We've recently made several changes to X-Link to improve message delivery times and reduce CPU usage. Some changes are to all editions while some are only to the Enterprise Edition. To help customers understand more about X-Link, we've added a set of performance visualizations to all editions to provide insight into X-Link operations. The intent is to show when additional hardware and/or an upgrade to the Service or Enterprise Edition could improve Message Delivery Times and/or CPU Usage.
The CPU Usage Visualization Advanced Help
To access the CPU Usage Visualization, just press the CPU Utilization button in the Visualizations box on the lower left of the X-Link Dashboard as shown below:
A detail box will display and may say Please wait while graph is rendering. A graph, like the one below, should then appear.
Pointing the cursor at the data in the graph will provide a pop up tip showing the underlying data represented in the graph.
At this point, you can choose another date and/or choose a specific hour of a particular day. We choose the 10 am hour as it looks like there was a lot of activity that subsided at around 10:50 am. It is important to note that this graph represents all computer processing by all programs, Windows, and other users. In this particular case, an anti-virus full scan was started at 1:00 am and ended at approximately 10:50 am.
Looking at the next day, it appears X-Link and/or the computer was turned off for about 6 hours.
In the above graph it seems odd that the CPU Usage dropped at 10 pm. I don't know what happened at that time, so knowing why it happened is impossible to say. This is a case where keeping a log of problems, issues, and concerns would help to relate the graphs to the issues.
There are no differences in this graph when running the X-Link Enterprise Edition.
So what does this graph mean?
The sample graphs above came from my development system, but I have a pretty regular usage pattern, so my graphs may not look that different from yours.
This graph is focused on your entire computer, not just X-Link. One good indicator of the amount of usage a computer has is the CPU usage. Generally, if the usage stays below 75 to 80%, then you still have CPU resources left for peak moments. We use the 75 to 80% rule of thumb as we are averaging the CPU usage over one minute periods. Again, this value is a rule of thumb and depends on many factors of what software is running, etc. Generally we see if the CPU usage approaches 100%, that the delivery times of messages increases as well.
Hopefully information like a date the symptom started can be helpful to averting the issue. But just knowing that doesn't mean it is X-Link. For example, a new program may have been installed that uses a significant amount of resources, slowing the entire computer down.
Thank you. We hope this entry has helped you with the use of the Daily Message Counts Visualization.
