No alarms from VNA are shown in Spectrum even after restarting the VNA aggregator, One of the VNA collectors and the Tomcat of the OneClick that is connected to VNA.
Checking the mysql processlist on the VNA servers shows the following:
mysql> show full processlist;
+----+-----------------+-----------+------+---------+------+------------------------+------+
| Id | User | Host | db | Command | Time | State | Info |
+----+-----------------+-----------+------+---------+------+------------------------+------+
| 4 | event_scheduler | localhost | NULL | Daemon | 4152 | Waiting on empty queue | NULL |
The network connection between Spectrum and VNA was broken and when restarted, Spectrum initiates a full synch. The current collection of the sdn_queu_size(150) will not accommodate the data load from 20 collectors at once.
