SNMP MIB walking and debugging SNMP sensors

You can log SNMP get requests that are sent by the sensors.

To do so, add the following property to the collation.properties file:

com.collation.Discover.jvmargs=-Xmx2048M 
-Djava.nio.channels.spi.SelectorProvider=sun.nio.ch.PollSelectorProvider
-Dcom.collation.platform.snmp.SnmpPackedPDU.trace=true 

You can then compare entries in the log file output with direct SNMP queries you run against the devices using snmpwalk. You can download SNMP query tools that support snmpwalk from http://www.net-snmp.org/download.html.

If SNMP V3 authentication is used with encryption, you must also download OpenSSL from http://www.openssl.org/.

The following example shows identical queries, with the first using V3 authentication (although the keys have been removed) and the second using community string authentication:

snmpwalk -v 3 -u cmdbadmin -l authPriv -a MD5 -A "my authentication password" 
   -x DES -X "my encryption key" 10.199.250.9 .1.3.6.1.2.1.4.20.1 
snmpwalk -v 1 -c 5FFGkFaFNs 10.199.250.9 .1.3.6.1.2.1.4.20.1
