Performance metrics & Performance alerts in BI

Hi Experts,
I want to know about the below topics under Business intelligence(BI)
1) Performance metrics
2) Performance alerts
Provide some website links for the above links.
Regards,
Krishna Balaji T

As I understand,the question seems more functional then technical so take a look at the wiki also BPX in SDN.

Custom CCMS metrics and alert in solman 7.1

Friends,
I have created custom CCMS metrics and alert in solman 7.1 as per below document.

I am getting the alerts generating in the RZ20 in the target system but not getting the alerts on mail. (attached image)
Anyone have any idea?

Hi,
Can you please check the standard job SAP_CCMS_MONI_BATCH_DP is running in your system, which sends the alerts from RZ20 to SOST. If not schedule, please schedule the same and check after this job completion.
Thanks,

Hi
How can I configure Solution Manager to get
- Realtime Alerts
- Performance Metrics every 5 minutes
- Business Performance Metrics every 5 minutes
Can I have all the above data in CSV / HTML/ XML format
I have read the Solution Manager documentation, and it is cryptic for newbie starter
Any help or pointers to someone who has done this before, will be very valuable.

How do you get CCMS Alerts and E2E, can you elaborate or point me the steps/docs....
Thanks!

What will be the Upper Limits for Performance Metrics for Alerting

Hi,
We are planning to monitor the Performance of Cloud Services hosted onto Azure through VisualStudioOnline [TFS].
What will be the Upper limits for below metrics per cloud service hosted on Azure:-
CPU Percentage
Disk Read Bytes/Sec
Disk Write Bytes/Sec
Network In [Bytes/Sec]
Network Out [Bytes/Sec]
Thanks for the help.
Regards, Subhash Konduru

Hi,
An alert rule enables you to monitor a Azure service based on a metric value. When the value of a specified metric violates the threshold assigned for a rule, the alert rule becomes active and registers an alert.
To create an Alert Rule, you might want to check the below article
https://msdn.microsoft.com/en-us/library/azure/dn306638.aspx
To know more on the limits please follow the link

Hope this helps !

How to get low performances alert for Hyper-v Host ON scom

Hello Expert,
We have to implement a scenario VM Live migration which involved (SCOM,SCVMM,SCORCH Parts).
where SCOM parts will monitor the performances of SCVMM 's Hyper-V hosts and VMs running the within the Hyper-v hosts.
when the VMs utilization exceed the threshold and then scom monitor checks the performances of Running Hyper-v Hosts ,then using SCORCH automation ,VMs are moved to one of the best performances the Hyper-v hosts.
To implement this ,I have integrated SCOM 2012 R2 AND SCVMM 2012 R2 AND enabled the PRO Tips.
but don't know how to get alerts and configured related to performances of VMs and Hyper-v host.
What will be next needed to achieved this from SCOM PARTS.
Thanks and Regards
RICHA KM

Hi,
In addition, hope the management pack for Hyper-v 2012 can be helpful for you, please download and import it to your management group:

I keep getting a message saying Performance alert high memory usage by firefox what can I do about this. Patricia

I have gone into the History and deleted all the pages would this help reduce the memory usage.

Do a malware check with some malware scan programs.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of the database before doing a scan.<br />

I keep getting Norton 'performance alerts' that Firefox is using a lot of memory. Should I worry?

Is there some action I should take because of thes alaerts? It happens every time I start Firefox

This is likely coming from a third-party program. You can try to Reset Firefox. [[Reset Firefox – easily fix most problems]]

Display formatting of Metric / Stateless alerts

Hello together,
I'm writing a metric that checks (or rather uses a script to check) logfiles on the host. The script generates a unique key for each message so the oslinetoken fetchlet doesn't complain at multiple lines. This key should not be displayed in the EM console.
This is how it looks:
<Metric NAME="lfc_messages" TYPE="TABLE">
<Display>
<Label>Logfile check</Label>
</Display>
<TableDescriptor>
<ColumnDescriptor NAME="eventkey" TYPE="STRING" IS_KEY="TRUE" RENDERABLE="FALSE">
<Display FOR_SUMMARY_UI="FALSE">
<Label></Label>
</Display>
</ColumnDescriptor>
<ColumnDescriptor NAME="Result" TYPE="STRING" STATELESS_ALERTS="TRUE" IS_KEY="FALSE">
<Display FOR_SUMMARY_UI="TRUE">
<Label>Message String</Label>
</Display>
</ColumnDescriptor>
</TableDescriptor>
<QueryDescriptor FETCHLET_ID="OSLineToken">
<Property NAME="startsWith" SCOPE="GLOBAL">em_result=</Property>
<Property NAME="errStartsWith" SCOPE="GLOBAL">em_error=</Property>
<Property NAME="delimiter" SCOPE="GLOBAL">|</Property>
<Property NAME="command" SCOPE="GLOBAL">/u00/app/oracle/local/custom/bin/CheckMessages.sh</Property>
</QueryDescriptor>
</Metric>
I thought the RENDERABLE="FALSE" would prevent the key column from being shown, but that's not the case. When an error arises, it looks like this in the EM console:
The value of Result for 5fe5d2ef2cad76f87c6cb852c686a2f2 - is CRITICAL: Apr 30 09:15:09...
and 5fe5d2ef2cad76f87c6cb852c686a2f2 is the key column... Instead, I don't see the metric label "Logfile check" anywhere.
Another thing is, those are stateless alerts (as defined in above column descriptor attribute), so Enterprise Manager should not delete them by itself but give the user the possibility to do so, right?
The behaviour I experience is that in fact the user gets the possibility to clear the alert, but only until the collection runs next time. Then it will automatically be deleted by Enterprise Manager.
Can you please show me what's wrong with my code?
Thanks in advance,
Robert

Robert,
The console will absolutely display the key value. That's how it differentiates between different rows in a single result set. "Logfile check" is a larger bucket and wouldn't give enough specificity about what the alert was on.
Think about it this way. I have a Filesystems metric, with a mountPoint column and a pctFull column. mountPoint is the key, and I have many different mountPoints. I get an alert saying, "/x is 85% full." /x is just one of the mountPoints on the host. It wouldn't make sense to have an alert saying "Filesystems is 85% full," especially since it isn't true... it's only true of the one mountPoint.
You do have the power to change what the alert message looks like in the default collection file. Maybe that would help your problem?

User defined metrics for alert log errors

I want to create UDM for getting the full description of alert log ORA - error to be reported via E-mail. Can somebody guide me or help me withe script which can be used to create this alert. Currently, We get the only the message of that error is generated; which request us to manually check the alert to log to figure out the error.

Hi,
what metric did you use and what is the database version.
There are metrics related to alert log errors but those which have status at the end of a name return number of errors
and w/o status provide error description:
11g
Generic Incident - error message
Generic Incident Status - number of errors
10g
Generic Alert Log Error - error message
Generic Alert Log Error Status - number of errors
Did you set Generic Incident or Generic Alert Log Error? If description is not enough
you might use UDM but it would be easier for 11g since there are internal views which
have access to ADR, for 10g it will be required to build additional procedure (to open and read alert log)

Exporting SCOM Performance, Problem Alerts with PowerShell to CSV?

Is there a way to export System Center Operations Manger Performance and Problem Alerts to a CSV with the number of Counts and Milliseconds for the application that caused the issue?
When using System Center Operations Manager to gather performance events on applications, it would be nice to be able to export this data out to Excel.
Is there a PowerShell script that is available to export different event types? For example with for a performance alert or a problem alert, or highest usage.
Using System Center 2012 R2.
Thank you!
Jeff

Hi Jeff,
I dont have a powershell script , But surely have a SQL query which will pull the performance data from the operationsmanager DB.
Below is the one.
select Path, ObjectName, CounterName, InstanceName, SampleValue, TimeSampled
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where ObjectName = 'Memory' and CounterName = 'Available MBytes' and Path like '%Your Agent name%'
order by countername, timesampled
You will need to mention the Object name and counter for what you are looking for and in the path mention the agent name.
If you want the counter for all the agents then the Command should be altered as follows: Path like '%%'
'%%' - Represents that you want the perfmon data of the specific Object and counter on all the SCOM Agents.
===============================
==============================================
All perfmon data of all servers:
select Path, ObjectName, CounterName, InstanceName, SampleValue, TimeSampled
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where ObjectName LIKE '%%' and CounterName LIKE '%%' and Path like '%%'
order by countername, timesampled
====================================================
All perfmon data for only a specific agent:
select Path, ObjectName, CounterName, InstanceName, SampleValue, TimeSampled
from PerformanceDataAllView pdv with (NOLOCK)
inner join PerformanceCounterView pcv on pdv.performancesourceinternalid = pcv.performancesourceinternalid
inner join BaseManagedEntity bme on pcv.ManagedEntityId = bme.BaseManagedEntityId
where ObjectName LIKE '%%' and CounterName LIKE '%%' and Path like '%Your Agent name%'
order by countername, timesampled

Oracle Performance tunning genral question

Hi,
Below is the list of Areas of Oracle db for which tunning activities are done. You are invited to comment to it weather this is complete list or need some addition or deletion. As I'm learning PT for Oracle now a days, therefore I want to expand my knowledge by sharing what I'm learning and what I need to learn.
So comment with Open hearts on it. Espically from experts and Gurus.
Here is the List
1-Planning for Performance, include Storage consideration( Weather it is SAN, NAS, DAS), Network planning and host OS planning with proper configuration for running Oracle.
2-Database desining (Not under-Normalized and not Over-Normalized with proper usage of Indexes, views and Stored Procedures)
3- Instance tunning (Memory structure + B.g Processes)
4- Session tunning.
5- Segment Space tunning.
6- SQL tunning.
This is what uptill what I've learned. If it needs addition kindly tell me what are these. Please also provide me links(good and precise one) for PT tutorials on web.Also note that I'm discussing this w.r.t Single instance non-rac db.
Looking for Good sugessions
Regards,
Abbasi

Data Warehouse performance since changing retention settings?

Hi,
I dont know if its a coincidence but I have managed to get into a bit of a state with regard to our data warehouse.
Firstly when the server was specced I dont think anybody actually worked out what size the databases would work out to be. I have started troubleshooting initially because of a lack of disk space. The DW was set to the defaults of 400 days etc and had grown
to around 700GB. Our operations DB is around 50GB in size. The disk at this point had around 50GB of space left.
Anyway I did some work on the retention in the DW to knock a lot of stuff down to say 9 months as needed. A week later and the data is now 500GB although the physical size is still 700GB.
Now I dont know if its coincidence but in the last couple of days I am getting performance alerts such as not being able to store data in the DW in a timely manner, failing to perform maintenace and visual indications that things have slowed down on
the DW. For example an SLA report for the month for all servers now times out when before it ran in a few minutes.
So I am wondering if the "blank" space in the DW is now causing issues as there is data at both ends of the database perhaps. I would like to get this blank space back but no expert on SQL and wondering if any other considerations needs to be taken
for SCOM "to get this back".
I also understand that perhaps more disk space is required for the actual grooming so maybe I need to get down to 6 montghs of data before this can happen.
The performance part may not be tied to the issue but I guess either way I would like to get the space back if possible
thanks

There are sereval causes
1) check any events or performance collection which generate a hugh DB and DW size by using the following SQL query in
http://blogs.technet.com/b/kevinholman/archive/2007/10/18/useful-operations-manager-2007-sql-queries.aspx
2) You can also refer to the following post
http://deploymentportal.blogspot.ru/2012/08/operations-manager-data-warehouse.html
3) check SQL logs on the datawarehouse, especially for blocking problems
Also, check Disk IO on the data warehouse (the windows mp collects these metrics). If it affects all Management Servers and the message does say "timeout" then the problem is likely to be at the SQL end. It may not be maxed out by CPU or Memory but
there are likely to be other bottlenecks on the SQL box. What is the Disk Queue for disks that the operations manager data warehouse data and log files reside? These are on seperate physical disks aren't they??
My guess is that it is a SQL issue .... temporary timeouts suggest that SQL is busy doing something else. And I'd tend to concentrate my thoughts on Disk IO rather than memory or cpu.

Performance Manager LUN latency

Hello,Can you tell me if I can see LUN layer latency in OnCommand Performance Manager ? I can see the LUNs on volume but performance data seems to be gathered only on Volume level. Can I see it also on LUN level? And another question - is there any way to disable performance alerts until certain latency? F.e. I don't want to see alerts for 5ms latency especially as they are logged as critical. It really makes no sense so for the moment I have disabled all performance alerts.

Hi John, From the output you shared it looks like you using Performance Advisor and want to share a graph of a 7-mode system. The instructions link you shared is from Performance Manager which is for Clustered Data ONTAP only. In the Performance Advisor there is unfortunately no way to share a link. You can 'save as' to png as you probably already saw, or you can use the dfm CLI to generate the same and email, perhaps as a daily report. There is also a data collector that will post to the NetApp ToolChest that submits data to Graphite with dashboards in Grafana. This solution would allow sharing of a URL like you desire. If you want more info on this let me know. Kind Regards,Chris MaddenStorage Architect, NetApp

Poor Security Metrics and none policies for Sybase Plugin

Hi.
I found out that the Sybase Plugin for Grid Control is mostly focused on performance metrics and alerts and I need a more deep intrusion on security matters.
How can I create metrics or policies for Sybase Targets? or if not, would it be considered on future versions??
Thanks

Downgrade your routers firmware to the last known working version by going here. Now give it a try.

Oracle Alert not working on Oracle e-Business Suite 11.5.10

Dear All,
Oracle Alert was working on Oracle e-Business Suite 11.5.10 with Postfix server. But now
we changed to MS exchange server instead of postfix server then onwards the alert is not working. I done the configuration according to MS Exchange server, inbound/outbound Server Name/reply-to-Address/added relay host.
Test Notification Mailer is working fine, but the alert is not working.
please anyone help me on this.
regards,
sva

Hi Hussien,
I done the diagnostic test got this warning
WARNING - The profile option 'RESP_ID' does not exist
ACTION - Set the 'RESP_ID' profile option. Consult Oracle Alert user guide for more details on this profile option.
WARNING - The profile option 'EMAIL_ADDRESS' does not exist
ACTION - To use the 'EMAIL_ADDRESS' profile option value as the :MAILID value, it must be created and set as the 'EMAIL_ADDRESS' profile option and perform some additional setup steps. Please consult Oracle Alert user guide for more details. If the 'EMAIL_ADDRESS' profile option has not been created, or if its value is null, Oracle Alert uses the operating system userid or the application username of the user who triggered the event, depending on the value set for the 'Default User Mail Account' option in the Oracle Alert Options form.
When I done the oracle alert test it completed with normal. but not sending the mail.
