I have used Splunk to threat hunt many times and have aspirations to build a distributed Splunk instance in the feature. I decided to start learning the installation, configuration, and deployment process of Splunk, by building a standalone instance. I get to a point where I think I have completed all the steps necessary to have a functioning Splunk set up. (connections are established on 8089 and 9997) and my web page is good. As soon as my apps are pushed to my (client)  this is when Splunk starts throwing an error stating indexers and ques are full. it also appears I am getting no logs from my applications. Any help is greatly appreciated. 

I am using the below query to merge 2 queries using append. However, I am unable to get the value of the field named "Code" from the first query under | search "Some Logger" printed in the Statistics section: index=* sourcetype=* host=* | search "Some Logger" | rex "LoggerName\|(?<time>\w+)\|(?<Service>\w+)\|(?<Type>\w+)\|(?<brand>\w+)\|(?<template>\w+)\|(?<hashId>[\w-]+)\|(?<Code>\w+)" | table Code | append [ search host=* | search "LoggerName2*" | rex field=_raw "field1=(?<field1>)\}" | rex field=_raw "field2=(?<field2>)," | rex field=_raw "field3=(?<field3>[a-zA-z-_0-9\\s]*)" | rex field=_raw "(?<field4>[\w-]+)$" | rex field=_raw "field5=(?<field5>)," | rex field=_raw "field6=(?<field6>)," | table field1,field2 ] The result from the 2nd/child query i.e. | search "LoggerName2*" is printing just fine in a tabular format. Value of the code field is API response code i.e. can be either 2XX, 3XX, 4XX, 5XX. Could someone please help ? Thanks!
