JSON element names contains dynamic part - how to create table

My JSON log file contains metrics - below message example. Json elements name and number are not fixed. As you can see element meters.bytesInPerSec.APPLICATION_NAME can be repeated for all applications dynamically.

How should I configure props.conf and how should I write query to get following table:

application, m5_rate
my-application-name-a, 0
my-application-name-b, 0
my-application-name-c, 18.081537604791322
my-application-name-d, 0

If such question was already answered please point me to proper doc/answer.

Eg message:
{
"time": 1512637302765,
"meters": {
"bytesInPerSec.my-application-name-a": {
"count": 0,
"m1_rate": 0,
"m5_rate": 0,
"m15_rate": 0,
"mean_rate": 0,
"units": "bytes/SECONDS"
},
"bytesInPerSec.my-application-name-b": {
"count": 0,
"m1_rate": 0,
"m5_rate": 0,
"m15_rate": 0,
"mean_rate": 0,
"units": "bytes/SECONDS"
},
"bytesInPerSec.my-application-name-c": {
"count": 152503217,
"m1_rate": 16.733471413145928,
"m5_rate": 17.948078497437745,
"m15_rate": 18.081537604791322,
"mean_rate": 39.63002548338987,
"units": "bytes/SECONDS"
},
"bytesInPerSec.my-application-name-d": {
"count": 0,
"m1_rate": 0,
"m5_rate": 0,
"m15_rate": 0,
"mean_rate": 0,
"units": "bytes/SECONDS"
}
}
}

Hi @pszpor,

You can achieve this via search query based on sample data you have provided please try below query (First 2 lines are used to generate dummay data)

| makeresults
| eval _raw="{ \"time\": 1512637302765, \"meters\": { \"bytesInPerSec.my-application-name-a\": { \"count\": 0, \"m1_rate\": 0, \"m5_rate\": 0, \"m15_rate\": 0, \"mean_rate\": 0, \"units\": \"bytes/SECONDS\" }, \"bytesInPerSec.my-application-name-b\": { \"count\": 0, \"m1_rate\": 0, \"m5_rate\": 0, \"m15_rate\": 0, \"mean_rate\": 0, \"units\": \"bytes/SECONDS\" }, \"bytesInPerSec.my-application-name-c\": { \"count\": 152503217, \"m1_rate\": 16.733471413145928, \"m5_rate\": 17.948078497437745, \"m15_rate\": 18.081537604791322, \"mean_rate\": 39.63002548338987, \"units\": \"bytes/SECONDS\" }, \"bytesInPerSec.my-application-name-d\": { \"count\": 0, \"m1_rate\": 0, \"m5_rate\": 0, \"m15_rate\": 0, \"mean_rate\": 0, \"units\": \"bytes/SECONDS\" } } }"
| spath
| rename meters.bytesInPerSec.my-application-name-*.m15_rate AS my-application-name-*
| table my-application-name*
| transpose column_name=application
| rename "row 1" AS m15_rate

I hope this helps.

Thanks,
Harshil
