Quality of Service
The SNMP plugin discovers the Quality of Service (QoS) policies, classes, and match statements on any Cisco device on which you enable Class Based QoS. QoS polls all ClassMap, PolicyMap, and Match Statements to collect statistics that include summary counts/rates by traffic class before and after any configured QoS policies are enforced. Detailed feature specific statistics are available for select PolicyMap features.
QoS Objects
-
Match Statement: Displays the specific match criteria to identify packets for classification purposes.
-
ClassMap: Displays the traffic class you define that contains one or many match statements that enable you to classify packets into different categories.
-
PolicyMap: Displays the policy you define to associate each QoS action to a traffic class (ClassMap).
-
Service Policy: Service policy is a policymap that is attached to a logical interface. Because a policymap can also be a part of the hierarchical structure (inside a classmap), the SNMP plugin considers a policymap that is directly attached to a logical interface to be a service policy.
A logical interface in this context is one of the following: a main-interface, a sub-interface, a Frame Relay DLCI, an ATM virtual circuit, or the control-plane on the router.
The SNMP plugin only monitors service policies, since service policies influence the flow of traffic through interfaces on the router.
When the SNMP plugin discovers QoS on an interface, the names of the objects appear as follows:
"Interface""In/Out""Policy Name""Class""Type"
Et3/0 In - MyQoS - MyHttp Class
Each type of QoS has its own indicators and uses, but the main type is the class. Class objects can indicate how many bytes went into the class, how many bytes came out, how many bytes were dropped, and how many bytes were dropped due to RAM limits.
The Policy Browser enables you to define a policy that triggers an alert when the number of dropped bytes exceeds a certain number and the Report Manager enables you to define a report for the TopN reports that includes the most-dropping QoS policies.
