Hi,

Some HP Aruba switches (entry level) work with the Net-HP-Standard-SNMP-custom model. Try it.

If I use the Net-HP-Standard-SNMP-custom model, the services ping, uptime, hardware-global work but memory and cpu do not work

I have neither this switch nor its MIB. It seems that some people are unable to obtain the CPU and RAM of this switch :

You can try manually :

snmpwalk -v2c -c YOUR_SNMP_CO  YOUR_IP .1.3.6.1.4.1.25506.2.6.1.1.1.1.6       => Net-HP-Standard-custom
snmpwalk -v2c -c YOUR_SNMP_CO  YOUR_IP .1.3.6.1.4.1.47196.4.1.1.3.22.1.0.1.1.3 => Net-Aruba-Aoscx-SNMP-custom
snmpwalk -v2c -c YOUR_SNMP_CO  YOUR_IP .1.3.6.1.4.1.11.2.14.11.5.1.9.6.1.0 => Net-Hp-Procurve-custom
snmpwalk -v2c -c YOUR_SNMP_CO YOUR_IP .1.3.6.1.2.1.25.3.3.1.2                 => HOST-RESOURCES-MIB::hrProcessorLoad (Linux, Windows, ...)

Sometimes not all informations are available with SNMP. In this case, you must deactivate the impacted services.

I downloaded the MIB and searched for the OID for CPU usage and memory usage. I found the OID .1.3.6.1.4.1.11.2.1.8.0 for CPU usage and replaced it in the Centreon template (/usr/lib/cnetreon/plugins//entreon_hp_standard_snmp.pl). Now it works. However, I cannot find the value for the memory usage and the memory size in the MIB. 

Perhaps you can help me with another problem. I have created an autodiscovery for printers. They are recognized by the autodiscovery. However, there is always an empty string under Hostname. Which SNMP command is being used here?

You should not modify the OID in the centreon_hp_standard_snmp.pl file. You can try the App-Protocol-SNMP-Numeric-Value-custom service template instead if snmpwalk returns a single value :

I don’t use host autodiscovery. You should make another post.
