The tools used for viewing and managing node labels in your InfluxDB Enterprise cluster are the [`influxd-ctl show` command ](/enterprise_influxdb/v1/tools/influxd-ctl/show/)and the [`influxd-ctl node-label` command and subcommands](/enterprise_influxdb/v1/tools/influxd-ctl/node-labels/). * [View node labels](#view-node-labels) * [Add labels to a node](#add-labels-to-a-node) * [Update node labels](#update-node-labels) * [Delete node labels](#delete-node-labels) * [Programmatically access node labels](#programmatically-access-node-labels) ## View node labels Use the [`influxd-ctl show` command](/enterprise_influxdb/v1/tools/influxd-ctl/show/)to view information about nodes in your InfluxDB Enterprise cluster, including node labels. ```sh influxd-ctl show ``` [](#view-example-influxd-ctl-show-output) View example `influxd-ctl show` output ``` # Data Nodes ID TCP Address Version Labels 4 data-node-01:8188 1.12.4-c1.12.4 {"az":"us-west"} 5 data-node-02:8288 1.12.4-c1.12.4 {"az":"us-east"} # Meta Nodes ID TCP Address Version Labels 1 meta-node-01:8191 1.12.4-c1.12.4 {"az":"us-west"} 2 meta-node-02:8291 1.12.4-c1.12.4 {"az":"us-east"} 3 meta-node-03:8391 1.12.4-c1.12.4 {"az":"us-west"} ``` ## Add labels to a node To add a label to a node in your InfluxDB Enterprise cluster, use the[`influxd-ctl node-labels set` command](/enterprise_influxdb/v1/tools/influxd-ctl/node-labels/set/)and include the following flags: * **-nodeid**: Node ID to add the labels to * **-labels**: JSON object of label key-value pairs ```sh influxd-ctl node-labels set -nodeid 4 -labels '{"az":"us-east","team":"amer"}' ``` [](#view-influxd-ctl-show-output-with-added-labels) View `influxd-ctl show` output with added labels ``` # Data Nodes ID TCP Address Version Labels 4 data-node-01:8188 1.12.4-c1.12.4 {"az":"us-east","team":"amer"} 5 data-node-02:8288 1.12.4-c1.12.4 {} # Meta Nodes ID TCP Address Version Labels 1 meta-node-01:8191 1.12.4-c1.12.4 {} 2 meta-node-02:8291 1.12.4-c1.12.4 {} 3 meta-node-03:8391 1.12.4-c1.12.4 {} ``` ## Update node labels To update node labels, use the[`influxd-ctl node-labels set` command](/enterprise_influxdb/v1/tools/influxd-ctl/node-labels/set/)and include the following flags: * **-nodeid**: Node ID to update the labels on * **-labels**: JSON object of label key-value pairs to update ```sh influxd-ctl node-labels set -nodeid 4 -labels '{"team":"emea"}' ``` *Only label keys included in the `-labels` JSON object are updated.
