Plotting Each element of a Json

[rai4shambhavi]

so my log lines look something like this

<<METRIC-START>>{"A":332,"B":45,"C":67,"D":23,"E":234,"F":435,"G":43,"H":66,"I":32,"J":67,"K":21,"L":678,"M":45,"N":56}<<METRIC-END>>

It is in form of a Json and I am able to extract the fields along with time using this

| rex field=line "(?<=<<METRIC-START>>)(?<importMetrics>.*)(?=<<METRIC-END>>)"
| spath input=importMetrics

now I wish to plot A,B,C,D as timecharts, so I will have to give this command

| timechart span=1h
max(A) as A,
max(B) as B....till Z


So the whole query works fine but I wanted to know if there is anyshort way of doing it


| rex field=line "(?<=<<METRIC-START>>)(?<importMetrics>.*)(?=<<METRIC-END>>)"
| spath input=importMetrics
| timechart span=1h
max(A) as A,
max(B) as B....till Z

Given that you only appear to be interested in the fields in importMetrics, you can remove the other fields and then use wildcards

| rex field=line "(?<=<<METRIC-START>>)(?<importMetrics>.*)(?=<<METRIC-END>>)"
| spath input=importMetrics
| fields - line importMetrics
| timechart span=1h max(*) as *
