We have installed SNMPv3 on an AIX server. I was able to use the SNMP Wizard to code a host and a CPU service. Here are the configs with proprietary info redacted...

Hosts configuration

define host {
host_name REMOTESERVER
use xiwizard_genericnetdevice_host
address REMOTESVRIP
max_check_attempts 5
check_interval 5
retry_interval 1
check_period xi_timeperiod_24x7
contacts NAGIOSADMIN
notification_interval 60
notification_period xi_timeperiod_24x7
icon_image snmp.png
statusmap_image snmp.png
_xiwizard snmp
register 1
}



Services configuration

define service {
host_name REMOTESERVER
service_description CPU Utilization
use xiwizard_snmp_service
check_command check_xi_service_snmp! -o 1.3.6.1.4.1.2.6.191.1.2.1.0 -P 3 --seclevel=authPriv --secname=USER --authproto=md5 --authpasswd='AUTHPASSWORD' --privpasswd='PRIVPASSWORD' --privproto=des -l "CPU"!!!!!!!
max_check_attempts 5
check_interval 5
retry_interval 1
check_period xi_timeperiod_24x7
notification_interval 60
notification_period xi_timeperiod_24x7
contacts NAGIOSADMIN
_xiwizard snmp
register 1
}


However, we now want to add numerous other services: disk utilization for about 10 different file systems, page usage, etc.

I can get the OID's but would prefer using a MIB. Not sure how to do this.
But, I can't find any decent step-by-step instructions on how to code a new service using SNMP.
Can you point me to a youtube or PDF that has such information for customized monitoring using SNMP?

@mkeey, First, please obtain the MIB files from the manufacturer of the device you're looking to monitor.
Next, in XI web interface go to the Admin menu, click on Manage Mibs in the left column and upload the MIB files. No need to check the "Process Traps" box.
Once the MIB files are uploaded run the SNMP Walk Wizard against your device. It should automatically translate OIDs to readable SNMP counters according to the MIB files you uploaded.

I did download the MIB file and installed it via the XI GUI...

I tried using the Walk Wizard but it didn't recognize the IBM-AIX-MIB.mib - See SNMP Walk #1 screen print.
The results are shown in SNMP Walk #2 screen print also attached.

Second comment. The PDF you directed me towards only discusses SNMPv2 not SNMPv3.

@mkeey, Please delete the IBM-AIX-MIB.mib from the OID field in the wizard, run it again and show me a screenshot of what it finds.

Did as you requested. See attached screen prints. Clicked on next and got odd results. Clicked next and got an error saying I didn't select any OID's.

@mkeey, Please upload the MIB file in this thread.
Also, please run the SNMPwalk command from the command line and show me the output(or send it to me in a private message):

We have gotten the SNMP to work. The snmpwalk did help. Just have some questions about thresholds and that's being worked on in a separate case. Please close this one.
