Overview

User logs in to the Real Time Monitor from Monitor >Real Time but sees no flows.

This article provides troubleshooting steps to help fix this issue.

Resolution

Perform the following troubleshooting instructions:

1. Check if no actual traffic flowing through the Exinda, to verify:

   • Navigate to Monitor >Interfaces and look for actual traffic flowing currently by changing the time range to Last 5 minutes.

     • Note: A graph shows up with all the bandwidth being used from a physical point of view right at the interface, regardless of software specific problems.

2. Check for the two IPs involved in any given flow, and if they happen to belong to configured Network Objects that are set as Internal, the traffic will not be monitored:

1. Navigate to Configuration > System > Setup > Monitoring.

2. Uncheck Ignore Internal-Internal checkbox.

3. Click  Apply Changes button right below this options box.

   • Note: This step will just rule out the Network Objects set as Internal as a problem. If after applying the changes the flows are not coming back, please re-enable this option.

3. Restart the Collectord process:

4. Reboot the unit completely to ensure that all processes restart so that the graphs come back.

5. Check the configuration file for any bridges and interfaces that do not exist in the hardware. (In latest versions, Exinda gets into reporting issues in this scenario)

   1. Go to Configuration > System >NICs and see how many bridges and interfaces you have (including its names).

   2. Navigate to Configuration > System > Maintenance >Load Running Config.

   3. Write down the name of the non-existing bridges and its interfaces in the "Bridging configuration" and/or "Network Interface Configuration" sections, where any of the commands are referencing them. For example, bridge br10 involves interfaces eth10 and eth11.

   4. Remove non-existing bridges and interfaces from the configuration by executing the below mentioned commands from the CLI (Command Line Interface). Consider a scenario where XX is the bridge number, YY is the LAN interface number and ZZ is the WAN interface number:
      

      1. exinda> en

      2. exinda# conf t

      3. exinda(config)# no bridge brXX

      4. exinda(config)# no interface ethYY create

      5. exinda(config)# no interface ethZZ create

      6. exinda(config)# no interface brXX create

   5. Re-load the running config to ensure those command lines are no longer there.

   6. You might be prompted to Restart the Optimizer, restart the Optimizer, and Save the changes.

The above steps should resolve this issue.

Additional Information

To avoid applying non-existing interfaces and bridges commands to configuration files:

Please avoid migrating configuration files from one exinda to the other using the configuration file in binary format (which is the one you download by clicking on the name of the Active Config under System > Maintenance). Instead, please download the text version (click on the floppy disk icon next to the active running config) and then copy and paste pieces of the configuration file onto System > Maintenance > Import Config. While doing this, simply copy and paste lines that are part of the configuration of Network Objects, Schedule Objects, Applications, App-groups, policies and circuits (among others) and avoid pasting referrals to hardware (for example the "Bridging configuration" and/or "Network Interface Configuration" sections)
