UC Apps Reachability¶
Provider administrators and higher have access to the System Monitoring menus:
Unity Connection (
data/MonitoringCuc)Call Manager (
data/MonitoringCucm)HCMF (
data/MonitoringHcmf)LDAP (
data/MonitoringLdap)
The displayed data is the aggregated reachability and Round Trip Delay Time (RTT) for a UC app. Reachability is tested from all unified nodes.
The Interval indicates the configured time interval for the entry: hourly or daily.
Hourly intervals aggregate samples collected 15 minute intervals. Daily intervals aggregate hourly intervals.
The Start and End values are the time stamps for the interval. The difference corresponds with the selected Interval.
The Unified Node is the node name of the source unified node.
The Host name or IP is the IP addresses and port of the UC app.
Port 8443: HTTPS connectivity
The Avg TCP RTT (ms) is the average RTT in milliseconds over the interval for a successful connection.
The details of a data instance also show the maximum RTT (Max Tcp RTT) during the interval.
If the average RTT exceeds 400 ms, an alert is also triggered.
The Failures is the number of connection failures to the UC app Host name or IP over the interval.
For example, if the number of failures is 4 and the Interval is set to hourly, then all 4 reachability checks for the interval failed. Equally, if the interval is set to daily and all reachability checks failed, the value is 96 (24 x 4 hourly).
The details of a data instance with failures show the network error messages in the Errors group.
The Located At column shows the hierarchy of the UC app.
Failures would also generate alerts if an SNMP trap is configured.
