Resolution:
- Login to your MAA appliance via ssh or local console using the g2 user
- Edit the file /etc/mag2/health.conf
- Go to the end of the [redis] section and look for duplicate entries like in this example:
[redis]
enabled = False
query_interval = 30 # in seconds
max_fragmentation_ratio = 3
min_fragmentation_ratio = 0.8
max_memory_usage = 1073741824
max_connection_rejects = 200
min_changes_since_last_save = 1
bgsave_time_sec = 10
max_durable_connections = 1000
max_volatile_connections = 50
max_durable_connections = 1000
max_volatile_connections = 50
- Remove the duplicate lines, save the file and execute the following commands:
python -m norman.fabric health --restore_rules
sudo supervisorctl restart df-health-monitor
- The health monitor will now be started and the UI shows a green health state again.
