GroundWork Monitor Enterprise Edition | Version 8.7.0 | 2023/09/12

Minimum Docker version for GroundWork 8.5.2/8.7.0 is 20.10.13. If you installed Docker using recommended install steps, a system update should be all that is necessary to achieve this.

Known Issues and Limitations

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



Some of the included example dashboards which work for GroundWork 8.6 and below no longer work.

Updated dashboards will be provided on the Downloads page. New user-created dashboards work properly.

Nagios Contacts

The existence of Nagios contact templates which contain only the deprecated NoMa methods will put Nagios control dashboards into a state where commits are not possible.

Deleting any templates which cause this issue will restore ability to commit. References to these contact templates should optionally be changed.

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.

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.

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. 

Legacy NRPE check deprecated.This plugin should have already been replaced by check_nrpe plugin. Plugin check_nrpe_legacy is no longer included by default.Use of this plugin will require manually maintaining it in your nagios libexec directory.
