Configuring HP WebQoS
Modifying Configuration Files Before Start-Up
then the default value is 2048.
The maximum number of connections that are polled or checked for data. This parameter prevents connections with no data from using too many file descriptors. HP recommends that this value be a percentage of the maxfiles kernel parameter.
•NoDataConnectionTimeout - Default: 30 seconds
The amount of time, in seconds, to wait before closing a connection without data.
If no data is received for a connection in this amount of time, the connection is closed.
•PollThreadSleepTime - Default: 100 milliseconds
The amount of time, in milliseconds, to wait before checking if any data has arrived.
If a connection with no data is received, then wait for this amount of time before checking the connection for the arrival of data.
The total number of times the connection is checked for data during the NoDataConnectionTimeout time is calculated by dividing NoDataConnectionTimeout by this value. For example, using the default values, the connection with no data is checked for data 300 times (30 seconds/100 milliseconds) in a 30 second period.
•WaterMarkForNoDataConn - Default: 95% of MaxPollDescriptors
When MaxPollDescriptors is reached, an event is sent indicating that there are too many connections with no data. When the total number of file descriptors falls below this percentage of MaxPollDescriptors, another event is sent indicating that the number of connections with no data is at an acceptable level.
Logging and Tracing Parameters
The following parameters affect the amount of information written to the logging and tracing files.
•LOGLEVEL - Default: 3 (informative logging)
The amount of logging information that is written to the files
/var/opt/webqos/logs/qoslog and /var/opt/webqos/logs/acclog. Logging values are:
0 - None
