Active IP Sensor Enterprise
v2.0.0. BETA
Active IP
Sensor v1.7.4 (7-May-2007)
Theory
of Operation
o
Active IP Sensor is non-intrusive. It
issues dynamic scripts and creates local file system objects in order to
implement a communication pipe to send commands and get their outputs or
status. There are no ports opened or any connections made by Active IP
Sensor. It simply parses the script output (the tree view) and
writes the results in a file (Listen/Record mode).
o
The scripts pipe their output to text files.
Active IP Sensor parses this text file to get the needed output. The
last message written by a script to a text file is an END OF
PROCESSING token. Active IP Sensor monitors these text
files for the appearance of this token with a timeout (currently 64 seconds).
This allows asynchronous scripts to inform Active IP Sensor when
they have completed and permits Active IP Sensor to form
synchronous, serial data sources from them. This sort of buffering is most
evident while streaming trace route outputs, which are
inherently asynchronous but asynchronous streaming is the dominant
theme throughout Active IP Sensor and is used to:
o
Issue high latency queries across
networks.
o Listen
for real time remote Active IP Sensor Recordings.
o Find
Local IP processes and their run time components.
All are
examples of different asynchronous requirements in Active IP Sensor
each with unique streaming characteristics. Yet, they are all
implemented using nothing more than simple scripts, text files and a few
timers. Active IP Sensor does this to avoid introducing any IP
artifacts while sensing IP port activity and to ensure the broadest
range of run time environments for Active IP Sensor to operate
in.
o
Active IP Sensor streams the results
from command scripts to a dynamic tree view after they have completed. This
serializes the update interval timer against environment latencies (it must
wait until the environment executes a command script).
o
After parsing a command script, all
the nodes in the Tree view are first given a tag that signifies them as
stale. Tree view updates from the command script are accompanied with a tag
that signifies that a node is being added or updated. Those nodes that
remain are reaped leaving only nodes that represent the current
sample.
o Many
concurrent writers and listeners of Active IP Sensor history files
are all taking advantage of each other`s inherent latencies while
they flush their file I/O and go after their next sample (during this
period, the file is available!)
|
V1.7.4
(07-May-2007)
|
o
Added Unattended Data Collection mode.
o
Fixed many bugs while recording/listening to history files.
o
Active IP Sensor has surpassed Remote Batch Copy as Morning Glory
Technologies Most Downloaded
Product.
|
|
V1.6.7 (08-Apr-2007)
|
o
Use html instead of RTF for ActiveIPSensorLog.html
o
Embedded web browser.
o
Misc bug fixes.
|
|
V1.5.3
(04-Mar-2007)
|
o
All messages are now thru an
asynchronous RTF stream (no more message forms or Command
boxes). More importantly, processes that emit asynchronous text streams
are buffered much more reliably thru the RTF stream then before.
o
Better asynchronous stream management.
|
|
V1.4.7 (02-Mar-2007)
|
o Flush file I/O before
writing headers/delta. This seems to have fixed many intermittent
anomalies while listening to Snapshot mode recordings.
|
|
|
o Web
Help brought the user to Remote Batch Copy support page.
|
|
V1.4.6
(01-Mar-2007)
|
o
Record/Open Active IP Sensor background colors.
|
|
V1.4.5 (23-Feb-2007)
|
o Only save samples in history files if they have
changed from the previous.
|
|
o Make IP Tree code more self-contained. It will
be used later.
|
|
V1.4.0
(05-Feb-2007)
|
o
Added Protocol counters and stats.
|
|
V1.0.0
(28-Jan-2007)
|
o
Initial Check
in.
|
o
There will soon be a demo able, registered version
available at a very low price
with literally dozens of new features (48+). Most of the planned new
features are not possible with any other product.
In keeping with our core business philosophy,
many will involve new techniques never before imagined.
Check with us later this summer for more details. If you would like to
