Alerting
Alerting is the heart of the monitoring system. NetCrunch triggers alerts receive, process and then executes actions in response to them
In this chapter
- External Event SourcesSee how to create an alert for Syslog messages, SNMP traps, Web Messages, and Windows Event Log entries.
- Alert Conditions & CorrelationNetCrunch alerts trigger proactive actions, not just notifications. They detect missing events and complex conditions while correlating events across nodes to enable tailored responses and automated remediation.
- Alert ViewsActive Alerts is one of the essential views showing current unresolved issues. NetCrunch tracks the state and correlates all internal events. When defining alerts for external events (SNMP, syslog, etc.), you can easily correlate by defining events that can close the alert.
- Alerting Actions and EscalationEach alert can have its own alert escalation script. This means that NetCrunch executes actions if the alert condition persists or can execute actions when the alert is closed.
- Receiving SNMPv3 NotificationsSNMPv3 uses a different notification model than previous SNMP versions. To receive SNMPv3 notifications, you need a proper authentication profile since they have to be decoded with a password and given encryption settings.
- Preventing False AlarmsLearn what situations increase alerts' volume and how NetCrunch helps prevent false alarms.
- Alert IntegrationsNetCrunch can easily integrate alerting with the external service desk, productivity, and messaging systems.
- Handling Repeating AlertsLearn how to handle alerts from devices or systems that keep sending them until the problem is resolved. This way, you get a single alert instead of hundreds of them.
- Predictive Analysis & AlertingForecast lists the monitored counters whose recent trend is heading toward a configured threshold, together with the date each one is expected to cross it. It turns NetCrunch's historical trend data into early warning, so you can deal with a disk that is filling up or memory that is leaking before it triggers a hard alert.
- Creating and Editing Alerting Rules in NetCrunchThis chapter provides a comprehensive guide on creating and editing alerting rules within NetCrunch. It covers the key properties that define an alert, such as Severity, Description, and Target State, and explores advanced configurations, including additional alerting conditions and automatic alert correlation. By understanding these concepts, network administrators can optimize monitoring strategies, reduce false positives, and ensure prompt and accurate incident responses.
