Dell network devices (S-Series/OS10) monitoring fail

​@Secast 👋

for #1

UNKNOWN: SNMP GET Request : Can't get a single value​

SNMP Plugins request one or several OIDs from the target devices' MIBS. When it doesn't obtain a value for one of these OIDs, it returns an UNKNOWN state to warn the user.

Frequently, the device doesn't ship the MIB or one of the OIDs the Plugin utilizes. In other words, the Plugin used is not suitable for this device.

is this the one you are using?

for #2 what is the error/perl missing?

Hi,

#1 yes that’s the error i’m getting.I have read this article which conclude in :

In other words, the Plugin used is not suitable for this device.

That’s why I’m asking if somebody is using the Dell S-Serie plugin to monitor S-Series Dell networking devices as it seems that it is not suitable for my S4148/S4128 devices 😅

#2 the error is

(Execute command failed)

So I went to check for the command used by the service (load for exemple) wich is :

/usr/lib/centreon/plugins//centreon_dell_os10_snmp.pl
--plugin=network::dell::os10::snmp::plugin……

I finally managed to get the perl script missing.

When you install the plugin for OS10 through the connector, you also have to install the package from cli :  

dnf install centreon-plugin-Network-Dell-Os10-Snmp

Now the perl script can be launched as expected and I’m getting metrics.

However, there is a “bug” in the swap service command.When you look at the command detail you can see all args used :

/usr/lib/centreon/plugins//centreon_dell_os10_snmp.pl
  --plugin=network::dell::os10::snmp::plugin
  --mode=swap
  --hostname=192.168.XX.XX
  --snmp-version='1'
  --snmp-community='XXX' 
  --warning-usage=':10'
  --critical-usage=':30'
  --warning-usage-prct='80'
  --critical-usage-prct='90'--warning-usage-free='20'
  --critical-usage-free='10'
  --verbose

It seems to be missing a carriage return between two arguments making the command believe all the line is the arg value.

As a consequence, the service is showing the following error :

UNKNOWN: Wrong critical-usage-prct threshold '90--warning-usage-free=20'.

Does anybody know how I can “fix” this behaviour ?

Regards

Great to hear you were able to install them!

Which version of the pack are you using? the format appears to be ok on 

rpm -qai centreon-pack-network-dell-os10-snmp
...
Version     : 25.01.2
Release     : 1.el9
...

I don’t have any centreon-pack-network-dell-os10-snmp but i do have a centreon-plugin-Network-Dell-Os10-Snmp :
