vCenter Server Appliance (vCSA) reports errors similar to: vSphere UI Health Alarm", "Log disk exhaustion on vcenter nameDatabase Health Alarm", "Core and Inventory Disk Exhaustion on vcenter name vCenter Server may be inaccessible with 503 Service Unavailable errors.vSphere Appliance Management Interface (VAMI) Monitor > Disk shows /storage/log at 75% full or more: At 75% of continuous disk use the space will trigger Yellow status warningsAt 85% the space will trigger Red critical alarmsAt 95% the vpxd service will shut down to prevent file and database corruption
This article provides information on how to troubleshoot and resolve the /storage/log partition being full on vCenter Appliance.
Potential causes include: vCenter Server log bundles not being cleared after generationVery high frequency events filling up logsServices such as the Apache Tomcat Java Servlet service failing to clean up files/storage/log partition set too small
Under default settings, when the partition reaches 75% full of continuous disk use for at least 10 minutes: You will see alarms being triggered. When the partition reaches 95% full at any point The operating system will prevent the main vmware-vpxd service from starting to try to prevent file corruption. Please keep in mind that this does not require it to be at 95% for a continuous period so the threshold might be crossed, shut down vpxd service, and then the use may recede,Deleting critical files may prevent the vCenter Server Appliance from working.Resizing vCenter Appliance virtual disks carries the risk of data corruption. WARNING: Ensure you have a good backup of vCenter Appliance before deleting files or resizing disks.
