Hi @Vaishnavi_sahil ..may i know if this info/log is already loaded to splunk or not..
if not yet, then, i think thats an excel file, right.. so, please save it as a CSV file and then upload that data to splunk. once you loaded to splunk, then splunk query will be easy. for example (if you update us the field names, then query will be formulated):
index=nnm_logs | table Node_Name Node_Availability
