Marvel 2.0 - Index Template Override

Does kibana/marvel handle overriding the default index template e.g. to raise the shard value? I tried doing this the other day only to find that kibana/marvel could no longer find the cluster and I started to see Serialization exceptions in the elasticsearch client node logs.

After deleting the template and restarting the cluster, created according to the guidance shown here, though with a different name:

...the cluster was discovered again. However, I now have marvel running too few shards which will create its own problems.



You can create another index template on your monitoring cluster that matches the marvel indices prefix and that declares the number of shards/replicas you want, for example:

PUT /_template/marvel-with-shards 
  "template": ".marvel-es-2*", 
  "settings": {
    "index.number_of_shards": 7, 
    "index.number_of_replicas": 3

New indices created by marvel will match this template.

Unless you are dealing with large clusters creating big indices (ie 50GB a day and above), I wouldn't worry too much.
