Hi,

Thanks for the reply. Helped a lot. I also have a query about index rate

total. Is it

- no of documents indexed per sec
- no of indexing requests coming per sec
- no of indexing requests completed per sec

In my case i gave 42 files for indexing

{

"_shards": {

"total": 10,

"successful": 10,

"failed": 0

},

"_all": {

"primaries": {

"docs": {

"count": 48460,

"deleted": 0

},

"store": {

"size_in_bytes": 1089957,

"throttle_time_in_millis": 0

},

"indexing": {

"index_total": 42,

"index_time_in_millis": 1645,

"index_current": 0,

"delete_total": 0,

"delete_time_in_millis": 0,

"delete_current": 0

},

So what exactly does the graph of metric "Indexing request Rate" represnts.

Can you also provide any links to documentation about what each metric

exactly represents if possible.

Thanks,

sindhu.

Hi,

By the title, I assume you refer to the chart show in the Node Stats

dashboard. This one is tricky. It shows you the total spent on indexing per

second. This is best explained by an example - say you have 2 shards on a

node. Say that each indexes 100% of the time (continuously indexing) and

they do so in parallel. In this case we have 2 seconds of indexing (total

of two shards) for each real-world second. In other words - see this as a

load factor of indexing on the node.

Technically we indeed use the node stats api which gives you the total

spent on indexing of all shards that ever were on this node (reset on

restart).In your example it will be t1+t2+t3+t4 (if all shards were on that

node). The chart you see then plots the derivative (change per second) of

this value.

Hope this helps,

Boaz

Hi,

I'm new to Elasticsearch and marvel . I'm currently investigating

marvel and I want to know if the "Indices total indexing time" shown by

marvel is "sum of the times taken by each shard" or "time between the

arrival of request and completion of indexing".

For example if there are 5 shards and indexing request arrives at 's'

and indexing completes at 'e'. And shards take time t1,t2,t3,t4 and t5

respectively. So how is Indices total indexing time calculated now. Is ut

e-s or t1+t2+t3+t4+t5.

To add to this question, just want to know if marvel uses stats api.

Thanks.
