Nagios Support Forum

Hello Team,

Recently we have received a new request to monitor performance (ethernet traffic) of EMC Centra Storage Array via Nagios.
Can you please specify if this is possible from NagiosXI end and if yes, can you please specify the plugin details for the same.

Regards,
Aditya Anand

I'm not really familiar with this particular device but Dell has contributed plugins on the Nagios Exchange to monitor most of their equipment
https://exchange.nagios.org/directory/P ... XI/details

For interface stats I prefer to use SNMP plugins. There are many generic plugins available for that.

I find these to be useful for systems where you cannot install an agent.

For Interface stats
check_iftraffic64.pl

For other information
check_snmp_load.pl
check_snmp_environment.pl
check_disk_snmp.pl

Thanks @SteveBeauchemin!

Hello Team,

We tried to monitor via : check_iftraffic64.pl but facing the below error:

-bash-4.2$ ./check_iftraffic64.pl -H 172.25.46.187 -C public
CRITICAL: Interface index not detected ERROR: No response from remote host "172.25.46.187"

Below is the SNMP details on EMC centra Storage array:

Config# show snmp
SNMP Configuration
SNMP Status: enabled
EngineID: not configured
Heartbeat Trap Interval: 1 minute

Configured SNMP Targets

# Address Version Identity Authenticity Privacy
------------------------------------------------------

Please let us know, what needs to be done to fix the issue.

The plugin defaults to snmp version 2 and it looks like the host needs version 3. /usr/local/nagios/libexec/check_iftraffic64.pl --help has some examples using snmp version 3:

and options:

...
Example 8: check_iftraffic64.pl -H host1 --username admin --authpassword sneaky
Example 9: check_iftraffic64.pl -H host1 --username admin --authpassword sneaky123 --privpassword reallysneaky --privprotocol 3DES
...

...
-v, --Version STRING
Set SNMP version (defaults to 2). Version 2 or 3 required for 64 bit counters.

--authpassword STRING
Set v3 authorization password.
--authprotocol STRING
Set v3 authorization protocol (default: MD5).
--privpassword STRING
Set v3 privilege (encryption) string.
--privprotocol STRING
Set v3 privilege (encryption) protocol (default: DES).

Hello Team,

Sorry for the delay in response.

We tried using some examples of snmp v3 but still the same

Can you please provide me the appropriate syntax, how to use the same.

The device my not be capable of responding to SNMP requests according to some information I'm finding on it(https://www.dellemc.com/resources/en-us ... ide-wp.pdf, https://community.emc.com/docs/DOC-7739, https://pitstop.manageengine.com/portal ... mc-centera, https://www.dell.com/community/Centera/ ... -p/6713590). You'll want to check the device's documentation/with the vendor to verify. If it is only capable of SENDING snmptraps, then you'll need to follow https://assets.nagios.com/downloads/nag ... ios_XI.pdf to integrate it with XI.
