Patch Set 4: (2 comments) I think the example policy will have to be modified as well. And also the policy shipped with vdsm. http://gerrit.ovirt.org/#/c/34528/4/mom/Entity.py File mom/Entity.py: Line 101: """ Line 102: if (len(self.statistics) == 0): Line 103: raise EntityError("Statistic '%s' not available" % name) Line 104: total = 0 Line 105: nonEmptyStats = [x for x in self.statistics \ I agree with this. Line 106: if x.get(name, None) is not None] Line 107: for row in nonEmptyStats: Line 108: total = total + row[name] Line 109: if (len(nonEmptyStats) == 0): Line 106: if x.get(name, None) is not None] Line 107: for row in nonEmptyStats: Line 108: total = total + row[name] Line 109: if (len(nonEmptyStats) == 0): Line 110: return float(0) But I do not like this. This will cause the ballooning logic to see all zeros when no guest agent is available and I have no idea what will happen... I would prefer returning None here and conditionally checking it in the policy using: (if (valid guest.mem_total guest.StatAvg("field")) (do something)) Adding valid to Parser.py would be easy: def c_valid(self, *args): try: return not any(v is None for v in args) except TypeError: # some value is not null and not iterable return False Line 111: else: Line 112: return float(total / len(nonEmptyStats)) Line 113: Line 114: def SetVar(self, name, val): -- To view, visit http://gerrit.ovirt.org/34528 To unsubscribe, visit http://gerrit.ovirt.org/settings Gerrit-MessageType: comment Gerrit-Change-Id: I631056568b5a69e18f6ed02730c41ab59f460aad Gerrit-PatchSet: 4 Gerrit-Project: mom Gerrit-Branch: master Gerrit-Owner: Roy Golan <rgo...@redhat.com> Gerrit-Reviewer: Adam Litke <ali...@redhat.com> Gerrit-Reviewer: Martin Sivák <msi...@redhat.com> Gerrit-Reviewer: Roy Golan <rgo...@redhat.com> Gerrit-Reviewer: automat...@ovirt.org Gerrit-HasComments: Yes _______________________________________________ Engine-patches mailing list Engine-patches@ovirt.org http://lists.ovirt.org/mailman/listinfo/engine-patches
