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 (GTM) 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 GTM configuration contains at least one BIG-IP server object with a self IP address.
To view information about the connections between BIG-IP GTM 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 iQuery. 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 GTM and the BIG-IP systems in your network, log in to that BIG-IP GTM 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-IPGTM.|
|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 GTM. Possible states are:
|iQuery Reconnects||Displays the number of times the GTM re-established an iQuery connection with the specified server.|
|Bytes In||Displays the amount of data in bytes received by the GTM over the iQuery connection from the specified server.|
|Bytes Out||Displays the amount of data in bytes sent from the GTM over the iQuery connection to the specified server.|
|Backlogs||Displays the number of times the iQuery connection between the GTM 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 GTM configuration was last modified. The timestamps should be the same for all devices in a GTM synchronization group.|
