Managing the Behavior and Performance

You might want to change various settings for the VMware Skyline Health Diagnostics appliance for better user experience and performance. The configuration settings are now available in the user interface.

Only shd-admin user or users with the administrative privilege can modify the properties from the VMware Skyline Health Diagnostics user interface.

Configuration Properties	Description
Log File Size	This property indicates the maximum allowed file size for Skyline Health Diagnostics logs. If the size of the logs exceeds this value, the logs are overwritten. Note the value is specified in Megabyte (MB).
Log File Count	This property indicates the number of Skyline Health Diagnostics log files that will be retained after log rotation.
Password History	This property indicates the number of saved passwords that were used previously. Note: You cannot reuse any of the saved passwords.
Password expiry (in days)	This property indicates the duration (in days) for which a password can be used. Beyond this period, the UI authentication will fail. You can set the value as 90 or 180 days.

Number of Log Indexers	This property specifies the number of log indexers deployed for log indexing. The log indexer helps to index the logs. Faster indexing results in faster log analysis and report generation. The recommended number of indexers value is n-1, where n is the number of vCPUs of the VMware Skyline Health Diagnostics virtual machine. As the default number of vCPUs for the appliance are four so, you keep the value to three.
Number of Log Extractors	This property specifies the number of log extractions that can run in parallel.
Log Generation Timeout	This property is used during the log collection phase of the analysis operation, it specifies duration in minutes for which analysis waits for log bundle generation to complete. The value being 0 indicates no timeout.
Log Download Timeout	This property is used during the log collection phase of the analysis operation, it specifies duration in minutes for which the analysis workflow waits for log bundle download to complete. The value being 0 indicates no timeout.
Log Extraction Timeout	This property used during the log extraction phase of analysis operation; it specifies duration in minutes for which the analysis workflow will wait for log bundle extraction to complete. The value being 0 indicates no timeout.
