Figure 34-61. Configuration > SNMP page Proxy Cache tab
ZoneRanger can be configured to cache (store) previous SNMP responses to be used for
subsequent SNMP requests within a particular time period. The SNMP Proxy Cache Enabled
checkbox enables this capability.
The SNMP Proxy Cache Logging levels are:
Log Level
None
Short
Long
This SNMP Proxy Cache log can be downloaded by the downloadFile command on a
Ranger Gateway. The log file is called /log/snmpProxyCache.log . The log file may also
be viewed on the View > Service Logs page.
The Caching Settings section allows for the creation of rules to indicate which addresses
should have their SNMP responses cached based on the following information:
Setting
OID
Cache
Time to Cache
Time Units
If an OID in the SNMP request matches more than one entry then the first entry in the table that
it matches is used. Thus if a more specific OID entry is meant to override a less specific entry
then the more specific entry should be listed first. For example to cache all of the System table
except for sysUptime then first add an entry for OID .1.3.6.1.2.1.1.3 set to not cache and then
add one for .1.3.6.1.2.1.1 set to be cached.
