| IO_requests
|
The total number of packets received and sent per second |
Pkts/Sec
|
|
| IO_delay
|
The percentage of times network I/O was delayed |
Percent
|
A non-zero value over a period of time indicates a problem.
|
| Data_recvd_rate
|
Reports the rate
at which the network bytes are being received. |
KBytes/Sec
|
This measure indicates the amount of data coming to the database
server through the network. A high value of this measure indicates
higher rate of incoming data to the server. If this measure is
considerably high, the value of the default network packet size
parameter should be increased.
|
| Data_sent_rate
|
Reports the rate
at which the network bytes are being sent. |
KBytes/Sec
|
This measure indicates the amount of data going out of the database
server through the network. A high value of this measure indicates
higher rate of outgoing data from the server. If this measure is
considerably high, the value of the default network packet size
parameter should be increased.
|
| Avg_packet_size
|
The average number of bytes sent per packet |
Bytes
|
If the Adaptive server receives a command that is larger than the packet size, the server waits to begin processing until it receives the full command. Therefore, commands that require more than one packet are slower to execute and take up more I/O resources.
If the average bytes per packet is near the default packet size configured for your server, you may want to configure larger packet sizes for some connections. You can configure the network packet size for all connections or allow certain connections to log in using larger packet sizes.
