Re: [wildfly-dev] JDBC stats, clarification needed
"Add count" and "miss count" are redundant attributes to me.
I think that only the "miss count" should be used since in cache terms this
is more commonly used and you will surely add them to cache in case of a
miss.

I am trying to make sense of the data source stats and need some help. Can
someone explain these figures to me? The hit count is smaller then the
access count. I would expect the other accesses to show up in the miss
count, but they don't. Is it a bug or do I misinterpret these numbers?
[standalone@localhost:9999 /]
/subsystem=datasources/data-source=ExampleDS/statistics=jdbc:read-resource(include-runtime=true)
{
"outcome" => "success",
"result" => {
"PreparedStatementCacheAccessCount" => "41",
"PreparedStatementCacheAddCount" => "6",
"PreparedStatementCacheCurrentSize" => "6",
"PreparedStatementCacheDeleteCount" => "0",
"PreparedStatementCacheHitCount" => "35",
"PreparedStatementCacheMissCount" => "0",
"statistics-enabled" => true
}
}
Regards, Heiko
