Summary Advanced hardware monitoring has been a key requirement for a longer period of time. With the

release of Webwasher 6.8.3 build 4533, aka 6.8.3 rev c, McAfee introduced more hardware monitoring

capabilities based on the SNMP protocol.

This document will describe the required steps to install and enabled those features and will give some

guidance or good monitoring values to look at.

It is noticeable that this has only been tested on WW1900 A,B,E and WW2900 E appliances and is not

part of the software version.

Installation of monitoring extension: On the shell, install the matching package “srvadmin-snmp”:

[root@App4 ~]# yum install srvadmin-snmp

…

Is this ok [y/N]: Y <- confirm the above packages to be installed.

To enable SMUX support in Webwasher, please execute the following on the application CLI:

set global.SNMPAgent.SMUXEnabled 1

This will allow Webwasher to communicate with previously installed srvadmin module using the snmp

SMUX interface. An additional port will be opened locally on

tcp 0 0 127.0.0.1:199

The general concept is illustrated by the following graphic:
