Utilities for working with the ELK (Elasticsearch, Logstash, Kibana) stack
This script is for easily adding and removing nodes from a running Elasticsearch cluster by including or excluding the node from every index that exists on the cluster.
It uses exclude._host and include._host to manage which Elasticsearch nodes
are available to shards.
Before running this script, add or remove the nodes from your ES cluster settings and mapping templates as needed.
To remove a node from the cluster:
./elkvacuate.rb -a evacuate -h nodetoremove.example.com -u elkmaster.example.com -p 1234
To add a node to the cluster:
./elkvacuate.rb -a invacuate -h nodetoremove.example.com -u elkmaster.example.com -p 1234
This script copies the mapping for a specific type from today's index in
Elasticsearch, and puts it into tomorrow's index.
The index for tomorrow is created if it doesn't exist.
Run as:
copy_index_mapping.py --host <hostname> --index-prefix logstash -t <type>
If you have multiple masters and schedule this script to run on all of them, you
can use the -o switch to ensure it only gets executed on the host which is the
current cluster master.
There is currently no support for authentication.
This directory contains example roles, cookbooks, and data bags that can be used to provision and maintain an ELK cluster relatively easily. These Chef code samples are for example purposes only; they are provided as-is and no plans are made to maintain or update them.
This directory contains an example script containing commands that can be used with an irc bot such as irccat for monitoring and managing an Elasticsearch cluster. These commands are mostly wrappers around Elasticsearch's API. These code samples are also provided as is for example purposes only, and will not be maintained or updated.
