Couldn't Activate Monitoring in 6.3

Elastic Stack Kibana
1

Following a 6.1 to 6.3 upgrade, monitoring within Kibana now shows an error message:

"We couldn't activate monitoring"

I've added the following two lines to my Elasticsearch.yml:

xpack.monitoring.enabled: true
xpack.monitoring.collection.enabled: true

The only error I'm seeing is in the kibana.stderr file and seems to indicate an index is read only?

Has anyone else run into this issue?

OK, self healed it... But for anyone else searching this error, refer to this thread:

In short, due to some space issue, it appears the indices were put into read only mode. My Kibana index was set as such so this console command fixed it:

PUT your_index_name/_settings
{
"index": {
"blocks": {
"read_only_allow_delete": "false"
}
}
}

Other indices may also be in that state so I'll check.
