Just noticed, after digging around in the DB logs from my MQTT instrumentation, that the last spike correlated with a jump in data transferred out of the network interface:
Typical values are much less (see below), so this would seem to validate the "rouge bots hypothesis", currently leading the candidate to explain these periodic spikes:
This is also the first "hard correlation" of a spike with network interface iostats, so, let's see if my code in the post before this one will trap the next big spike
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 have installed solaris 10 on t-5120 sparc enterprise.
I am little surprised to see load average of 2 or around on this OS.
when checked with ps command following process is using highest CPU. looks like it is running for long time and does not want to stop, but I do not know... (5 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)

Font::TTF::GDEF - Opentype GDEF table support
DESCRIPTION
The GDEF table contains various global lists of information which are apparantly used in other places in an OpenType renderer. But
precisely where is open to speculation...
INSTANCE VARIABLES
There are up to 5 tables in the GDEF table, each with their own structure:
GLYPH
This is an Font::TTF::Coverage Class Definition table containing information as to what type each glyph is.
ATTACH
The attach table consists of a coverage table and then attachment points for each glyph in the coverage table:
COVERAGE
This is a coverage table
POINTS This is an array of point elements. Each element is an array of curve points corresponding to the attachment points on that
glyph. The order of the curve points in the array corresponds to the attachment point number specified in the MARKS coverage
table (see below).
LIG This contains the ligature caret positioning information for ligature glyphs
COVERAGE
A coverage table to say which glyphs are ligatures
LIGS An array of elements for each ligature. Each element is an array of information for each caret position in the ligature (there
being number of components - 1 of these, generally)
FMT This is the format of the information and is important to provide the semantics for the value. This value must be
set correctly before output
VAL The value which has meaning according to FMT
DEVICE For FMT = 3, a device table is also referenced which is stored here
MARKS
This class definition table defines the classes of mark glyphs that can be selected for processing using the MarkAttachmentType field
of lookup FLAG words.
MARKSETS
Contains an array of coverage tables indexed by the FILTER value of a lookup.
METHODS
$t->read
Reads the table into the data structure
$t->out($fh)
Writes out this table.
$t->update
Sort COVERAGE tables.
