Hi,

Thanks for the suggestion. I might look into this at a later date.
Meanwhile, I have solved the issue using a java command available for
obtaining Weblogic data.

The command goes like this:

java weblogic.Admin -url t3://localhost:7001 -username weblogic
-password 
weblogic GET -pretty -type JVMRuntime

You can substitute the "type" flag in the above to obtain whatever you
need (in this case, its JVMRuntime). There a list of types available at:
http://edocs.bea.com/wls/docs81/javadocs/index.html
(weblogic.management.runtime)


Regards,
sg

Hi Sandeep,

I am looking for this kinf of plugin too but could not find any hints on

the web.

I think the easiest way could be some snmp stuff to your bea server.

The vendor information about Bea SNMP is quiet nice like this one (maybe

old - I am not a "Bea", I'm a "Nagios" ^^ )

http://e-docs.bea.com/wls/docs70/snmp/snmpintro.html

After managing the snmp agent on your Bea server it should be possible
to:

snmpwalk -c COMUNITA at BEASERVERNAME -v1 IP_ADDRESS

On the link above you can read nearly all possible informations directly

out of your weblogic system like

jvmRuntimeHeapSizeCurrent ====> 1.3.6.1.4.1.140.625.340.1.30

I am testing this with

JDBC Connection Pool Runtime Table

specially with

jdbcConnectionPoolRuntimeActiveConnectionsCurrentCount 
====>1.3.6.1.4.1.140.625.190.1.25

if I am now doing a:

snmpwalk -c COMUNITA at BEASERVERNAME -v1 IP_ADDRESS 
1.3.6.1.4.1.140.625.190.1.25

i'm getting some snmpwalk output like:

1.3.6.1.4.1.140.625.190.1.25.24.657.101.102.34.35.773.14.2.3.44.21.35.81
.357.3.what.the.hell 
= INTEGER: 6

just figured out that: 
"24.657.101.102.34.35.773.14.2.3.44.21.35.81.357.3.what.the.hell" has 
something to do with this special connection pool, but I can't figure 
out how I can get this special one Integer for 
ActiveConnectionsCurrentCount for this special ConnectionPool 
"NAME_OF_CONN_POOL".

Perhaps here is somebody on the list who can explain or give some hints 
on these type of "snmp mib redirects"? (Couldn't explain better).

I will work on it, but if you (or some other) have any hints on it, 
please let me know.

Thanks in advance
Hendrik
