Hi Stefan,
I only received the mail from the daily summary?
There is only one application that use Gluster.
1) Before I started the application, I requested the statistics.
So the next time I will request the statistics, I will see what is happened between the 2 statistics requests.
2) I start the application and wait until it is completely started.
3) I request the statistics again.
Vriendelijke groeten,
Cordialement,
Best regards,
Stijn Van Renterghem
