JDisc Discovery 2.9 – Build 2923

Network Inventory and Documentation - ImprovementsAt JDisc, we do not like long update cycles. Customers need new features and bugfixes as soon as possible and not once or twice a year. That’s why we frequently release builds with new features and some bugfixes.

Build 2923 concentrates on improvements for the networking add-on and on some bugfixes for very large environments.

On Cisco devices, users can provide their own description for interfaces. This is very useful for documentation purposes and helps to identify the actual purpose for a particular interface. Up to now, this information was ignored by JDisc Discovery, but one of our customer pointed us to the relevant MIB. So it was pretty easy for us to collect this additional information and store it as annotation within our database. The report below illustrates the new field “Annotation”.


On Cisco devices, there are many ways to collect VLAN information. Several MIBs contain VLAN information. However we experienced, that not all MIB tables do always contain the desired information. Therefore, we had to change the SNMP MIBs used to collect the VLAN information and we switched to a new SNMP MIB table. The information in this table seems to be more reliable. Working on VLANs, we added a new report in the “networking” section within the device details dialog. Check out the screenshot below:


Furthermore, we have fixed some bugs:

  • The remote login agent could crash in rare cases when a firewall or intrusion detection system interferes interrupts the connection between discovery server and our remote login agent.
  • In large environments, we had problems storing the users discovered on domain controllers. With thousands of users, the SQL query that we created got too large and the database server refused to execute this query. We splitted the query into multiple smaller queries.
  • Saving a map (either a dependency or topology map) triggered a new layout for the graph. This was annoying, especially, when a user created his own layout by rearranging some nodes manually.

Stay tuned, there are many exciting features in the pipeline…
