Capture process hung to get stat
We have a (500 + vms) environment where the often time it's hanging processes. We observed the indication is flawed CPU utilization over a period of time.
Say if there is a virtual machine with regular use of the UC 40% more than a day, it is assumed that there are bad processes runs, because an idle process should be less consuming.
That being said. Is it possible to interrogate vms and return the VMS with stale CPU usage? I think I use get-stat and look for the value non-zero but doesn't seem to work. Any thoughts?
Try like this, she adds a condition to see if the average CPU usage is greater than 20%
Group-object VM | %{
$values = $_. Group | Tri-objet-time property | %{$_. CPU}
$avg = $_Group | Measure-object-property CPU-medium | Select average - ExpandProperty
$stdvar = get-WelfordStdVar-samples $values
If ($avg - gt 20 - and $stdvar - the $threshold) {}
$_ | Select Name,@{N='StdVar'; {E = {[Math]: Round($stdvar,2)}}, @{N = 'CPU'; {E = {[string]: Join('/',$values)}}
}
}

Can Service capture/process of Script error in the Service of the company?
We have a Service of Script invoked by XAI Inbound Service that calls a Business Service. If an error occurs in the Baltic States, we would like to capture/process within the SS, rather that the process 'faulty '...
For example, the CC & B demo database includes SS CI_MRInput and BS CI_RegisterReadHighLowLimits (see CI_MRInput script below).
In the demo environment, the CI_MRInput is called by a Script CI_MRRouteA BPA, in which case "warn" can be specified for the processing of the effect of the error.
However, when it is called via the Service entering of XAI, a mistake of the BS (ex: 8:11024) causes the process CC & B 'fail' and a mistake SOAP and/or CC & B the details of the error to send to the external process. This is not desired.
Ideally, we would like to than the SS to catch the error and send an agreement on the error code of the external process.
Any help in this matter will be greatly appreciated.
CI_MRInput Service script:

Get-stat for monthly trends of data warehouses
Hi all
Long time lurker of time,
I have not been using PS for long and mostly just pin out one liners for things like "whats connected to X", etc.
I'm trying to output a file that I can put in excel and create configured vs used graphics is the idea.
I would like to get this down so I can manipulate to other entities.
I can wrap this around a foreach loop that I can usually understand.
With get-stat, I noticed that he gets a single value, then the other so the MetricID is evolving, so I can't just select the property.
I have a script already where I show the last value and then put them all on the same graph, but it would be cool to have a chart with the data store to see the trends.
We have vcops, but I find the graphics a slow process, because we have dozens of warehouses of data around the world.
It's my script simple I must then cut and paste the values into additional columns, but who wants to do it manually
I can do something like this
$todayMidnight = (get-Date-time Minute 0 - 0 - 0 second)
$Startmonth = - 1
$metrics = "disk.capacity.latest", "disk.provisioned.latest", "disk.used.latest".
$datastore = "vm_production01".
$arrds = get-datastore. WHERE-object {$_.} Name - like $datastore}
$a = get - Stat - $arrds - Stat $metrics entity [0] - boot $todayMidnight.AddMonths ($Startmonth) - complete $todayMidnight | where {$_.instance - eq ""} | Sort the timestamp | Select the timestamp value
$b = get - Stat - $arrds - Stat $metrics entity [1] - boot $todayMidnight.AddMonths ($Startmonth) - complete $todayMidnight | where {$_.instance - eq ""} | Sort the timestamp | Select the value
$c = get - Stat - $arrds - Stat $metrics entity [2] - boot $todayMidnight.AddMonths ($Startmonth) - complete $todayMidnight | where {$_.instance - eq ""} | Sort the timestamp | Select the value
$fin = $a + $b + $c
$fin = $a + $b + $c
$fin | ConvertTo-Csv | Out-file C:\support\scripts\development\datastoreusage.csv
See the attachment for the final goal.
I don't know if I need to create a custom object to accomplish, if someone could help me that would be great.
and none of the useful articles where I can learn to do it, I'm almost finished powershell in a month of meals but I do not think that this is covered
Thank you all
To run this for all your storage data and then create a spreadsheet with the data store, you can use the function of export-Xlsx .
The script should look like this
$todayMidnight = (get-Date-time Minute 0 - 0 - 0 second)
$Startmonth = - 1
$metrics = "disk.capacity.latest", "disk.provisioned.latest", "disk.used.latest".
$ds = get-Datastore
$xlsxPath = "C:\ds-report.xlsx".
Get-Stat - $ds - Stat $metrics entity - boot $todayMidnight.AddMonths ($Startmonth) - complete $todayMidnight |
Group-object - property {$_.} @entity.name} | %{
$dsStats = $_. Group | Group-object - property Timestamp | %{
New-object PSObject-property @ {}
Timestamp = $_. Name
'Capacity (GB)' = [Math]: Round (($_.)) Group |
where {$_.} MetricId - eq "disk.capacity.latest" - and $_. ({Instance - eq ' '}). Value / 1 MB, 2)
'Allocated (GB)' = [Math]: Round (($_.)) Group |
where {$_.} MetricId - eq "disk.provisioned.latest" - and $_. ({Instance - eq ' '}). Value / 1 MB, 2)
'Used (GB)' = [Math]: Round (($_.)) Group |
where {$_.} MetricId - eq "disk.used.latest" - and $_. ({Instance - eq ' '}). Value / 1 MB, 2)
}
}
$dsStats | Tri-objet-Timestamp property |
Select the Timestamp, 'Ability (GB)', 'allocated (GB) ', ' used (GB) |

Get-Stat for use of the power of the ESXi Server
Hi all
Need your help to get a script to capture power consumption/use of an esxi host. I checked the command get-stat, I don't see any special argument as energy consumption in check for the host entity. The time interval can be anything, I'd like to see the same values that manifest slot for power under the tables of performance of an esxi host.
Any help would be appreciated.

Capture process not queue message
DB version: 10.2.0.4
I'm trying to set up a simple capture process. The streams administrator (for example APPS) is the owner of the queue and the owner of the base table. I perform the following steps:
1 configure the queue using dbms_streams_adm.set_up_queue
2. Add a rule table using dbms_streams_adm.add_table_rules
3 start the capture process using dbms_capture_adm.start_capture (or EM console)
I'm not instantiate the table of base explicitly, as it is documented in the Administrator's guide that "dbms_streams_adm.add_table_rules" will implicitly do the same.
Once I have insert / update the base table, v$ streams_capture watch TOTAL_PREFILTER_KEPT get incremented properly.
Again, I see no message queue implementation in the queue of the watercourse.
Grateful for the help in diagnosing the problem.Hello
You have either a spread set on the same queue of capture (stream queue) or a posting on the queue of capture? From your explanation, it seems that you only have a queue of flow and a captrue with certain rules of capture process. Let me know.
Thank you

The validation process hung for a table only!
Hi all
There is a table contains 79 columns (with a cloumn CLOB) with about 100 000 record, sometimes a problem occurs only with this table (and only these days) when you attempt to insert, update, delete from this table, the validation process hung! Why? and how to solve? I can't say why this problem occurs.
We renamed the table and re-create using EXPDP, IMPDP orders, re-create triggers on it and repeat grants thereon to the roles that the previous, this procedure has solved the problem for maybe one day only, but the problem returns!
Notes:
This table is on a table space users, otherwise I use DB Oracle 11 g R2
> The question is: What does it mean the blocking locks? and why this problem occurs? and how to avoid it from happening again?
Have you read this:
https://docs.Oracle.com/CD/E18283_01/server.112/e16508/consist.htm
For example, this part:
Written in conflict read-committed Transactions
In a read committed transaction, a write conflict occurs when the transaction attempts to change an update by a simultaneous uncommitted transaction line, sometimes called a blocking transaction.
The read committed transaction awaits the transaction that blocks at the end and release his lock of line. The options are the following:
-If the blocking transaction is cancelled, the pending transaction then proceeds to change the locked row previously as if the other transaction never existed.
-If the blocking transaction is committed and frees its locks, then the transaction pending proceeds to update scheduled for the newly modified line.
> Where can I find this log file please?
For example:
C:\app\oracle\diag\rdbms\oracle\orcl\trace\alert_orcl.log

It is somewhat related to the issue you reported in metric does not exist, but the documentation says it should
This output, it seems that you are connected to a node ESXi, not a vCenter or both.
View the contents of $global: defaultviservers to check.
On a node ESXi, you get only 20 seconds intervals (for the +/-breaking).
I suspect that this node ESXi was started, where the limited number of parameters returned.
If this is not the case, then there is a problem with the PerformanceManager on this node ESXi.

I'm looking to use get-stat to get some associated information networks. Here's what I do:
Select a group of virtual machines
for each virtual machine, select only the 1 (vnic1) virtual network adapter not vnic 2. (some virtual machines have vNIC 2 or more)
find the maximum flow of avg in Mbps for the virtual NIC only. Make it as specific as I can according to statistics level 1. PIC of the last 24 hours is OK. (I want to predict the peaks)
Create a table as below, I can export to CSV.
Ideas?

Get-stat on the syntax and parameters
Where can I find a * complete * reference to the cmdlet get-stat, including:
- All entities, I can ask
- All the stats, I can tell (if possible, divided by entity)
examples I can take as an example?
I was able to locate dozens of interesting pages and samples, but no reference complete...
Concerning
Marius
It is a response of 2 parts:
- The syntax of the cmdlet Get-Stat is documented in the cmdlet help page (do a Get-Help) and in the reference online (see link)
- The metrics are documented in the SDK reference under the heading PerformanceManager
For point 2, you also use my Stats Toolbox.
For example on the use of Get-Stat have a peek at all my performance statistics related messages.
And there are of course many examples available in this community.

A customer using a (free) ESXi host reports serious performance problems.
My goal is to see if performance issues are due to memory, CPU, disk, or any other component.
I've created a PowerCLI script to query the ESXi host to collect conters performance.
Before starting can use, I assess whether the use of get-stat can aggravate the problerms with the performance of the ESXi host?
My script should begin every 60 senconds, use the "connect-viserver" cmdlet and then cycle delivering approximately 20 times the cmdlet "get-stat' to get the values such as"cpu.usage.average","mem.usage.average"and so on.
Can it worsen the performance of the target ESXi host issue?
Should I before statring to use it?
Will there be a better strategy to collect performance counters?
Concerning
Marius
Performance in real time on an ESXi node are maintained during +/-1 hour, so I would not ask as often as every 60 seconds.
The cmdlet Get-Stat imposes some overhead on the ESXi node, then Yes, that this can have an effect on the interpretation of the node ESXi.
A few other tips to lower to load:
- use only the counters that you absolutely
- try to locate the source of the problem with a minimal set of counters, then go down by adding several counters
-
Using the cmdlet Get-stats for the problems of performance of ESXi
I need to detect the bottlenecks (if any) causing poor performance with a (free) 5.5 ESXi host.
I see that if I use the cmdlet Get - stat PowerCLI I get dozens of meters, such as "mem.usage.average" or "'rescpu.maxlimited1.latest ', just to give two samples. "
Can I identify a subset of the counters I should follow to identify possible bottlenecks in the fastest way possible?
Concerning
Marius
Everything depends of course.
There are several positions which list a number of key counters to watch.
The Hosts of ESXi monitoring - a deeper on the what and the why look , you will find a good starting set.

Hello
I went through the various threads for a debate on the output of the Get-Stat '-drive ' element as he tries to understand the OPS are / s of a VM. When you run the command, I went back to "disk.usage.average" where the "Description" indicates that this is below the average disk i/o rate, however the area of the 'unit' claims that the measure is in Kbps.
I expected the field unit as IOPS / s which in itself is a unit of measurement? Or that I get it wrong?

Average usage of the CPU with get-stat
With get-stat, I can get average use of the processor in MHz using the metric usagemhz.
However, by default the maximum and minimum values in MHz is not in data points from 2 months ago. That's fine if I want to just average, but I also need average peak values. The average maximum CPU usage is possible with powerCLI?
The thing is that when you have found these averages and you do that a day or a week of a data value is not enough to really give you a true picture - you need 2 - 3 months. Can Haw I achieve this with PowerCLI?
1. you can easily adapt the cmdlet Get - VM to produce the result for 1 or a limited set of the virtual machine
For example:
Get-VM-name MyVM | Select...
Returns the result for 1 computer virtual called MyVM
If you do
Get-VM-name my * | Select...
It returns results for all virtual machines whose name begins with "My".
2. that's because Select-Object generates a hash table, and by default PowerShell displays like that hash tables.
To get only the value real exchange the last select like this
...
