Nagios Support Forum

Hi Team,

We have a requirement to enable the PDU monitoring on Nagios XI (monitors like voltage, current, load). Please help me understand how do I enable it.

NagiosXI version : 5.8.5
PDU make n model: HPE G2 Mtrd 3P 22kVA/60309 Vt INTL PDU

We haven't enabled this till date.

Hello @sneha.irali

Thanks for reaching out, understand that you would like to monitor PDU.

Depending on the device you may be able to configure to accept SNMP monitoring, please check with the manufacture's make and model to verify.

Otherwise, you can utilize a plugin from the Nagios Exchange.

Thanks,

SNMP v3 is already enabled on the PDU.

Now my query is:

- how do i discover the device since the device is not yet been discovered
- how do i utilize the exchange plug in to enable the monitoring for voltage,current,load.

Hello @sneha.irali

Thanks for following up, do you know the mac address of the PDU.

One of two methods;

• Head over to the Nagios XI web console > Configure > Auto-Discovery > Run Scan > View results
• Run nmap command to find:
[list]

• Code: Select all

  nmap -sP xxx.xxx.xxx.0/24 | grep -B 2 "xx:xx:xx:xx:xx:xx"

• nmap -sP <youridaddressrange> | grep -B 2 <"yourmacaddress>

[/list]

Once you have determined the IP Address of the PDU, we would suggest adding it manually from the Nagios XI web console under Configure.

Thanks,
Perry

I have the IP addr and Mac info.

Which wizard do i use to manually add the device on NagiosXI GUI.

basically i am looking out for a step by step process.

Hello @sneha.irali

Thanks for following up, sounds like you have configured your PDU to accept snmp, and the next steps include:

• Walk through snmpwalk to scan your PDU:
[list]
• snmp Walk Wizard

[/list]

Once you have verified the snmpwalk scan, and determined the mibs/oid's from the scan, please see snmp walk Wizard documentation to configure snmp for your PDU using SNMP-Monitoring-Wizard. Configure the mib's/oid's using the 'SNMP Monitoring Wizard' during menu-driven setup for configuration.

Please let us know if you have any further questions.
Perry

So Basically, after I do the snmp scanning I would need the OID's that needs to be enabled.

Hello @sneha.irali

Yes, you are correct that you will need the Object Identifier from the mib. You can find a database of mib's here:
