How to show an empty pie chart when all field values are zero?

[sachinlokulwar]

I have two fields as Used disk and Total disk, but right now, both fields are zero.
So, how can I show an empty pie chart as a rounded circle only?

What's the query you're using? There are several posts from the past which shows how to show a 0 values if the searches doesn't return any data. Some say about appendpipe OR append but it depends upon what your current search is that populates the pie chart.

search="sourcetype=aerospike stanza=cluster |table Total_bytes_disk Used_bytes_disk | transpose"|token_safe

I use the above query,But i doesn't get anything on my dashboard

If you use chart, and select the Pie visualization, you should get an empty circle when there are no events. Use this search exactly and you will see what I mean:

|noop|chart count

[woodcock]

The noop was just to create a run-anywhere search that shows 0 for count; it is not a command that will be of any use to you. Why don't you switch from a Pie chart to a Marker Gauge visualization and use a search like this instead:

sourcetype=aerospike stanza=cluster | eval Percent=100*(Used_bytes_disk/Total_bytes_disk) | fields Percent

This is a much more appropriate and powerful infographic, IMHO.

It will work with count only.How can I show values with this

sourcetype=aerospike stanza=cluster |table Total_bytes_disk Used_bytes_disk | transpose

for this query how can I use the |noop
