For information on monitoring the disk use through the vSphere Appliance Management Interface, see

Configure alarms
Alarms specific to
/storage/seat and
/storage/log partitions filling up were introduced in vCenter Appliance 6.7.
- In the Hosts and Clusters view, select the vCenter Server.
- Select the Configure tab > Alarm Definitions, > Log Disk Exhaustion, then the EDIT link to configure the thresholds.
- If you wish to send email alerts/SNMP messages, select to Send email notifications and Send SNMP traps:
Email alerts from vCenter
You can configure alarms to email out from vCenter when there is a warning or critical state, see
Configure Mail Sender Settings.
Manage Statistics Level
You can manage the statistics level by doing the following:
- In the Hosts and Clusters view, select the vCenter Server object.
- Select the Configure tab, Settings > General, then the EDIT link to configure what statistics level to use:
Note: It is highly recommended by VMware to keep statistics level at level 1 unless a higher level is required by a third-party product. Setting the level too high can lead to the /storage/seat partition filling up causing vCenter Server stability issues.
Default Retention Policy
A "retention policy" sets the thresholds for automated cleanup for events and tasks. This largely affects how full the
/storage/seat partition gets.
vSphere 6.7 defaults are to have the policy enabled, with a retention period of 30 days.
For effects of upgrades to vCenter Server versions, see
The default database retention policy in VMware vCenter Server 6.0To change the retention policy, see
Configure Database Retention Policy ,
Burst Event Feature
Starting with vCenter Server 6.7 Update 1, the vCenter system automatically compresses events that are similar. This feature assists with keeping events from overwhelming the database.
Events are similar if they meet three conditions:
- Equal event type
- Associated with the same user
- Associated with the same entitry (ESXi host, virtual machine, etc...)
Up to a 3600 event burst will go into a single compressed event message. This compression is enabled by default.
Burst compression can be configured for syslog
- In the Hosts and Clusters view, select the vCenter Server object.
- Select the Configure tab, Settings > Advanced Settings, then the EDIT SETTINGS
- Set the vpxd.event.burstFilter.compressToSyslog to true
