Analyze Host I/O Trend Over Time

To view I/O activity across all Ops Insights enabled hosts, click I/O under Resources in the left navigation menu.

By default, you view comprehensive I/O activity for each host. Viewing the I/O activity for each host lets you compare resource utilization between hosts and identify servers with underused or overused resources. For each host, you view the following:

• Host Display Name: The display name of each host enabled for Ops Insights
• Compartment: Compartment location of the server.
• Platform Type: The following platforms are supported:
  • Linux (including Ubuntu)
  • Solaris
  • Windows
  The following platforms are supported through hosts monitored by Enterprise Manager only:
  • zLinux
  • AIX
  • HP-UX
  To add Enterprise Manager targets into Ops Insights see: Adding Enterprise Manager Targets.
• Usage (MB/sec): Amount of server usage expressed in megabytes per second
• Usage Change (%): Total delta percentage usage change in a selected host
• Read (MB/Sec): Amount of server read usage expressed in megabytes per second
• Write (MB/Sec): Amount of server write usage expressed in megabytes per second

I/O charts analysis and usage are similar to those used elsewhere in the Capacity Planning application. For an in-depth discussion about Capacity Planning charts, see:

• Insights Table
• Trend and Forecast Chart
• Compare CPU Utilization Between Databases

Analyze Trend and Forecast I/O Usage

Selecting a host from the I/O usage (Insights) table, you can view I/O utilization as well as the trend and usage forecast for that host. Alternatively, you can also specify the breakdown by Mountpoint to view trend and forecast analysis for all filesystems running on that host.

By default, trending and forecasting are calculated using linear regression. For more advanced analysis, you can have Ops Insights use machine learning to perform the trending and forecasting.

Under Forecast Settings you can change range for the forecast period.
