In addition to the site parameters, the site’s current status is displayed:
■
Agent Retries
—the number of Equalizer to agent probes that were resent.
■
Agent Misses
—the number of Equalizer to agent probes that received no response.
Missed probes can be due to interruptions in network connectivity between the
Equalizer server and site agents as well as site failures.
■
Triangulation Time-outs
—the number of agent to client triangulation probes that
timed out before a response was received.
■
Resource Errors—
the number of Equalizer to agent probes that returned a resource
unavailable error.
■
Site Returned—
the number of clients directed to this site.
■
Returned as Default
—the number of clients directed to the default site.
■
Average Ping Time—
—the average triangulation time for all clients successfully
contacted from this site. This represents all of the triangulation probes, whether or not
this site was selected to process the request.
■
Resource load
—the load on the above resource as calculated by the Equalizer agent.
The load incorporates data on resource response time, number of active requests, and
load-balancing variables.
Plotting Site Performance
If Envoy is installed, the Plot Site feature enables you to view a graphical representation of
the performance history for the selected site. To plot the performance history for a site:
1.
Log into the Equalizer Administration interface with view or edit access.
2.
In the left frame, click the name of the site whose history you want to view. The Site
Parameters are displayed in the right frame.
3.
Select Plot Site History from the local menu in the Site Parameters frame. The
graphical history for the selected site is displayed in the right frame.
By default, the Request Rate and Resource Down values for the previous half hour are
plotted. To change the information plotted, select the categories and duration you want to
plot and click the Plot button.
To zoom in on a portion of the graph, click the area that you are interested in.
Six values can be plotted for a site:
■
Probes Missed
—the number of requests where an agent failed to reply to Equalizer’s
probes.
■
Triangulation Errors
—the number of ICMP ECHO requests that the agent at this site
sent to clients and received no response.
■
Resource Down
—indicates that the resource in question failed to respond during the
period plotted.
■
Site Chosen
—the number of times that this site was returned in response to a client
query.
