opEvents

Cut Alert Noise by Orders of Magnitude, Find Root Cause Before the Outage Escalates

opEvents ingests syslog, SNMP traps, and Windows events from your entire network, applies intelligent correlation and deduplication, and surfaces only the events that matter. Stop drowning in alerts, resolve incidents faster and prove the cause within seconds.

In The Product

323 events in two hours, and the shape of them

opEvents 4.6.5Events by Node
opEvents Events by Node view, with a pie chart apportioning events across the ten noisiest nodes beside a stacked area chart of event volume over two hours, above a colour-coded event table listing date, node, event, element, count, priority, state, group and location
The same two hours read three ways. The pie names the noisiest nodes, the stacked area shows when the volume arrived, and the table below is coloured by state, so closed events turn green and stop competing for attention.

Architecture

opEvents Architecture

Event ingestion through to NMIS fault context, correlation and policy enforcement at every stage of the pipeline.

Capabilities

From Raw Syslog to Actionable Intelligence, Automated Event Processing at Scale

From raw syslog to actionable insights, opEvents transforms your event data.

Syslog Aggregation

Collect and normalise syslog messages from every device on your network. opEvents processes high-volume syslog streams in real time with configurable parsing rules.

SNMP Trap Processing

Receive, decode, and correlate SNMP traps from any device. Map traps to actionable events with customisable severity classification and escalation rules.

Windows Event Support

Collect Windows Event Log entries alongside network events. Unified visibility across Linux, network, and Windows infrastructure in a single event stream.

Intelligent Correlation

Automatically correlate related events across devices and time windows. Reduce hundreds of individual alerts into a single root cause event, dramatically cutting alert noise.

Alert Deduplication

Prevent alert fatigue by automatically deduplicating repeated events. See the first occurrence, the count, and the last occurrence, not hundreds of identical notifications.

Policy-Based Actions

Define automated response policies triggered by specific event patterns. Execute scripts, send notifications, create tickets, or escalate to on-call staff automatically.

Triage

From a list of events to one cause

Two clicks. The list tells you where to look, and the context page has already done the first round of diagnostics.

opEvents 4.6.5Events
opEvents event list showing 281 events over two hours, each row coloured by state, with green rows for services and nodes returning up, orange rows for services and nodes going down, and amber rows for open proactive CPU and baseline alerts
Every row is coloured by state rather than by severity alone. Recovered services go green and settle, open faults stay orange, and proactive baseline alerts sit amber between the two, which is how a shift lead reads a screen at a glance.
opEvents 4.6.5Event Context
opEvents Event Context page for an STM alarm notification, showing the decoded SNMP trap detail and node facts on the left, related events and a table of six automated actions on the right, and the captured output of an automatic ping script at the foot of the page
Opening an event shows what opEvents already did about it. Here a trap arrived, six actions fired, priority was raised to 8, and a ping ran and returned in four seconds, all before anyone looked. The engineer starts from a result, not a raw trap.

NMIS Ecosystem

How opEvents integrates with NMIS

NMIS Fault Context

Every event is enriched with NMIS device context, node health, group membership, and business classification. Know the impact of an event before you even investigate.

opCharts Visualisation

Display event status alongside performance charts in opCharts. Click from an event to the affected device's performance history for faster root cause analysis.

Ticketing & Notification

Integrate with your existing ITSM platform. opEvents can create and update tickets, send emails, trigger webhooks, or execute any command-line action.

Built For Your Team

Who uses opEvents

NOC & Operations

Cut through the noise

Correlation and deduplication reduce hundreds of raw alerts into actionable events. Your NOC focuses on real problems, not repeated symptoms.

  • Correlated root cause events
  • Automated deduplication
  • Severity-based escalation
Network Engineers

Faster root cause analysis

Trace events across devices and time. opEvents shows you the sequence of events that led to an outage, not just the final symptom.

  • Cross-device event correlation
  • Timeline-based investigation
  • SNMP trap decoding
IT Management

Measurable noise reduction

Demonstrate operational improvement with event metrics. Track mean time to detect, alert volumes, and correlation effectiveness over time.

  • Event volume trending
  • MTTD improvements
  • Policy effectiveness reporting

Take control of your network events

opEvents is included in the FirstWave VM alongside NMIS and other commercial opModules.
