Known Affected Versions:
6.1.0, 7.0.0,,, 7.1.0,,,, 7.1.6,, 7.1.7,,, 7.1.8,,,,,, 7.1.9,,,

Opened: Aug 05, 2019

Severity: 3-Major


Data Collection Device (DCD) cluster fails to collect data or respond to queries causing issues with event collection and visualization.


DCD and visualization becomes inoperative.


If one or more of the DCDs becomes unreachable from the BIG-IQ or other DCDs due to networking, restarting, or other environmental issues, it is possible that the DCD cluster can become unhealthy and unable to respond to inbound data or query requests. Issues like excessive memory usage or network instability can trigger these erratic changes.


If data backups (snapshots) or data loss is acceptable then: -- Stop elasticsearch process on BIG-IQ and each DCD by typing the command: bigstart stop elasticsearch -- Delete the contents of /var/config/rest/elasticsearch/data directory on the devices by typing: rm -rf /var/config/rest/elasticsearch/data/* -- Restart elasticsearch process on BIG-IQ and each DCD by typing: bigstart start elasticsearch
