Edit the python.d/elasticsearch.conf
configuration file using edit-config
from the your agent's config
directory, which is typically at /etc/netdata
.
cd /etc/netdata # Replace this path with your Netdata config directory, if different, if different
sudo ./edit-config python.d/elasticsearch.conf
Sample:
local:
host : 'ipaddress' # Elasticsearch server ip address or hostname.
port : 'port' # Port on which elasticsearch listens.
node_status : yes/no # Get metrics from "/_nodes/_local/stats". Enabled by default.
cluster_health : yes/no # Get metrics from "/_cluster/health". Enabled by default.
cluster_stats : yes/no # Get metrics from "'/_cluster/stats". Enabled by default.
indices_stats : yes/no # Get metrics from "/_cat/indices". Disabled by default.
