Millions of JDBC connections recorded #371

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Hello, not sure if this is an issue or a configuration question, but my active 
JDBC connections and used JDBC connections graphs are showing peaks of hundreds 
of millions of JDBC connections, which can't be right.

The database is configured for a max. of 100 simultaneous connections and SQL 
hits per minute top out at about 2,000. 

The SQL stats for today so far show '58 hits/min on 776 requests'.

Am I mis-understanding the JDBC graphs, or do you think is there some sort of 
reporting error? I attach all relevant graphs from the homepage.

As said in the "online help" for graphs units:
"m" is for milli (1 / 1000), "k" is for kilo/thousands, "M" is for 
mega/millions, "G" is for giga/billions and "u" is for micro (1 / 1000000)

So in a RRD graph, 8m means 0 most of the time and sometimes 1.
