| Term | Definition |
|---|---|
| Advanced Reports | Advanced Reports in OpManager are customizable, multi-parameter reports that provide comprehensive insights by allowing users to select, filter, group, and export monitoring data as needed. |
| Alarm | An alarm is an alert notification that is used to notify the user when a threshold violation occurs. |
| Alarm Correlation | Define multi-criteria rules (based on device, severity, time window) that group related alarms into a single correlated incident, reducing noise and surfacing the root problem. |
| Alarm Suppression | Temporarily mute alarms for selected devices, interfaces, or monitors, manually or via workflows, so no alerts fire during scheduled maintenance windows. |
| Agent | Agent is the small executable file installed in a remote Windows device to monitor it. With agent-based monitoring, OpManager need not use its server resources to poll the remote device every time. The agent monitors the device and sends data to OpManager. |
| APM Plugin | This refers to the Application Manager plugin. By downloading and installing this plugin in OpManager, you can monitor applications, servers, and databases in your network. |
| Authentication | Supports local login, LDAP/AD, RADIUS, OAuth, and SAML. Two-Factor Authentication (via TOTP or email OTP) can be enforced for any or all roles. |
| Audit Logs | Comprehensive, chronological reports of all user actions, configuration changes, API calls, and data collections, providing full accountability and compliance tracking. |
| Business Views | A visual representation of the arrangement of devices in your network. |
| Central | It gives a centralized view of the monitoring data collected from Probes installed in various network sites. |
| Custom Fields | A user-defined field that allows you to add specific details about a device or interface apart from the existing ones, such as a Service Tag. This appears on the snapshot page of a device or interface. |
| Custom Integrations | Build bespoke API or webhook integrations, specify endpoint URLs, authentication schemes, and payload mappings, to connect OpManager with tools not supported natively. |
| Dashboard | Gives a complete overview of your entire network through customizable widgets and layouts. |
| Database Backup | Includes the BackupDB scripts (Windows/.sh) and SQL dump procedures to export your OpManager configuration, historical metrics, and logs, ensuring you can restore data after upgrades or failures. |
| Device Snapshot/Summary Page | The page that opens when you click a device under the Inventory tab. It provides availability, health, and detailed performance stats of a device. |
| Device/Interface Templates | Device Templates are predefined profiles containing device-specific details such as type, category, monitoring interval, SysObject ID, and performance monitors, which OpManager uses to automatically identify and configure devices during discovery. |
| Device Categories | Default buckets (Routers, Switches, Servers, Storage, UPS, etc.) assigned based on discovered credentials; categories let you apply thresholds, reports, dashboards, and filters en masse. |
| Discovery | The process of adding a device or interface in OpManager for monitoring. |
| Discovery Filter | Include or exclude IP ranges, device types, or categories from each discovery job, so only relevant devices are added or existing ones ignored. |
| Discovery Rule Engine | Lets you define rule-based actions (e.g., add monitors, notification profiles) that automatically apply to matching devices during network discovery, so new devices are fully onboarded without manual steps. |
| Forecasting Alerts | Uses historical MIN/MAX/AVG performance data plus a built-in forecast engine to predict resource exhaustion (disk, SQL logs, datastores) and raise proactive alerts when thresholds are projected to breach. |
| Groups | Groups help you organize multiple devices or interfaces to push bulk configurations. |
| Integrations | Out-of-the-box connectors for popular ITSM and collaboration platforms (ServiceDesk Plus, ServiceNow, Jira, Slack, Teams) that let alarms automatically generate tickets or notifications. |
| Interface templates | Interface Templates are predefined configurations that categorize device interfaces by type and associate the appropriate performance monitors and thresholds across all matching interfaces in the network. |
| Inventory | After discovery, all devices and interfaces appear under the Inventory tab. VLANs, subnets, VMs, IP SLA monitors, and storage devices are listed under their respective sections. |
| Mail Server/SMS Server | Configure external SMTP and SMS gateway settings so OpManager can send emails, SMS alarms, forecast alerts, and Two-Factor OTPs. |
| Migration | The comprehensive Upgrade & Migration guide covers backing up your database, using the Update Manager, and pushing updates via Smart Upgrade to move your Central and Probe servers across versions or hardware with minimal downtime. |
| Monitor | A monitor refers to the metric used to measure device or interface performance (e.g., CPU Utilization). |
| Network Path Analysis | Traces hop-by-hop paths between nodes, displaying latency, packet loss, and device status at each node to reveal bottlenecks or failures. |
| NOC View | Create a NOC (CCTV) view by selecting multiple custom dashboards. This alternates selected dashboards at regular intervals for central monitoring by your NOC team. |
| Notification Profile | This feature allows you to configure criteria and the notification channel to send alarm details from OpManager. |
| Polling Interval | The time period between any two consecutive polls. |
| Ports | OpManager uses various TCP/UDP ports to discover and poll devices, receive traps, serve the web UI, and support add-ons (e.g., SNMP 161, Trap 162, Web 8060, NetFlow 9996). |
| Probe | The monitoring agent installed in a remote network site to monitor the network and send data to the Central server. |
| Rebranding | This option helps you change OpManager’s default logo to your organization’s logo. |
| Re-Discovery | The process of rediscovering an existing device or interface to update newly added details such as name, type, and disk space. |
| Reports | A database of monitoring statistics of your network devices and interfaces, primarily useful for future analysis. |
| Report Builder | The multi-criteria Report Builder lets you select devices, monitors, and time ranges, then save, schedule, and export reports as PDF/XLS. |
| Root Cause Analysis | A unified view that overlays metrics across devices, interfaces, and URLs in one pane to pinpoint the originating trigger of network issues for faster troubleshooting. |
| Severity / Threshold | Refers to how serious the issue is. Attention, Trouble, and Critical are the three levels of severity. |
| Smart Group | Dynamic device collections that automatically include/exclude devices based on real-time criteria (vendor, IP range, custom fields), keeping groups up to date as your network changes. |
| SNMP Trap | A trap is a message sent from the agent on a monitored device to OpManager when a fault or network issue occurs. |
| Syslogs | OpManager’s Syslog Daemon listens on port 514 (and any additional ports configured), applies rule-based filters, and converts matching log messages into alarms or notifications. |
| Vendors | OpManager recognizes device manufacturers (Cisco, Juniper, HPE, Dell, etc.) by OID and firmware signatures to select the appropriate device template and polling protocol. |
| Widgets | A widget is a window inside the dashboard displaying specific information (e.g., Recent Alarms, Devices by Utilization). |
| Workflows | Drag-and-drop sequences of actions (acknowledge/suppress alarms, log tickets, run scripts, etc.) triggered by alarms or schedules, automating routine remediation without scripting. |
| User Roles | OpManager defines three built-in roles Administrator (full access), Operator (view-only), and Custom (user-configured), each controlling which modules, device groups, and actions a user can perform. |
