Monitoring
Cisco Secure Email Cloud Gateway
Cloud Email Security (CES) is monitored by the Cisco Operations team and provides proactive monitoring of alarms generated by CES instances.
Status of the CES environment can be seen here: https://status.ces.cisco.com
Status of Email Services (Signature Updates, etc): https://urgentnotices.statuspage.io/
How will I be notified of an issue?
When a customer is on-boarded the technical contact that is provided will be sent notifications of maintenance windows and issues.
❗ Monitoring and alerts do not apply to Beta Appliances in a customer Cloud Gateway instance as these are considered to be non-production allocations.
How do I add email addresses for notifications?
To have new or additional contacts added to the customer notification list, please reach out to Cisco TAC and request an addition to the CES notification list.
Responsibility Matrices
Infrastructure
| Description | Cisco | Customer |
|---|---|---|
| Monitor Datacenter connectivity and issue alerts of the potential impact | x | |
| Monitor ESA and SMA instances for availability | x | |
| Monitor supporting systems availability (billing, licensing, and provisioning systems) | x | |

What thresholds do the alarms get triggered on?
| Counter | Small | Medium | Large |
|---|---|---|---|
| Active Recipients | 3000 | 6000 | 10000 |
| Connections In | 300 | 300 | 300 |
| CPU utilization | 95% | 95% | 95% |
| Hard Bounced Recipients | 2000 | 3000 | 5000 |
| Kb Free | 1,000,000 | 1,000,000 | 1,000,000 |
| Msgs in Work Queue | 1200 | 2500 | 5000 |
| Oldest Message | 432000s | 432000s | 432000s |
| RAM Utilization | 60 | 60 | 60 |
| Soft Bounced Events | 2000 | 3000 | 5000 |
| Total Utilization | 90% | 90% | 90% |
All rates are shown as the average rate at an event that occurs per hour at the specific point in time the query is made. Rates are calculated for three intervals, the average rate per hour over the past one (1) minute, the past five (5) minutes, and the past fifteen (15) minutes.
For example, if the Cisco appliance receives 100 recipients in a single minute, then the rate for the one (1) minute interval will be 6,000 per hour. The rate for the 5-minute interval will be 1,200 per hour, and the 15-minute rate will be 400 per hour. The rates are calculated to indicate what the average rate for the hour would be if the rate for the one-minute period continued. Therefore, 100 messages each minute would yield a higher rate than 100 messages over 15 minutes.
