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
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 theStatistics Typelist, selectiQuery.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, clickReset.The following statistics are reset to zero:
- iQuery Reconnects
- Bytes In
- Bytes Out
- Backlogs
- 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.
iQuery Statistics |
Description |
---|---|
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. |
