We have a measure for JDBC Connection Pool Percent used. We have an alert trigger at anything over 90% usage. Strangely enough, some of those alerts have been triggered with a usage of 104%.
How is it possible to have usage greater than 100% for that metric?
Also, when it measures the percentage, is that for the JVM connections, or is it for the entire database?
Thanks in advance.

Is it possible that someone changed the size of the pool during this timeframe?
The pool size is for the JDBC connection pool (generally) inside the JVM where the agent resides. This is not the pool size within the database itself.

Thanks for the response. The second portion clears up that aspect.
Now, I was told that the pool size did not change during that or any time period close to it. This is our Production environment, so I wouldn't have assumed it changed, but I checked to make sure.
Any other thoughts on possibilities?
