|Issue||AxM: How do I use the cache data from SNMP to tune the aserver cache values?|
aserver performance tuning
When you browse each of the 14 caches viewable from the MIB, statistics are available for each cache type in the aserver. Most of the cache sizes can be tuned by retrieving the data from the Instrumentation server using SNMP and using the table above to adjust the corresponding cache size.
To improve the cache hit ratio, increase the cache ttl and/or the cache size. Increasing the cache size will only be effective if the maximum size of the cache as specified in aserver.conf has been reached. Increasing the cache ttl will cause the cache size to increase and may require an increase to the cache size to be effective. The token cache ttl is controlled by the aserver.conf parameter cleartrust.aserver.token.cache.ttl (default 15 minutes - it should match the idle timeout of the agents). Other caches are controlled by the parameter cleartrust.aserver.cache.time_to_live (default 5 minutes).
