space.

Okay, I'm trying to modify Southie75's conky config for my own use, and running into some problems.
Here is the disk part of the config:
${alignc}Disks
${alignr}Writes/Reads
Root ($color${fs_type /}${color0}) ${alignr}$color${diskio_write /dev/sda2}${color0}/$color${diskio_read /dev/sda2}
${fs_used /}${color0}/$color${fs_size /} ${alignr}$color${fs_used_perc /}% ${color0}${fs_bar 8,100 /}
Vista ($color${fs_type /home/southie/vista}${color0}) ${alignr}$color${diskio_write /dev/sda1}${color0}/$color${diskio_read /dev/sda1}
${fs_used /home/southie/vista}${color0}/$color${fs_size /home/southie/vista} ${alignr}$color${fs_used_perc /home/southie/vista}% ${color0}${fs_bar 8,100 /home/southie/vista}
Backup ($color${fs_type /home/southie/mnt}${color0}) ${alignr}$color${diskio_write /dev/sdb2}${color0}/$color${diskio_read /dev/sdb2}
${fs_used /home/southie/mnt}${color0}/$color${fs_size /home/southie/mnt} ${alignr}$color${fs_used_perc /home/southie/mnt}% ${color0}${fs_bar 8,100 /home/southie/mnt}
Now, my version:
${alignc}Disks
${alignr}Writes/Reads
Root ($color${fs_type /}${color0}) ${alignr}$color${diskio_write /dev/sda2}${color0}/$color${diskio_read /dev/sda2}
${fs_used /}${color0}/$color${fs_size /} ${alignr}$color${fs_used_perc /}% ${color0}${fs_bar 8,100 /}
Home ($color${fs_type /}${color0}) ${alignr}$color${diskio_write /dev/sdd4}${color0}/$color${diskio_read /dev/sdd4}
${fs_used /}${color0}/$color${fs_size /} ${alignr}$color${fs_used_perc /}% ${color0}${fs_bar 8,100 /}
Anime ($color${fs_type /media/Anime}${color0}) ${alignr}$color${diskio_write /dev/sda1}${color0}/$color${diskio_read /dev/sda1}
${fs_used /media/Anime}${color0}/$color${fs_size /media/Anime} ${alignr}$color${fs_used_perc /media/Anime}% ${color0}${fs_bar 8,100 /media/Anime}
Storage ($color${fs_type /media/Storage}${color0}) ${alignr}$color${diskio_write /dev/sdc1}${color0}/$color${diskio_read /dev/sdc1}
${fs_used /media/Storage}${color0}/$color${fs_size /media/Storage} ${alignr}$color${fs_used_perc /media/Storage}% ${color0}${fs_bar 8,100 /media/Storage}
It seems to work, but the probem is that every time I show down my computer and boot it up again, conky will not start because the /dev/XXX has changed. I asked about this on IRC, and was linked to the wiki about persistent block device naming (http://wiki.archlinux.org/index.php/Per … ice_naming), but I don't really understand how to make it work with the conky config.

Then I ran
df -l
and saw that the drive I wanted was:

and conky says
Conky: diskio device '../../sda1' does not exist
Conky: diskio device '../../sda1' does not exist
What did I miss? Do I need to include that whole first part too?

Alert on Low disk space

Hi All
I have created an alert of WMI event in sql server which send mail if disk space on D drive is less than 10GB
Query :
SELECT * from __InstanceModificationEvent
WITHIN 60
WHERE
TargetInstance ISA 'CIM_LogicalDisk'
AND
TargetInstance.FreeSpace < 10000000000
AND
TargetInstance.DeviceID = 'D:'
when I enable this alert It sends alert for low disk space
but some time it does'nt send alerts. I am not sure when this __InstanceModificationEvent occure
and is there any another way to alert low disk space in my mailbox

How to monitor available disk space in archive directory

I need to monitor the available disk space of the archive directory during a long running PL/SQL program which does a lot of inserts and updates. This program is running in a background session and should regularly check for the available space. If there is less then a customizable number of MBs free the program must terminate itself. How can I access this information from the file system? (I'm using 8.1.6 and the application will run on both AIX and NT)

The directory itself is not taking space (It actually does but in most cases you can neglect its size). It is files that it has that take space. Also, the more files you create the more space gets allocates from the media that holds them. And the last, the media (Hard Drive, Floppy, or other) has free space, not directory. That is how all OS's that I know about work.

Disk Space Monitor

hi
I have set up a logical disk space monitor for windows 2012 servers on my Operations manager 2012. The threshold value is 500MB. However, No alert is generated even when my disk has exceeded 500MB. It works when i set the threshold below 100 MB. Can you
please help out on this? Is it because of the wrong instance ?
The object has been specified as "Logical Disk"
Counter is %free space and the instance is the C:\ drive.

Does you using Logical Disk Free Space, from Windows Server OS Management Pack, in monitoring the free disk space?
Case 1 Logical disk Free Space Monitor:
It will generate alert if both the conditions, disk free space and % of free disk space, are below threshold.
Recommendation: You may enable another monitor ,Disk Free Space (MB) Low, which is disable by default.
Case 2 you own custom monitor:
Please dump your setting for troubleshooting

Disk Space Monitoring Tools

I'm looking for a tool that will monitor all of my X-Servers and display the disk space for all of them within one application. If anyone knows of one, please let me know.

Disk Space Monitors

If you can't get the customization for space alerts with SW you can always use one of many free utilities:
http://community.spiceworks.com/product/47308-disk-space-monitor

We have quiet a few servers on our network.
I want to be alerted and have a ticket created for when their disk space is at a certain point.
Spiceworks notified us when there was less than 10% space free which is great. But we then realized that we would like to be notified at different percentages and also notified for how many GB are left instead of a percent. Sadly, There are only a few options and we would like to have a monitor that tells us less than 50 GB or less than 20 GB, but we can't seem to figure out how to add more options that it offers.
HELP WITH THIS ASAP, would be greatly appreciated.

SCOM cluster disk space monitor

Hi Guys,
Can we monitor the cluster disks thresholds by taking the samples as we do in the logical disks??
Because i cannot see that option coming in the cluster disk space monitor when i am overriding the monitor.There is no option for the number of samples coming in that. I want the monitor to check the utilization three times and if it exceeds then generate
an alert.
Thanks
Ashish

Hi,
As you mentioned, threre is no option for the number of samples, you may need to rewrite the MP.

Lost 110 GB of disk space after deleting files in target mode... A mystery?

Dear all,
Yesterday, I used my MBP in Target Disk mode and deleted a directory with approx. 110 GB of files in it. Now I found out that this space is mysteriously gone: the available free space on my hard disk did not increase, and the files are not in the trash or anywhere where I can find them.
I tried Disk Utility doing ‘Verify Disk’ as well as ‘Repair Disk Permissions’, but with no success.
Could any one advice me how I can recover my disk space?
Thanks in advance....
/Rudi

Thanks, Tony.
No, they are not in the trash of the other computer. It would also have taken the computer a while to transfer these files (110 GB takes a while, even over FireFire 800).
The issue is not that I want to recover these files (I have backup copies), I just would like to have my disk space back. It is siting somewhere but 'lost' to the DOS.
Best, Rudi
