Validate Gauge Indicator Values in SevOne Reports

Steps

This article explains how to validate gauge indicator values displayed in SevOne reports to ensure they accurately reflect the data collected by the system.

To begin, create an Instant Graph using the indicator you want to validate. This can be done by selecting the Instant Graphs option under the Reports menu in the NMS. In the Instant Graph settings, choose the appropriate device, object, indicator type, and time span as required.

Please note that from version 8.0.0 onwards, the same Instant Graph can also be generated in SevOne Data Insight using the Instant Graphs option.



Next, verify whether the selected indicator is of the Gauge type. This can be done under Administration → Monitoring Configuration → Object Types. Search for the relevant object type and click the Edit Indicator option. The indicator details will specify whether it is a Gauge type.



Once confirmed, generate the Instant Graph by clicking Draw Graph. For example, the graph below was created for the CPU Load indicator over a one-hour time span with a polling frequency of 300 seconds (five minutes).



Before validating the results, ensure whether the De-normalizing GAUGE Totals setting is configured or not. This option is available under Cluster Manager → Cluster Settings → Graphs. When this setting is enabled, SevOne performs total aggregation for the graph summaries. When it is disabled, the system uses a simple sum for the total column.



After verifying the settings, export the CSV data from the generated graph. This can be done by detaching the graph and selecting Get CSV from the edit options. The downloaded CSV file contains the polled data used to plot the graph.



The CSV data which was exported is shown below:



For gauge-type indicators, SevOne plots the exact values as they are received from polling. The CSV output reflects these raw values, which are then used to derive the average, minimum, and maximum using standard formulas.


In the example reviewed, the average, minimum, and maximum values were 29.25, 15, and 61 respectively. These values match the data displayed in the Instant Graph, confirming that SevOne accurately represents gauge indicator values in its reports. This validation process helps ensure that the data displayed in SevOne reports can be trusted for accurate analysis.
