The amount of memory required by the sFlowTrend-Pro service varies considerably, depending on how many sFlow agents are monitored, and the quantity and type of network traffic. The default memory available to the service is generous and suitable for most installations. However, if memory runs low then events will appear in the event log warning of this, and performance of sFlowTrend-Pro may become poor.
To increase the memory available to the service, first go to
the bin directory, in the directory on the
server where
sFlowTrend-Pro was installed. Here there should be a file named
sflowtrend-server.vmoptions. Edit this file
with a text editor, and add a line to the end with this format:
-Xmx1800m
This will change the memory available to be 1800 MB. The memory can also be reduced in a similar way. After making this change, the sFlowTrend-Pro service must be restarted for the change to take effect.

It is very important to specify a valid memory configuration. If the directive is typed incorrectly, or has an invalid size of memory, then the sFlowTrend-Pro service will not start. Be aware that with a 32-bit JRE, the maximum memory that can be specified is approximately 1800 MB; if the size is greater than this, then the service will not start. If you are using a 64-bit OS and a 64-bit JRE, then a larger amount can be specified. |
