Accessing PRM’s SNMP data

You can access SNMP information through a command-line interface,

known as snmpwalk, and through a graphical user interface called

xnmbrowser. Using these utilities is described below.

Using OpenView’s snmpwalk

NOTE Secure sites may want to disable prmagt to avoid unwanted information

exchange. If prmagt is to be used, it is strongly recommended that it be

used only on a trusted internal network protected by ﬁrewalls and access

controls, due to known issues with the SNMP protocol.

To use snmpwalk to view the PRM data:

Step 1. If PRM’s SNMP agent is not already running, start it on each system

from which you want to view data:

# /opt/prm/bin/prmagt

If you need to stop the agent, use its -stop option.

You can have the agent automatically start at boot by setting the

PRM_SNMPAGT variable in the ﬁle /etc/rc.conﬁg.d/prm to 1:

PRM_SNMPAGT=1

Step 2. Run snmpwalk, giving an argument to indicate the desired information.

All information from that level and below is reported. Thus, the following

command displays all the data listed in Table C-1.

# /opt/OV/bin/snmpwalk \

hostname hp.hpSysMgt.hpUXSysMgt.hpPRM.prmReadOnly

*. The major sequence number indicates the number of times a conﬁguration has

changed since the last reset.
