Monitor application performance using alerts

Monitor application performance using alerts

• About application alerts

• Identify application services with health issues

• Identify application service performance issues

• Virtual server status events
  Virtual Server events and indicate the status of the virtual server and its pool. You can see these events and alerts in the charts of the application properties screen ( Applications > APPLICATIONS > <Application Name> > <Application HTTP Service>) and in the Local Traffic dashboards ( Monitoring > DASHBOARDS > Local Traffic). You can also view alerts in the Active Alerts and Alert History screens (Applications > ALERT MANAGEMENT).

• Wide IP status events
  Wide IP events and indicate the status of your DNS pools of virtual servers, and the overall health of your DNS application services. You can see these events and alerts in the charts of the application properties screen ( Applications > APPLICATIONS > <Application Name> > <DNS Application Service>) and in the DNS dashboards ( Monitoring > DASHBOARDS > DNS > GSLB). You can also view alerts in the Active Alerts and Alert History screens (Applications > ALERT MANAGEMENT).

• Pool member status events
  Pool member events and alerts indicate the status of a pool member. You can see these events and alerts in the charts of the application properties screen (Applications > APPLICATIONS > <Application Name> > <Application HTTP Service>) and in the Local Traffic dashboards (Monitoring > DASHBOARDS > Local Traffic). You can also view alerts in the Active Alerts and Alert History screens (Applications > ALERT MANAGEMENT).

• HTTP Application service alerts
  HTTP application service alerts notify regarding changes in metrics that can affect the overall performance of traffic or security management for your managed application. When one or more of these thresholds are crossed, the health of your HTTP application service will change. You can view alerts from the single application service’s screen (Applications > APPLICATIONS > <Application Name> > <HTTP application service>), or the alerts screens (Applications > ALERT MANAGEMENT > Active Alerts or Alert History).

• TCP application service alerts
  TCP application service alerts notify you when there are changes in metrics that can affect the overall performance of traffic over the network. There are no default alert thresholds for TCP application services, so you must configure your threshold values to receive alerts. If configured, you can view alerts from the application service’s screen (Applications > APPLICATIONS > <Application Name> > <TCP application service>), or the general alerts screens (Applications > ALERT MANAGEMENT > Active Alerts or Alert History).

• Web Application Security Alerts
  Security alerts in the TRENDS AND IMPACTS area of the L7 Security dashboard (Monitoring > DASHBOARDS > L7 Security) notify you of the number of objects reporting Web Application Security policy (Web Exploits) or DoS profile (L7 DDoS Attacks) events over the past day (trend charts report the past week). These alerts indicate that a protected object (application or virtual server) recently experienced an increased rate in performance issues. To view data the corresponds with these traffic events go to Monitoring > DASHBOARDS > DDoS > HTTP Analysis To view the status of your deployed applications, go to Applications > APPLICATIONS.

• DNS application service alerts
  DNS application service alerts notify you when there are changes in metrics that can affect the overall performance of traffic over the network. When one or more of these thresholds are crossed, the health of your DNS application service will change. You can view alerts from the application service screen (Applications > APPLICATIONS > <Application Name> > <DNS application service>), or the general alerts screens (Applications > ALERT MANAGEMENT > Active Alerts or Alert History).
