Exadata Performance Monitoring Part 1

CELLCLI LIST command can be used to monitor and monitor cell performance metrics

To receive some help on specific performance metric, use

list metricdefinition <metric_name> DETAIL

For Example:

CellCLI> list metricdefinition Io_LOAD DETAIL
         name:                   IO_LOAD
         description:            "Average I/O load for hard disks"
         metricType:             Instantaneous
         objectType:             CELL
         unit:                   Number

To display specific metric value, use:

CellCLI> LIST METRICCURRENT CL_CPUT DETAIL
         name:                   CL_CPUT
         alertState:             normal
         collectionTime:         2011-02-17T00:39:32-08:00
         metricObjectName:       cell
         metricType:             Instantaneous
         metricValue:            30.6 %
         objectType:             CELL
LIST command also accepts where clause (attribute filters):

To Show all immediate non-zero performance metric values:

LIST METRICCURRENT where metricValue > 0

CD_IO_TM_R_LG   CD_disk02_cell                                  36,321 us
CD_IO_TM_R_SM   CD_disk01_cell                                  1,347,527 us
CD_IO_TM_R_SM   CD_disk02_cell                                  1,151,048 us
CD_IO_TM_R_SM   CD_disk03_cell                                  931,721 us
CD_IO_TM_R_SM   CD_disk04_cell                                  2,286,866 us
CD_IO_TM_R_SM   CD_disk05_cell                                  958,574 us

To show historical data, use LIST METRICHISTORY Command:

You can use metricobjectname to show specific disk and collectiontime to show specific timeframe.

Make sure to filter data as default "list metrichistory" would provide too much data to comprehend

CellCLI> list metrichistory CD_IO_RQ_W_SM where metricobjectname = CD_disk01_cell and collectiontime > '2011-02-17T00:53:01-08:00' and metricvalue > 0

CD_IO_RQ_W_SM   CD_disk01_cell  350,071 IO requests  2011-02-17T00:53:19-08:00
CD_IO_RQ_W_SM   CD_disk01_cell  356,091 IO requests  2011-02-17T00:54:19-08:00
CD_IO_RQ_W_SM   CD_disk01_cell  358,111 IO requests  2011-02-17T00:55:19-08:00
CD_IO_RQ_W_SM   CD_disk01_cell  381,131 IO requests  2011-02-17T00:56:19-08:00
CD_IO_RQ_W_SM   CD_disk01_cell  454,151 IO requests  2011-02-17T00:57:19-08:00
CD_IO_RQ_W_SM   CD_disk01_cell  470,171 IO requests  2011-02-17T00:58:19-08:00
CD_IO_RQ_W_SM   CD_disk01_cell  640,191 IO requests  2011-02-17T00:59:20-08:00
CD_IO_RQ_W_SM   CD_disk01_cell  850,211 IO requests  2011-02-17T01:00:20-08:00

Blog monetization - some thoughts

Since I enabled AdSense on my blog I started to look for what monetization of the blog is. To my surprise, this is a huge industry and it is not based on generation of my money just by creation of a good content.

My "simple minded" understanding of how people earning money on blogs was that one who creates good content, brings more visitors. These visitors suppose to "produce" some clicks on AsSense; at some point this "clickng" would translate into nice check once in a while.

Not that simple - first, there is a "blogsphere war" around - some people prefer blogspot, and some rave about wordpress. Monetization gurus warn about using blogspot, as at some point, it prevents blog owner from converting his blog into "lean, mean money making machine" - which brings in question point - why to make blog to begin with? - to express yourself or to make money? If blog is done just for money - this is garbage content with no spirit and no true continuity, and this garbage will saturate search engines and will only hide good information from people who need it.

I think it should be a matter of balance - it is understandable, that people love rewards and for many monetization is not about money, but rather seeing that their work is been rewarded, may be not in direct way, but a very "real" way.

When you look around - you see tons of advertised blog software and portals that for some "small" money will post your blog information around tons of other blogs, etc. There is other software that will generate dozens (or more) blogs for you with the questionable content  (from a copyright perspective) and, again, will supposedly generate money for you.

First I was quite shocked. Does this blogging bacchanalia means that normal blogger, who just writes really good and authentic stuff, has almost zero chances to be heard, unless he joins money making and content faking crowd?

I just touched this topic - may be I wrong, most probably I need to learn much more about the subject - this is quite interesting phenomena.

Overall - we need better "google", better search engines - we need TRUTH SEARCH ENGINES, We need technology that will identify truth and real, good information and will spit all the junk to where it belongs - garbage bin of search engines, not our screens

Surprisingly, I came to this conclusion and that was not my intention at the beginning when I start writing this piece (Honest!)

SQLS*Plus/SQLSPlus - SQL*Plus for SQL Server

IMHO this is a very useful application:

SQLS*Plus for SQL Server (http://www.memfix.com/)

When working with SQL Server and trying to use "sqlcmd", it is always coming to mind, that Oracle SQL*Plus is the best database command line application and it would be great to have one for SQL Server - so SQLS*Plus is exactly what is needed.
