Issue/Introduction

How to obtain the CPU utilization, hard disk utilization and memory usage through SNMP polling.

Resolution

To extend the Bluecoat Security Analytics MIB functionality to include polling for CPU Utilization/Load, Hard disk utilization, and Memory Usage, you may enable the generic MIB module Host-Resource-MIB and UCD-SNMP-MIB.
 
Please follow the procedure below to enable the MIBs,
 

1. Make sure that SNMP polling is enabled in the GUI under Settings > Communication and click Save.

          
 

2. Edit the /etc/snmp/snmpd.conf file using vi and find the section that describes the capabilities of the 'soleraview', and add the lines (in bold) as shown below,

[root@hostname ~]# vi /etc/snmp/snmpd.conf
# Make at least  snmpwalk -v 1 localhost -c public system fast again.
#       name           incl/excl     subtree         mask(optional)
#view    systemview    included   .1.3.6.1.2.1.1
#view    systemview    included   .1.3.6.1.2.1.25.1.1
view    soleraview     included   .1.3.6.1.2.1.1
view    soleraview     included   .1.3.6.1.2.1.2
view    soleraview     included   .1.3.6.1.4.1.30190
view    soleraview     included   .1.3.6.1.2.1.25
view    soleraview     included   .1.3.6.1.4.1.2021
# Solera View : SNMP MIB-2 System +  SNMP MIB-2 Interfaces + Solera Enterprise MIB

 

3. Restart the snmpd services to enable the changes.

[root@hostname ~]# service snmpd restart
Stopping snmpd:                              [  OK  ]
Starting snmpd:                              [  OK  ]

 
Once the MIB is enabled, you can confirm whether the appliance is responding to the new snmp settings by using this command from a workstation:

snmpwalk -v 1 -c public ip_address .1.3.6.1.2.1.25

or

snmpwalk -v 1 -c public ip_address .1.3.6.1.4.1.2021

Please refer to the attachment for examples for polling Blue Coat Security Analytics Platform CPU Utilization/Load, Hard disk utilization, and Memory Usage via MIB.  

Note:  To enable this configuration to persist even when the GUI changes Blue Coat specific content, edit the /etc/snmp/snmpd.conf.tmpl file with the same changes.
