Version 8.1.1

GroundWork Monitor Enterprise | Version 8.1.1 | Release  
Update: Minor release version 8.1.1-1, see details below.

These release notes describe the new features and improvements, known issues and limitations for GroundWork Monitor 8.1.1. They also provide announcements as of version 8.1.1, including currently supported and end-of-life versions of GroundWork Monitor. 

This is an interim release, and while you may see various usability improvements, there are just a few new features to announce. We did correct several issues users have pointed out, or that we found in our testing. Thanks to all those who contributed suggestions and reported issues, we love to hear from you anytime at Please read the Fixed Issues section below to see what has been addressed in this release. We recommend all users look through this section when upgrading.   

New Features

GroundWork Monitor 8.1.1 does't have many new major features beyond those announced for 8.1.0, which were significant (Parent Child, dual certs, etc.). Attentive users will notice the first redesign of the Home Page, and will see some new options, and a smoother workflow around some of the screens.

  • Events in Status Summary: There's a new Events tab on the host and service info panel that will show you the last few events recorded for the host and service you are focused on. 

Fixed Issues

This section describes the fixes we have included in the 8.1.1-GA release. A few more issues were fixed in the minor update 8.1.1-1 as noted. 



Added Grafana Auth and monitor context to SLA dashboard iframe

You can now place Grafana dashboards in an iframe on the SLA dashboard


Cloud Hub Connectors need About screens

Added info and versioning to Cloud Hub connectors.


Make links in Event message text clickable

Useful for messages that contain hyperlinks to other systems


Added "Ack Now" button for hosts in Status view

A new handy button for acknowledging hosts with issues


Wrap long status text

Fixed an issue where really long status text was getting truncated in the Status Summary. We also added a "read more" link to expand it. 


Custom Reports for Events over time were not accurate 

Fixed an issue with the SQL queries and report content


cadvisor fails on SLES 15

The dependency in SLES 15 has been worked around. SLES 15 Works without error in GroundWork Monitor 8.1.1 


Update the Navbar and logo

The Navbar has a new look, with a new logo and a clock


Enable edit features in for admin user

The admin user can now access all custom reports features by default


The report_db data not adequate to generate accurate reports

We have a database in GroundWork called report_db which is used for getting availability reports. In some cases, this data was not adequate to the job, so we enhanced it. 


Synchronizer failure on very large datasets

The synchronizer could sometimes fail to add hosts if the dataset was too large, fiixed


Comments sent with acks to Nagios don't propagate to Foundation

Fixed an issue where comments coming in to the Nagios channel weren't getting updated in Status Summary


Elastic connector metrics auto-suggest

Fixed for easier configuration


License screen updated

We show the licensed version now, and better error messages


Speed up synchronizer

Some imports of large initial configurations could take a while to synchronize, it's much faster now


Changing master cypher breaks Nagios main connector

You can now change the master cypher without any internal apps being affected


Elastic Connector runs out of memory

Fixed a memory allocation problem


Service Names added to Event view search

You can now filter events on service names as well as message text, etc. 


Versioning added to TCG connectors

We now show the version and build dates in the Status tab for all TCG connectors


Unable to add service with dependents after removal from host

Nagios dependencies couldn't be added again after being removed


Docker hosts not removed when deleted

In some cases, notably upgrades from 8.0.1, Docker connector hosts would remain after the connector was deleted, these are now removed correctly


Connection error when connecting to child server

A spurious error was being thrown when connecting to a child server from a parent


Elastic connector query on alternative index pattern gets no matches

We expended the range of the Elastic connector to match against multiple index patterns


LDAP user could not set downtime

Some LDAP users would get an error message when setting host or service downtimes, this is now fixed


Enhanced the LDAP UI and fixed UI issues

The LDAP UI is now clearer, and a couple of minor issues were fixed


Fixed issue where the wrong NOCBoard Dashboard would be displayed 

The refresh of the prior dashboard could overwrite the current one. (Fixed in 8.1.1-1)


Update max size of requests to groundwork to 25mb

Really big configurations sometimes overloaded nginx. (Fixed in 8.1.1-1)


Adjusted Synchronizer error handling, serialization

Really big configurations could overload the Synchronizer, making it slow. (Fixed in 8.1.1-1)


Alpine container downloaded during install

The installer had a bug that made Internet connectivity a requirement. It no longer is. (Fixed in 8.1.1-1)


Installer was missing unattended option

Now you can run the installer with the option --unattended to get a default standalone install (Fixed in 8.1.1-1)


Downtime scheduler option re-enabled

In 8.1.1-GA, the option to schedule downtime for services with a regex was disabled. (Re-enabled in 8.1.1-1)

Known Issues

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


Monitoring Plugins

Some plugins may not work. The plugins included with GroundWork Monitor 8.1.1 are incompletely tested

If you encounter a plugin you need to work that doesn't, please file a support case. We will get you a working version as soon as possible, and include it in later releases.


Cannot delete user 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. 

Business Service Monitoring

Default bsm-service-01 configured but empty. The service bsm-service-01 on host bsm-host is included as an example of Business Service Monitoring. It is in the unknown state as the member list is empty.

You can remove this (or add members) by going to the Configuration > BSM and SLAs > BSM > Manage Groups, and clicking the delete icon next to the group. 


Notify Contacts check box does not work. There is a Notify Contacts checkbox on the Acknowledgment modal dialog that does not work.

Do not use this checkbox, It will be removed in a future version. 


Monitored and Graph check boxes do not stop monitoring or graphing. The new Elastic connector has a metrics selection that allows you to define and then disable a given metrics monitoring and graphing function. Unchecking these options (disabling the monitoring and graphing) has no effect.

For now, do not define metrics that you do not wish to see in the Status Summary. 

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.

Docker Connector

Docker connector does not detect service unknown on down containers. Theres a bit of a strange look when a container goes down, since the services for memory and CPU etc. remain in an OK state.

Use a ping to the container address to make sure you know  and get notified when a container dies. 


Current supported versions of GroundWork Monitor Enterprise include the latest versions 8.1.1, 8.1.0, 8.0.1, 8.0.0, and version 7.2.1. Support for version 7.2.1 will expire December 31, 2021.
