I have some old "cyberspace situational awareness" PHP code I used for a visualization project a few years ago, which captures and stores details information on web session activity; this code has proven handy identifying rouge bots in the past.
So, I have modified that code to capture and store detailed session information, including the number of hits per IP address, the user agent string, country code, etc. when the 1 minute load average is above 20 and less than 50.
So, let's see what happens the next time we get a spike... this should be interesting.
we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)
Hello all, I have a question about load averages.
I've read the man pages for the uptime and w command for two or three different flavors of Unix (Red Hat, Tru64, Solaris). All of them agree that in the output of the 2 aforementioned commands, you are given the load average for the box, but... (3 Replies)
Hello, Here is the output of top command. My understanding here is,
the load average 0.03 in last 1 min, 0.02 is in last 5 min, 0.00 is in last 15 min.
By seeing this load average, When can we say that, the system load averge is too high?
When can we say that, load average is medium/low??... (8 Replies)

Hi ,
I am using 48 CPU sunOS server at my work.
The application has facility to check the current load average before starting a new process to control the load.
Right now it is configured as 48. So it does mean that each CPU can take maximum one proces and no processe is waiting.

Hi,
I am getting a high load average, around 7, once an hour. It last for about 4 minutes and makes things fairly unusable for this time.
How do I find out what is using this. Looking at top the only thing running at the time is md5sum.
I have looked at the crontab and there is nothing... (10 Replies)

finance::beancounter
BeanCounter(3pm) User Contributed Perl Documentation BeanCounter(3pm)NAME
Finance::BeanCounter - Module for stock portfolio performance functions.
SYNOPSIS
use Finance::BeanCounter;
DESCRIPTION
Finance::BeanCounter provides functions to download, store and analyse stock market data.
Downloads are available of current (or rather: 15 or 20 minute-delayed) price and company data as well as of historical price data. Both
forms can be stored in an SQL database (for which we currently default to PostgreSQL though MySQL is supported as well; furthermore any
database reachable by means of an ODBC connection should work).
Analysis currently consists of performance and risk analysis. Performance reports comprise a profit-and-loss (or 'p/l' in the lingo) report
which can be run over arbitrary time intervals such as "--prevdate 'friday six months ago' --date 'yesterday'" -- in essence, whatever the
wonderful Date::Manip module understands -- as well as dayendreport which defaults to changes in the last trading day. A risk report show
parametric and non-parametric value-at-risk (VaR) estimates.
Most available functionality is also provided in the reference implementation beancounter, a convenient command-line script.
The API might change and evolve over time. The low version number really means to say that the code is not in its final form yet, but it
has been in use for well over four years.
More documentation is in the Perl source code.
DATABASE LAYOUT
The easiest way to see the table design is to look at the content of the setup_beancounter script. It creates the five tables stockinfo,
stockprices, fxprices, portfolio and indices. Note also that is supports the creation of database for both PostgreSQL and MySQL.
THE STOCKINFO TABLE
The stockinfo table contains general (non-price) information and is index by symbol:
symbol varchar(12) not null,
name varchar(64) not null,
exchange varchar(16) not null,
capitalisation float4,
low_52weeks float4,
high_52weeks float4,
earnings float4,
dividend float4,
p_e_ratio float4,
avg_volume int4
This table is updated by overwriting the previous content.
THE STOCKPRICES TABLE
The stockprices table contains (daily) price and volume information. It is indexed by both date and symbol:
symbol varchar(12) not null,
date date,
previous_close float4,
day_open float4,
day_low float4,
day_high float4,
day_close float4,
day_change float4,
bid float4,
ask float4,
volume int4
During updates, information is appended to this table.
THE FXPRICES TABLE
The fxprices table contains (daily) foreign exchange rates. It can be used to calculate home market values of foreign stocks:
currency varchar(12) not null,
date date,
previous_close float4,
day_open float4,
day_low float4,
day_high float4,
day_close float4,
day_change float4
Similar to the stockprices table, it is index on date and symbol.
THE STOCKPORTFOLIO TABLE
The portfolio table contains contains the holdings information:
symbol varchar(16) not null,
shares float4,
currency varchar(12),
type varchar(16),
owner varchar(16),
cost float(4),
date date
It is indexed on symbol,owner,date.
THE INDICES TABLE
The indices table links a stock symbol with one or several market indices:
symbol varchar(12) not null,
stockindex varchar(12) not null
BUGS
Finance::BeanCounter and beancounter are so fresh that there are only missing features :)
On a more serious note, this code (or its earlier predecessors) have been in use since the fall of 1998.
Known bugs or limitations are documented in TODO file in the source package.
