Known Issues and Limitations

This section lists any known issues and limitations with work-arounds.


Nagios Monitoring

Renaming a host to the same name except for case will require 2 commits. The renaming of a host to the same name with differences only in the case of the characters is possible, but requires committing the configuration twice.

Run the Commit (or, for Parent Managed Child, the Build Instance) process a second time, and the renamed host will appear. 

Nagios Monitoring

Adding two hosts with the same name except for case will not work. If you ever find you need to have two hosts with the same name except for case in the Nagios system, this is allowed. It will not show both hosts, however, only the first one you add, and it won't work at all if you do it in a single commit.

To do this (admittedly really rare thing), fist add one of the hosts. Choose the one with the name you want to see, add it and commit. Then add the second and commit. The second host's services will be merged into the first. 


Cannot delete users created by LDAP sync. If you sync LDAP to GroundWork, the users who log in are imported. There's not much point in deleting them unless you disconnect the LDAP server, but even if you do so, the delete function isn't working.

There is a work-around, but then again there's no harm in leaving these user accounts alone. They will fail login once the LDAP server is inactive. If you really must delete them, please contact support. 

Nagios Container

It's possible to overload the Nagios instance in GroundWork. Nagios uses workers that communicate with the services it runs. In some cases the default provisioning isn't enough to keep up with a really active alert stream.

You can override the default provisioning of workers in Nagios with the check_workers directive. See How to configure check_workers.

Custom Reports

Optional Jasper Server slow to start. If one starts the optional Jasper Server, it may take several minutes to become available.

Wait several minutes after starting the system with the Jasper Server loaded before accessing the Custom Reports menu item. 

TCG-SNMP restart generates unknown status

When restarting the (new) TCG-SNMP connector, the initial poll may generate UNKNOWN status for the network interfaces. 

We recommend adjusting the notification rules for this to avoid alarm fatigue. 

Cron-Controlled GroundWork containers generate SUSPENDED alerts

Jobs scheduled VIA the cron container generate SUSPENDED alerts. This is correct behavior, but may cause unwanted alarms.

We recommend adjusting the notification rules for this to avoid alarm fatigue. A separate rule for the DOCK-H:cadvisor group with a 1-minute delay can suppress these alarms.

Unattended mode install is not enabled

The installer won't support the --unattended  mode option to install standalone with default settings in this version. 

This convenience feature will be enabled again in future versions.  

Archive Migration initially incomplete

Upgrades to the system will migrate the foundation database but will not completely migrate the archive database until the first archive run (overnight in the cron timezone)

This may affect any queries you want to run against the archive database, especially those for host address values, but only for the day of upgrade. 


Important announcements as of 8.2.2.

Supported Versions

Current supported versions of GroundWork Monitor Enterprise include the latest versions 8.2.2, 8.2.1, 8.2.0, 8.1.3, and version 7.2.1. Support for version 7.2.1 will expire December 31, 2022 (see GroundWork Monitor Enterprise Sunset note below). Support for 8.0.x is now expired.

GroundWork Monitor Enterprise 7.x Sunsetting

Support for version 7.2.1 will expire December 31, 2022.

We have extended support for 7.2.x for another year, to give some of the more complex customers in our installed base more time to transition. GroundWork 7.x will be retired from active support at the end of this year. Customers with support contracts for GroundWork Monitor 7.x will continue to receive support from GroundWork Support for this version until December 31, 2022, and for 8.x thereafter. It's our goal at GroundWork Open Source to make the transition from GroundWork Monitor Enterprise 7.x to GroundWork Monitor Enterprise 8 as seamless as possible for our Customers and Partners. Please contact GroundWork Support and let us help you plan and make this transition.
