Wildcard in Field Value for where clause

I am currently running this search to populate a table in a dashboard:

dedup clientcert sortby "-date" | where clientcert="$host_name$" | table partitions_*size

The hosts share some similar partitions, however most differ. I am attempting to only display the results that have values in them.

Please show sample data, existing search, and desired output.

I am trying to filter out the columns that are blank in this table. Desired output should only show if there is a value. This is also supposed to be automated and dynamic, changing when a new client is selected and has different partitions

Try this -

| rename COMMENT as "Move the where clause before the dedup for efficiency." 
| where clientcert="$host_name$" 
| dedup clientcert sortby "-date" 

| rename COMMENT as "Leave in the field clientcert to enable the untable command, and to allow multiselect later if you want."
| table clientcert partitions_*size

| rename COMMENT as "Pull all the PartitionNames and Values to individual lines"
| untable clientcert PartitionName Value

| rename COMMENT as "Kill the ones that are null, then put it all back together as a table with fewer columns."
| where isnotnull(Value)
| xyseries clientcert PartitionName Value

How would this be run where the PartitionName is unknown by the user?

You can use like or match function with where clause to specify wildcards in field values.

dedup clientcert sortby "-date" | where like(clientcert,"$host_name$%" | table partitions_*size

OR

dedup clientcert sortby "-date" | where match(clientcert,"$host_name$") | table partitions_*size

The search table still displays columns with data from other clientcert's
