This is a continously updated list of known issues for released versions of Performance Guard. The list contains all issues that we think are of special interest to our customers and partners.

Version 5.4.x

Agent

PG-4554 Agent is using excessive resources on Citrix servers  

Agent uses 50-120 Mb of memory on Citrix servers depending on the load of the server. 

PG-xxxx OEM agents and network drivers

When installing the agent, any OEM agents older than version 5 installed on the same client may stop collecting network data because they are using a different network packet driver. The OEM agents must also be upgraded to current version.

PG-4300 SQL server traffic generates false response times in agent

TCP Keep-alive traffic may cause the agent to measure very high false response times.

PG-xxxx Uninstalling an agent may in some cases leave the agent in 'disabled' state

Problem: Uninstalling an agent may in some rare cases leave the agent in 'disabled' state. If you reinstall the agent without rebooting, the agent service is not created correctly.

Solution:

To prevent this problem: Before uninstalling, stop the agent service using the command  net stop "premitech pga" If you do this in a script, consider adding a 60 second delay before continuing. 
To fix this problem after it appears: Reboot the computer, uninstall the agent, and then reinstall the agent.

Server

PG-4466 Partial serverinstallation cannot be changed without complete uninstall

Problem: If you after installing Performance Guard services the first time later wants to uninstall one of the services or install one more service, you are not allowed to.

PG-4295 510to520post.sql is not executed when upgrading

Problem: When upgrading from PG version 5.1 to 5.2 the SQL server upgrade script 510to520.cmd executes the file "..\510to520post.sql" instead of correctly "510to520post.sql"

Version 5.1.44

Agent

PG-4165 Agent icon process consuming 100% of one CPU after install (since 5.1.36)

See description below: #PG-4165 Agent icon process consuming 100% of one CPU after install

PG-4203 Agent Icon consumes 100% CPU on Microsoft Terminal Servers (since 5.1.36)

See description below: #PG-4203 Agent Icon consumes 100% CPU on Microsoft Terminal Servers

Server

PG-4158 Server/Port graph heading is empty when selection agent super group

Problem: When selecting an agent super group in the Server/Port graph the graph heading does not contain the agent super group name but is empty.

Solution: There's no work around. Wait for a later version of Performance Guard.

PG-4157 Server/Agent graph does not work when agent super groups are selected

Problem: When selecting agent super groups in the Server/Agent graph the graph will most likely be empty.

Solution: There's no work around. Wait for a later version of Performance Guard.

PG-4054 Execution of DeleteDeadAgents may lock up the PG database on Citrix installations (since 5.1.36)

See description below: #PG-4054 Execution of DeleteDeadAgents may lock up the PG database on Citrix installations

Version 5.1.36

Agent

PG-4089 Agent icon cannot be removed

Problem: The agent icon does not disappear even you disable the "Enable Task Bar Icon" setting in the agent configuration.

Solution: A workaround to the problem could be to execute the following command after the installation of the agent:c:\Program Files\Premitech\PErformance Guard Agent\guardagent.exe -ug
The above command removes the following entry in the registry which prevents the agent icon from starting up when the users logs in.HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
"GuardAgentGui"="\"C:
Program Files\\Premitech
Performance Guard Agent\\GUARDagent.exe\" -gui"

PG-4165 Agent icon process consuming 100% of one CPU after install

Problem: In certain situations the agent icon process uses 100% of the CPU resources (or 50% on dual core systems) just after being installed. Apparently this may happen if a user logs in to the machine right after the agent is installed by a software distribution tool or by using Group Policy Objects in Active Directory. The problem can be identified by the fact that 3 guardagent processes will be present in the task manager process list and one of them will be using excessive CPU. Rebooting the machine causes the problem to disappear. This is a serious issue to address when installing the agent on production servers.

Solution: Schedule a reboot just after the agent installation.

PG-4203 Agent Icon consumes 100% CPU on Microsoft Terminal Servers

Problem: The agent icon uses all available CPU resources for each terminal services session.

Solution: On Microsoft Terminal Servers you need to remove the agent icon completely by executing the following command after the installation:c:\Program Files\Premitech\PErformance Guard Agent\guardagent.exe -ug
The above command removes the following entry in the registry which prevents the agent icon from starting up when the users logs in.HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
"GuardAgentGui"="\"C:
Program Files\\Premitech
Performance Guard Agent\\GUARDagent.exe\" -gui"

PG-4129 Agent uninstall does not remove PGExtHelper.dll

Problem: When uninstalling the agent, the file c:\windows\system32\PGExtHelper.dll is left behind on the system.
Solution: Don't do anything. The file does not harm your system and if you later install another version of the Performance Guard agent it will be overwritten with the correct version of the file..

Server

PG-4003 Upgrade of BTM v1. data is not correct

Problem: When upgrading from previous versions of Performance Guard and you are using the Business Transaction Monitor module, the data is not upgraded correctly.

Solution: Do not upgrade to this version. If you already have upgraded then please contact a Premitech consultant.

PG-4035 Citrix trend graph - Can not select empty ICA client group

Problem: In the Citrix trend graph it is not possible to select ICA Client Groups that have no agents installed.

Solution: Upgrade to a later version or disable the setting "Hide empty groups" in the menu Administration -> PGUARD Configuration on the Display tab.

PG-4054 Execution of DeleteDeadAgents may lock up the PG database on Citrix installations

Problem: If you have Performance Guard agents installed on Citrix servers and one of these agents is an old entry and is scheduled to be removed by the "DeleteDeadAgents" stored procedure, then the execution of the "DeleteDeadAgents" stored procedure may lock up the Performance Guard database.

Solution: Disable the stored procedure by replacing it with an empty procedure that does nothing or put a "RETURN" statement at the top of the stored database procedure "DeleteDeadAgents".

PG-4117 Collector refresh command throws runtime exception

Problem: Issuing the "refresh" command in the collector telnet interface causes the collector to throw a runtime exception and does not do a refresh.

Image Removed

Solution: If you need to refresh the collector please restart the collector service.

PG-4166 HelpDesk Wizard step 3 does not show a graph when no compare group is selected.

Problem: In step 3 of the Help Desk Wizard you will not see a response time graph unless you select an agent group to compare with.
