SLA - Release Notes

Version 1.0.2-1

Intro

SLA stops and starts appliances within the application in response to varying performance and resource data provided by the MON appliance.

Changes

• v.1.0.2-1 changes since v.1.0.0-1
  1. changed php.ini not to log notices
  2. changed the graph to normalize requested pixel widths such that the number of counter values per pixel is always an exact integer (at 3840 px wide, there was a fractional error causing the graph to skew slightly from the scale)
  3. changed existing sanity check to delete the policy (not just raise an error) if there is a mismatch between the appliances listed in the policy and the appliances found in the application. This is necessary in case a user manually adds to or removes appliances from the appliance group while the application is stopped. A dashboard message is also created advising the user to re-define the policy.
  4. re-sized the /usr volume
  5. Changed the .png in the header of the GUI to display "SLA"
  6. changed dashboard message generation not to repeat messages:
     • If counter collection fails for > 1 minute, a message is created. It is not created again in the same circumstance until in the interim counter collection has succeeded.
     • If all appliances in the group are running but start_condition is true, a message is created. It is not created again in the same circumstance until in the interim not all appliances are running.
     • If all appliances in the group are stopped, a message is created. It is not created again in the same circumstance until in the interim not all appliances are stopped.
