When creating a new JMX measure, there are 5 different variations : Byte Measure, Measure, Percentage Measure, Rate Measure and Time measure.
The only documentation I found is
Using Custom JMX and PMI Measures in Charts which does not explain these variations...
Where can I find more about this ? or can someone explain it here ?
Hi Silvain. I am happy to discuss this question tomorrow during my next online perf clinic - http://bit.ly/onlineperfclinic
But basically it is just how dynatrace captures the value and makes it available to the time series engine of dynatrace. Certain Measures exposed via JMX dont necessarily have a type information. With these different variations you can say that the value for the JMX Measure is for instance indicating "Bytes" as in "Transfered Bytes". Or a Percentage Measure would indicate a value between 0 and 100 that dynatrace will by default display as a % value. Makes sense?
I assume those are JMX attributes provided by Tomcat's JDBC Connection Pool MBean.
If so, it's probably a bit off-topic discussing the meaning of those values here but my personal understanding would be as follows:
The total number of connections borrowed from this pool.
The total number of available (non-borrowed) connections in this pool.
The currently set timeout (probably in ms) for when an idle borrowed connection is returned to the pool.
