OverviewUser logs in Monitor-->Real Time and sees no flows.
1.- There might be actually no traffic flowing through the exinda, to ensure there is, simply go to Monitor-->Interfaces and look for actual traffic flowing currently by changing the time range to "Last 5 minutes" (this is the graph that shows all the bandwidth being used from a physical point of view right at the interface, regardless of software specific problems).
2.- Go to Configuration-->System-->Setup-->Monitoring and disable "Ignore Internal-Internal" checkbox, then click on the "Apply Changes" buttom right below this options box. This option, enabled by default, checks 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. This step will just rule out that as a problem. If after applying the changes the flows are not coming back, please re-enable this option.
3.- There is a process called Collectord that might need a restart. We recommend rebooting the unit completely to ensure that by restarting all processes so the graphs come back.
4.- Finally, in latest versions, Exinda gets into reporting issues when the configuration file involves bridges and interfaces that do not exist in the hardware. Please go to Configuration-->System-->NICs and see how many bridges and interfaces you have (including its names).
Then go to Configuration-->System-->Maintenance-->Load Running Config. In the "Bridging configuration" and/or "Network Interface Configuration" sections, look for any command referencing to an interface or bridge that actually does not exist (later in this article we will give you a few tips on how to avoid this from happening again). If there are, write down the name of the non-existing bridge and its interfaces. For example, bridge br10 involves interfaces eth10 and eth11.
To remove these from the configuration (XX is the bridge number, YY is the LAN interface number and ZZ is the WAN interface number):
exinda# conf t
exinda(config)# no bridge brXX
exinda(config)# no interface ethYY create
exinda(config)# no interface ethZZ create
exinda(config)# no interface brXX create
Then re-load the running config to ensure those command lines are no longer there. The system might ask you to Restart the Optimizer (which is actually a good sign). Restart the Optimizer and Save the changes. The issue should be solved.
Additional InformationTo 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)
