Statistics
The Monitor-Statistics pageimg
allows you to view information about the traffic flowing through your
jetNEXUS ALB-X. The page is split into four sections
and organised below.
Total Input/Output
This statistic reports the raw data in and out of the ALB-X. The unit
of measurement will change as the size grows from kbps to Mbps to Gbps
Compression
Content Compression to Date
This statistic reports how much compression the jetNEXUS ALB-X has achieved on compressible content. A typical percentage for this lies between 60-80%.
Overall Compression to Date
This statistic reports how much compression the jetNEXUS ALB-X has achieved on all
content. A typical percentage for this depends how many pre-compressed
images are contained on your services. The more images the smaller the
overall compression percentage is likely to be.
Hits and Connections
This section contains the overall statistics for hits and transactions.
Overall Hits Counted
This
is the cumulative number of non-cached hits since last reset. On
the right hand side the figure will show the current number of hits per
second.
Total Connections
This
is the cumulative number
of TCP connections since last reset. The first figure on the right hand
side you can see the number of TCP connections per second to the ALB-X.
The second number is the number of TCP connections per second
to the content servers.
Example 6/8 connections/sec – This means we
have 6 TCP connections per second to the Virtual Service and 6 TCP
connections per second to the real servers.
Peak Connections
This
is the maximum number of TCP connections to the jetNEXUS ALB-X.
The number on the right hand side gives the current number of active
TCP connections.
Caching
This section will show the
overall statistics in relation to caching when it has been applied to a
channel. If caching has not been applied to a channel and configured
correctly you will see 0 cache contents.
From Cache
Hits:
transactions served from the jetNEXUS ALB-X cache since last reset. A
percentage of total transactions is also provided.
in Kilobytes served from the jetNEXUS ALB-X cache. A percentage
of total data is also provided.
From Server
the content servers since last reset. A percentage of total
transactions is also provided.
Bytes:
from the content servers. A percentage of total data is also
provided.
Cache Contents
Hits:
Bytes:
of the jetNEXUS ALB-X cached objects. A percentage of the maximum cache
size is also provided.
Hardware
This section provides the overall usage stats for the jetNEXUS ALB-X.
Disk Usage
This number gives the percentage of disk space currently used and includes such things as the log files and the
cache which is periodically stored on the hard drive.
Memory Usage
This number gives the percentage of memory currently used. The larger number in brackets is the total amount of memory allocated to the ALB-X. It is recommended that this is a minimum of 2GB.
CPU Usage
This number gives the percentage of CPU currently used by jetNEXUS ALB-X. It is natural for this to fluctuate.
