Change subject: core: Removing reschedule of monitoring of vdsm by another vdsm ...................................................................... core: Removing reschedule of monitoring of vdsm by another vdsm The following patch will remove a reschedule of monitoring of vdsm, from other thread of monitoring. Such behaviour can cause to spending all quartz thread on reschedule of monitoring of the same vdsm. The use case: 1. We have 10 vdsms and 10 vms that are migrating to same vdsm 2. Each vdsm can schedule additional refresh of destination vdsm 3. Result : we has 10 quartz jobs that are trying to monitor the same vdsm and additional job which is regular monitoring (runs each 2 seconds) It is obvious that under load and in more big environment we will have a timeouts when all quartz threads will be busy by monitoring of the same vdsms Change-Id: I5534b3b627e992efbce152935ad207c978a7feed Signed-off-by: Michael Kublin <mkublin(a)redhat.com&gt; --- M backend/manager/modules/vdsbroker/src/main/java/org/ovirt/engine/core/vdsbroker/VdsManager.java M backend/manager/modules/vdsbroker/src/main/java/org/ovirt/engine/core/vdsbroker/VdsUpdateRunTimeInfo.java 2 files changed, 4 insertions(+), 37 deletions(-) Approvals: Michael Kublin: Verified; Looks good to me, approved -- To view, visit http://gerrit.ovirt.org/8483 To unsubscribe, visit http://gerrit.ovirt.org/settings Gerrit-MessageType: merged Gerrit-Change-Id: I5534b3b627e992efbce152935ad207c978a7feed Gerrit-PatchSet: 2 Gerrit-Project: ovirt-engine Gerrit-Branch: master Gerrit-Owner: Michael Kublin <mkublin(a)redhat.com&gt; Gerrit-Reviewer: Eli Mesika <emesika(a)redhat.com&gt; Gerrit-Reviewer: Michael Kublin <mkublin(a)redhat.com&gt; Gerrit-Reviewer: Omer Frenkel <ofrenkel(a)redhat.com&gt; Gerrit-Reviewer: Roy Golan <rgolan(a)redhat.com&gt; Gerrit-Reviewer: Yair Zaslavsky <yzaslavs(a)redhat.com&gt;
