Another update.

 

 

The use of this monitor in a production environment has highlighted a limitation in the use of Database monitors on the BigIP. as the DBDaemon function is java and the max heap is 64Meg, running more than 10-15 of these monitors concurrently creates unpredictable behaviour (monitoring the java process shows it memory usage hitting the ceiling)

 

 

Has anyone written any other monitors or come across this problem?

 

 

I'm going to log this with support, and look at writing an alternative monitor.

 

 

Thanks
