Hello is there a way to visualize the Disk Throughput using Lens?

I want to do a line graph but it seems like its not possible to do it with Lens.

Here's the fields:  
**`system.diskio.read.bytes`**

The total number of bytes read successfully. On Linux this is the number of sectors read multiplied by an assumed sector size of 512.

type: long

format: bytes

**`system.diskio.write.bytes`**

The total number of bytes written successfully. On Linux this is the number of sectors written multiplied by an assumed sector size of 512.

type: long

format: bytes

**`system.diskio.read.time`**

The total number of milliseconds spent by all reads.

type: long

**`system.diskio.write.time`**

The total number of milliseconds spent by all writes.

type: long

I'm surprised this didn't get hit by the 28 days later zombies. I am currently trying to work on this too, but I am thinking the system.diskio.io.time would cover both read and write time, but so far not getting good results.

Hi @Jesselastic

What version Elasticsearch?  
What / how are you collecting data? elastic Agent Metricbeat etc?  
Which exact fields?

and

What exactly are you trying to calculate?

Example with Elastic Agent

Quick Query Bar Filter

`data_stream.dataset : "system.diskio" and agent.name : "stephenb-metrics-test-es1" and metricset.name : "diskio"`

X - Axis Date Histogram

Y-Axis : `counter_rate(max(system.diskio.io.time))`

**IMPORTANT** : Breakdown by `system.diskio.io.name` to 20 or so because there is more than 1 disk name... if you do not do this your results will .... not... work....

You can collapse by `SUM` if you want the total or `none` if you want to see each disk... ... This is know as a series aggregation ... This is in the breakdown ... now this will sum up all the individual counter rates by `system.diskio.name` the different for the total sum.

Now you get a single like that is the SUM of all the indvidual disk ios

Here is the Mappings for Elastic Agent ...

So what exactly do you want?
