Dell Servers are not reporting on Nagios Console

[Mani1]

Hi Team,

I have Nagios core 3.4.4 in our environment. From the Nagios console i could see that, few of the Dell & HP Servers Hardware status is showing "Unknown".
But, when i check Dell OMSA or HPSM, i could see the every HW status locally on respective servers.
I'm not sure, how Nagios collecting HW status from individual servers.
Whether the servers should need ILO/ DRAC or soemthing? From there Nagios collecting HW status and showing on Nagios console?
Else how it works. Please clear the query at the earliest.

Note: I used to configure SNMP string under SNMP security tab to collect to make sure server is communicating with Nagios console.
The servers i'm talking about are Windows flavours.

I'm very new to this forum. If this query was answered already, please give me the old thread details..

My guess is it's using SNMP. Can you post the full service definitions, or check commands your running to produce the results with the different manufacturers?

Hi,

Thank you for your response.

I'm using SNMP service, just the client server to communicate with Nagios console. So that it will transmit the HW status to Nagios.

When i check on Nagios console, the Dell servers are showing Unknown against server hardware. So i would like to know the fix for this.

Moreover i'm curious to know, whether server HW status are pulled thru DRAC or any other way...!

Please let me know if further details required from my end to clarify my queries.

Can you post the service definitions for a working one, and a non working one so we can see the differences?

Hi,

I have taken two servers, one is Dell and another one is HP.
The HP server picture shows the all HW status as it is.
The Dell server picture shows the HW status as "unknown"

Since i don't have any of the Dell servers status shows healthy, hence i have taken good HP server.

My query is, whether server HW status are pulled thru DRAC or any other way...!

As previously mentioned, can you post the service definitions for a working one, and a non working one so we can see the differences?

The screenshots help, but we need to take a look at the actual configuration files for these.

to get the hardware status of a dell server you need a DRAC
like your HP has an iLO card

Thanks @nozlaf!

@Mani1 - as @nozlaf mentioned, you'll need some kind of remote management port on the server.

Thank you @nozlaf!
So, without DRAC/ ILO/ IMM, nagios cannot pull the hardware status. am i right...!!!

[rkennedy]

Not exactly. Nagios can pull the information, but you'll need to do so using another resource.

Take a look at our exchange to see if you can find a different plugin that will work - https://exchange.nagios.org. You might be able to by using SNMP as well.

The final way you could do so is at an OS level, by using NRPE or NSClient++ for example.
