NXT-21199 / CS2406725010
- Severity
- Minor
- First occurrence
- NXT 2.10.2
- Description
- In some scenarios, the CM Sibling Data Usage Graph does not show data when it is displayed in combination with other graphs in Analyze Modem View.
- Workaround
- None
NXT-21172 / CS2405714301
- Severity
- Minor
- First occurrence
- NXT 2.8.1
- Description
- A proactive scan on a fiber node where all cable modems are offline can take up to 20 minutes after "Scan Now" is clicked, and then result in an empty popup dialog.
- Workaround
- None
NXT-20832 / CS2405701157, CS2405707940
- Severity
- Minor
- First occurrence
- NXT 2.10.1
- Description
- A high number of newly detected alarms can lead to an increased rate of Solr publishing failures. These publishing failures are automatically retried and do not impact application functionality. However, they will trigger the currently configured alarm threshold for Solr failures.
- Workaround
- The Solr publishing failure alert can either be disabled or its threshold can be increased. Disabling or reconfiguring this alert does not significantly impact the detection of system-wide Solr issues, as it is one of several alerts designed to notify of serious Solr failures.
NXT-19128 / CS2207423996
- Severity
- Minor
- First occurrence
- NXT 2.8
- Description
- In No AC (Alarm Central) mode Analyze Modem view does not display the hierarchy path.
- Workaround
- None
NXT-21885 / CS2410775433
- Severity
- Info
- First occurrence
- NXT 2.11
- Description
- In AlarmCentral Historical graphs, turning on 10/50/90 Distributions for the entire fiber node causes an opaque white overlay over the graphs, obscuring the raw data series.
- Workaround
- None
NXT-20364 / CS2402673441
- Severity
- Info
- First occurrence
- NXT 2.7.5
- Description
- The change markers for the Upstream Modulation Overlay remain on graphs when a user changes to a new upstream channel on a different MAC Domain. This can cause markers for the wrong upstream channel to be displayed on the graph.
- Workaround
- None
NXT-14828 / CS2205399225
- Severity
- Info
- First occurrence
- NXT 2.7.5
- Description
- A modem's upstream FEC data can be missing in ServAssure NXT Network View and Alarm Central, including historical graphs, when it is unreachable by SNMP. This can occur even if the upstream data for the modem is able to be collected from the CMTS.
- Workaround
- Use ServAssure NXT Analyze Modem View to see the modem's upstream FEC data.
