I cannot. I don't use check_udp and don't know the SNMP protocol at such a basic level to know what to send. I imagine that it's not a simple string for this protocol. Your best bet, if you cannot use check_snmp instead, would be to capture a successful query/response pair with ethereal and see if it can be made to work based on the send/ expect you find in the capture. -- Marc - Check out the new SourceForge.net Marketplace.

Re: [Nagios-users] About check_udp plugin
Hello, Thank you for the reply. So, could you please give me an advice of how to use the check_udp? I have trouble with specifying the "send" and "expect" parameters... For example, I would like to know the parameters to specify to check the 161 udp port, which is the snmp service in our network device.

Re: [Nagios-users] About check_udp plugin
Hello, I just want to confirm that whether the UDP 161 port is available not . We don't need to know if the service is up or not. Like you mentioned , I think the best way is to access to the agent. However, is there any plugin that just confirms that the UDP 161 port is available or not ? If no, I will use the check_snmp and access to the agent.

It depends on what you consider useful. It's entirely possible for a port to establish a connection but not actually be working at higher levels (i.e. answering queries). In your case, you've only determined that there's something listening on the port, not that it's snmpd, actually working or returning data you expect. IMHO, if there's a higher level test that's possible like check_snmp in this case, that will be a more accurate and useful test. -- Marc - Check out the new SourceForge.net Marketplace.

Re: [Nagios-users] About check_udp plugin
Hello, I used the check_udp service , like check_tcp, to check whether the 161 is useful or not. Is this not the write way to use it ?

Re: [Nagios-users] About check_udp plugin
Hi, The SNMP service only answers to well formated SNMP requests, with the correct community set, so you can't check SNMP service with UDP check because it doesn't send an SNMP request. You must use check_snmp.
