Performance
In the Performance tab, you can view performance of an appliance at a glance. There are multiple performance metrics like CPU, Memory or Network Write, that you can select to evaluate the performance of the selected appliance(s).
Performance tab is only available for the following appliances:
NetBackup Flex Scale appliances version 2.1 and above
Access appliances version 8.0 and above
Flex appliances version 2.2 and above
NetBackup appliances 3.2 and above
Available performance metrics in System Health Insights are:
Metric | Description | Unit |
|---|---|---|
CPU | This metric identifies CPU usage for jobs and processes. | % |
Memory | This metric identifies memory usage for jobs and processes. | % |
Disk Write | This metric identifies bytes written from store volumes available to the appliance. | MB/s |
Disk Read | This metric identifies bytes read from store volumes available to the appliance. | MB/s |
Network Write | This metric identifies the volume of outgoing network traffic from a single appliance. | MB/s |
Network Read | This metric identifies the volume of incoming network traffic on all network interfaces for the appliance. | MB/s |
NetBackup Active Jobs | This metric calculates number of NetBackup active jobs at the specific time. | MB/s |
Overall NetBackup deduplication ratio | This metric calculates average of dedupe ratio for last 24 hours | % |
You can perform following actions in the Performance tab:
Select Node which you would like to monitor .
Select one or more Performance Metrics for accessing performance of the node. You can also rearrange or remove the metrics as per your usability. Your arrangement will be persisted for the selected node.
Enable Anomaly Detection. If you enable anomaly detection, multiple algorithms are applied to continuously analyze the metric data received from the appliance(s). The algorithms identify baselines and generate a range of expected values, which are depicted by bands that appear on the graphs. It will help you in identifying instances when the actual value exceeds the expected range.
Select High Level Metric. The selected metric will appear at the top of the chart. You can double click and select a specific area in the chart. The selected specific area will be highlighted and stored. Your selection will be persisted for the selected node.
Change the zoom level by selecting the option like 1D or 1W. Data for the selected period will appear on the page.
You can zoom the graph by drawing a square around the desired time-slot or by adjusting the zoom utility on the page. To zoom out, click Reset Zoom.
Export all the performance data for the selected date range, nodes, and metrics in CSV or PDF format, by clicking the kebab menu in the top right corner of the page.
Note:
Data for last 6 months will be available for all the metrics.
To know granular details in metrics at a specif time, hover over the chart. A detailed information message will appear on the screen which will have all the relevant information about all selected metrics at the given time.
