Subject: Metrics on Windows XP
Message-ID: <1dd8f11e0707110843u5618152csfcb496c221ff86fe@mail.gmail.com>

Hello,

I'm a new Cougaar developper.

I want to know if the metric service can bring me informations about the
computer in general.
  For example, I need the CPU usage of the computer in general (not only the
CPU usage of an agent or a node, or the jvm).

Then, the feature must run on Windows XP.
  And I get "WARN [DirectSysStatSupplier] - No handler for CPU on platform
Windows XP", which makes me think it won't work on Windows.

That's why I want to add new metrics, based on native calls.
So I read the documentation at "
http://cougaar.cougaar.org/software/12.2/OnlineManual/MetricsService/", in
particular the section "Add New Metric".
I look at an exemple of sensor plugin : "
org.cougaar.core.thread.AgentLoadSensorPlugin".
But this sensor get it's values suscribing to the metric service, and there
is no metric which can answer my need : Get the global CPU usage on Windows
plateform.

Finaly, I look at the "Use Cases and Examples", in particular the "Example
Metrics Writer", in order to be able to add my own key.
When I add a new key, like the "Example Metrics Writer" do with the
"Current_Time_Millis" key ; I can't get the value after, because I don't
know the path.
For example, I manage to modify an existing key, like "Host_[Host
IP]_CPU_Jips", and get my funny value after because I know the path is
"Host([Host IP]):Jips".
So where can I do the mapping between key and path ? Because the example
shows how can I put a key, but not how can I put the path.

Guillaume,

The Host metrics come from a metric service via the SysStat "Data  
Feed", which periodically polls the host OS for system metrics.
For linux this is easy using the /proc file interface.
For Solaris and MacOS we can get the load average by executing the  
program "uptime"
For Windows nothing is easy, (at least for us). We attempted using  
JNI to make Windows system calls, but abandoned that code as unreliable.

If you know of a way to get at Windows OS parameters from java,  
without JNI calls please tell us we can add these calls.  I.E. is  
there a program that we can exec, that is always installed in  
Windows? If you have working JNI code we might look at, but no  
promises. DLL's are a configuration nightmare.

Specifically, we would like to fill in the metrics servlet table  
"$<NODE1>/metrics/resources"
or the Metrics Host Keys
  http://cougaar.cougaar.org/software/latest/doc/OnlineManual/ 
MetricsService/keys.html

The missing metrics are:
LoadAverage (this is the key metric, but Windows does not seem to use  
Load Average (Average number of jobs ready to run).
Cache
TcpInUse
UdpInUse
TotalMemory
FreeMemory

Windows metrics that cougaar currently measures.
Count is obtained via Java System calls
JIPS (Java Instructions per second) is obtained via a micro benchmark  
when the node first starts up.

BTW: You could not find these metrics in the Cougaar code because,  
the Metric Service implementation really is the QuO Resource Status  
Service (quo.bbn.com), so the source code is not available via  
cougaar.org. We are debating on whether to add the QuO RSS source  
code to cougaar. Adding Windows support may be a good excuse to do  
this branch.

Hello John,

Thank you for your fast answer.

I work on finding a good method to get windows metric.
Because we need to get global CPU usage, memory usage, and network usage, on
Windows XP and Windows Vista.

Then, we want to add metric in the Metric Service implementation.
So, if you open the source, we will propose to adapt the framework to allows
developers to add new metrics easily (if it isn't already done).

There are a bunch of options for getting raw metrics VALUES into the  
metrics service.
1) The most convenient way is to publish the "Key" into the  
MetricUpdaterService.
  http://cougaar.cougaar.org/software/latest/doc/OnlineManual/ 
MetricsService/MetricsUpdateService.html

2) You could also add startup time configuration default using the  
org.cougaar.core.qos.rss.ConfigFinderDataFeedComponent
This DataFeed allows you to put a file of key=value pairs on the  
config path or on a web page. When the node loads it reads this file  
into the metric service.  (RSS section of:)
   http://cougaar.cougaar.org/software/latest/doc/OnlineManual/ 
MetricsService/configuration.html
Note that this DataFeed does not poll the file/URL for changes

3) You could make your own QuO RSS DataFeed like  
ConfigFinderDataFeedComponent, GossipFeedComponent, TrivalDataFeed.  
but the base DataFeed implementations are part of the QuO RSS code  
base.  FYI: A DataFeed gets a list of Keys that need to be updated.  
If the DataFeed can get a Key's value, it sends a call back with the  
key=value pair. Whenever the value changes, the DataFeed will send  
the new value. The Metric service figures out which key=value has the  
most confidence from all the pairs supplied by all the installed  
DataFeeds.

If you want to add a new Path, that is a lot tricker and not very  
well documented.
1) You have to add a create new  QuO RSS ResourceContext, which is a  
formula that depends on other lower layer formulas. Formulas make an  
update DAG with new values coming as keys at the bottom and  
propagating calculations up to the subscribers. Example classes are  
marked with "DS", such as AgentDS.
2) You have to register your formula with the RSS, done by a yucky  
static in RSSMetricsServiceImpl

I would be interested in knowing what Keys and Paths you would like  
to added. We might add them to the standard resource metrics.

Message-ID: <fef1db450707200906m65b2844i71c76691865dbd6a@mail.gmail.com>

(Message originally posted on the CougaarSE forum, sorry for the delay)

 Hello,

I would like to know what is the best way to configure the white pages
service, knowing that I shall have a large number of hosts with a
large number of agents on each hosts (hierarchical use of different WP
servers, distributed configuration, fine tuning parameters, etc..)
Some example files would be of great help, if available.

Also, I might have missed links on this specific topic, as I found
some fine tuning parameters for the white pages service in some
configuration files but no document that fully describes the
possibilities (the specific document on the Cougaar Message Transport
Service I got dates back from 10.4) . As usual I would be glad to get
them in order to go further.

Thanks,

The primary tuning parameters are:
   -Dorg.cougaar.core.wp.server.successTTD
   -Dorg.cougaar.core.wp.server.failTTD
   -Dorg.cougaar.core.wp.server.expireTTD
   -Dorg.cougaar.core.wp.server.forwardPeriod
   -Dorg.cougaar.core.wp.resolver.transport.nagleMillis
These options control how often to renew cache and lease entries in the 
WP server.  Here's a paper I wrote on how the "TTD" settings affect the 
amount of WP traffic:
   http://cougaar.org/docman/view.php/17/176/Scalable_Naming_KIMAS_2005.ppt
   http://cougaar.org/docman/view.php/17/175/scalability_paper_kimas_05.pdf
Also see:
   http://core.cougaar.org/wiki/wiki.pl?WhitePagesMagicNumbers

You can run with multiple, fully-replicated WP servers.  I've attached 
an HTML file that describes how to setup multiple servers.  As a very 
general guideline, try (say) one WP server for every 6 hosts.

I've never used Repast or Soar, but I just took a quick look at their 
websites.  Repast appears to be a single-JVM discrete event simulator 
with a focus on Swarm-like 2-D models (e.g. ant simulations).  Soar 
appears to be a single-JVM Artificial Intelligence framework with a 
focus on learning applications.

Cougaar is designed to support distributed applications with 
peer-to-peer agent interactions.  There's no built-in Cougaar event 
simulator or global clock.  Agents are composed of "plugin" software. 
Artificial Intelligence applications can be built on top of Cougaar, 
e.g. to optimize transportation schedules:

No, Tomcat is included with Cougaar.
