Issue with Receiving SNMP Traps

[Box293]

There might be two things going on here. When your service says OK: No data received yet. this is most likely the freshness checks resetting the state of the service. More information on that is here:

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

What we need to know, when the trap is received, what log file is the trap recorded in? snmptt.log or snmpttunknown.log and what is logged?

[ssax]

Is this a new issue or related to the original issue?

Are they showing up in Admin > Unconfigured Objects?

Are they still showing up in the /var/log/snmpttunknown.log?

Are you using check freshness on your service?

https://assets.nagios.com/downloads/nag ... hness.html

TheNo data received yet. message is likely from the freshness check that resets it, please post the output of this command:

Code: Select all

grep -R 'No data received' /usr/local/nagios/etc/*

Please open your /usr/local/nagios/var/objects.cache and find the service in question, please paste the entire service configuration so that we can review it.


Thank you

Below is the output for the requested command. Hope this helps.

grep -R 'No data received' /usr/local/nagios/etc/*

/usr/local/nagios/etc/hosttemplates.cfg: check_command check_dummy!
0!"No data received yet."
/usr/local/nagios/etc/servicetemplates.cfg: check_command chec
k_dummy!0!"No data received yet."
/usr/local/nagios/etc/servicetemplates.cfg: check_command chec
k_dummy!0!"No data received yet."


Is this a new issue or related to the original issue? - This is not a new issue.

Are they showing up in Admin > Unconfigured Objects? They were earlier for the new hosts added in Nagios Sending Server.

Are they still showing up in the /var/log/snmpttunknown.log? - They no longer show up in this log.

Are you using check freshness on your service? - Not sure. How do I check this?


Please open your /usr/local/nagios/var/objects.cache and find the service in question, please paste the entire service configuration so that we can review it.

I can attach the entire cache file if needed.

Here is the more appropriate from the cache file.

Please run this command and send me the resulting /tmp/snmpfiles.zip file:

Code: Select all

zip -r /tmp/snmpfiles.zip /etc/snmp

Do you see them going into your /usr/local/nagios/var/nagios.log?

[msmulpuri]

Please find the attached. I don't see them written to the nagios.log

[ssax]

Try restarting snmptt:

Code: Select all

service snmptt restart

Send the output of these commands:

Code: Select all

ls -l /usr/sbin/snmptthandler
ls -l /usr/local/bin/snmptraphandling.py
ls -ld /usr/local/bin

Please run this tail command:

Code: Select all

tail -fn0 /var/log/snmptt/*

Let the tail command run, generate some traps, and send me the entire output.


Thank you

Below is what I have gathered per your request. It is does not make sense why the log file does not update anything which is why we are seeing the "No data received yet". I let that tail command run for quite some time but no updates.
