Hi everyone.

I'm having an issue with my elastic instance whereby I can't get monitoring working. I've recently upgraded from 5.6 where I had monitor working on a trial xpack licence to 6.4 where I have the standard free licence. When I click the Monitoring link I get the usual "We couldn't activate monitoring" error. My cluster is currently a single node.

I can see the monitor indices are being created:

> green open .monitoring-es-6-2018.09.17 BDvrkfZPQmCxNna6cO\_fhg 1 0 9722010 15605 4gb 4gb  
> green open .monitoring-kibana-6-2018.09.15 CTwkSJeFR4qwQqRwPkqSiA 1 0 8639 0 2mb 2mb

I have researched and found some issues regarding cluster\_stats. I have ran this command:

> ```
> GET /.monitoring-es-6-*/_search
> {
> "size": 0,
> "query": {
> "term": {
> "type": "cluster_stats"
> }
> },
> "aggs": {
> "group_by_day": {
> "date_histogram": {
> "field": "timestamp",
> "interval": "day"
> }
> }
> }
> }
> 
> ```

And get this result:

> ```

> > "took": 1,
> > "timed_out": false,
> > "_shards": {
> > "total": 7,
> > "successful": 7,

> > "aggregations": {

> > "buckets": []
> > }
> > }
> > }
>

Any ideas how I could get monitoring working?

Thanks in advance.

FYI for anyone that comes across this issue. I was able to fix it by deleting the old .security index. When looking through the logs I could see:

```
`collector [cluster_stats] failed to collect data
java.lang.IllegalStateException: Security index is not on the current version. Security features relying on the index will not be available until the upgrade API is run on the security index
`
```
