In the MCP 2019.2.3 maintenance update, Mirantis introduces the following enhancements for StackLight LMA:

To obtain the enhancements, follow the steps described in Apply maintenance updates.

Open vSwitch monitoring

Enhanced Stacklight LMA to monitor the Neutron Open vSwitch (OVS) memory usage across nodes and raise an alert if the memory consumption of an OVS process exceeds the predefined thresholds, by default set to 20% and 30%.

SSL certificates monitoring

Enhanced StackLight LMA to monitor SSL certificates and raise an alert when a certificate is due to expire to allow for generating a new certificate or replacing the existing one on time. By default, the alerts raise if a certificate expires less than in 60 and 30 days.

Salesforce notifier improvement

Improved the Salesforce notifier service to properly handle the Salesforce requests timeouts.

SMART disks monitoring

Enhanced StackLight LMA to monitor physical disks that support Self-Monitoring, Analysis and Reporting Technology (SMART) and raise alerts if disk errors occur. By default, all disks on the bare metal servers are scanned.
