I wanted to index logs from Web/application server and do all the search, report, alert from my machine. How this can be done? Either i need to install a Splunk instance where the server is placed or how to get connected.
You need a forwarder to forward the data from applicaion server, an indexer to store the data and a search head to search it. All can be in a single machine or in three different machines or in a cluster.
It's difficult to provide a short answer. You have to decide and design your splunk deployment based on what you want to ingest , how and how much
