Hi Sanjeev
My Wls agent is working fine as Master agent with Sun's Snmpdx as subagentto it.
There is no problem with that.
But can I make WLS agent, subagent to Sun's Snmp Agent.For that I need WlsSubAgent resource
files to be included in the configuration directory of Sun's Snmp Agent.The last time i checked, Sun's master agent is more "loosely coupled" with
other agents it needs to co-ordinate with. I haven't tried it, however i
beleive it should work. Because the master agent doesn't rely on built-in
protocol for interaction with other agents. (much like -otherAgents option
in the wls agent).
You just need to specify in SUN's syntax (resource files...) where the wls
agent is running, what is its community, which MIBs it supports , what
should be the timeout and such ...
Good Luck!
If you run into any problem let me know.

Re: Wls agent as subagent to Sun's Snmp Master Agent

I have successfully configured the WL SNMP agent as subagent to
Sun's (Solaris 7 in my case) master SNMP agent.
Sun's Solstice Enterprise Agent documentation under docs.sun.com
is a bit confusing but serves as a reference if not a step-by-step guide.
Here are the general steps that I took:
1) Modify the shipped startSNMPAgent.sh for your system password
and community (I wouldn't use "public"!).
Add some if-then-fi code to check for the $1 command line parameter,
so Sun's master agent can pass in the dynamically allocated port number
that the agent will listen to. I also changed the ownership of this
script so only root can see it, as it contains the WL admin password.
2) Go to the /etc/snmp/conf directory (default Solaris 7 install).
Create the files weblogic.rsrc and weblogic.reg using the mibiisa.*
files as templates.
3) In the weblogic.reg file, add the lines
"macros = { bea = enterprise.140 }" before the "agents" line.
This defines the weblogic agent's starting OID point.
Then, change the subtree line to "bea".
4) In the .rsrc file, change the command used to spawn the
agent to "/weblogic/startSNMPAgent.sh $PORT".
Be aware that this spawn command is visible through Sun's master
agent MIB, so don't put anything sensitive in there (like a
community name or password).
5) Finally, there is a timing condition that you should be aware of.
WebLogic's SNMP agent will only bind to an active WL server.
Sun's master agent will only bind to an active subagent.
Therefore, you should ensure that
WebLogic server is started first (and the server comes completely
up), then Sun's master agent is started. I setup my /etc/rc3.d
startup files to run weblogic before snmpdx. I had to insert a
sleep command to make sure that WL was completely up before
snmpdx was run. This is because my startup script runs java in
the background, so if you don't sleep then WL won't be up before
snmpdx spawns the subagent and tries to bind to it.
Finally, Sun's mib files can be found under /var/snmp/mib.
Easier to find than NT's mib files!
Hope that helps -

Hello:
I created exactly as you specified. I.e weblogic.reg, weblogic.rsrc, weblogic.acl. But the issue I have is My weblogic snmp agent is listening on port 8061. Snmp demon on 161. So when I request the Snmp demon with OID of weblogic object. I am not getting the result also call is not reaching weblogic agent. Instead I am getting no such name or OID. So I am wondering why snmp demon is not forwarding the request to snmp demon.
Also Could you please explain the execution sequence of snmp demon and where you think I need to look at. Also please explain the constructs used in reg/acl/rsrc files.
Note:
I am using wls 6.1 sp2. So just my starting admin server. The enabled snmp gets started. Also I configured snmp demon so that when ever it gets started the weblogic server also starts. Also there is no issue in receiving traps.
Thanks in Advance.

Migrating from UCD snmp to SUN snmp

Hi, Can anyone tell me if there is an easy way to migrate from UCD snmp we currently use to SUN snmp. Basically we currently have a config file snmpd.conf and use it for monitoring. We'd like to migrate as seamlessly to SUN snmp as possible. Any help is appreciated. Thank you.

Hi Jeff,
This is definitely OS/DB migration. since the binary codes are different between Sparc and AMD CPUs. You will need certified migration specialist to perform it. That is required from SAP for support reason.
I've done few migrations. It is complex process and it's duration depends of your dictionary and size of cluster tables.
Good luck,

SNMP subagent with SMUX SNMP master agent

I'm looking for the smux agent configuration for ucp-snmp to be able to use it as the master agent on a Linux/Solaris server. The subagent would be the LDAP instance snmp sub-agent. According to the documentation, if I have a master agent that I can't get rid of and is smux compliant, I can use it instead of the Netscape SNMP Master agent.
Even by configuring the ucp-snmp master agent as per the Netscape Directory Server documentation, the subagent is not starting. I always get the following error: "Unexpected error" in the console 4.2 window.
I'm using a Netscape Directory Server 4.16
Can anybody help me on what should be the smux configuration and then how to start the LDAP instance subagent?

Hi,
Iplanet does not support for it's products being installed on linux or snmp for linux.

SNMP traps from Solaris 10

Hi,
I'm trying very hard to set up a Sun Fire V245 to send SNMP traps when certain hardware or software related events occur. I've been looking at sma_snmp (net-snmp) and the Fault Management Daemon (SUNWfmd) but they seem to be very limited in their capabilities. I have manged to get some traps sent for filesystem fill-ups and high load averages but that is about it.
Most of all I would like the system to send traps when there is a HW failure such as a faulty FRU or if there are disk failures.
If anyone can point me to some documentation about this, I would be most grateful.
/Mikael

Mikael,
I struggled through the same thing with a Netra 240 recently. The Sun docs are garbage when it comes to this. I opened a ticket with Sun and after 3 days and 6 hours on the phone I finally got hold of someone who knew how to spell SNMP. Yes, it was that bad!
Here's the scoop. In Solaris 10 you run Net-SNMP, a.k.a. SMA, snmpd. The old snmpdx is obsoleted and you shouldn't configure it at all.
Now to get the hardware related traps for the Sunfire and Netra series servers... (what you are really looking for).
You have to load and configure an additional SNMP daemon for the hardware specific traps.
(The first doc is rather old, the last one 819-7978-12 is pretty new and is somewhat more relevant.)
Sun� SNMP Management Agent for Sun Fire� and Netra� Systems: Sun Doc number 817-2559-13
Sun� SNMP Management Agent Addendum for the Netra� 240 Server: Sun Doc Number 817-6238-10
Sun� SNMP Management Agent Administration Guide for Sun Blade� /Sun Fire�/Sun SPARC� Enterprise/Netra� Servers: Sun Doc Number 819-7978-12
And finally the SMA/net-snmp/snmpd guide for the standard Solaris related traps:
Solaris System Management Agent Administration Guide: Sun Doc Number 817�3000�11
There are problems with all of the above documents. None of the Netra/Sunfire docs specifically talk about Solaris 10 so read them with caution. They also talk about configuring and running snmpdx and never reference SMA/net-snmp. This is odd because the instructions I got from Sun (finally) were not to run snmpdx, only to run sma/snmpd and additionally run the sunfire/netra snmpd agent.
The SMA document (817-3000-11) has an undocumented bug, which Sun knows about and is working on but will not reveal to the public. In the section titled "Migration From the Sun Fire Management Agent" it references using a script called masfcnv to convert the sunfire/netra specific snmp config and daemon to work with and through SMA. Since they all use the same ports (161/162) there is some conflict and the masfcnv is script is meant to resolve this by making sma/snmpd a proxy agent to requests toward the sunfire/netra specific hardware daemon.
The problem is the masfcnv script doesn't work properly. In fact, if you run the script you will destroy your other snmp configurations and may have to uninstall and reinstall the packages to clean everything up. This script hasn't ever worked and Sun is working on a fix but they neglect to mention this in the document which is IMO gross negligence and is a reflection of Sun's overall state of affairs (but that's another ranting thread).
So what you must do is configure SMA/net-snmp (or whatever you want to call it), and also configure the sunfire/netra specific snmp (after downloading and installing that package).
Since traps are sent to the remote trapsink using destination port 162, both net-snmp and the netra specific snmp daemons can co-exist here (port 162 is not an open listening port on the machine).
Port 161 is used for receiving SNMP Get requests and can only be bound to one daemon at a time. So either it is used by net-snmp or the netra snmp daemon, but not both. Since my boxes have not been fully integrated still I can't figure out which daemon 161 is bound to. At any rate, in my application the customer is only interested in receiving traps so the outcome here isn't that important.
I realize this isn't complete but I'm no expert here and haven't worked through all the test scenarios on a fully configured system. Hopefully though this will help clear some of the confusion propogated through Sun's stupid documents. Good luck!

Monitor ETL process using SNMP

Hi,
I have an ETL process that runs continuously and add lines to a table under Oracle 11g on Linux. I would like to monitor the proper operation of the ETL using an external SNMP manager (eg Zabbix). To do this the algorithm would be like this:
- List and count lines that have been to the table durig the last n minutes;
- Update an SNMP counter
- Repeat every n minutes.
I was thinking about creating a small Perl subagent for net-snmp that would execute an SQL query using JDBC, but is there a better way to do this? For instance by using an Ora

I assume you're talking about scripting this? Probably the easiest thing to do would be to use Curl. I've attached an example. You'll need to change a couple values for it to work.
The output is different than what you'd get if you did a "df" using the service account. You'll have to decide which output you require.

SNMP on Solaris 10

Hi Experts,
Ive got a T1000 server installed with Sun� SNMP Management Agent for Sun Fire� and Netra� and SMA. The client has requested to generate some not harmful test traps from the server. I tried this by unplugging an ethernet interface or by unplugging one of the redundant power supplies hoping to see traps containing detailed information about these events. But all i got on my node manager (HP Open View) was traps like these:
Indicates that attribute identified by sunPlatNotificationChangedOID
has changed from the value in sunPlatNotificationOldInteger to the value in sunPlatNotificationNewInteger.
This is as defined in X.721, sec. 13.1.3\%X07D8060B0A3213002D0500\{ 1 3 6 1 2 1 47 1 1 1 1 2 29 }\""\{ 1 3 6 1 4 1 42 2 70 101 1 1 12 1 2 29 }\2\1
I also tried monitoring the traps by using the command snmptrapd -P. Also got the traps but still with no detailed information about the events.
As you can see there is no detailed info about the generated events.
Am i missing something or its just that simple as the product works like this?
Maybe there are some others not harmful traps for the server with detailed information that i can test?
Thanks in advance.

I could use some help with this as well ... so far I have been unable to find a clear and concise document that can walk me through configurin gSNMP. Clean Solaris 10 installation, snmpdx is running - now how do I configure it? Better yet, how do I disable snmpdx and run net-snmp?
Please, someone help or at least paste a link to an article somewhere...

Help with JMX, SNMP in my app.

My app has bunch of EJBs(in Jars) and one WAR file. Everything is packaged inside EAR file. My app is using JDBC and IMAP connections. Currently SNMP implementation is very simple - we jsut sending fixed trap with variable VarBind information.(no set/get functionality). Please elt me know if somebody implemented MBeans for their application. We are planning to have a full set/get functionality with MIB defined through SNMP Agent on WLS. IS it possible? I would like to hear some ideas on how to implement it.
Thank you foir your help in advance.

I would like to be able to do gets and sets on my EJBs and WebApps from
a remote SNMP
client manager. I know sets cannot be done to WL MBeans using the
WebLogic SNMP Service. I see two ways
to go, run an AdventNet or Sun SNMP adapter in each WL Server which will
forward
SNMP requests to the MBeanServer or run my own SNMP agent which is
proxied from
the WL SNMP agent. The WL SNMP agent does not allow sets, will it
forward set commands
to other SNMP agents it is proxying for?

Rick/Stanislav, could you please elaborate ?
Do you want to add to the BEA MIB - that is not possible
if you want to write custom MBeans to monitor things, you certiainly can by registering your notificationListener on the mbean...
I dont think, it would be possible to monitor a custom MBean through SNMP.
my 2 cents,

Net-snmp

I have solaris 9 x86 and I downloaded net-snmp from sunfreeware and i install it in /usr/local.
I configured /etc/snmp/conf/snmpd.conf :
sysdescr Sun SNMP Agent :
syscontact xxxxxx
syslocation xxxxxx
system read-comunity public
read-comunity public
manager localhost
I did :
/etc/init.d/init.dmi stop
/etc/init.d/snmpdx stop
/usr/lib/snmp/mibiisa stop
etc/init.d/init.dmi start
/etc/init.d/snmpdx start
/usr/lib/snmp/mibiisa start
I have /usr/local/bin in my path and when i do snmpwalk localhost or snmpwalk 192.x.x.x in my local network i always get snmpwalk:Timeout
Can someone help me to explain me how to setup net-snmp on solaris x86 step by step
Thanks

I don't have access to a solaris 9 x86 system but perhaps the problem is your misspelling of community in the system read-comunity<sic> and read-comunity<sic> fields in the snmpd.conf file?

How to add osmonitor to servers

Hi all,
 
I have a bunch of galaxy servers installed with our jumpstart server. I would know manage them with N1SM. I can discover those server without any problem but can't enable the osmonitoring. Trying adding this feature always end up with :
 
Result 1: 
Server: xxx.xxx.xxx.xxx 
Status: -3 
Message: Enabling Base Management or OS Monitoring support failed. Check the Standard Output field for possible reasons for this failure. 
Standard Output: 
SunMC driver: getV3 failed: noError,-1 
 
Result 2: 
Server: xxx.xxx.xxx.xxx 
Status: 0 
Message: Failed to enable OS Monitoring support. 
 
 
How can add enable it ?
 
Best regards,

Sorry for the delay - been busy....
Ok, as far as I have been able to find, and in talking with SUN engineering, when you attempt to enable the osmonitor feature, what it actually does is install a Solaris package ( SUNWn1smsparcag-1-2 ) on the managed server.
In this package, a "lite" copy if the SunMC agent get's installed, which is typically what would be installed to enable container manager, but it's not the fully functional copy of SunMC ( SUN Management Center - V3.6.1 ). Either copy uses snmp for it's reporting capabilities, but the full copy is more easily configured to use a defferent port then 161.
My understanding is the lite copy installs as a sub-agent to the SUN native snmpd, so with that, I was a bit misleading in my previous reply.
If you have "net-snmp" installed, you might be able to configure it as a sub-agent to SUN's native snmp and get the osmonitor feature working as well, I haven't tried that combination. Aslo, you can't install the full copy of SunMC on the managed server, then enable the osmonitor feature as it creates it's own port conflict. And if you attempt to install SunMC after enabling the osmonitor feature, you'll get similiar results.
As for modifying the snmpd.conf, in one "raw" attempt I did not have to, ie, clean install of N1 System Manager on my management server as well as a clean install on the managed server without SunMC. Then a discovery, enabled base management, the osmonitor feature and it worked. Also, this was without modifying the snmp model on the managed server, ie, I did not install net-snmp and did not modify any of the SUN snmp configuration files.
Also, keep in mind something, the osmonitor feature when enabled does not give a tremendeous amount of added info so it begs the question "why bother"?
Most shops monitor disk space, cpu and memory use via something similiar to What's up Gold, etc.
As I find more info on the total functional configuration requirements, I'll reply further

Solstice agent - other agents

Hi all,
As being new to SNMP and Solaris, I think I have a fairly easy question for you guys.
We're currently running Solaris 9 on V440 and V420 boxes.
I'll have to perform some monitoring on these and SNMP drawed my attention.
But on the system curently only the SUNWsasm package is installed and running (Solstice enterprise agent) A simple snmpwalk could not be performed. Is this package enough or....
In the Sun SNMP manager agent Admin guide for Sun Fire v420 and 440 I found nevertheless other packages which should be installed:
SUNWmasf, SUNWmasfr + the commom config reader for the V440 and 420).
Thanks for the help; which is very much appreciated.
best regards,
Geoff

Hi Rick, thanks for your interest
What's different about this "empty agent"? It doesn't have a pernr?
No, it does not have a pernr nor anything else. Whenever you access to the responsible agents list popup from the workflow log, there are as many entries as pernrs, and additionally, this empty line on top, but just sometimes
How is the role returning this list of pernrs? Could it be that
there's a programming error there? Could you change it to check
for this empty agent and remove it before it gets passed to the workflow?
I have rechecked the role outside the workflow and it never returns an empty row. To me, it looks like it happens something once the role has been executed, so a "empty object" is added to the list of possible agents.
However, If the problem persists and we do not find the root, I will modify the role to delete any possible empty rows, just in case. Thanks for the tip

Specifying TRAP-RECIPIENTS

Hi,
I am trying to run the snmpdemod programm which came with the SEA package.
1. I am able to use snmp_trapsend and send traps
2. My snmpdemod process is up and running without any errors
3. GET and SET methods are working fine
...but, I don't know where to specify TRAP-RECIPIENTS, so that the traps are directed to the specified recipient.
This would be my last hurdle to succesfully run snmpdemod agent.
thanks in advance
regards
Santhosh K.

snmpd.conf is used by the Sun SNMP agent, mibiisa. The way I resolved the issue was by copying the trap parameters for my enterprise from snmpdemo.acl to snmpdx.acl.
