How to use SNMP Agent

Hi All,
Can anybody tell me how to use SNMP Agent to monitor the Access and Identity Servers

Hi Ramesh,
I cannot comment on WebLogic & SNMP - this kind of questions would
probably need to be asked on a WebLogic forum.
If you're looking for an SNMP Manager API though, you may want to have a
look at the Java Dynamic Management Kit (commercial product,
free evaluation):

Hope this helps,

How to configure SNMP agent for Oracle 10g

Hello,
I've installed oracle 10g in a Windows 2000 SP4 and I want to monitor database using SNMP.
I've already installed Windows SNMP agent but I haven't any idea how to configure Oracle in order to grant SNMP monitoring.
What should I do?
Is Oracle database ready to be monitored via SNMP by default?
Thanks in advance for your help.
Regards,
Carles

Hello,
Thanks for your message.
In fact, I already found this doc in oracle, but it just show executables I have to install and my question can I install these executables.
I've already installed Windows SNMP agent, configured and testedwith disk space checkings, but it doesn't work fine with Oracle.
I launched Oracle Universal Installer and I checked Installed Products, but I haven't found how to install SNMP agents for oracle.
How can I add Oracle Peer Master Agent and Encapsulator to my oracle installation?
Thanks again for your help.

How to use SNMP??

As a j2ee developer , how to use SNMP in our code? it is developer work? or is it administrator work???
thanks

You have to enable snmp manager process to be able to poll your device from IOS itself.
To enable snmp manager enter global config command snmp-server manager.
The SNMP manager process sends SNMP requests to agents and receives SNMP responses and notifications from agents. When the SNMP manager process is enabled, the router can query other SNMP agents and process incoming SNMP traps.
Most network security policies assume that routers will be accepting SNMP requests, sending SNMP responses, and sending SNMP notifications. With the SNMP manager functionality enabled, the router may also be sending SNMP requests, receiving SNMP responses, and receiving SNMP notifications. The security policy implementation may need to be updated prior to enabling this functionality.
SNMP requests are typically sent to UDP port 161. SNMP responses are typically sent from UDP port 161. SNMP notifications are typically sent to UDP port 162.
Examples
The following example shows how to enable the SNMP manager process:
Router(config)# snmp-server manager

How to use installed agent?

Hi all,
   EM: 12.1.0.2
   Host: RedHat 6.3 64 bits
   DB: 11.2.0.3
   I have installed successfully the Grid Control 12c on HOST01. I suppose that the installation install all the Grid control 12c binaries and an agent in the host where the repository database is. What i want to know is how to use that installed agent to monitor the repository database? I tried to manually add a target to host HOST01, but an error appears to me saying that an agent is already installed on the machine. How to use that agent to monitor my repository database?
Thanks in advance.

You can discover (add) the repository database target to start monitoring it using the following steps:
- Navigate to Setup > Add Target > Add Targets Manually
- From the Add Targets Manually page, select Add Non-Host Targets Using Guided Process
- From the Target Types drop-down list, select Oracle Database, Listener and Automatic Storage Management
- Click Add Using Guided Discovery
- From the Add Database Instance Target: Specify Host page, select the host where the repository resides, and click Continue
- Follow the process to discover the repository database

How to use scheduled agent for query in database

Hi there I'm working with database on my app and when use the query for search in the database the application freeze for a maximum of one minute I want change that why I want what runs ok and I wonder if I can use a background agent for do that manage
the queries .
But I don't know how can I call the queries from the other project if the files are in the main project.

Hi OzkarLeo,
Background task provides functionality to do work when your app not in foreground, it need some conditions to trigger.
https://msdn.microsoft.com/en-us/library/windows/apps/xaml/Hh977056(v=win.10).aspx. If you need scheduled query when app is active in foreground, then it’s no need to use background task.

How to use SNMP on WRT160Nv2?

Hello,
I would like to do some monitoring tests related to ISP DSL traffic calculations. I suspect it in false traffic calculations.
I would like to know if my WRT160Nv2 supports SNMP and how to access it (SNMP Community String etc.)?
Thank you,
Alexei Cornea

Hello,
Unfortunately I can't use the solution that you suggested.
My Router is doing the PPPoE connection. "Internet" interface is connected to an ADSL Modem that is configured in Bridge mode. Linksys Router's IP is 192.168.0.1/32. Modem's IP address is 192.168.1.254/32. There's no possibility to access this IP from PCs (DHCP 192.168.0.0/28). On Linksys WRT160N it's not possible to route 192.168.1.254/32 to the "Internet" Interface because Linksys router itself don't have an IP from 192.168.1.0/24 and it is receiving it's public/internet ip through PPPoE protocol.
I have connections by LAN on all 4 ports and a few Wireless connections. All devices are doing downloading/uploading.
Unfortunately I can use only the Linksys router as a PPPoE initiator. But, I really need to monitor all the traffic that is passing through "Internet" interface. Developing a new firmware that will support SNMP could be the best solution that Linksys Company can provide.
Please help me with a solution.
Best regards,
Alexei Cornea

How to use SNMP to access interface counters for WAN port when not in bridged mode

Hi All,
Can't fault my timecapsule, however just struggling to get one little bit of functionality working. I'm keen to get access to the WAN port interface counter information via SNMP, so I can track total bandwidth/throughput & also volume.
I have no issue getting SNMP to work & can see the 2.4 & 5.0GHz network counters, also total number of WIFI clients, wlan0, wlan1 and bridge0 interfaces. Trouble is none of these are the WAN/external ethernet port.
I see that it is likely that I'm trying to find the vlan1 port, however from what I'm reading this may only be available when the device is running in a routed mode (I'm running in bridge mode).
Anyone able to suggest anything?

Some cable modem you can turn off NAT.. and then use the TC in router mode.. or even use DMZ if the cable router allows that.
Have you ever looked at gargoyle router firmware and its ability to count and quota all clients connecting to internet service.. it is a simply fantastic firmware and can be loaded onto a router that costs $70-130 dollars.. it is 3rd party but very solid if you choose the right combo.

Use SNMP to monitor the power supply status of stacked switches

Does anybody know how to use SNMP to monitor the status of the internal power supplies of a group of stacked Cisco 3750 switches?
The switch stack has three 3750-48PS-E switches inter-connected by Cisco StackWise cable. IOS ver 12.1(19)EAlc. A single IP address is used to identify the switch stack. Every time I poll the OID chassisPs1Status (1.3.6.1.4.1.9.5.1.2.4.0 in CISCO-STACK-MIB), I only got the status for the Master switch of the switch stack. Is there any way to poll the power supply status of other switches in the switch stack?
Thanks a lot!

Sorry to refresh such an old topic - but I am stuck with exactly this: Monitoring power supplies of a stacked Cisco Catalyst 3750-E.
I'm using the exact same OID's as described, but the problem is, the information shown on the SNMP output is not correct.
This morning, a power supply of the first switch failed and switched to RPS. Here the information I got on SNMP:
snmpwalk -v 2c -c public 192.168.1.50 1.3.6.1.4.1.9.9.13.1

SNMPv2-SMI::enterprises.9.9.13.1.5.1.4.2060 = INTEGER: 2
As you see, both PS1 (for both switches) are appearing normal. It doesn't even recognize RPS:
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.1059 = STRING: "Sw1, PS1 Normal, RPS NotExist"
SNMPv2-SMI::enterprises.9.9.13.1.5.1.2.2060 = STRING: "Sw2, PS1 Normal, RPS NotExist"
The first switch's power supply died and now the cable is disconnected. LED's of the power supply are out. And still: The switch happily announces by SNMP it's power supplies are up.
Is this a known bug? If yes, has it been fixed?

SNMP Agent in Oracle 11.2g

Hello all
I wanted to use SNMP agent in Oracle 11.2g, but I read that this agent is deprecated from the Oracle 11G. I also read in a thread that Oracle will continue the support till 2018. Which one is true??
If I can't use SNMP agent what is your suggestion for its substitution?? Can I use Oracle Management Agent??
My Os : Microsoft Server 2000
Thatnk you alll

Oracle recommends to stop using SNMP going forward. Though the extended support for SNMP will be valid until Jan 2018 (Refer Metalink 1341834.1) .
The reason is not clearly given. They have mentioned that from oracle database 12 cloud control onwards , SNMP is completely removed. Probably that is the reason.
It might be okay to use it, until your environment gets upgraded to oracle 12c.

I have set up LINUX and virtual agent configs a couple of times, and it has worked pretty ok.
What I found was that you might have to download a newer version of PLINK.exe and put that onto your OLT system.
(with the packaged version, I also had some communication issues)
Try to download the lates plink.exe and see if that works…
(you may want to restart you system after replacing plink.exe)

How to do a SET using SNMP ?

Hi,
I already ask in the forum Advanced Language Topics
http://forum.java.sun.com/thread.jsp?forum=4&thread=320674
but I din't receive any answer so I try here maybe some one could help me on this ... ;-)
I find a nice piece of code on Internet to do SNMP request �
http://membres.lycos.fr/ysoun/index.html
http://membres.lycos.fr/ysoun/sck.zip
It works find to do some GET operations like doing a GET sysDescr (oid 1.3.6.1.2.1.1.1.0).
But I would like to do a SET operation but I could'nt succeed.
First I do a get on an oid 1.3.6.1.2.1.1.4.0 (sysContact) and I get the value "hello" which is find and I would like to set this value to "good bye".
Well I have to say that I don�t know very well the SNMP protocol and I couldn�t figure out where to put the value in order to set "Good bye". Off course I have the right community to do that but I just can't figure out how can I do that ...
Any comment ... help ... ideas ... are more than welcome !!!! Or maybe some better SNMP package to do that???
thanks,
Emmanuel

I read the documentation it does not help me much, (it's generated by javadoc and there is not enought comment to understand the whole thing ... in fact it just miss a sample of SET request and it would be perfect ...
thanks,

PS: I'm going to try the author again
PS: Still ... any help or pakage to do SET request using SNMP are more than welcome ...
