VMW Standard Virtual Switch Network Utilization

Purpose

This rule checks the levels of network utilization on VMware standard virtual switches.

Scope

VMWHostVirtualSwitch

 
Table 73. Rule Definition
Conditions
State
Action

The levels of network utilization on all monitored standard virtual switches is below the percentage set by the VMW:StandardVirtualSwitchNetwork.warning variable. The global default value of this variable is 75, meaning that in a default installation the network utilization of each of the monitored standard virtual switches is 75% or lower.

Normal

None

The level of network utilization of a standard virtual switch reached the percentage set by the VMW:StandardVirtualSwitchNetwork.warning variable. The global default value of this variable is 75, meaning that in a default installation a Warning alarm is generated if the network utilization of a standard virtual switch is higher than 75%.

Warning

None

The level of network utilization of a standard virtual switch reached the percentage set by the VMW:StandardVirtualSwitchNetwork.critical variable. The global default value of this variable is 85, meaning that in a default installation a Critical alarm is generated if the network utilization of a standard virtual switch is higher than 85%.

Critical

None

The level of network utilization of a standard virtual switch reached the percentage set by the VMW:StandardVirtualSwitchNetwork.fatal variable. The global default value of this variable is 95, meaning that in a default installation a Fatal alarm is generated if the network utilization of a standard virtual switch is higher than 95%.

Fatal

None

VMW Virtual Switch Credentials Invalid

Purpose

This rule monitors the accuracy of virtual switch credentials.

Scope

VMWVirtualSwitch.alerts

 
Table 74. Rule Definition
Conditions
State
Action

All monitored virtual switches have valid credentials.

Normal

None

The credentials for a virtual switch are invalid which prevents data collections for the configurations associated with that switch.

Fatal

None

 

Appendix: Alarm Messages

This describes the alarm messages generated by the VMware Performance Agent, and suggests possible solutions.

An error has occurred while attempting to connect to the vCenter. Please review the credentials used by the agent for accessing the vCenter.

Possible solutions:

•
Ensure the VMware Performance Agent properties contain a valid user name and password.
The user account configured for the agent does not have sufficient permissions to perform its collections. Please review the agent configuration and ensure the correct account is being used and that this account has the necessary permissions in the VMware environment.

Possible solutions:

•
Ensure the VMware Performance Agent credentials are configured to grant sufficient user permissions.
•
Ensure the user has sufficient permissions on the Virtual Center.
The agent was unable to connect to the vCenter. Please review the Host Name and Host Port in the agent configuration. If these are correct there may be issues in your network preventing the connection to the vCenter.

Possible solutions:

•
Incorrect host name
•
Ensure the VMware Performance Agent properties contain a valid host name.
•
Incorrect port number
•
Ensure the VMware Performance Agent properties contain a valid port number.
•
The specified host name does not resolve in DNS
•
Correct any DNS issues.
•
The specified IP address not reachable
•
Correct any network issues.
The agent was unable to connect to the vCenter. Please review the Host Name and Host Port in the agent configuration. If these are correct there may be an issue with the vCenter causing it to refuse connections. Please contact the administrator of the VMware environment to ensure the vCenter is operating normally.

Possible solutions:

•
Incorrect host name
•
Ensure the VMware Performance Agent properties contain a valid host name.
•
Incorrect port number
•
Ensure the VMware Performance Agent properties contain a valid port number.
An invalid Host Port value has been used in one or more attempts to connect to the vCenter. Please review your agent configuration to ensure proper connection information has been entered.

Possible solutions:

•
Incorrect port number
•
Ensure the VMware Performance Agent properties contain a valid port number.
The vCenter defined in the agent configuration is running a version that is not supported by this product. Please review the Host Name and Host Port in the agent configuration to ensure the connection settings point to the intended system. You may also need to contact your VMware administrator to ensure it is on one of the supported versions.

Possible solutions:

•
Update the vCenter to a supported version.
The agent is unable to find a route through the network to communicate with the vCenter. Please contact your network administrator to ensure that the Foglight, Agent (if separate), and vCenter systems are able to communicate or to resolve other network issues that may be resulting in this issue.

Possible solutions:

•
Incorrect host name
•
Ensure the VMware Performance Agent properties contain a valid host name.
•
Incorrect port number
•
Ensure the VMware Performance Agent properties contain a valid port number.
•
The specified host name does not resolve in DNS
•

The agent has entered an invalid state and is unable to proceed with normal operation. This situation may be self-correcting. However, if you continue to see this message, please deactivate the agent and then reactivate it one or two minutes after deactivation completed. If the situation continues please contact Quest Support.

Possible solutions:

•
If alarm reoccurs, contact Quest Support
The agent was unable to establish a secure SSL connection to the vCenter. Please review your agent configuration to ensure proper connection information has been entered.

Collecting performance data for one or more specific entities has caused the performance data request to the vCenter to fail. No further performance data will be collected for these entities. Please review the status of these entities in the VMware Environment and address any serious issues that may have occurred. Once the entities are operating normally, they can be removed from the Agent-Managed Blacklisted Entities list and performance data collections will resume for the entities. Consult the VMware Monitoring in Foglight for Storage Management documentation for the procedure for removing an entity from the Agent-Managed Blacklisted Entities list.

Possible solutions:

•
Resolve any errors with these entities in the virtual environment.
Collecting performance data for 25 or more specific entities has caused the performance data request to the vCenter to fail. Due to the size of this number it is likely that an issue with the virtual environment is the root cause and these entities are not specifically at fault. Please resolve any known environment issues. If the situation continues, please contact Quest Support.

Possible solutions:

•
Resolve any known environment issues.
An unexpected issue occurred during data collection from the vCenter. Please review your environment to ensure that data collection has resumed in a normal fashion. If there is a persistent problem or this message recurs regularly please contact Quest Support.

Possible solutions:

•
Confirm that the VMware data collection resumed after the issue was encountered by the agent. If the Foglight for Storage Management installation is not receiving VMware monitoring data or this message occurs regularly, contact Quest Support.
