How to Diagnose Network Connection Issues
Diagnosing network connection issues
To help you diagnose network connection issues, you can view the status of and statistics about the iQuery® connections between BIG-IP® Global Traffic Manager™ (BIG-IP DNS) and other BIG-IP systems on your network. iQuery connection information displays for IP addresses that are configured on BIG-IP server objects.
Viewing iQuery statistics
On the Main tab, click
.The Global Traffic statistics screen opens.
From the Statistics Type list, select
Information about the iQuery connections between this system and other BIG-IP systems in your network displays.
When you want to estimate iQuery traffic throughput, click
The following statistics are reset to zero:
- iQuery Reconnects
- Bytes In
- Bytes Out
- Bytes Dropped
iQuery statistics descriptions
The information in the table describes the iQuery® statistics.
|IP Address||Displays the IP addresses of the servers that have an iQuery connection with this BIG-IP® DNS.|
|Server||Displays the name of the server with the specified IP address.|
|Data Center||Displays the data center to which the specified server belongs.|
|iQuery State||Displays the state of the iQuery connection between the specified server and the BIG-IP DNS. Possible states are:
|iQuery Reconnects||Displays the number of times the BIG-IP DNS re-established an iQuery connection with the specified server.|
|Bytes In||Displays the amount of data in bytes received by the BIG-IP DNS over the iQuery connection from the specified server.|
|Bytes Out||Displays the amount of data in bytes sent from the BIG-IP DNS over the iQuery connection to the specified server.|
|Backlogs||Displays the number of times the iQuery connection between the BIG-IP DNS and the specified server was blocked, because iQuery had to send out more messages than the connection could handle.|
|Bytes Dropped||Displays the amount of data in bytes that the iQuery connection dropped.|
|SSL Certificate Expiration||Displays the date the SSL certificate expires.|
|Configuration Time||Displays the date and time that the BIG-IP DNS configuration was last modified. The timestamps should be the same for all devices in a BIG-IP DNS synchronization group.|
