Using the Monitor - All EMS Servers
These displays
present performance metrics and alert status for all EMS servers.
The first three displays show different views of the same data:
-
All Servers
Heatmap: Heatmap shows server and
alert status for all EMS servers.
-
All Servers
Table: Table
shows all available utilization metrics for all EMS
servers.
-
All Servers
Grid: Grid
enables you to see general performance of EMS
servers
in parallel.
If you have few servers, this
display is useful for
verifying servers are active and generally performing as expected.
The last display provides a
high-level view of servers and their connections:
-
All Servers Topology:
Topographical map shows server routes, as well as the status of active
servers and standby servers that form a fault-tolerant pair.
All Servers
Heatmap
View status and alerts of all EMS servers.
Use the Metric drop-down menu to view to
Alert Severity,
Alert Count,
Connections,
Pending Messages, Incoming Message Rate, Outgoing Message Rate
or Message Memory Percent (%).
The heatmap is organized by host, each rectangle representing a server.
The rectangle
color indicates the most critical alert
state.
The rectangle size
is the same for each server.
Click on a node
to drill-down
to the Single Server
Summary display and view metrics for a particular server.
Toggle between the commonly
accessed Table, Grid and Heatmap displays. Mouse-over
rectangles to view more details about host performance and status.
NOTE: Click the
 button to view
the current display in a new window.
| Server Count |
The
total number of active, inactive and standby EMS servers. |
| Active |
The
total number of currently active EMS servers. |
|
Total Msgs In/s |
In/s: |
The total number
of incoming messages, per second, from all producers and consumers on all
EMS servers. |
|
Out/s: |
The total number
of outgoing messages, per second, from all producers and consumers on all
EMS servers. |
|
Pending |
The total number
of pending messages waiting to be processed on all EMS
servers. Click to open the All Servers Table
display. |
| |
|
Show |
Select
the type of servers to display data for. By
default, all active servers are displayed. |
| Inactive
Servers |
Select to include
servers that are not
currently
running.
Inactive Servers are represented in
dark red. |
| Standby Servers |
Select to include
servers that are currently in Standby mode. Standby Servers
are represented in blue. |
| Names |
Select to display
the names of servers on the hosts. |
| Log |
Select to
enable a logarithmic scale. Use Log Scale to see usage
correlations for data with a wide range of values. For example, if a
minority of your data is on a scale of tens, and a majority of your data is
on a scale of thousands, the minority of your data is typically not visible
in non-log scale graphs. Log Scale makes data on both scales visible
by applying logarithmic values rather than actual values to the data. |
|
Auto |
Select to scale the metric to the color gradient
bar. Deselect to use the default settings. For example, by default, the
Pending Messages color gradient bar maximum value is 300. When
Auto is selected,
the color gradient bar maximum value
adjusts to the current maximum value in the heatmap. The following are the
metric default settings:
- Alert Severity: 2
- Alert Count: 3
- Connections: 20
- Pend Msgs: 300
- In Msg Rate: 80
- Out Msg Rate: 80
- Msg Mem %: 80
|
|
Metric |
Select
the metric to display in the heatmap. Each Metric has a color gradient bar
that maps relative values to colors.
The heatmap organizes the servers by host,
each rectangle (node) representing a server.
The size of the rectangle
is the same for each server
(regardless of server metrics).
Mouse-over any node to display the current
values for the metric selected from the Metric drop-down menu.
Click on a node to drill-down to the
Single Server Summary
display and view metrics for a particular server.

| Topology |
Routes
are shown between the active server and the standby server which form a
fault-tolerant pair. Either of the servers in a fault-tolerant pair can
become the active server or the standby server. Show Standby Servers
and Show Inactive Servers enable you to include or exclude standby
and inactive servers. Inactive
Servers are represented in
dark red. Standby
Servers are represented in
blue. By default, standby servers are included in the
topology and inactive servers are not.
Typically, it takes about 30 seconds for a server to appear in the display
after startup.
The active server in a fault-tolerant pair appears in green with the suffix
(A) appended to its URL. The standby server appears in blue, with the
suffix (S) appended to its URL. Their link is blue and labeled FT.
If the active server fails:
- the failed server becomes inactive, its
suffix changes to (X!), and the node turns red with a red
outline.
- the standby server becomes active, its
suffix changes to (A!), and the node turns green with a red
outline.
- the link between the two servers turns
red.
If the standby server fails:
- the failed server becomes inactive, its
suffix changes to (X!), and the node turns red with a red
outline.
- the active servers' suffix changes to (A!)
and it is outlined in red.
- the link between the two servers turns
red.
If a failed server recovers:
- the recovered server becomes the standby
server, its suffix changes to (S), and the node turns blue with a
grey outline.
- the active servers' suffix (A!)
changes to (A), and the red node outline changes back to grey.
- the link between the two servers changes
back to blue.
