Hi Experts,

I want to setup an SNMP Server for some tests.
This server should accept all the traps which are coming from my devices.
And each message should be sent via email to me.
Can you help me to do this ?
Or can I use some predefined tools ?

also important for me is a SNMP TRAP SERVER.
Because I want to be informed via email about critical states.

I recommend Paessler PRTG.  It's easy to set up as it does most things automatically.  The main thing is coordination of the Community String / like a passphrase.  They all need to match.  The default is "Public" and I normally use something else.  Either way....
Not sure what your issue is. Install the SNMP feature.
Then configure the service snmptrap and configure your devices to trap to the server after making sure to adjust the advanced firewall settings to allow UDP 162 destined packets through.

Presumably receiving the traps is just the begining.
One option to avoid messing with yoiur system is to create a VM running linux and you can tinker with that and opensource apps to get to what you want after seeing what is available.

Thanks for the answers.
I know how to enable SNMP feature.
But I need a trap server to collect all messages and send me alerts via email.
I think this is not possible just with the SNMP Feature, right ?

Any suggestions ?
Dan McFaddenSystems EngineerCommented:
I'd suggest one of the following:

- PRTG :
- OpenNMS :
- TheDude :

yes, the snmp feature just sets up the receiver. you need an additional tool to scan through event viewer and based on a preset criteria once the event is seen, your process will have to do what you wantr.
the paessler prtg recommended might be whgat you need.

usually, you might want to look at the monitoring tools, nagios,zabbix, opennms, etc.

 you can both proactively monitor your systems/network, with some having snmptra receiver thgat can include device/system generatying events/records.
Eprs_AdminSystem ArchitectAuthor Commented:
Yes I also have heard from THE DUDE.
Including the other monitoring free solutions, all of them are trap receiver ?

Ineed a tool to receive traps, show the alertss and send them further to an email recipient.
best way is for free or open source.

But PRTG is very expensive and the 100 sensors are not enough.
Dan McFaddenSystems EngineerCommented:
Then I would look into OpenMNS or Nagois.  (link:

And yes, these packages can be setup to receive SNMP traps and log them and do notification.  They can also consume various system logs and report on them as well.

I have installed now OPENNMS.
But can you help me to change all my snmp traffic to another community ?
What I have to do for this ?
Eprs_AdminSystem ArchitectAuthor Commented:
can you also help me with an snmp test tool to send or receive ?
Dan McFaddenSystems EngineerCommented:
On the server:

1. open computer manager
2. go to services
3. find the service named:  "SNMP Service"
4. right-click and select properties
5. go to the "Trap" tab
6. type in a new community name and click "Add to list"
7. with the new community name select, under "Trap destinations" click Add
8. enter the SNMP Trap destination IP address (the IP of your OpenMNS server) & click Add
9. OK your way out

You will also want to set the security on the community.

How to article:

Basically set the community name to the same thing as defined on the traps tab.  Setting the community rights should be documented in the OpenMNS admin/user guide.
