GroundWork Monitor Enterprise 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 support@gwos.com. 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.

Known issues

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

CategoryTitleDescriptionWork-around
Monitoring PluginsSome plugins may not workThe plugins included with GroundWork Monitor 8.1.1 are incompletely testedIf 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.
LDAPCannot delete user created by LDAP syncIf 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 MonitoringDefault bsm-service-01 configured but emptyThe 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. 
Acknowledgements Notify Contacts check box does not workThere is a Notify Contacts checkbox on the Acknowledgment modal dialog that does not workDo not use this checkbox, It will be removed in a future version. 
Connectors/TCGMonitored and Graph check boxes do not stop monitoring or graphingThe 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 ContainerIt's possible to overload the Nagios instance in GroundWorkNagios 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 ConnectorDocker connector does not detect service unknown on down containersTheres 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.
