This section covers how to use the Marvel dashboard to better understand the state of your cluster.
To make monitoring our cluster more interesting, we'll stream more Twitter data into it using the stream2es program, and run random queries against the index using a custom bash script described in this section.
See Chapter 3, Elasticsearch-head and Bigdesk for detailed instructions on how to install and use stream2es, but, for quick reference, start stream2es using the following command:
./stream2es twitter --target http://elasticsearch-node-01:9200/twitter/status
Next, we'll simulate user interactions by running random queries against the twitter index. Create a new bash script called run_queries.sh with the following content:
#!/bin/sh
# Path to dictionary file
DICTIONARY_PATH=/usr/share/dict/words
ELASTICSEARCH_URI=http://elasticsearch-node-01:9200/twitter
# Total dictionary words
TOTAL_WORDS=`wc -l $DICTIONARY_PATH | awk '{print $1}'`
while :
do
