To identify the critical factor that affects the network service, configure an SHM SLA to monitor the
following objects:
•
Devices—Router A, Router B, Switch C, Switch D, the mail server, and the DNS MX server.
•
Links—Link between routers, and links between Router B and switches in the branch.
•
Interfaces—Interface S2 on Router A and Interface S1 on Router B.

Requirement analysis
The main factors that can cause poor email services include the following items:
•
Performance of the links between Router A and Router B, Router B and Switch C, and Router B and
Switch D, such as jitter, one-way average delay, and unreachable rate.
•
Response time and device unreachable rate of Router A, Router B, Switch C, and Switch D.
•
Performance of the mail server and the DNS MX server, such as CPU usage, memory usage,
device unreachable rate, and the response time.
•
Performance of Interfaces S1 and S2, such as interface performance, maximum bandwidth usage,
inbound traffic, and outbound traffic.
To identify the critical factor that affects the network service, you can configure an SLA as described
in
that monitors and measures the KQI on the target objects.
