---------------------------------------
Summary: DB performance impacted due to VM sync.
Key: CLOUDSTACK-8606
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8606
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server, Upgrade
Affects Versions: 4.5.0
Reporter: Koushik Das
Assignee: Koushik Das
Fix For: 4.6.0
VM sync. generates a lot of queries on vm_instance table with 'instance_name'
as filter. Since the field is not
indexed, these kind of queries will impact DB performance.
The issue is visible with deployments having more than 4000 VMs. VM sync. runs
every 'ping.interval' and in each run generates individual queries for all VMs.
If the MS is left running for a few hours, its response deteriorates
drastically.
