How does Zenoss monitor devices with dozens (or even hundreds) of interfaces,
and how is this information represented on a graph?
Is it one "service check" per interface? ie: does it have to connect to the
device once each time per interface?
Is it one SNMP query per interface, or can this be consolidated into one
connection/query for all interfaces?
How is this displayed in graphs? is it one graph per interface, is it one
massive graph with hundreds of little lines?
Is there the ability to have a 10,000 ft view of the whole device - which is
what we network admistrators (and others prefer) ?
Several examples of devices to monitor are like the Cisco AS5300, AS5400, and
AS5800.
The AS5800 can have close to 800 connections, which all need to be monitored.
Dan,
Zenoss builds a list of all OIDs it is interested per device and
collects them in one pass. So the performance of collecting a large
number of interfaces is quite good. The graphs are one (or more)
graphs per interface. A typical Ethernet interface will graph bps,
packets and errors.
There is no default "10,000 ft. view" if I understand your term
correctly. You'd have to drill down into the interface you were
interested in. However, custom reports can be created to interpret the
collected data however you want.
