• How to calculate the IOPS datastore / s and latency via Powercli?

  Hi all!

  I want to calculate the IOPS / s (RO/RW) and the latency of the data via Powercli store, but I cant' find this metric in Vcenter (in the data store tab) and see no metric for data via the cmdlet Get-Stat store.

  How can we measure IOPS / s and latency of data store?  For example I know veeam monitor this information - http://cdn.swcdn.net/creative/v16.8/images/screenshots/products/VM/Lg/EN/VMan60-Orion-Datastore-Top_Lg_960x540.jpg

  I know, I can get this VM or vmhost metric, but I need information on the data store.

  How to measure for IOPS / s and latency of data properly store?

  Thanks in advance!

  These measures are collected on ESXi nodes, entity would need to have the ESXi nodes where these data warehouses are connected.

  You can use the Instance property to filter.

  Under the PerformanceManager , you see all the measures for each indicator it indicates under which entity this metric is collected.

  

  And Yes, the cmdlet Get-inventory returns no data warehouses.

  There is a little, aggregated metric for data warehouses, I'll have to find an alternative for those.

  Nice catch!

• How to calculate the number of Out_flags for the PIPL?

  Hey everybody!

  I'm kinda new to After Effects of programming, so I hope I'm not asking an obvious question.

  I searched the web and this forum but just could not find a solution to this problem.

  Compilation of my plugin works fine, but as soon as I select it from the menu effects I am presented with an incompatibility error.

  My question (already in the title): how to calculate the correct number for the global_out_flags pipl?

  Thanks in advance,

• Calculate the disk space required for the INDEX

  Hello
  
  How to calculate the disk space required to create an INDEX? Please tell me where I can get the details of resources.
  
  For example:
  I need to create a non-UNIQUE INDEX on the columns, an approximate size would do.
  
  < PRE >
  NOT NULL DATE EVENT_DATE
  APPT_DATE_SLOT VARCHAR2 (15)
  EVENT_STATUS VARCHAR2 (4)
  < / PRE >
  
  The table has some 7 300 000 rows. I would like to know how to calculate too.
  
  All AIDS are very much appreciated.

  A rough estimate of the index space will need is possible by

  adding the actual length expected from each column, plus 6 for the rowid, 2 for the number of the X-header of the rows in the table that will be so an entry

  Date are 7 bytes internal + 15 + 4 + 2 + 6 = 34 X 7.3 M = 248200000 X General fresh for the block header, initrans, etc...

  We will use 20% overhead block or 1.2 X 248200000 = 297840000, which is about 285 M

  The actual distribution will vary according to your method of range tablespace.

  The code expects milliseconds, then 26 seconds would be written as
  this:

  26000

  If he said 01:22 (one minute and 22 seconds), you must write it like this:

  82000

  ... which is 60 seconds for now, 22 seconds
  side, then multiplied by 1,000 to get milliseconds.

• Choosing the thin client just for our solution! (health care)

  Hello community,

  I can't try to define the best thin client PCOIP solution so that I work at the hospital.

  We are currently working with Vmware view 4.5 with Oracle sunray thin clients/broker

  It works very well with smart card authentication, but we want to feature implend instead of RDP PCOIP

  and get rid of the sunray broker because he dousent enters our landscape.

  Now that we're about to go upscaling (from 100vm to 1000vms) as possible, we are looking for the right thin client

  We tried the new dell Fx130 & 170 with the dell Detos reference edition

  However, we feel its underdeveloped and it can not handle the Pre-os how smart card authentication

  customers current sunray are skillfully to (follow me desktop) and lacks a disconnect button.

  Ideally:

  1. We do not want a built-in windows machine since it's patching/security on the thin client
  2. It's a simple thin/zero client that we can manage a centralized management point.
  3. who has PCOIP functionality
  4. A biometric capability / card smartcard/proximity (if necessary with another agent of connection)
  5. and has a material disconnect as button
  6. Follow me / roaming Office

  Can someone help me in the forest of solutions and thin clients or push me in the right direction?

  Any help is appreciated!

  This can be done with the power button. Push, little time to disconnect it take longer to power off of NC

• With the help of Max for alphanumeric values

  Currently I have a column varchar2 with the following data
  

  NPT_Code
  NPT00001
  NPT00112
  NPT03019A
  NPT00419

  Try to find a way to remove all the letters and get the next highest value increase.
  
  Numbers are always set to 5. Letters from there always 3 to the left. and sometimes, there is a letter to the right.
  
  I was going to mak a sequence and manually to the search for the greatest number in this column and just start from there, but I was wondering if anyone else knows another solution that uses max or something simliar.
  

  Select Max(NPT_Code) + 1 into l_NPT_CODE FROM TABLE
  
  UPDATE TABLE
  SET NPT_CODE = L_NPT_CODE
  WHERE ID = XXXX;

  Hello

  Here's one way:

              )     AS number_value
  FROM    table_x

  number_value will be the number 3019 if string column is one of the following strings:
  NPT03019A
  NPT03019
  T03019
  03019NPT
  NPT3019A
  NPT0000003019A
  03019
  3019

  You can then use number_value functions such a MAX.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• View the IOPS / s Maximum

  Y at - it a tool that will show us the actual IOPS / s max for our group? The iops max estimated in the experimental SAN HQ analysis jumps around a bit, and of course, there is an opposition heavy depends not downsizing. Or if someone already knows specific combinations, we have a PS6000 and PS6210xs joined a group.

  Thank you.

  Hello

  The experimental is as close as you can get.  Since Max IOPs varies based on the size of the blocks and sequential or random.  You can have MAX for a given set of values.   Large block sizes higher throughput at the expense of the IOs per second.  The reverse is true as well.

  I did the following, but I think something's wrong here:

  timeInSecFromStart = 02:00:05

  But it should be exactly 00:00:05.

  What is a problem?

  Because, as I said, a Date to measure a moment in time, not a period. So when you have 5000 ms, and you that transform a Date, this means that 5 seconds after the time, which equals 00:00:05.000 01/01/1970 GMT.

  As I said, if you are not currently in GMT, then you must set the DateFormat GMT TZ. Right now, it's to show you the time in your TZ. If you have included the date in your SimpleDateFormat, you would see the 01/01/1970 or 31/12/1969, function that TZ you find.

  Bottom line: you try to use these classes in a sense they are not intended for, and while you can get the results you want for a limited set of entries if you understand how these classes and how to work with it, it is a fragile approach and comes with all sorts of warnings warning.

• get the IOPS / s and flow rate for each card of vmhba

  Hi, I have seen a few difficulties for the IOPS / s and flow stat for esxi for each vmhba card get the average, max, min

  I can get some network like net.usage.average, net.received.average and net.transmitted.average parameters as the metric is consolidated for all the network card.

  Here is the part of the classic script I use

  $metrics = "net.received.average", "net.transmitted.average".

  Get-Stat - entity $esx - start $start - finishing $stop - MaxSamples 10000 - Intervalmin 30 - stat $metrics |

  Group-object - property {$_.} @entity.name} | %{

  $esxname = $_. Group [0]. @entity.name

  $hard = (get-VMhost-name $esxname) .extensiondata. Summary.Hardware

  $netreceived = $_. Group | where {$_.} MetricId - eq "net.received.average" - and $_. {Instance - eq ""} | Measure-object-property value - average - Maximum - Minimum

  $nettransmit = $_. Group | where {$_.} MetricId - eq "net.transmitted.average" - and $_. {Instance - eq ""} | Measure-object-property value - average - Maximum - Minimum

  and so now, but on the storage card, consolidated metrics do not exist...

  Thank you very much!

  Try something like this

  $esx = Get-VMHost MyEsx$stat = "storageAdapter.numberReadAveraged.average","storageAdapter.numberWriteAveraged.average"$start = (Get-Date).AddMinutes(-5)
  
  Get-Stat -Entity $esx -Stat $stat -Start $start |Group-Object -Property Instance,Timestamp | %{$_ |Select @{N="Timestamp";E={$_.Values[1]}},@{N="Instance";E={$_.Values[0]}},@{N="Read IOPS";E={$_.Group | where {$_.MetricId -eq "storageAdapter.numberReadAveraged.average"} | %{$_.Value/$_.IntervalSecs}}},@{N="Write IOPS";E={$_.Group | where {$_.MetricId -eq "storageAdapter.numberWriteAveraged.average"} | %{$_.Value/$_.IntervalSecs}}}}
