CPU Utilization check

Hello,
I have a situation where the oracle CPU spikes upto 99% ( avg about 50-60 %) during a specific period (about 3-4 hrs ) every day. As a result of this the entire application slows down. We are not running any additional processes (related to application) nor user load is incresed in this period. I would like to find out what processes are consuming so much of CPU.
Does anybody know how to find out more about processes/queries that are using more resources/CPUs?
TIA

Hi,
I would like to find out what processes are consuming so much of CPU. This "ps" command works great for me:
Display top CPU consumers with ps
The following command can be used to display the top CPU consumers on any UNIX server. Note that the sort +6 command displays the CPU column. This is because the ps columns are counted from left-to-right, with the first column being column zero.
root> ps -ef|sort +6|tail
root 512 1 0 Aug 10 ? 0:53 /usr/lib/osa/bin/arraymon
root 460 1 0 Aug 10 ? 1:22 /usr/sbin/cron
root 1 0 0 Aug 10 ? 2:26 /etc/init -
root 565 1 0 Aug 10 ? 6:12 /usr/bin/perl /pixlog.pl
root 471 1 0 Aug 10 ? 9:10 /usr/sbin/nscd
netsaint 765 1 0 Aug 10 ? 27:16 helpdesk/netsaint.cfg
root 742 572 0 Aug 10 ? 32:04 opt/VRTSvmsa
root 454 1 0 Aug 10 ? 44:09 /usr/sbin/syslogd
root 3 0 0 Aug 10 ? 363:12 fsflush
Here we see the tasks in order of their total CPU consumption, with the largest value at the end of the list. In cases where a process has been running for more than one day, the display format changes. In these cases, the time format changes and column 5 is the CPU column.
root> ps -ef|sort +5|tail
root 5440 2094 0 Nov 21 - 0:47 /usr/sbin/syslogd
root 9244 1 0 Nov 21 - 3:26 ./pdimapsvr.ip -D0
root 10782 1 0 Nov 21 - 4:41 ./pdiconsvr.ip -D0
root 5990 2094 0 Nov 21 - 5:33 /usr/sbin/snmpd
root 4312 1 0 Nov 21 - 7:14 /usr/sbin/cron
root 4448 2094 0 Nov 21 - 9:25 /usr/sbin/rwhod
root 1 0 0 Nov 21 - 198:59 /etc/init
root 2450 1 0 Nov 21 - 438:30 /usr/sbin/syncd 60
Using ps auxgw command in HP/UX and AIX
Another approach to finding top CPU consumers on your UNIX server is to use the ps auxgw command. The third column of this listing (%CPU) shows the percentage of CPU used. Hence, the following command will display the top CPU users:
root> ps auxgw|sort +2|tail
oracle 14922 0.6 1.0 8300 5720 - A 01:01:46 2:57 oracleprod
oracle 22424 0.6 1.0 8328 6076 - A 07:48:43 0:21 oracleprod

How to check CPU % Utilization with SNMP

We are using Ipswitch's What's Up Professional 2006 to monitor devices on our network. Their default snmp graphing utilities use the HOST RESOURCES MIB to collect and graph system performance statistics over time. I have them running perfectly on all my Windows servers, but for my Solaris systems I am only able to retrieve Memory, Disk, and Network Interface statistics. The CPU monitor is unable to retrieve data from our Solaris systems. A typical system is running Solaris 10 with the default agent, NET-SNMP version 5.0.x. Does anyone know if the default agent supports checking CPU usage in the HOST RESOURCES MIB? If not can anyone point me to a different MIB & instance that will return % CPU utilization of a Solaris 10 server? Any input would be greatly appreciated. I've searched everywhere for the solution but I am unable to find any straight-forward answers, hopefully someone can help.

Are there any specific tests, or logs prior to isolate this issue?

Hi,
A few points:
> Use one of the recommended OVA templates
> Check if the spike is random or occurs at a specific time. If it occurs at a specific time it could be coinciding with something like DRS backup, CDR load, busy hours etc.
> Minimum set of logs needed for one such high CPU spike instance are:
Detailed ccm traces from all nodes
RisDC Perfmon logs
Proglogs
Also, capture the output of the following:

Performance degrading CPU utilization 100%

Hello,
RHEL 4
Oracle 10.2.0.4
Attached to a DAS (partition is 91% full) RAID 5
Over the past few weeks my production database performance has majorly degraded. I have not made any application, OS, or database changes (I was on vacation!). I have started troubleshooting, but need some more tips as to what else I can check.
My users run a query against the database, and for a table with only 40,000 rows, it will take about 2 minutes before the results return. For a table with 12 million records, it takes about 10 minutes or more for the query to complete. If I run a script that counts/displays a total record count for each table in the database as well as a total count of all records in the database (~15,000,000 records total), the script either takes about 45 minutes to complete or sometimes it just never completes. The Linux partition on my DAS is currently 91% full. I do not have Flashback or auditing enabled.
These are some things I tried/observed:
I shut down all applications/servers/connections to the database and then restarted the database. After starting the database, I monitored the DAS interface, and the CPU utilization spiked to 100% and never goes down, even with no users/application trying to connect to the database. The alert.log file contains these errors:
ORA-00603: ORACLE server session terminated by fatal error
ORA-00600: internal error code arguments: [ttcdrv-recursivecall]
ORA-03135: connection lost contact
ORA-06512: at "CTXSYS.SYNCRN", line 1
The database still starts, but the performance is bad. From the error above and after checking performance in EM, I see there are a lot of sync index jobs running by each of the schemas and the db sequential file read is high. There is a job to resync the indexes every 5 minutes. I am going to try disabling these jobs tihs afternoon to see what happens with the CPU utilization. If it helps, I will try adjusting the job from running every 5 minutes to something like every 30 minutes. Is there a way to defrag the CONTEXT indexes? REBUILD?
I'm not sure if I am running down the right path or not. Does anyone have any other suggestions as to what I can check? My SGA_TARGET is currently set to 880M and the SGA_MAX_SIZE is 2032M. Would it also help for me to increase the SGA_TARGET to the SGA_MAX_SIZE; thus increasing the amount of space allocated to the buffer cache? I have ASMM enabled and currently this is what is allocated:
Shared Pool = 18.2%
Buffer Cache = 61.8%
Large Pool = 16.4%
Java Pool = 1.8%
Other = 1.8%
I also ran ADDM and these were the results of my Performance Analysis:
34.7% The throughput of the I/O subsystem was significantly lower than expected (when I clicked on this it said to either implement ASM or stripe using SAME methodology...we are already using RAID5)
31% SQL statements consuming significant database time were found (I cannot make application code changes, and my database consists entirely of INSERT statements...there are never any deletes or updates. I see that the updates that are being made were by the index resyncing job to the various DR$ tables)
18% Individual database segments responsible for significant user I/O wait were found
15.9% Individual SQL statements responsible for significant user I/O wait were found
8.4% PL/SQL execution consumed significant database time
I also recently ran a SHRINK on all possible tablespace as recommended in EM, but that did not seem to help either.
Please let me know if I can provide any other pertinent information to solve the poor I/O problem. I am leaning toward thinking it has to do with the index sync job stepping on itself...the job cannot complete in 5 minutes before it tries to kick off again...but I could be completely wrong! What else can I check to figure out why I have 100% CPU utilization, with no users/applications connected? Thank you!
Mimi
Edited by: Mimi Miami on Jul 25, 2009 10:22 AM

Tables/Indexes last analyzed today.
I figured out that it was the Oracle Text indexes synching to frequently that was causing the problem. I disabled all the jobs that kicked off those indexes and my CPU utilization dropped to almost 0%. I will work on tuning the interval/re-enabling the indexes for my dynamic datasources.
Thank you for everyone's suggestions!

How to measure CPU utilization from Oracle AWR

Hi All,
How to measure the cpu usage % from the AWR reports.
Oracle : 10.2.0.3
OS : AIX 5300-12-02
I see the top 5 waited events listing CPU time in it.
Top 5 Timed Events Avg %Total
~~~~~~~~~~~~~~~~~~ wait Call
Event Waits Time (s) (ms) Time Wait Class
CPU time 98,655 40.0
Is it mean that the CPU utilization is full to its 100%. Is there any other way to measure how much an oracle instance is utilizing the CPU ?
Please advice.
TIA,

Snmp alerts for CPU utilization

Hi,
I want to enable snmp alerts on l2 and l3 switches to monitor CPU utilization.
I have Opmanager which is acting as SNMP server.
I have switches L2 and L3 which are running IOS 12.0, 12.1, 12.2
Do all these IOS versions support SNMP alerts?
And also I want to know the commands to be configured on switches for this.
Regards
skrao

You can configure SNMP traps for CPU Thresholding Notification.
http://www.cisco.com/en/US/products/ps6350/products_configuration_guide_chapter09186a0080455772.html
You should be ok with the versions you list but check exact IOS version supports it at http://www.cisco.com/go/fn
If you do not want to use traps then there are specific oids that can be polled for 1minute average (1.3.6.1.4.1.9.2.1.57) and also 5 minute average (1.3.6.1.4.1.9.2.1.58). I've used these in the past with no problems. These oids may have been superceeded so check for latest. You can always snmpwalk a device to check oids.
The cisco SNMP navigator is helpful when it comes to oids.
http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en
If you haven't got any SNMP configured yet on the switch check out http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Network%20Infrastructure&topic=Network%20Management&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddb4e54

ST06 is showing a Application server CPU usage.
If your thinking that it should be higher you might check the saposcol release level.
If your looking for DB server CPU then you will need ST07 if sapcl and things are configured correctly.
Or get the system Z team to look at usage in RMF reports for given time interval.
The system CPU usage can be seen for history in st07n history section if you want to see usage over say last 24-36 hours

Low CPU utilization on Solaris

Hi all.
We've recently been performance tuning our java application running
inside of an Application Server with Java 1.3.1 Hotspot -server. We've
begun to notice some odd trends and were curious if anyone else out
there has seen similiar things.
Performance numbers show that our server runs twice
as fast on Intel with Win2K than on an Ultra60 with Solaris 2.8.
Here's the hardware information:
Intel -> 2 processors (32bit) at 867 MHz and 2 Gig RAM
Solaris -> 2 processors (64bit) at 450 MHz and 2 Gig RAM.
Throughput for most use cases in a low number of threads is twice as
fast on Intel. The only exception is some of our use-cases that are
heavily dependent on a stored procedure which runs twice as fast on
Solaris. The database (oracle 8i) and the app server run on the same
machine in these tests.
There should minor (or no) network traffic. GC does not seem to be an
issue. We set the max heap at 1024 MG. We tried the various solaris
threading models as recommended, but they have accomplished little.
It is possible our Solaris machine is not configured properly in some
way.
My question (after all that ...) is whether this seems normal to
anyone? Should throughput be higher since the processors are faster on
the wIntel box? Does the fact that the solaris processors are 64bit
have any benefit?
We have also run the HeapTest recommended on this site on both
machines. We found that the memory test performs twice as fast on
solaris, but the CPU test performs 4 times as slow on solaris. The
"joint" test performs twice as slow on solaris. Does this imply bad
things about our solaris configuration? Or is this a normal result?
Another big difference is between Solaris and Win2K in these runs is
that CPU Utilization is low on solaris (20-30%) while its much higher
on Win2K (60-70%)
[both machines are 2 processor and the tests are "primarily" single
threaded at
this stage]. I would except the solaris CPU utilization to be around
50% as well. Any ideas why it isn't?

Hi,
I recently went down this path and wound up coming to the realization that the
cpu's are almost neck and neck per cycle when running my Java app. Let me qualify
this a little more (400mhz Sparc II cpu vs 500mhz Intel cpu) under similar load
running the same test gave me similar results. It wasn't as huge difference in
performance as I was expecting.
My theory is given the scalability of the SPARC architecture, more chips==more
performance with less hardware, whereas the Wintel boxes are cheaper, but in order
to get scaling, the underlying hardware comes into question. (how many wintel
boxes to cluster, co-locate, manage, etc…)
From what little I've found out when running tests against our Solaris 8 (E-250's)
400mhz UltraSparc 2's is that it appears that the CPU performance in a lightly
threaded environment is almost 1 cycle / 1 cycle (SPARC to Intel). I don't think
the 64 bit SPARC architecture will buy you anything for java 1.3.1, but if your
application has some huge memory requirements, then using 1.4.0(when BEA supports
it) should be beneficial (check out http://java.sun.com/j2se/1.4/performance.guide.html).
If your application is running only a few threads, tying the threads to the LWP
kernel processes probably won't gain you much. I noticed that it decreased performance
for a test with only a few threads.
I can't give you a good reason as to why your Solaris CPU utilization is so low,
you may want to try getting a copy of Jprobe and profiling Weblogic and your application
to see where your bottlenecks are. I was able to do this with our product, and
found some nasty little performance bugs, but even with that our CPU utilization
was around 98% on a single and 50% on a dual.
Also, take a look at iostat / vmstat and see if your system is bottlenecking doing
io operations. I kept a background process of vmstat to a log and then looked
at it after my test and saw that my cpu was constantly pegged out (doing a lot
of context switching), but that it wasn't doing a whole lot of page faults
(had enough memory).
If you're doing a lot of serialization, that could explain slow performance as
well.
I did follow a suggestion on this board of running my test several times with
the optimizer (-server) and it boosted performance on each iteration until a plateau
on or about the 3rd test.
If you're running Oracle or another RDBMS on your Solaris machine you should see
a pretty decent performance benchmark against NT as these types of applications
are more geared toward the SPARC architecture. From what I've seen running Oracle
on Solaris is pretty darn fast when compared to Intel.
I know that I tried a lot of different tweaks on my Solaris configuration (tcp
buffer size, etc/system parameters for file descriptors, etc.) I even got to the
point where I wanted
to see how WebLogic was handling the Nagle algorithm as far as it's POSIX muxer
was concerned and ran a little test to see how they were setting the sockets (setTcpNoDelay(Boolean)
on java.net.Socket). They're disabling the Nagle algorithm so that wasn't an
issue sigh. My best advice would be to profile your application and see where
the bottlenecks are, you might be able to increase performance, but I'm not too
sure. I also checked out www.spec.org and saw some of their benchmarks that
coincide with our findings.
Best of luck to you and I hope this helps :)

Hi all.
We've recently been performance tuning our java application running
inside of an Application Server with Java 1.3.1 Hotspot -server. We've
begun to notice some odd trends and were curious if anyone else out
there has seen similiar things.
Performance numbers show that our server runs twice
as fast on Intel with Win2K than on an Ultra60 with Solaris 2.8.
Here's the hardware information:
Intel -> 2 processors (32bit) at 867 MHz and 2 Gig RAM
Solaris -> 2 processors (64bit) at 450 MHz and 2 Gig RAM.
Throughput for most use cases in a low number of threads is twice as
fast on Intel. The only exception is some of our use-cases that are
heavily dependent on a stored procedure which runs twice as fast on
Solaris. The database (oracle 8i) and the app server run on the same
machine in these tests.
There should minor (or no) network traffic. GC does not seem to be an
issue. We set the max heap at 1024 MG. We tried the various solaris
threading models as recommended, but they have accomplished little.
It is possible our Solaris machine is not configured properly in some
way.
My question (after all that ...) is whether this seems normal to
anyone? Should throughput be higher since the processors are faster on
the wIntel box? Does the fact that the solaris processors are 64bit
have any benefit?
We have also run the HeapTest recommended on this site on both

Ironport C360 Cpu Utilization is 99 %

                   Hi All,
In a Ironport C360 Email Security Appliance , i am getting 99% cpu usage, pl suggest how to resolve it.
Email Security Appliance:
94.0%
Anti-Spam:
2.0%
Anti-Virus:
0.0%
Reporting:
1.0%
Quarantine:
0.0%
Total CPU Utilization:
99.0%
Regards

Hello Amit,
this is obviously an internal process consuming all the CPU power, as Jamie already pointed out restarting the appliance may fix the problem, however before doing that you could open a support request have customer support look into that, to make sure not to whipe out any traces. You might also check the following things:
GUI: Monitor->System Capacity->Incoming Mail   Is the traffic or the number of concurrent connections always high? In this case there might be a capacity problem
CLI: status detail      Are there a lot of messages in the quarantine (several 10.000)? Lots of active recipients? May indicate a problem with the internal database or reporting.
A stuck database or workque process would go away after a reboot, a capacity problem, however, won't.
