pdweb.sescache component

The pdweb.sescache component gathers statistics about the WebSEAL session cache. This component gathers the following activity information:

hit

The number of requests where a cache entry for a user was referenced successfully. That is, the number of requests that resulted in a session cache hit.

miss

The number of requests that missed a session cache hit.

add

The number of cache entries that was added to the session cache.

del

The number of cache entries that was deleted from the session cache.

inactive

The number of times where a cache entry hit the inactivity timeout.

lifetime

The number of times where a cache entry hit the lifetime timeout.

LRU expired

The number of times that a least recently used cache entry was deleted from the session cache to make room for a new cache entry.

The following example shows the output from a stats get command for the pdweb.sescache component:

pdadmin sec_master>  server task default-webseald-instance stats get pdweb.sescache
hit      : 225
miss     : 75
add      : 375
del      : 150
inactive : 60
lifetime : 15
LRU expired : 75

In the previous release, the pdweb.sescache component contained activity that was associated with callback certificates and user session mappings. These statistics are now managed by the following components:

pdweb.certcallbackcache

This cache stores the SSL IDs of sessions that require certificate validation when a user is stepping up. The reported information has the same categories as pdweb.sescache. These activities are internal.

pdweb.usersessidcache

This cache stores a mapping of users to their sessions. The reported information has the same categories as pdweb.sescache. These activities are internal.

Therefore, the first time that you gather statistics for the pdweb.sescache component and compare it to your last report, the figures might appear to be wrong. To set a new baseline, add the statistics from the following components and then compare them to your previous baseline (last pdweb.sescache report):

• pdweb.sescache
• pdweb.certcallbackcache
• pdweb.usersessidcache
