QoS Monitoring

[pmoorey]

Hi,

Please could someone advise the best method of monitoring QoS policy maps using SNMP.

I use a combination of Castle Rock SNMPc and SolarWinds Orion.

Please could someone tell me the appropriate SNMP Object IDs to graph the data.

Kind regards,

This link is a little old but should be of some help. Also caontains links to configuration tasks as well.

here is some documentation I put together to monitor QoS with MRTG...minus the screen shots:
Setup MRTG to monitor QoS Policies
1. Install MRTG on system
a. Follow instructions

http://www.mrtg.org

2. Do a snmpwalk of ifDescr to get all interfaces
a. Make note of the number following ifDescr.xx for the interface that is desired to be monitored
3. Do a snmpwalk of cbQoSIfIndex (oid = 1.3.6.1.4.1.9.9.166.1.1.1.1.4) to get the list of ‘logical’ interface for which a policy map is assigned.
a. Example: Serial interface 5/2:0 in Image1 is mapped to 1549 in Image2
i. From Image1:
1. IF-MIB::ifDescr.16 = Serial5/2:0
ii. From Image2:
1. SNMPv2-SMI::enterprises.9.9.166.1.1.1.1.4.1549 = 16
4. Do a snmpwalk of cbQoSCMCfgEntry (oid = 1.3.6.1.4.1.9.9.166.1.7.1.1) to get the arbitrary numbers that are assigned to the configured class-maps on the router.

5. Do a snmpwalk of cbQosConfigIndex (oid=1.3.6.1.4.1.9.9.166.1.5.1.1.2). This will return the arbitrary number combination of the interface ID and the Class map. **Generates a long list, so recommend sending to a text file, which would also allow for search features.
a. Continuing example above, to find the OID to watch with MRTG, to monitor the CM-Scavenger class map on Serial 5/2:0, would want to scroll in the text file to the lines starting with: .1.3.6.1.4.1.9.9.166.1.5.1.1.2.1549.xxxx = yyyy
b. Then look for a yyyy value of 1091
i. From above example:
.1.3.6.1.4.1.9.9.166.1.5.1.1.2.1549.1613 = 1091
ii. The OID is that would be added into the MRTG Configuration file.
.1.3.6.1.4.1.9.9.166.1.15.1.1.11.1549.1613
iii. The last 2 values in the oid are taken from the previous snmpwalk
6. Example of MRTG Configuration file for example above:

EnableIPv6: no
WorkDir: /var/
