3.4 Test setup and results of the Alert and Task Management feature in
OpenManage Enterprise 3.4
3.4.1 Recommendations for setting an environment to test Alert and Task
Management feature in OpenManage Enterprise 3.4
• Reception of alerts is supported with 5,000 alerts per minute for 60 minutes without any drop with no
alert actions configured. This implies appliance will receive 85 alerts per second continuously for 1hr
without any alert drop.
• With 1 alert action (email/Trap forwarding) configured and mapped with 8,000 discovered devices,
reception of alerts is supported up to 85 alerts per second for a duration of 60 minutes with a
possibility of 20% alert drop. Restarting services will help receive more number of alerts if such a
situation happens.
• With all the alerts actions configured, reception of alerts is supported till 9 alerts per second with a
possibility of 25% alert drop, if continued for long duration. Restarting services will help receive more
number of alerts if such a situation happens.
• Key factors determining alert reception in case of alert actions configured:
- No. of devices selected.
- Time interval between alert reception.
- Number of Alert actions configured
3.4.2 Test environment and results of the Alert and Task Management feature in
OpenManage Enterprise 3.4
Environment used:
• CPU and memory data for alerts with a single alert action configured (such a Email) was captured for
a reception of 50,000 alerts, at 85 alerts per second, for 5 cycles, with an interval of 2 hours between
each cycle.
• The alert burst data was captured by generating 50,000 alerts together in the network and received
by OpenManage Enterprise. Alert actions were not configured.

• In case of an alert burst when all the alert actions are configured (For example Alert forwarding,
Syslog, Email, Remote script, and so on), the alerts will drop at a much higher rate. During our testing
