Display Query Memory

If you use LogScale to monitor your costs in terms of memory consumption, you can display the average memory allocated for your queries activity.

In the Search page, type this query in the Query Editor:
logscale
```
"direct memory allocated"
| group=query
| avg(bytes)
```
This search extracts the events having query as the value found for the group field, and uses the avg() function to calculate the average memory allocation of queries in the system, in bytes.
