Foglight Net Monitor Known Issues

The following is a list of Foglight Net Monitor issues known to exist at the time of this Foglight Infrastructure Utilities release.

Defect ID

Known Issue

AGENT-3356

Duplicate "Monitor Location" values displaying on Single Device Summary on HA primary FMS.

AGENT-3345

Redesign the Net Monitor reports.

AGENT-3258

It is not suitable to limit the packet size to larger than 40 bytes in UI, should find another better way.

AGENT-3122

Add the ability to select existing hosts, monitored by other agents.

AGENT-2852

The Single Location Summary page times out when a high number of devices is monitored by a single location.

Workaround: You can monitor a maximum of 3,000 devices from a single location. Each device should be monitored from one location only.

AGENT-2747

On SUSE® Linux® 10 or lower version [os command icmp] TraceRoute failed with java.lang.Exception: Stack Trace.

AGENT-2700

Devices belonging to different LANs, with the same IP address but having different network IDs, are merged into the same Device Wrapper object.

Workaround: Provide different override names for the merged network devices.

AGENT-2658

The Net Monitor Agent does not support monitoring devices through a Round Robin DNS or DDNS name.

Workaround: Do not use a Round Robin DNS or DDNS name as a device name.

AGENT-2531

The response time, availability, and packet loss data are not consistent during the first time range period when the agents begin data collection. After the first time range period (four hours by default), the collected data becomes accurate.

Workaround: Upgrade the Management Server to a version later than 5.6.11 (when available).

AGENT-2449

Specifying an IP address as the target device name in the Net Monitor Agent Properties requires the agent to resolve the DNS name using the provided IP address. In some environments this result in a failure when the reverse DNS entry for a device is not configured properly.

Workaround: Ensure that both forward and reverse DNS entries for the specified host are configured. If this does not work, use the device DNS name as the Device name override agent property value.

AGENT-2446

Two network device entries in the Net Monitor Agent properties pointing to the same device do not trigger the Duplicated monitor on same IP Device rule. This is because one entry points to the device using the host name, while the other uses the IP address.

Workaround: There is no workaround for this issue.

AGENT-2108

NetMonitor agent doesn't support IPv6 IP address.
