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
Ensure that the BIG-IP® DNS configuration contains at least one BIG-IP server object with a self IP address.
To view information about the connections between BIG-IP DNS and other BIG-IP systems, view 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
To view information about the iQuery® connections between a different BIG-IP DNS and the BIG-IP systems in your network, log in to that BIG-IP DNS and repeat this procedure.
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.|
