Hybrid-Cloud-Observability Sample Questions & Answers

PerfStack (Performance Analysis dashboards) is the ideal tool for this requirement. It allows users to drag and drop various metrics from different monitored entities (nodes, interfaces, applications, etc.) onto a common timeline. This provides a powerful, time-correlated view to troubleshoot and analyze performance issues across different parts of the infrastructure.

The correct workflow is to first make SolarWinds aware of the vendor-specific OIDs by loading the MIB file into the MIB database. Once the MIB is loaded, you can create the Universal Device Poller and browse the MIB tree to select the correct OID. After the poller is defined, it must be assigned to the relevant nodes (the UPS devices). Finally, to visualize the collected data, you must add a resource like a chart or table to a view, such as the Node Details view.

Creating a comparative path from a different location with a different ISP is the most powerful troubleshooting step. If the second path does not show the same packet loss and latency at the same point, it provides strong evidence that the issue is isolated to the primary ISP's network. This comparative data is crucial for efficiently resolving the issue with the provider.

SolarWinds NTA provides granular control over data retention. To meet the specified requirements, the administrator should navigate to NTA Settings and configure the retention periods for different data types. They can set the detailed 'Conversation' data to be kept for 7 days while setting longer retention periods for less granular, summarized data like 'Endpoint' or 'Application' traffic, thus meeting the one-year trend requirement while saving significant database space.

This is a common issue in HA setups. When the secondary server becomes active, it attempts to send emails from its own IP address. If the SMTP server or an intermediate firewall has rules that only permit connections from the primary server's IP, the emails will be blocked. The solution is to either use a shared virtual IP for the HA pool and allow that VIP, or to explicitly allow the IP addresses of both the primary and secondary servers on the SMTP relay.

The Network Sonar Discovery wizard is the correct tool for this task. On the 'Import Preview' page of the wizard, after the discovery scan is complete, you can select the nodes to be imported. At this stage, there is an option to 'Set Custom Properties' for all selected devices before the import is finalized. This allows for the bulk assignment of properties like 'Branch_Code' efficiently.

The best practice for 'flapping' nodes is to adjust the alert's trigger condition. By adding a time-based condition, such as 'Node must be down for more than 10 minutes', the alert will only trigger for sustained outages, not for brief intermittent connection drops. This significantly reduces the number of events and alert notifications, allowing administrators to focus on genuine problems.

This scenario describes a classic large-scale, distributed deployment. A Main Polling Engine is always required as the core of the Orion instance. Additional Polling Engines (APEs) are needed in each remote continent to handle local polling. Enterprise Operations Console (EOC) provides the required 'single pane of glass' by aggregating data from multiple, independent Orion instances (which would be necessary for this scale and geographical separation) into one centralized view.

The Web-Based Report Builder is the primary tool for creating, customizing, and scheduling reports in the SolarWinds Platform. It has built-in capabilities to calculate percentile data (like 95th percentile) for metrics such as bandwidth utilization. Once a report is created, a schedule can be configured to automatically run it and email the results to stakeholders.

The correct parameter for the FlowStorage-Configuration.exe command-line tool to set the data retention period is --set-retention periodindays . This tool is used for advanced configuration of the NTA Flow Storage Database outside of the web console.
