Nagios Support Forum

Hi everyone,

Has anyone successfully uploaded the latest Dell iDRAC MIB to their Nagios server and integrated it successfully? I attempted to use the check_idrac plugin found at (https://exchange.nagios.org/directory/P ... AC/details) but ran into some erratic output on servers with newer iDRAC firmware. That issue led me to attempt to use SNMP traps for Dell since I had successfully accomplished the task previously for APC Uninterruptible Power Supplies. I uploaded the attached iDRAC file from the NagiosXI web page. My problem is that although Nagios received the traps successfully in the /var/log/snmptt/smnptt.log it does not change the trap status for the iDRAC. The check sits at pending despite simulating a loss of a power supply unit for a server.

If I grep the contents of APC under /etc/snmp/snmptt.conf I get a substatial amount of output such as:

FORMAT APC CODE: PowerChute has detected that a newer version is available.: PowerChute has detected that a newer version is available.
EXEC /usr/local/bin/snmptraphandling.py "$r" "SNMP Traps" "$s" "$@" "$-*" "APC CODE: PowerChute has detected that a newer version is available.: PowerChute has detected that a newer version is available."
FORMAT APC UPS: On temporary bypass: The UPS is on temporary bypass.
EXEC /usr/local/bin/snmptraphandling.py "$r" "SNMP Traps" "$s" "$@" "$-*" "APC UPS: On temporary bypass: The UPS is on temporary bypass."


If I grep for Dell I only see the following line.

MIB: IDRAC-MIB-SMIv2 (file:/usr/share/snmp/mibs/DELL-iDRAC.mib) converted on Wed Apr 11 23:24:36 2018 using snmpttconvertmib v1.3

Hello, @IT-OPS-SYS. Did you download the check_idrac from the nagios exchange page or from the authors github page?
https://github.com/dangmocrang/check_idrac
On his github page it looks like he did some commits recently, and you can get the latest version which is [2.2rc4] versus the one we have on the exchange is 2.1. So if you haven't tried the latest version yet please do.

I looked into your snmptt.conf file and I haven't found the entry for the oid number .1.3.6.1.4.1.674.10892.5.3.2.1.0.2185. So I suspect these traps are getting caught by some generic trap definition.
You need to either: get the MIB that will contain the entry for the oid #.1.3.6.1.4.1.674.10892.5.3.2.1.0.2185, or you can copy an existing OID in snmptt.conf and change it to .1.3.6.1.4.1.674.10892.5.3.2.1.0.2185.
Also, you trap needs to look like this. Take a look at the arguments used in this example trap and try to modify your trap to look similar.

Hi npolovenko,

I tried an previous and the existing version of the plugin with mixed success. I removed the Dell MIB I found and attempted to upload it again but am receiving the following error.

Failed to converted mib path to snmptt.ini. (rc: 4)

I see this in the apache logs:

touch: cannot touch '/etc/snmp/snmptt.conf': Permission denied
/bin/sed: couldn't open temporary file /etc/snmp/sedhzu9oD: Permission denied
touch: cannot touch '/etc/snmp/snmptt.conf': Permission denied
/bin/sed: couldn't open temporary file /etc/snmp/sedpQQVda: Permission denied


The snmp folder permissions are currently

drwxr-xr-x. 2 root root 100 Apr 13 14:33 snmp

@ IT-OPS-SYS, You have a permission problem. Run this command to change the owner of the /etc/snmp/ folder: Do you have anything in unconfigured objects in XI? After the oid definition is added you need to add the match statements. Take a look at the "Create Custom Events In SNMPTT" section of this tutorial.

Please run the following three commands to archive all the snmp files and configs that we need to take a look at: And then upload the following archives:

Hi npolovenko,

Your suggestion worked and resolved the permissions issue. I have not had time to look into this issue further but you can lock this thread if you like. Thanks for everyone's assistance.

[user]IT-OPS-SYS »[/user], Thanks for an update! I will be closing this thread.
